HIGH RIGID CASTING CONSTRUCTION
Heavily ribbed all Meehanite processed fine grey cast iron, base, table, saddle and column insures maximum rigidity and vibration dampening for outstanding performance over the life of the grinder. X and Y slide ways are coated with "TURCITE-B" and precisely hand scraped allowing smooth movement & hight accuracy.

PRECISION GRINDING SPINDLE
Direct spindle drive from high precision "V-3" motor, better tolerance and lubrication will result in longer service life. no fray or noise, no vibration on spindle or motor.

PRECISION LEADSCREWS
Leadscrews are hardened by "Electroless-Nicklide" process yielding a controlled uniform 50Rc surface hardness. Precision grinding of the vertical and cross feed screws builds in tight but fluid motion control over the slides needed to maximize surface grinding positioning and accuracy.

RIGOROUS ACCURACY INSPECTION
Each machine is subject to rigorous accuracy inspection to ensure an accurate machining result.
