Major cast parts are made of stress relieved and annealed Meehanite castings to ensure stability, rigidity, high accuracy, and extended working life.
Precision steel balls produce extremely smooth operation and long working life of slide ways. (B series)
The spindle is coupled directly with a V-3 motor which ensures a high spindle run out accuracy of 0.002mm. The precision cartridge spindle is greased and requires very little maintenance, and incorporates 4 preloaded class 7(P4) super precision angular contact ball bearings for heavy grinding.
Lead screws: Heat treated and ground, smooth operation and extended working life.
Double V slideways are precisely hand-scraped and coated with Turcite B for smooth movement and extra stability.
Standard auto-lube system provides ample lubrication on all slideways, lead screws and nuts. Lubricating oil is filtered and recycled for smooth movement and minimal wear and tear.
