SINE BLOCKS
NO. 9118 SERIES
Taft-Peirce Sine Blocks have been favorites with toolmakers for many years. They are heavy-duty fixtures for holding work that must be set to precise angles for layout, light machining, or inspection. Each block is equipped with a precision ground end plate that acts as a work-positioning stop, and tapped holes in the top surface and sides are provided to allow a wide variety of work-clamping set-ups.
SPECIFICATIONS
Taft-Peirce Sine Blocks are made of high quality alloy steel, scientifically heat treated for maximum stability and wear resistance. The top working surface is precision ground flat and square with the adjacent sides and parallel to the sine rolls. The tool steel sine rolls are ground and lapped alike for diameter, roundness, and straightness, and are mounted parallel to each other at their nominal center distance within the limits specified below. All Sine Blocks are shipped packed in finished wood cases with hinged covers.
