Feature
Machine design
435mm（17.12“）wide column design: Comparing with other manufacturer, it provides better stability and rigidity.
Wheel spindle air blowing design
Wheel spindle air blowing design could create positive pressure. It effectively prevents dust going into the spindle, and maintains the internal coolant of the spindle. The catrige spindle itself has a outer spiral groove design, and it could effectively prevents the spindle from thermal raising.
15HP spindle motor
Heavy duty spindle with 15HP spindle motor allows the machine to grind hard material or to grind with creep feeding operation
Machine design
774mm wide machine base design provides excellent machine rigidity, and low dynamic grinding operation
X Axis Working table guideway double V design
X Asis guideway is precisely hand scraped, oil firm lubrication supplied, and Turcite-B coated to ensure positioning accuracy and long term usage.
Rigid rib-box structure
Rigid rib-box structure is consist with the same material level of Meehanite base casting, ensuring the machine rigidity and stability.Machine net weight: 2,200kg.
