Sine Angle Plates save time and trouble in setting work to simple or compound angles for light machining and inspection. Top plates are equipped with end stops for positioning work and tapped holes for use in applying clamps. All locking screws are tightened by turning them toward the setting rolls. A precision ground 100" step on the base plate makes it possible to set small angles down to zero using standard gage blocks.

Sine Angle Magnetic Chucks combine the principle of Sine Angle Plate construction utilizing a Permanent Magnetic Chuck. They are available in either simple or compound angle styles. Angular settings are obtained in the same manner as with Sine Angle Plates, except that work is held by magnetic force instead of by mechanical clamping.

SPECIFICATIONS

6" x 6" Sine Angle Plates and 6-1/2" x 12" Sine Angle Plates are made of close-grained cast iron. Both sizes are scientifically heat treated for maximum stability and wear resistance. All Taft-Peirce Sine Angle Plates and Sine Angle Magnetic Chucks are precision ground on working surfaces and feature tool steel sine rolls, that are hardened and lapped. Specific dimensions and tolerances are listed in the tables below.
