Universal tool-grinding machines give an opportunity to carry out high-quality sharpening and a repoint of the tool from steel tool, hard-alloy metal and a mineral ceramics. Use of similar devices on production allows to reduce the general expenses, to increase the outputs and to increase quality of production.

For sharpening and operational development of tools of main types including the it is a lot of front, our enterprise offers tool-grinding the VZ-818 machine which can be used on tool production and in other spheres of the industry connected with metal working. Besides sharpening, the device allows to make flat grinding, and also internal and external circular grinding.

The machine is executed on the basis of a welded bed of a box-shaped form with guides and balsas for fastening of the basis of a table. Movement of a table in the longitudinal direction is made in the manual way. Movement of the grinding grandma in the cross and vertical direction is made manually, and the adjusting vertical shift of a head is mechanized.

Main advantages of the VZ-818 machine:
  • great opportunities with a small weight and dimensions;
  • the drive of a table is carried out by a flywheel with gearing;
  • the engine of a circle is turned in the party opposite to a spindle that allows to lower time of read-justment of the machine and expands his technological capabilities;
  • existence of steel roller guides gives the chance to establish on a table heavy details and devices with preservation of accuracy of movement.

Possibilities of the device can be expanded considerably with the help of more than 38 types of extras.
