Product Brief

Manufactured from selected tool steel, these Solid Sine Vices are fully hardened (55-60 HRC) and tempered, mounted onto a precision hinged bottom plate. All the surfaces of the vice are precisely ground for extreme accuracy

These are very useful for manufacturing processes that require the highest standards of clamping accuracy at desired angles

A minute angle step of 0.2"/5 mm allows very small angles to be set with ease using standard gauge blocks

These are available in two models:

Screw Type
Screwiess Type

Sine Vice being used to drill an angled hole
on a machine wheel
Using Gauge Blocks:
1. Pivot the Sine Vice upwards.
2. Insert gauge block between surface A & the headed dowel
3. Turn back screw so that Sine Vice is pressed against the gauge block & locked positively
4. When adjusting very small angles, place appropriate gauge blocks on surface B which is lower than A by 5mm/0.2"
Determining the height (h) of the Gauge Block to be used

h = sin a × D for surface A

h = sin a × D + 5 mm / 0.2" for surface B

eg: To determine height of gauge block for angle adjustment of 10°, given D =150 mm:

h = Sin 10° × 150 = 26.04 mm

Thus for setting on angle of 10°, a gauge block of height 26.04 mm is required
