Machine Description

LM5020 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. The large Wheel Size of OD500mm With Improves the Cycle Time

Super rigid structure, stable without deformation. Double support grinding wheel spindle design features high speed operation to boost grinding performance. customized Fitted with wider wheel, suitable for efficient mass production.

Grinding Wheel Head

Grinding wheel driven by V belt drive and Twin support cartridge preload precision bearing spindle for achieve good surface finish and hi radial accuracy , Twin support spindle give hi rigidity in machine also increase load caring capacity of machine

Regulating wheel Head

Regulating wheel control by direct couple gear box with A/c variable speed control drive and Twin support 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

Machine have two main slide, Grinding wheel head is fix and Both slide give movement to regulating wheel head, Main slide have roller type guide way for reduce frication and to increase accuracy of slide movement and upper slide have dovetail slide to get hi rigidity and good grinding performance

Hydraulic Model Main slide function

Both Slide control by singe Ball screw nut and also have manual Lubrication system for smooth sliding

Machine have Micro feeding arrangement for move slide precisely Regulating Wheel Main Slide Manual Hand operated

NC Model Main Slide Function

Both Slide control by singe Ball screw nut and also have Automatic Lubrication system for smooth sliding

Lubrication system have Low Oil level and low Oil presser indication on HMI Main slide control by Ball screw and nut, servo motor, Servo planetary gearbox, HMI, PLC and MPG for accurately traveling

Heavy duty and high weight slide move with Smooth and accurate traveling in low power consumption is possible by Servo Planetary Gearbox

MPG give hi accurate and fast offset setting for grinding setup

Also give selecting Accurate feeding Pulse in 1micron, 10micron, 100micron

Auto infeed grinding cycle possible with adjustable Rapid stock, cutting feed and spark out, return cycle timing, lubrication timing

Regulating Wheel Main Slide Manual Hand operated

Dressing Slide

Both Dressing Slide have Spring Loaded Pilot operated Temples dressing And Eccentric back laver arrangement

which can give accurate straightness in grinding wheel and Regulating wheel Regulating wheel dressing slide have truing( swivel) angle and taper( inclination) angle

Regulating wheel Dressing Slide diamond holder have offset Arrangement

which can use for increase griping line to achieve good roundness, straightness and increase load caring capacity for long jobs

NC Model Dressing slide

Both Dressing slide Control by Gear Motor with A/c Variable speed control drive, LM Guide way and ball screw to get fine feeding and long life dressing for good ra value in jobs

Hydraulic Model Dressing slide

Both Dressing slide Control Hydraulic Cylinder , Direction control valve and Flow Control Valve to get fine feeding and long life dressing for good ra value in jobs

Blade Rest

Blade Rest is resting on main slide

Coolant System

Machine Have Aprox 300L Coolant tank , coolant tank have 3 partition for separate dust in coolant , Tank have 0.5hp pump Which can give 175L displacement of coolant

100L Magnetic Coolant Filter for remove magnetic particles ( Extra accessories) 100L Paper Band Filter for remove faros non faros and dust particles ( Extra accessories)
