The REGO-FIX standardized MQL PG collets are designed for tool shanks according to DIN 69090-3 and available for HSK-A 63 and HSK-E 40 toolholders. They are designed for machines using one-channel, internal through-spindle MQL systems and are beneficial for virtually any machining application.

The C3 series of MEGA NEW BABY chucks has a clamping range of 0.010” to 0.630” with a maximum RPM of 30,000. The chucks are said to be ideal for drills, reamers, taps and finishing end mills. Ultra-slim and strong, they provide reliable gripping for even the smallest workpieces.

At my peak, I was consuming (blue line) 71% more electricity than similar homes (black line) in my area and even more than similar efficient homes (green line).

Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.

Machining and measuring to exacting standards. Four basic considerations are: dimensions, or geometrical characteristics such as lengths, angles and diameters of which the sizes are numerically specified; limits, or the maximum and minimum sizes permissible for a specified dimension; tolerances, or the total permissible variations in size; and allowances, or the prescribed differences in dimensions between mating parts.

All T.J. Davies custom retention knobs are manufactured from American-made 8620 alloy steel, which has a high tensile strength to withstand strong centrifugal force, high load force and high feed rate. All knobs are machined in-house with single point threading to Imperial (Class 2A UNC) or Metric (Class G6) standards. After threading is completed, each component is heat treated to 58-62 HRC then treated with hot black oxide to military specifications for protection against corrosion.

It’s important to note that I don’t live where it freezes in the winter, so I don’t have to worry about frozen pipes. That gives me tremendous flexibility in how I heat my home. In the winter months, I turned my thermostat down to 64 degrees and bundled up. Since my thermostat was usually set to 68 degrees, the slight adjustment in the temperature did little to reduce my energy bills. So instead, I turned the heat off and used a space heater in my office during the day and then turned on the heat in the afternoon for the family. The results were fantastic: I was using 49% less gas than similar homes in my area.

To avoid interference with workpiece contours, the lengths of DirectCooling Series holders are ideally matched to one another and offer optimal stability and unlimited flexibility. This flexibility is further enhanced with the HSK-T universal standard interface for turning tools that ensures a straightforward connection to multifunction machining centers, such as those performing both milling and turning operations.

The taper angle provides increased gripping power as the SK collet chuck’s 8-degree collet seats deeper in the body of the holder, providing double the clamping force and precision than traditional 16-degree collets. The narrow body of the SK collet chuck allows for access to tight spaces and provides better clearance making it ideal for machining complex parts.

Takezawa Seiki's floating holder eliminates variations in quality and load on the tool by maintaining a constant transmission torque, according to the company.

REGO-FIX recently added minimum quantity lubrication (MQL) machining to its powRgrip (PG) toolholding system to help shops improve production and tool life by reducing coolant consumption and shortening cycle times.

The holder provides targeted clearance face cooling for efficient chip control and increased tool life in addition to high precision cooling on the flank face to slow down insert heat and wear. The holders feature a flexible coolant connection in three positions for either external plumbing or thru-coolant introduction through lathe turrets.

CERATIZIT recently enhanced its new MaxiLock-N turning toolholders by incorporating the company’s DirectCooling technology.

The advanced design of the SK collet chuck provides increased rigidity and gripping force as well as the ability to reach tight spaces. A special heat treatment, grinding and custom slotting process enables Lyndex-Nikken to guarantee a 5 micron run-out tolerance for their "on size" fractional and metric size precision collets.

MQL machining is a clean, sustainable manufacturing technique that directs an aerosol of compressed air and a minimal amount of cutting oil (<50 ml/h) directly to the cutting area. In addition to significantly reducing coolant consumption, MQL machining reportedly reduces cycle times anywhere from 25% to 85%, while also improving chip evacuation for better surface finish and tolerance, and increasing tool life.

I’m closing the gap. I’m now even with similar homes in my area but still have a long way to go, as I’m 59% higher than similar efficient homes.

With its new Walter Turn Swiss toolholders for turning applications, the company is targeting applications on Swiss-style automatic lathes and multi-spindle machines that have up to 2,175 psi (150 bar) of coolant pressure. The holders are suitable for turning high-precision parts, longitudinal (axial) turning, facing and copy turning small-diameter components.

Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.

Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

I have lived in California for over 20 years, and every month I get a report from Pacific Gas and Electric Company (PG&E) on my energy consumption. For years, I told myself the bill was not comparing apples to apples. Many of my neighbors have solar panels on their roofs. I figured that my usage was so much higher because I lived in one of the few houses on my street that did not have an alternative source of energy. In my best months, my energy use was easily 25% to 30% higher than in similar homes. In my worst months, well, it was embarrassing.

The MaxiLock-N turning toolholders incorporate two internal coolant holes that aim coolant directly at the cutting edge to prevent wear and ensure stable processes. Using these coolant holes, nozzles direct coolant to the clamping flat from above as well as from below to the flank. This additional flank cooling contributes to the tool’s ability to extend tool life by 60% compared to tools that cool only at the clamping flat.

Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.

With the introduction of its C3 program, BIG DAISHOWA recently expanded its BIG CAPTO toolholder line with the introduction of its C3 program, which is designed to increase efficiency and precision for small lathes.

Turning machine capable of sawing, milling, grinding, gear-cutting, drilling, reaming, boring, threading, facing, chamfering, grooving, knurling, spinning, parting, necking, taper-cutting, and cam- and eccentric-cutting, as well as step- and straight-turning. Comes in a variety of forms, ranging from manual to semiautomatic to fully automatic, with major types being engine lathes, turning and contouring lathes, turret lathes and numerical-control lathes. The engine lathe consists of a headstock and spindle, tailstock, bed, carriage (complete with apron) and cross slides. Features include gear- (speed) and feed-selector levers, toolpost, compound rest, lead screw and reversing lead screw, threading dial and rapid-traverse lever. Special lathe types include through-the-spindle, camshaft and crankshaft, brake drum and rotor, spinning and gun-barrel machines. Toolroom and bench lathes are used for precision work; the former for tool-and-die work and similar tasks, the latter for small workpieces (instruments, watches), normally without a power feed. Models are typically designated according to their “swing,” or the largest-diameter workpiece that can be rotated; bed length, or the distance between centers; and horsepower generated. See turning machine.

Process of both external (e.g., thread milling) and internal (e.g., tapping, thread milling) cutting, turning and rolling of threads into particular material. Standardized specifications are available to determine the desired results of the threading process. Numerous thread-series designations are written for specific applications. Threading often is performed on a lathe. Specifications such as thread height are critical in determining the strength of the threads. The material used is taken into consideration in determining the expected results of any particular application for that threaded piece. In external threading, a calculated depth is required as well as a particular angle to the cut. To perform internal threading, the exact diameter to bore the hole is critical before threading. The threads are distinguished from one another by the amount of tolerance and/or allowance that is specified. See turning.

T.J. Davies Co. Inc., Mantua, Ohio, produces custom retention knobs, pull bolts and other workholding components and accessories to fit older, or obsolete machinery. All dimensions of knobs can be customized, including length, diameter, thickness of collars, dimensions between collar and knob end, thread size, and more.

If someone wants to use an appliance, they must turn it on at the power strip or ask Alexa to turn it on (try remembering what you named 100 devices in your home — now that is a good memory trick!). What I found the most interesting about this part of my experiment was that I have devices that are all branded as energy-saving devices, yet my energy consumption was most affected by turning off these trickle devices (commonly called wall warts). Most of the devices are not being used throughout the day, but the lying-in-wait electricity consumption certainly contributed to a sizable portion of energy waste in my household.

Additionally, customers can specify a coolant hole, taper style, and whether O-rings are required. Custom made retention knobs are sized to fit the machine tool and spindle or toolholder to maximize the toolholder’s performance and cutting tool life and extend the life of existing machine tool assets.

The BIG CAPTO C3 square holders for turning applications come in left- and right-hand orientations. The C3-180-BH16R-2058 and C3-180-BH16L-2058 mono-block holders feature insert clamps that enhance rigidity and minimize vibrations and movement during cutting.

The FHN Series is available in North America by visiting this online shop: https://SocalSpecialtyTools.com. Available models include the FHNS12C1 12 mm Shank with ER20 Collet and the FHNS25C2 25 mm Shank with ER32 Collet.

In the summer, I bought an outdoor smart thermostat. Using an app, I was able to create a script that notified me when the temperature outside went below 76 degrees. Instead of continuing to run the air conditioner at night, I switched to using fans to bring in the cool evening air. In the morning before the temperature went back up, I would close the house up again. At the same time, I turned my thermostat up to 79 degrees so that the air conditioner typically only turned on in the late afternoon for a few hours when it was hot.

Added to titanium-carbide tooling to permit machining of hard metals at high speeds. Also used as a tool coating. See coated tools.

This experiment was triggered by the visibility provided by PG&E in my monthly bill. Had I not known that I was using more energy than similar homes in my neighborhood and been a highly competitive individual, I would not have pursued making changes in my environment. The cost savings that I have achieved — at a time when energy prices are going up — are an added benefit.

Designed specifically for one-pass honing, the FHN Series method compensates for small offsets such as tilt between the center axis of the tool and the pilot hole. By correcting the offset that occurs when attaching and detaching tools with the holder, it is now possible to achieve higher precision machining, according to the company.

Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.

I made sure to upgrade my large appliances — including the washing machine and dryer, dishwasher, and refrigerator — to energy-efficient devices. In addition, I run the devices on their shortest cycle or lowest setting, start my laundry as early in the morning as possible, and run the dishwasher at night, thus saving the energy crunch that we always experience here in California from 4 p.m. to 9 p.m. when people arrive home from work. I even turned off the power to my garage door opener. It may have been a bit of an inconvenience to come inside every time I want to open it, but that occasional inconvenience is well balanced with not using electricity 24/7 on the off chance that I may want to open the garage door.

