Surface Grinding Machine

Precision surface grinder for achieving high-flatness tolerances on industrial dies, plates, and machine slides.

Precision surface grinder for achieving high-flatness tolerances on industrial dies, plates, and machine slides

Typical Applications

  • Precision finishing of flat surfaces on dies, fixtures, gauge plates, and machine bases.

  • Power and cement plant maintenance, including grinding of bearing plates, liners, wear plates, and housings.

  • Steel plant toolrooms for reconditioning flat tools, shear blades, and precision plates.

  • Defence workshops for accurate surface finishing of armour plates, tooling components, and precision assemblies.

  • Surface grinding is typically used as a final finishing or corrective operation after machining, where flatness, parallelism, and surface finish are critical.

Machine Description

  • • Surface grinding machines are designed for precision finishing of flat surfaces where milling cannot reliably achieve the required flatness or surface finish.
  • • Commonly deployed in toolrooms and production workshops as accuracy-defining assets rather than high material-removal machines.
  • • Rigid machine structure manufactured from high-grade, stress-relieved grey cast iron conforming to IS:210, ensuring long-term dimensional stability.
  • • Box-type column design providing high rigidity and effective vibration damping during grinding operations.
  • • Hardened and ground alloy steel spindle supported on matched bearing pairs, grease-packed for life, suitable for sustained grinding duty with stable thermal behaviour.
  • • Electro-mechanical table movements enabling smooth and controlled longitudinal and cross travel.
  • • Guideways lined with Turcite-B to reduce friction, prevent stick-slip, and minimise long-term wear.
  • • Electromagnetic chuck with electronic controller for quick clamping, demagnetising, and safe job release directly on the machine.

  • • Perpendicularity between axes: 0.005 mm / 250 mm

Accessories & Options

  • • 2-Axis Digital Read Out (Linear Scales).
  • • Magnetic separator for coolant system & paper band filter.
  • • Sine vice, sine table, radius and angular dressing attachments.
  • • Motorised dust extraction system (for dry grinding).
  • • 1-Axis Numeric Control: Auto down-feed on Z-axis with servo drive and HMI.
  • • 2-Axis Numeric Control: Servo-controlled Y and Z axes with HMI for repetitive cycles.

Configuration Notes

  • 1. Surface grinding machines are precision finishing assets, typically selected based on required flatness, surface finish, component size, weight, and workshop cleanliness.
  • 2. They are not substitutes for milling or heavy stock-removal machines, but complementary tools in a complete mechanical workshop.
