DSG-3A820H~2460H Semi Auto Precision Surface Grinder Solutions

Features

Rigid CONSTRUCTION：The base, saddle, heavily ribbed column, table and wheel head are "MEEHANINTE" casting which are produced by our related corporation and through internal stress elimination (annealing and seasoning), which assures the highest accuracy and long life.
TURCITE-B slide way：All slide ways are coated with TURCITE-B and then hand scraped for precision operation and longevity.
SPINDLE：The V3 graded motor directly coupled to the cartridge style spindle, which is supported by P4 super precision preloaded bearing with sealed lubrication to ensure the run out within 2* and high durability.
AUTO LUBRICATION SYSTEM：The automatic lubrication system is furnished as standard to provide ample lubrication on all slide ways and leadscrews whenever the spindle is under the power, thus assuring smooth table movement.
