Machine Design Feature
X, Y, and Z axes are driven by A.C. servo motor and precision ballscrews, providing high positioning accuracy and repeatability.
Spindle Air Purge design
The air purge designed spindle generates positive air pressure between the spindle and spindle housing. The spiral groove design helps keep the spindle cool and efficiently prevents small chips from entering.
5 HP Spindle Motor (EASY 820)
An optional 5 HP spindle motor is available to work with the ultra heavy duty spindle for tough material or creepfeed grinding.
Roller Type Linear Ways
Roller type linear guide ways are used in Y axis and Z axis of EASY-820 for superb rigidity and micro feed acuracy.
Machine Design
Extra wide 774mm (30.47”) machine base design, providing excellent rigidity for low vibration dynamic grinding, 435mm (17.12”) large column
Precision hand scraped longitudinal travel guideways with hydrostatic oil film technology and Turcite-B coating to assure the positioning accuracy and machine longevity.
Ultra Rigid Box Structure Design
Box-structure machine base is made of Meehanite cast-iron to guarantee the superior rigidity and stability of machine. Machine net weight : 2,200 kgs (4,840 lbs).
