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.

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.

Precision clamping fixture PL-G with threaded spindle
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.
Calculation: x = 0.4107 • 100 = 41.07.
The height of the gauge block 41.07 mm.
