Uncover premium suppliers and manufacturers of double-column surface grinders within China who deliver outstanding surface grinders machines that are capable of handling the most demanding of operations. These machines have robust and rigid designs along with highly advanced and powerful CNC controls, spindles ,and tools, which are cost-effective.
The machine in this series has a gantry configuration and consists of a double column and a beam, along with a bed. This forms a closed, highly rigid frame that has high accuracy.
It is an NC servo-controlled fixed beam gantry rail grinder and is a fusion of modern machine with electric machining and hydraulic technologies.
The advantages of a hydrostatic bearing with high motion accuracy are no wear and tear, a long life span, a small starting power, high resistance against vibration even at high speeds, and good bearing capacity.
Longitudinal motion is programmed at hydraulic variable speeds.
The MKW series also has an added advantage of having a CNC system integration, which expands its capabilities to a 2-axis CNC machine.

Maintaining a liquid layer in a bearing system results in accuracy of motion and a near total absence of friction, effectively eliminating wear of the bearing parts, giving the bearing a long life and low power requirement during startup, and high bearing capacity as well as high speed resistance to vibrations.
The longitudinal moves in variable speeds, it moves uniformly with the aid of a motor.

The entire system adopts a gantry type layout composed of double columns, beam and bed body.
The beam is rigid with good mechanical properties as it has a ladder structure and partially attached steel guide rails with a roller block.
The dynamic and static shaft tiled spindle of the grinding head has high longevity, movement precision and good anti-vibration performance.
The working table which is advanced is driven by an oil cylinder with low noise and stable movement, which is step-less speed controlled.
