MODEL : RIG250 & 350 CNC:
These high precision CNC controlled Internal grinders are used for diverse Internal Grinding wide range of components. Modular design of these machines offer solution with straight & taper bore grinding operation.
The machine bed is made of High grade Cast Iron structure which has high static and dynamic rigidity. The Structure design facilities are best for thermal and vibrational damping. The design facilities provide easy way to flow of coolant and grinding dust.
The table moves on V & flat bed with turcite guide ways. The table is driven by high precision pre-loaded ball screw directly coupled with servo motor by precision coupling. Dust proof guard is provided on X·Z axis slide to fully protect foreign dust particle.
WORK HEADSLIDE(X·Axis) :
Work head slide is made out of graded cast iron suitably ribbed for high dynamic and thermal stability. It moves on high precision oil lubricated LM guideways. The X-axis slide driven through! precision class preloaded ball screw. Ball screw is directly coupled with servo motor.
WORK HEAD :
It has a rigid universal work head. It has cartridge type spindle. Swivelling of± 10° is possible. Work head spindle runs with P-4 class antifriction precision angular contact bearings. Work head speed is variable and controlled by AC drive.
WHEEL HEAD :
A variety of belt driven I high frequency spindles are available as per specific requirement be offered with different types of HF I bell driven spindles. The electric spindles also feature CNC controlled constant peripheral speed of grinding wheel will be provide optionally.
DRESSER UNIT :
The dressing unit consists of a single point fixed dresser which is capable of profile dressing as well as straight dressing. The dressing unit is also equipped with diamond rollerforcontinuous and reduced dressing wear.
CONTROLLER SPECIFICATION :
Fanuc Oi-TF grinding controller with auto refreshing, pitch error & backless compensation, G code & M code compatibility, electronic hand wheel.
