WOODMAN (BOX TYPE BASE) KNIFE GRINDER

This is designed to offer multiple functions: grinding cycle/rough grinding/finish grinding.


Grinding applications:
+ Straight knives
+ Linear guideways
+ General surface grinding
* Once grinding is finished, the machine automatically shuts down and then returns to its start position.

Massive machine base:
+ the machine base is fabricated by heavy gauge steel plate to achieve superior stability, and stress relieved to remain deformation free year after year. 
+ The box type base provides a solid support for the entire machine.

Downfeed control of grinding head:
+ The grinding head downfeed is driven by a servomotor which is directly coupled to a ball screw, providing high positioning accuracy and low backlash.

Rigid grinding head carriage:
+ The grinding head carriage moves on bearings for smooth movement.
+ The extra wide carriage construction in combination with great span between bearings ensures extremely uniform load distribution and increased rigidity and stability.

Coolant system:
+ The coolant is pumped by a coolant pump that discharges coolant to the point of contact between the grinding wheel and the knife. This permits a heavier cut for the grinding wheel without injurious overheat of the cutting edge of the knife and thereby shortens the time required to grind.
+ The coolant tank is equipped with filter for reclamation of the used coolant.

High precision slideways:
+ The longitudinal feed slideways employ Germany-imported guideways featuring and maximum wear-resistance.
+ The slideways are pretensioned for minimum deformation.

Manual pulse generator (MPG):
+ MPG allows for job control of vertical and longitudinal movement and added convenience of setup.

Touch screen for operational convenience:
+ LCD screen is mounted on the head carriage for easy access.

Magnetic table:
+ This machine is equipped with a magnetic table for fast knife clamping and unclamping.
+ Each magnetic table measures 150mm wide.
+ Magnetic table can be tilted and tilting degree is displayed on a digital readout.

Stable grinding head:
+ The grinding head is driven by a 15HP motor.
+ High precision wheel spindle is dynamically balanced for smooth running.

Longitudinal feed of head carriag:
+ Longitudinal feed of head carriage is driven by a servomotor and transmitted through a rack/pinion mechanism for extremely smooth movement.
+ Grinding length can be varied by adjusting the position of length stops.