Earth Day is this Friday, April 22. As such, I wanted to take a break from my normal IT service management/knowledge management coverage to discuss my journey to reduce my carbon footprint using smart technologies.

Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.

With these smart devices, IoT power strips, and apps that allow you to create routines that focus on reducing consumption, consumers can make a real difference in their carbon footprint. I spent around $600 on various technology solutions around my home and have significantly reduced my energy consumption — both natural gas and electricity.

Potential benefits include less downtime caused by bird nesting of chips thanks to the targeted clearance face cooling and long tool life even when turning heat-resistant workpiece materials due to the cooled cutting edge.

Now I’m using 48% less gas than efficient similar homes in my area. This was a substantial change, and compared with other households, I was using a lot less natural gas.

Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.

In tensile testing, the ratio of maximum load to original cross-sectional area. Also called ultimate strength. Compare with yield strength.

Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.

Essentially a cantilever beam that holds one or more cutting tools in position during a boring operation. Can be held stationary and moved axially while the workpiece revolves around it, or revolved and moved axially while the workpiece is held stationary, or a combination of these actions. Installed on milling, drilling and boring machines, as well as lathes and machining centers.

In honing, where very high precision is required, even small deviations between the center of the tool and the center of the pilot hole can have a significant impact on machining accuracy, quality and tool life.

The new Takezawa-Seiki FHN Series floating holders from Japan USA Precision Tools, Bellflower, California, are said to follow the smallest offset to improve single-pass honing accuracy and extend tool life.

In many cases, chamber and cross-section areas within a toolholding system create turbulence that causes an irregular air/coolant mix ratio in the aerosol. However, the REGO-FIX PG MQL solution uses a coolant tube fitted with a lance that directs the mixture through the collet and directly to the tool for reliable coolant distribution at the lowest consumption rate.

In April, I will be adding solar panels with a Powerwall and exploring replacing all the natural gas devices. Reducing my carbon footprint is more of a journey than a destination. For now, it’s an inconvenience to wait until my cable box powers up and reconnects to my provider, but the energy I save each day is well worth the wait. What steps have you taken to reduce your carbon footprint? Share your ideas, and maybe we can collaborate and find new solutions for improving our relationship with the Earth.

C3 boring bar holders also are available to clamp 6 mm, 8 mm, 10 mm or 12 mm boring bars. All turning toolholders feature through-spindle coolant.

It’s time for us to rethink how we build homes and how we introduce consumer devices into those homes. If we want to see a real difference in affecting climate change and reducing our carbon footprint, it will take a lot more than just reducing the consumption of natural and renewable energy. It will take redesigning our home and office experience to one that learns how we consume energy and optimizes and reduces that consumption. We need to turn our home and office spaces into learning systems that measure, analyze, and adjust how we use our natural resources.

Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.

An advanced design of SK collet chucks from Lyndex-Nikken, Mundelein, Illinois, are said to optimize machine tool performance by requiring fewer collet chuck changes and improved workpiece surface finish.

Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.

The holders accept CCGT3xx, DCGT3xx and VCGT2xx indexable inserts and provide a high level of indexing accuracy even when turning parts with tight tolerance specifications. The short head dimension enables short clamping and high stability. The shank dimensions are 12 mm × 12 mm and 16 mm × 16 mm.

A titanium nitride (TiN) bearing nut improves rigidity as the uniquely designed gold ring reduces collet damage and micro vibration with the collet flange, according to the company. It also eliminates friction with the collet.

As smart devices become even more innovative, consumers will have increasing control over their surroundings and become more knowledgeable about their impact on the world. Today, new systems allow homeowners to monitor their electric devices at the fuse box. With a small upfront investment and the data and analysis to know what to change, individuals can make a real difference in how they consume our natural and renewable energy sources. Additionally, we will need to focus on how to secure the data that is collected to reduce the risk associated with IoT.

During the pandemic, I began to obsess over my numbers. Each month when the bill arrived, I got increasingly focused on how to bring my consumption below my neighbors. I progressively tried new ideas and new devices to reduce my carbon footprint. From all of my changes and attempts to make a difference, two options gave me the best results.

The new square toolholders are available in 90° and 180° types. The 90° type offers a variety of orientations, including perpendicular to the workpiece. Its compact design also allows for work in spaces that are tighter or have limited clearance. The 180° type allows the tool to machine harder-to-reach areas of the workpiece.

With my heating and cooling under control, I turned to all those devices around the house that sat there sipping away at the current even though they were not being used. I purchased a smart power strip for every room and plugged in as many devices as I could. Each socket had its power switch, thus allowing me to control what was on or off throughout each room from a single device. The next step was to link them to a central control device and create a routine. Every evening, I ask my Alexa device to “end my day,” and with one command all the trickle feed devices throughout the house are turned off. This includes computers, TVs, cable boxes, Apple TVs, DVDs, printers, shredders, gaming devices, coffee pots, toasters, lamps, lights, and even the treadmill. And then in the morning, I tell Alexa to “start my day,” powering up only my office and leaving the rest of the house completely shut off.
