The Cylindrical Grinder is suitable for grinding cylindrical and taper workpiece with surface roughness of Ra0.32µ m and roundness of 0.003mm, cylindricity of 0.008mm.

• Longitudinal movement can be effected hydraulically at sleeplessly variable speed or by hand wheel.
• Transversal movement is possessed with rapid approach and withdrawal hydraulically and micro feed manually.
• The wheel dresser is mounted on the inside of tailstock with its dressing amount adjustable by hand.
• Workpiece, wheel, oil pump and coolant pump are driven separately by individual motors.

• Model MQ1350B Cylindrical Grinder is designed for grinding cylindrical or taper surface of rotational parts. It is highly adaptable for single and small lot production.

  　

• WORKING ACCURACY:
  Roundness...................................5µ m
  Cylindricity.................................8µ m
  Surface roughness........................Ra0.32µ m

• Machine table longitudinal travel, wheel head rapid approach and withdrawal and automatic periodic cross infeed are driven hydro-electrically by push button operation. The machine also has the following functions manual mode: hand operated table traverse and wheel head cross infeed plus tailstock quill retraction by foot.
• The work head can be swiveled in counter-clockwise direction in 90 degree range. By swiveling the work head, or wheel head or table, components with different external or internal taper can be ground. By turning down the internal grinding attachment internal surface of components can be finished and six sets of grinding quills are provided for grinding selection.

  　

• WORKING ACCURACY:
  Roundness...............................3µ m
  Cylindricity.............................6µ m
  Surface roughness....................Ra0.32µ m

• Model M7475B vertical surface grinding machine is highly efficient units with circular magnetic table and vertical grinding head for plane surface grinding with end face of grinding wheel. It is widely used for rough grinding of stocks and rapid grinding to standard accuracy. When used with fine grit wheel the machine can be applied for grinding accurate and good surface finish workpieces and good surface finish workpieces such as bearing rings, piston rings etc. The following features are provided.

  　

• WORKING ACCURACY:
  Parallelism............................10µ m
  Surface roughness....................Ra1.25µ m

• Grinder model M7120D is simple and easy in operation. It enjoys wide application in metalworking industry for grinding flat and side surfaces of workpiece. It is extremely suitable for small and medium lot processing in production, tooling and jobbing shops.

  　

• WORKING ACCURACY:
  Parallelism.........................5µ m/30mm
  Surface roughness.....................Ra0.63µ m

• Model MQ8260B Crankshaft Grinder is suitable grinding the journals and pins of crankshafts, it may also serve as a cylindrical grinder.
• The table travel is effected either by power or by hand. When the table is actuated by power, it is only made inching or moving rapidly for grinding the next pin or journal. The rapid travel is effected by hydraulic means.
• The new designed left and right chucks are used,The max. adjustment in vertical is 110mm and in cross is 2.5mm. It is only to loosen a screw when indexing, the chucks can be swung at once.

  　

• Working accuracy:
  surface roughness....................Ra0.32µ m
  roundness::.............................0.01mm
  taper:.............................0.01mm
