Hydraulic Cylindrical Grinding Machine Manufacturer

Prayosha Enterprise manufactures state-of-the-art Hydraulic Cylindrical Grinding Machines designed for precision external (OD) and internal (ID) grinding of cylindrical components.

Built with high-rigidity heavy castings and precision cartridge spindles, our cylindrical grinders achieve sub-micron roundness (within 0.001 mm) and mirror surface finishes on shafts, rolls, and spindles.

The infinitely variable hydraulic table traverse and AC variable frequency workhead drive provide smooth, shockless strokes and optimal RPM selection for varying workpiece diameters.

Equipped with a swing-down internal grinding attachment, operators can seamlessly transition between external and internal grinding setups without disturbing workpiece alignment.

Trusted by leading automotive, hydraulic cylinder, and toolroom manufacturers, our hydraulic cylindrical grinders deliver long service life and reliable heavy stock removal.

Advantages of Hydraulic Cylindrical Grinding Machine

  • High Concentricity & Roundness: Delivers roundness within 0.001 mm on shafts, spindles, rolls, and armatures.
  • Combined OD & ID Grinding: Swing-down internal grinding attachment enables external and internal grinding in a single setup.
  • Infinitely Variable Workhead Speed: AC variable frequency drive allows smooth RPM selection for various shaft diameters.
  • Hydraulic Table Traverse: Smooth, shockless table stroke with adjustable dwell time ensures uniform end-to-end shaft diameter.
  • Rigid Tailstock & Headstock Support: Heavy-duty morse taper centers maintain rigid alignment under heavy grinding pressure.

FAQ'S Of Hydraulic Cylindrical Grinding Machine

1. What is a Hydraulic Cylindrical Grinding Machine? +A Hydraulic Cylindrical Grinding Machine is designed to grind the external (OD) and internal (ID) cylindrical surfaces and tapers of rotating components with high concentricity.
2. What components are typically ground on a hydraulic cylindrical grinder? +Common parts include engine shafts, electric motor armatures, hydraulic piston rods, rolls, bushings, pins, and spindle shafts.
3. How does hydraulic table traverse work on cylindrical grinders? +The hydraulic unit drives the table back and forth smoothly along the longitudinal axis with adjustable dwell times at table reversal points for even end-to-end grinding.
4. Can both external and internal grinding be done on this machine? +Yes, with an optional internal grinding attachment (ID swing-down spindle), the machine can perform both OD and ID grinding operations efficiently.
5. What accuracy and roundness can be achieved on a hydraulic cylindrical grinder? +High-precision models can achieve roundness within 0.001 mm to 0.002 mm and surface finishes down to Ra 0.1 microns.
6. How do you maintain a hydraulic cylindrical grinding machine? +Keep tailstock and workhead centers clean and lubricated, check drive belt tension, inspect hydraulic fluid cleanliness, and balance grinding wheels regularly.
