Double Column Grinding Machine

Precise ! Stable ! Heavy Duty !

This and More can be Found on the TOP-ONE Grinding Machine

  • Superior surface finish
  • High flatness accuracy
  • Supreme dimensional accuracy
  • The best rigidity and stability


Massive Base

  • The base is a one-piece fabrication from high quality Meehanite cast iron, tempered to relieve internal stress for eliminating thermo deformation.
  • Two extra-long, wide and deep vee slideways on the base provide outstanding load-resisting capabilities. The double V slideway surfaces are precision scrapped in combination with forced lubrication, ensuring smooth table feed.
  • V & Flat (Standard)

    Upon customer's requirement, V and Flat slideways on the base is available.

Double V Slideways (Optional)

Rigid Table

  • The box-type table is a one-piece fabrication made from Meehanite cast iron, and tempered to relieve stress.
  • The table slideways are coated with Turcite-B for outstanding wear-resistance.
  • Extra-large span between slideways provides an increase in rigidity. In addition, the table is capable of resisting heavy loads without deformation.

X-axis Driven By Hydraulic Cylinder

  • The table feed (X-axis) is driven by a double-acting hydraulic cylinder.
  • The cylinder stroke speed can be adjusted on the control panel.
  • The hydraulic system has a buffering function, which may suppress serious impact at both ends of the cylinder stroke, This function provides a protection for the cylinder while extending its service life.

Hanged Control Box

  • The hanged control box can be moved to any position. This excellent accessibility makes it easy for the operator to check during grinding test and idling.
  • The hanged control box is equipped with a counter-balance weight to facilitate control box movement.

Table Is Self-finished By The Machine

When assembling the table on the machine, our technicians use the machine to finish the table surface. The self-finishing of the table ensures better geometric accuracy.
