Precision vises hold work to tolerances that ordinary vises cannot. This guide covers cross-slide, milling and machine vises for CNC and manual machining.
1Parallelism is the Point
Precision vises are ground so jaws sit parallel to the table within 0.001″ (0.025mm). That baseline determines repeatability of every part you machine.
2Cross-Slide Vises
Add X-Y positioning without moving the workpiece — useful for precise hole patterns and second-op milling operations on a manual mill.
3Milling and Machine Vises
Kurt-style bodies with double-locking mechanisms hold work without lift, even on high-speed CNC cuts. Sizes are matched to table slot spacing, not jaw width alone.
4Custom Jaws
Soft aluminum, V-groove and contoured jaws protect finished surfaces and cradle irregular parts — a common OEM customization for production shops.
FAQ
Quick Answers
What accuracy does a precision vise provide?+
Precision-ground jaws deliver 0.001″ (0.025mm) parallelism to the table, verified by coordinate measuring machines before shipment.
Can precision vises be made for my CNC table?+
Yes — manufacturers match T-slot dimensions, bolt patterns and jaw profiles to your specific machine and workpieces.
