PRECISION CENTERLESS GRINDER             Price List

FEATURES :

  • MACHINE STRUCTURE
    The base of the machine is made of high grade cast iron which ensures machine life and rigidity.

  • SLIDE WAYS 
    The sideways of regulating wheel are casted of double reverse V type and precisely hand scraped & coated with Turcite B, allowing a smooth movement & longevity.

  • GRINDING & REGULATING WHEEL SPINDLES
    Both of the grinding wheel and regulating wheel spindles are made of NI-CR-MO alloy steel and are sufficiently carbonized, hardened and ground to obtain high accuracy and long life. The regulating wheel is inclinable for
    5o to meet different grinding demands. The spindles are retrofitted with Hydra-static Babbitt bearings and Auto Lube System. When the spindles rotate, they automatically create oil film between the spindle and bearings to prevent any metallic contacts so as to ensure accuracy and spindle life. A pressure micro switch is fitted to detect oil pressure on the auto lube system. Spindles will not rotate under insufficient pressure in the interest of safety and machine life enabling free of maintenance.

  • AUTO LUBRICATION SYSTEM
    This unit is fitted as a standard to provide sufficient lubrications for both wheel spindles, while a one-shot lubricator is utilized for sideways, to obtain smooth movement & long life.

  • HYDRAULIC DRESSING ATTACHMENT
    The hydraulic dressing attachment is furnished as a standard for both grinding & regulating wheel, and is capable of various profile truing in conjunction of template. Dressing speed is infinitely variable and driven by hydraulic.

  • ELECTRICAL CABINET A concise electrical cabinet is equipped for convenient maintenance and service.

  • CONTROL PANEL Control panel is utilized for easy operation.
