Precision grinding on spindle housing ensures the accuracy of the quill travel within 0.0005" per 5".

Every spindle is aligned and measured before final grinding. The high speed internal grinder is able to grind the spindle taper within 0.0008” of each other. This enables us to swap spindles to other machines and still keep the spindle run-out within 0.00015”.

The cylindrical accuracy of the quill is within 0.0002”, and the bearing seat accuracy is within 0.00005”. This keeps the quill travel accuracy to within 0.0005”, and spindle run-out within 0.00015”. This prolongs the life of the spindle when operated properly.
