Product Description
M1432C
Universal Cylindrical Grinding Machine
 
Max. Grinding Diameter: Φ 320mm
Max. Grinding Length: 1000mm/1500mm
 
.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 machining of small-lot shafts and sleeve parts in the machining workshop, tool workshop,overhaul workshop, etc.

Operation mode
 Manual operation: longitudinal grinding, plunge-cutting grinding.
 
. Features of Structure and Performance
  • The wheel head spindle uses our own technology, with the characteristics of high rotation precision, good rigidity, and high grinding quality. The spindle materials 30CrMOALA have gone through nitrogen treatment, and the hardness of the spindle is up to HV900, making the working life long and precision retention high.
  • The work head spindle adopts our own technology, with the characteristics of high precision and good rigidity. And the surface roundness of internal and external cylindrical parts fixed on the chuck is apparently higher than the requirements of the national standards.
  •  The feeding guideway adopts plastic-coated guideway, improving the stability and vibration resistance of low-speed running.
  •  With the screw pump adopted in the hydraulic drive system, it gains the features of smooth running and low running noises.
  •  For the operation system, a single operation handle is integrated in the operation box and the electric controlling buttons are centralized, making the operations easy and reliable.
