Key Technical Highlights

  • Micron-Level Feed Precision: Micro-feed handwheel gradations of 0.002 mm for precise depth of cut control.
  • Hydrostatic & Turcite-B Guideways: Turcite-B lined ways eliminate stick-slip motion and provide smooth table movement.
  • Spindle Runout: Guaranteed spindle taper runout within 0.001 mm for mirror surface finishes.

FAQ'S Of Technical Specifications

1. What is the vertical micro-feed division on Prayosha surface grinding machines? +Our precision surface grinders are equipped with micro-feed handwheels calibrated down to 0.002 mm (2 microns) per division, enabling sub-micron depth of cut control for fine finishing operations.
2. What table working sizes are available across Prayosha hydraulic surface grinder models? +We offer standard table sizes ranging from 200 × 450 mm (PREMIER model), 250 × 500 mm (SUPREME model), 300 × 600 mm (JUMBO model), up to 400 × 800 mm (JUMBO PLUS model), along with custom double column gantry capacities.
3. What spindle motor rating and wheel speed do these surface grinders operate at? +Depending on table size, spindle motors range from 2 HP (2800 RPM) on PREMIER models to 3 HP / 5 HP / 7.5 HP (1440 RPM) on JUMBO and JUMBO PLUS models to deliver optimal peripheral wheel speeds.
4. How does the automatic lubrication system function on Prayosha surface grinders? +An integrated centralized automatic lubrication pump continuously delivers oil to the V-and-flat guideways and lead screws during operation, eliminating stick-slip friction and reducing slide wear.
5. Are Digital Readout (DRO) systems compatible with Prayosha surface grinding machines? +Yes, 2-axis and 3-axis Digital Readout (DRO) systems with high-accuracy optical linear glass scales (0.001 mm resolution) can be factory-fitted or retrofitted to monitor longitudinal, cross, and vertical positioning.
6. What hydraulic pump power and oil reservoir capacity are required? +Hydraulic power packs use 1 HP to 2 HP motors operating at 1440 RPM, coupled with a 50-liter to 100-liter oil tank equipped with oil level indicators, suction strainers, and pressure relief valves.
7. What is the guaranteed spindle runout and surface finish accuracy? +Every cartridge spindle is dynamically balanced to ensure taper runout within 0.001 mm (1 micron), consistently producing mirror surface finishes down to Ra 0.2 microns.
8. What electrical supply and foundation requirements are needed for installation? +Our machines require a 415V, 3-phase, 50Hz AC power supply. They should be placed on a reinforced concrete foundation and leveled using adjustable vibration damping levelling pads.
