 feature
The use of different tooling and configuration can bearing the inner circle, outer circle, inner groove, outer groove, ribs and special torus for grinding, can be used for bearings, machinery, automobiles, sewing and other industries.
The grinding machine feed system adopts the "T" type structure: the workpiece axis is perpendicular to the grinding wheel shaft feeding direction; the single servo (workpiece drag plate feed) structure; the centerless grinding; the dresser feed is the lifting cylinder control.
Grinding method using manual clamping, centerless grinding method.
Mechanical standard configuration includes bed, protective cover, workpiece shaft, manual loading and unloading, wheel spindle, workpiece and grinding wheel feed system, single point linear dresser, hydraulic and lubrication system, cooling system.
Operating system: the use of touch screen parameters set, man-machine interface is good, easy to operate.
Tool structure: electromagnetic centerless fixture, the end of positioning, bearing seat adjustable axle, tungsten steel (carbide YG8) support, all supporting parts are made of non-magnetic materials.
Spindle bearings: P4 grade angular contact bearings, grease lubrication; drive motor: frequency conversion motor; workpiece box 0 ~ 60 ° adjustable. The workpiece axis: speed range: 0-2000 r / min, stepless speed control;
Grinding wheel shaft: shaft research electric spindle (P4 bearing), high strength, high stiffness, high power, 60m / s high speed grinding, oil mist lubrication. Grinding wheel shaft through the cooling water (separate water tank).
Dresser: single point diamond pen dressing, manual repair compensation; dressing for a single point of straight line dressing, lift the cylinder control dressing, by the hand wheel device control micro-feed.
Feed system configuration: Workpiece carriage: Servomotor (1.0 KW) Drive and control the feed; Guide for the cross roller to the load rail; Preloaded ball screw drive, grease lubrication.
Oscillator: single servo or stepper motor control using mechanical reciprocating oscillation mechanism, amplitude 0-4mm adjustable, oscillation frequency variable frequency stepless speed regulation.
Protective cover: the use of fully enclosed protective cover, can play an effective protective effect, but also easily from the surrounding open, adjust the operation and maintenance convenience.
