*Spindle motor is driven by high torque timing belt with spindle, ensures no slip, low noise and low vibration
*P4 angluar contact spindle bearing (2 front and 2 rear) reduces temperature variations
even at high speed cutting after long performance.
*Rigid meehanite casting main frame is annealed and stress relieved
*32mm C3 double nut precision ball screws, pre-loaded to control backlash & pre-tensioned to minimize temperature variation.
*Telescopic steel XYZ way covers protect ways and ball screws from dust and coolant fluid.
*High pressure water 4 jets for chip removal
*High grade of Turcite-B fitted to X/Y/Z hardened & ground slide ways & gibs to achieve greater wear resistance.
*Fully enclosed guarding including 3 pcs. Chip Augers provides a safe and clean working environment
*Carousel type 12 or 16 tools bi-directional ATC, reduces tool changing time in half for more process
