Description

Precision sine wave vice PS-SV with front rotating shank Design: Body and jaws made of alloy tool steel, hardened and precision ground. The stationary jaw is smooth, the mobile jaw comes with a horizontally ground V-block. Clamping and releasing through threaded spindle. Angle adjustment with a setting range of 0-46° is performed using gauge blocks according to the sinus principle; bearing pins and headed dowels are hardened and ground to an accuracy of 0.001 mm. The clamping device can be positively locked in every angular position. Perpendicularity: 100 mm = 0.005 mm Parallelism: 100 mm = 0.002 mm Angular deviation: at 45° ±15". Formula for calculating the gauge block x: x = sin alpha • K (for support surface A) x = sin alpha •K + 1 (for support surface B) Example: Wanted: Gauge block for angle adjustment of 24° 15´ on the precision sine clamp PS-SV. Given: K = 100, sin alpha = 0.4107. Calculation: x = 0.4107 •100 = 41.07. The height of the gauge block 41.07 mm. Application: For high working accuracy in tool-making when grinding, milling, measuring, etc.
