Sine Vises, Bars & Plates
The sine vise shown allows quick & very accurate angle setting using precision spacer blocks.
The distance between the roll centers is very accurate as are the other dimensions.
REQUIRED SPACER SIZE" = SINE (DESIRED ANGLE°) x DISTANCE BETWEEN ROLLERS"
RESULTANT ANGLE° = ARCSINE (SPACER SIZE" / DISTANCE BETWEEN ROLLERS")
For example, if you want to set a 30º angle & the distance between the rolls is 5.000", calculate the sine of 30º & multiply by 5.0000". The size of the spacer is exactly 2.5000" (note the calculator must be in degrees). Sine bars are used in the same manner. For a given length sine bar & spacer block size you can also calculate the resultant angle.
This calculation is analogous to that for tapers.
2-in & 3-in wide sine vises; both
are 4" between rolls.
