Product Description
 HOACCU M7020 is a kind of  Large High Precision CNC Surface Grinder or surface Grinding machine 
1) Heavy duty construction, together with lifetime accuracy. The structural parts are manufacturered from high quality Meehanite cast iron, rib reinforced for maximum rigidity and vibration dampening. X-, Y- axis slideways are coated with Turcite B and precision scraped for smooth movement and high accuracy.

2) 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 & high accuracy.

3) Direct spindle drive from high precision “V-3” motor, better tolerance and lubrication with result in longer service life. No fray or noise, no vibration on spindle or motor.

4) Leadscrews are hardened by “electroless – nicklide” process yielding a controlled uniform 50RC surface hardness. Precision grinding of the vertical and cross feed screws built-in tight but fluid motion control over the slides needed to maximize surface grinding positioning and accuracy.
