The Allis Tool CNC Grinding Machines. We are equipped with multiple surface grinding machines that can accommodate large parts with flat surfaces in sizes of up to 24 x 60 x 20 inches and can grind surfaces to tight tolerances of about 0.00005 inch. Custom programming heavy duty CNC tooling allows for silly precise cuts that would be impossible otherwise.
grinding tolerances Flatness tolerances are met by shimming the work piece, flipping the work piece, and sparking out until tolerances are met. Common parallelism tolerances for Blanchard grinding range from within .003" to within .010", often times depending upon the size of the part.
Holding tolerances on diameter size and cylindricity to the sub-micron level – with Ultra-Precision Centerless Grinding we work closely with engineers who require a much higher level of precision for many of their high-tech parts. We use only new CNC grinding equipment because today's tolerances require today's technology.
Grinding ratio is being decreased. Increase the speed. Reduce stock removal. Decrease the infeed rate and traverse feed rate. Increase dresser's setting angle. Decrease the dressing amount and traverse feed rate. Workpiece is burnt. Reduce the amount of stock removed per pass. Use a coarser dressing, more 'open'.
