Universal Cylindrical Grinding Machine

Max. Grinding Diameter:Φ 500mm
Max. Grinding Length:2000/2500/3000mm
Application of the Machine
Application .
The machine is used for the external and internal surface grinding of cylindrical and conical workpieces.
Scope of application ,.
The machine is suitable for the tool workshop, overhaul workshop and small-lot machining workshop.

Features of Structure and Performance
  • The longitudinal movement of the worktable is driven by hydraulic stepless variable speed transmission or hand-wheel transmission. It adopts forced feed lubrication and plastic-filmed guide way, which improves the machine's vibration resistance and running stability at low speed.
  •  For the wheel head, its fast forward/backward of feed is driven by hydraulic system, and rough and refined feed is controlled by hand-wheel transmission.
  •  The grinding wheel spindle is supported by high-rigidity sleeve type hydrostatic/hydrodynamic bearing, with the characteristics of high rotation precision and high rigidity.
  • The work head adopts double-speed motor and three-gear transmissions, gaining the characteristics of high transmission precision, good rigidity and easy-to-operate. The work head spindle uses sliding bearing structure and the clearance of fore bearing is adjustable to meet the needs of center or chuck grinding. And the work head can be adjustable in anti-clockwise direction for any angle within 90 degrees so as to grind internal or external conical work-pieces with chuck.
  • The machinehas the function of internal grindingand the internal grinding spindle is supported by rolling bearing. Through replacing belt pulley, four kinds of rotary speeds can be achieved in order to grind internal cylindrical work-pieces of various diameters.
  • The wheel dressers are respectively installed on worktable and tailstock, providing two kinds of dressing.
  • The machine has the following features: rational overall layout, attractive appearance, centralized and visualized operating handles, and simple and safe operation.
