MITSUI HI-TECH - PRECISION SURFACE GRINDERS - HMD SERIES (FULLY AUTOMATIC) - MSG-200/250/300/400HMD
- CONSTRUCTION
Extremely heavy meehanite castings, internal rib reinforced. Their meehanite casting base uses jack bolts and plates for a 5 point leveling system. Another feature, which is a trademark with the Mitsui Design, is the ease in removal and replacement of key components, providing for "No Hassle" maintenance which translates to minimum down time and cost.
- PRECISION
Not all surface grinder manufacturers can attest to precision the way they do. Their cartridge spindle is second to none and REMOVABLE. The carriage/saddle moving on (2) 45 "Vees" combined with the table moving on Linear Ball Bearings make for the repeatability for which MITSUI is known. NO design compromises here.
- DURABILITY
Precision by design means little if it can not be maintained. MITSUI provides the durability for this with D-2 hardened and ground steel ways on the table, Carriage/Saddle and even on the column for vertical movement. The linear ball bearings complement the table/carriage union with durability. The cartridge spindle's lubrication is sealed in for life and the dust sealed out. The Standard Automatic Lubricating System leaves you 1 less task to worry about, as it lubricates ALL vital components automatically to insure minimal wear and friction.
