Headstock, Body, Saddle,
Base and Work Table all use superior grade of cast iron.
All are stress relived to ensure maximum accuracy and
absolute rigidity.
Spindle Headstock Design utilizes box shape design,
internally ribbed reinforcement, for highest rigidity,.
maximum stability, ideal for heavy-duty machining.
Maintaining constant spindle
temperature, by circulating cooling oil thru a highly
efficient spindle chiller unit, to ensure working accuracy.
Linear Guideways are used on all three axes due to their
high rigidity, low noise. and low friction. These features
helped to achieve high- speed rapid movement and excellent
circular accuracy.
Double nut C3 class precision ballscrews are used on
all three axes. Along with pre-tensioned and supports
to minimize backlash and to compensate for error caused
by temperature differences in order to maintain positioning
accuracy.
Laser calibration is performed and certified by PMC.
The testing standard VDI 3441 3σ is performed 6 times
on each axis full length of travel. Each machine is
certified by PMC for its accuracy.
Renishaw circular ball bar test is done on every machine
to check for roundness and geometric accuracy. Servo
movement accuracy is maintained with this test.
Two Guide Way base along with wide stance column design
greatly increasy contact surface between Column and
Machine Base, which reinforce greater head supports.
Column is heavily ribbed with cell shaped structure
internally to minimize twisting deformation during machining.
High
Speed Direct-type Driven Spindle
1. Wide stance design with precision angular spindle
Bearings. Design specially for high speed and high
precision.
2. 10,000/12,000/15,000 RPM Direct driven spindle
produce low noise, low vibration, and excellent surface
finish.
