Frequently asked questions

QGJ 50 sine bar vise — what is the "sine bar" and what is it used for?

The sine bar is a precision cylinder with fixed and certified diameter and center distance — by placing gauge blocks under the cylinder, a mathematically precise angle of inclination of the vise is obtained: angle = arcsin(thickness / center distance). The QGJ 50 vise with jaw width ? mm mm allows working pieces with precise angles (e.g. 30°, 45°, 60°) on grinding machines and milling machines — the angle is calculated, not estimated.

How is the thickness of gauge blocks calculated for a specific angle?

Formula: thickness = sin(angle) × sine bar center distance. For angle 30° and center distance 100 mm: thickness = sin(30°) × 100 = 0.5 × 100 = 50 mm. Reference sine tables pre-calculate these values for all angles — available in ISO standards or as digital tables. The precision of the angle depends on the precision of the gauge blocks used.
