Machine Description

LM 3/ LM4 Meet The Criteria For High Productivity Centerless grinding , the Machine is suitable for both in-feed and Thru-Feed Grinding of small to big size part. Machine designed for take high accuracy with high load caring capacity

Grinding Wheel Head

Grinding wheel driven by V belt drive AC Motor and VFD Controlled and White Metal Hydrostatic Bush bearing spindle for achieve good surface finish and hi radial accuracy , External Pump lubrication & Oil safety Future give very good Spindle and bush life.

Regulating Wheel Head

Regulating wheel control by direct couple gear box with A/c variable speed control drive and cartridge preload precision bearing spindle for achieve best grinding performance and hi radial accuracy for every size of jobs

regulating wheel head have adjustable inclination angle and swivel angle for adjust job feeding rate and Grinding cutting position

Main Slide (X - Axis)

X-axis slide made form heavy duty cast base, Base slide have Preload Roller Type LM Guide way get hi rigidity and best grinding performance, Ground Ball screw, Servo motor Servo gear box to get high precision accuracy and controlled by CNC Controller.

This axis use for job cutting and dressing compensate purpose.,

This slide have swivel angle to adjust taper of job in Plunge grinding. Auto and Manual lubrication is available in this slide & ball screw.

Hand scrapped Upper dovetail slide design reinforce the feeding stability & rigidity in regulating wheel head. also have manual Lock Arrangement for upper slide

Both slide and Ground Ball screw nut have central Automatic Lubrication system for smooth sliding

Lubrication system have Low Oil level and low Oil presser indication on screen

Dressing Slide

Grinding Wheel Dressing (Y - Axis , Z- Axis )

Grinding wheel dressing unit made by Two Axis (Y,Z), Both Slide Servo Motor, Ball screw and LM Guide operated . It is Controlled by CNC controller , Z axis Spring loaded and template operated to get precise straightness in grinding wheel. Y Axis Taper adjustment available.GW Dressing unit angel give resistance from coolant

Regulating Wheel Dressing

RW dressing unit made by Lm guide way, ball screw and VFD operated Gear Motor to give slide reverse and forward fine movement. Depth of cut done by manual hand operated. RW dressing have template & pilot operated dressing . Regulating wheel dressing slide have truing( swivel) angle and taper( inclination) angle

Coolant System

Machine Have Aprox 75L Coolant tank , coolant tank have 4 partition for separate dust in coolant , Coolant tank have 50L Magnetic Coolant Filter (optional) for remove magnetic particles Tank have 0.25hp pump Which can give 50L displacement of coolant
