MACHINE DESCRIPTION

 

Machine Bed. Sturdy welded construction, thermally stress-relieved, vibration-absorbing, torsion-resistant box design. Smooth interior with coolant outlet on the side for quick discharge of coolant and easy cleaning of the machine bed.

 

Rails. The rails are precision ground and specially hardened. Replaceable railway strips are fitted for easy maintenance.

 

Knife Bed. The basic model features a clamp type knife bed. The High-end model features an electro-magnetic knife bed. Both the clamp type knife bed and the electro-magnetic knife bed swivel 0 - ± 90°, lockable at any angle.

The electro-magnetic knife bed is a solid billet of steel with the electro-magnetic plate precision-mounted and sealed to its top surface. The grinding carriage control panel includes a switch to de-magnetize the electro-magnetic knife bed for quick-release of knives.

 

Grinding Carriage. The grinding carriage is manufactured from vibration-absorbing solid cast iron components. For easy and safe observation of the grinding process, large openings are provided on either side of the grinding motor support unit. The grinding carriage unit traverses along the machine bed rails on special high-precision rollers.

 

Down Feed. The down feed system features a variable feed rate and guarantees accurate positioning during the feed cycle.

 

Grinding Motor. The Accura GrindMaster grinding motor has a unique vibration-free design, equipped with extra-large high precision grade bearings, and dynamically-balanced rotating parts. The grinding motor is completely sealed against coolant and grinding debris. The grinding motor can be easily tilted for either angled or flat grinding. The main spindle of the grinding motor is hollow to enable coolant supply to be directed to the grinding area. For high-end models, an optional AC frequency inverter drive allows variable speed up to 1450 RPM.

 

Grinding Wheel. Cylindrical type, flange-mounted.

 

Traverse Drive. An optional AC frequency inverter drive powers a motor to drive a  chain & sprocket gear system to provide the traversing motion of the grinding carriage. Movable stops and proximity switches control the grinding length; the stops easily slide along a rail to increase or decrease the grinding length.

 

Coolant Equipment. The coolant supply system is a multi-chamber coolant tank and supply pump at the end of the machine bed. The pump supplies coolant to the grinding area through the grinding motor spindle controlled by flow taps.      

A complete coolant system with a separate pump and filter keeps knives lubricated, cool and burn-free even during prolonged and aggressive grinding procedures.

 

Electrical Equipment. 220/380/415/440V 50/60Hz 3 Phase. All electrical components are placed in a separate control cabinet. The control and instrumentation panel are mounted on the grinding carriage. The cables for the grinding carriage run through an articulated cable rack at the rear of the machine.
