What are the benefits to using a Modular Fixture Plate on a CNC machine?
Modular fixture plate benefits include:
- Increasing the workholding, clamping and setup area
- Convenience of having hundreds of bored and tapped holes versus a few t-slots
- Indexing, shifting, locating and holding large parts
- Clamping large parts outside of the machining envelope
- Using the SMW Mod Vise low profile, modular work holding system!
- Protecting the CNC machine table (often made from soft cast iron)
- Quickly aligning, tramming, and clamping vises and other workholding
- Using custom, hot-swappable fixture plates tops
Should I buy an aluminum or steel Fixture Plate?
We only offer aluminum fixture plates for the Tormach line (440, 770, 1100). We do not offer custom aluminum fixture plates due to the batch size require for hardcoat anodizing.
What is the Fixture Plate hole spacing?
Standard SMW fixture plate holes are spaced 1.25" on center
Is each hole bored and threaded?
Yes, each hole is precision bored 0.25" deep for use with a 1/2" dowel pin, the SMW Mod Vise or other 1/2" accessories. Below the precision 1/2" bore, each hole is tapped 1/2x13.
What Torque Specs should I use on the Fixture Plate?
We recommend 60 ft-lb (81 N-m) for the low-profile SHCS that secure the fixture plate to the T-Nuts.
The appropriate torque when using the fixture plate for workholding depends on a variety of factors, including the thread engagement of the stud or screw into the fixture plate.
For the 1/2x13 holes in aluminum plates, we recommend up to 45 ft-lb or 61 N-m. DO NOT exceed 50 ft-lb or 68 N-m.
For the 1/2x13 holes in steel plates, we recommend up to 50 ft-lb or 68 N-m. Do not exceed 70 ft-lb (94 N-m).

What is the leadtime on Fixture Plates? Do you keep them in stock?
Standard leadtime is two weeks from order. We keep stock on hand for standard fixture plate sizes but machine the plates on a just-in-time basis. Certain plates for popular machines and configurations are kept in stock. Please contact us with questions about leadtime or to inquire about rush orders.

What is the difference between the Pitbull and Tiny Vise version?
Will Mod Vises work with non-SMW fixture plates?
Mod Vises require the unique combination of having each fixture plate hole both bored for 1/2" precision pins and tapped 1/2x13". Generally speaking, the Mod Vise will not work on other brands of fixture plates.
What is the parallelism tolerance of an SMW Fixture Plate?
SMW Fixture Plates are held to parallelism of +/- 0.001" per 24" .
