Precision Clamping Fixtures 665

Precision clamping fixture PL-S

Design: Body and jaws made of alloy tool steel, hardened and precision ground. The stationary jaw is smooth, whilst the mobile jaw comes with a horizontally and vertically ground V-block and quick adjustment. Clamping and releasing through Allen key. With quick adjustment and draw-down effect. Jaw adjustable in steps, locks into place automatically. Side clamping surfaces for clamping jaws. No spindle which could e.g. foul during the erosion process. Supplied in wooden case, without Allen key. Angularity 1 : 100 mm = 0.005 mm Parallelism 2 : 100 mm = 0.002 mm Application: Predominantly for use in tool making on grinding, milling and engraving machines, on jig drills, for measuring and inspection work, and for manufacturing processes requiring the most utmost clamping precision. Note: Allen key is found on Ç 5/123.

Precision sine wave vice PS-SV with front rotating shaft

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. Supplied in wooden case. Angularity: 100 mm = 0.005 mm, Parallelism: 100 mm = 0.002 mm, Angular deviation at 45° ±15" . Application: For high working accuracy in tool-making when grinding, milling, measuring, etc.

Example: Wanted: Gauge block for angle adjustment of 24° 15' on the Precision sine bar machine vice PS-SV. Given: K = 100, sin α = 0.4107.

Formula for calculating the gauge block x x = sin α • K

(for support surface A) (for support surface B)

x = sin α •

K + 1

Calculation: x = 0.4107 • 100 = 41.07. The height of the gauge block 41.07 mm.
