Manual operation model
All castings are tempered and stress relieved twice to assure stability of the machine structure and resist deflection under load
Hardened and ground column ways with cast spindle slide is precision fit for no "hang-up" gravity downfeed
3 HP V3 Grade spindle motor for powerful output to achieve precision
work standards and better grinding capability
Cartridge spindle with four preloaded class 7 P4 bearings and run-out
of taper nose better than 0.000060 T.I.R. provides quiet, vibration free
operation for better workpieces accuracy
The table traverses on linear ball bearings with hardened and ground guide ways to ensure a smooth and easy movement of the table
Double V cross ways are hand scraped and Turcite coated for greater flatness and high wear resistance
Indexable table handwheel for ease of operation
