How does your Self-Centering Vise maintain accuracy over time?

The centering accuracy is ±0.005 mm, thanks to a hardened, precision-ground leadscrew and nut. The nut is also adjustable for backlash—so after years of use, you can take out any slack and bring the vise back to its original accuracy instead of replacing it.

Q: What materials are your core components made from and what is their hardness?

Clamping pins, receivers, and other wear parts are made from high-hardenability alloy steel, then heat-treated to HRC 58–62. That hardness keeps the seating surfaces accurate over thousands of cycles.

Q: How does the self-cleaning function work in your automation chucks?

There are air-blast channels built into the chuck body. When the system unclamps, a burst of high-pressure air blows chips and coolant off the tapered pins and receivers. That way the next pallet seats cleanly every time—important if you're running unattended.

Q: Do you offer customized workholding solutions for unique applications?

Yes. We do a lot of custom work alongside the standard product line. Send us your part drawing, machine model, and production volume and our engineers will propose a fixture design. We handle everything from concept to finished hardware.

Q: For 5-axis machining of thin-walled or delicate parts, what workholding do you recommend?

Take a look at our Dovetail Fixtures. They grip just 3 mm of stock in a dovetail profile, so the clamping force goes downward instead of squeezing the walls. You get 5-side tool access with very little risk of distortion—works well for aluminum housings, titanium brackets, and similar thin-walled parts.

NEXTAS zero-point clamping system for precision CNC workholding

01What is the repeatability of your zero-point systems?

Selected product series deliver repeatability down to <0.003 mm, and every shipment is verified on certified CMM equipment before it leaves our factory.

02What materials are your core components made from and what is their hardness?

Clamping pins, receivers and other wear parts use high-hardenability alloy steel, then receive heat treatment to HRC 58–62 for long-term seating accuracy.

03How does the self-cleaning function work in your automation chucks?

Built-in air-blast channels clear chips and coolant from the tapered pins and receivers during unclamping, helping the next pallet seat cleanly.

04Do you offer customized workholding solutions for unique applications?

Yes. Share the part drawing, machine model and production volume. Our engineers can develop the fixture concept and manufacture the finished hardware.

05For 5-axis machining of thin-walled or delicate parts, what workholding do you recommend?

Take a look at our Dovetail Fixtures. They grip just 3 mm of stock in a dovetail profile, so the clamping force goes downward instead of squeezing the walls. You get 5-side tool access with very little risk of distortion.

06How does the self-centering vise maintain accuracy over time?

A hardened, precision-ground leadscrew and adjustable nut support centering accuracy of ±0.005 mm and allow backlash to be corrected after extended use.
