BRIEF DESCRIPTION

  • PINNACLE-make GSH series machines are Hydraulic Semi Auto High Precision Horizontal Spindle Reciprocating Table Surface Grinding machines established on Latest European concept of Column moving design.

  • Longitudinal Axis i.e. X-Axis is driven by Hydraulic cylinder with END CUSHIONING device for good damping effects at the end of each Stroke & with solenoid valves for soft table reversals.

  • Vertical Axis i.e. Y-Axis is driven by A. C. Induction Motor through Precision Trapezoidal Lead Screw & Nut with Least Count of 0.002 mm.

  • Cross (Traverse) Axis i.e. Z-Axis is driven by A. C. Induction motor & Drive through Precision Trapezoidal Lead Screw & Nut.

  • Grinding Spindle-Cartridge is assembled with Imported SUPER PRECISION BEARINGS grease packed with Imported Grease filled for Life for long trouble-free service.

  • GSH series provides Automation in 2 Axes i.e., X-Axis and Z-Axis with Rapid Positioning & Manual Depth of cut in Vertical (Y-Axis).

  • GSH series machines are mostly used for Toolroom purpose.
