Description:

HLC-100 Centreless Grinding Machine:

Machine Bed

  • The machine bed is of one piece, close grained cast iron.
  • Box structure design, heavily reinforced with ribs, provides high rigidity and stability.


Grinding Wheel Head

  • Grinding wheel head of sturdy design is fixed to the machine bed.
  • Wheel head spindle is made of special alloy steel, specially heat treated, ground and lapped to achieve high dimensional stability and long life.
  • Spindle runs in precision White Metal Bush Bearing, which give very high accuracy and excellent surface finish to the work piece.


Regulating Wheel Head

  • Regulating wheel head is mounted on double slide and swivel plate arrangement.
  • Spindle specially heat treated, ground and lapped runs in oil immersed precision Anti Friction bearings to give high accuracy and true running.
  • D.C. Thyristor drive (Optional: A.C.variable drive) provided to get infinitely variable speed of regulating wheel / work piece. Optimum RPM of work piece can be set to achieve high production and good accuracy.
  • Regulating wheel head can be tilted in vertical plane to facilitate through feed grinding.


Infeed System

  • In-feed is imparted to the Regulating wheel slide through a hardened and ground feed screw, which ensures high positioning accuracy and repeatability.
  • Specially designed nut having backlash adjustment is provided.
  • The upper slide moves the regulating wheel in relation to the work rest for easy job set up and lower (feed) slide is used for feeding work to the grinding wheel.
  • Work rest base is firmly screwed to the lower (feed) slide. Work blades can be adjusted in height on work base for different size of components.


Taper Correction

  • Regulating wheel can be swivelled in horizontal plane by the swivel plate, for fast and accurate taper correction and taper grinding.


Automatic Plunge Grinding Cycle (Optional)

  • Single lever operated Automatic Plunge grinding cycle.
  • Cycle operates as Rapid approach-Auto feed-Spark off-Rapid retraction and infeed slide moves to starting position.
  • Amount of infeed, infeed rate and spark off time are adjustable.


Dressing Unit

  • Separate hydraulic dressing units with infinitely variable dressing speeds provided for both Grinding and Regulating wheel.
  • Profile dressing of Grinding and Regulating wheel is possible with special attachment.


Hydraulic / Electrical Unit

  • Hydraulic power pack unit housed outside the machine for easy maintenance.
  • All electricals mounted in a concise panel box. Centralized controls for operator’s convenience.


Lubrication

  • Centralised lubrication system provided for efficient and positive lubrication of moving parts.


Optional

  • Form dressing arrangement.
  • Auto loading system.
  • Hydraulic ejector.
  • Bar feeding arrangement.


Range of Other Machines

  • CNC Cylindrical Grinding Machine.
  • Centreless Grinding Machine.
  • Internal Bore/Track Grinding Machine (Hydraulic/CNC).
