PHR 500C TO 1500C Series Catalogue
- PHR CNC series machine models are CNC-Controlled Fully Automatic High Precision Horizontal Spindle Rotary Table Surface grinding machines.
- PHR CNC series machines are suitable for grinding High precision thin & circular parts. In case where High Production of parts are required with high quality, precision & good surface finish in much lesser time, these machines are the perfect alternate to Horizontal Spindle Reciprocating table Surface grinding machines.
- Rotary Movement i.e. X-Axis is Hydrodynamically lubricated table with heavy load capacity, neglecting the wear & tear of guide ways and inaccuracy caused by rotary wobble.
- Vertical Movement i.e. Y-Axis is driven through Ball Screw with Nut & A.C. Servo motor.
- Cross Movement i.e. Z-Axis is driven through Ball Screw with Nut & A.C. Servo Motor.
- Grinding Spindle-Cartridge is assembled with Imported SUPER PRECISION BEARINGS grease packed with Imported Grease filled for Life for long trouble-free service.
- PHR CNC machines is equipped with Auto parallel Dressing & Auto compensation.
- All the data for grinding & dressing is settable in a 7-inch Programmable Colour Machine Operating Panel (MOP).
- PHR CNC series machines are mostly used for High Production purposes with good accuracy & surface finish.
- PHR CNC series machines are used in various applications in Wood working machinery parts, Gear manufacturing, Automobile, Bearing & Pumps-Valves Industries.
