we are offering internal grinding machine. Since we are among the leading internal grinding machine manufacturers. Our internal grinding machine is specifically designed to achieve high level of accuracy. We do not believe in compromising on the class of our internal grinding machine, hence continual & strict quality checks are applied, before it is presented to you. With very reasonable rates for the top merit of efficient and durable internal grinding machine, we invite you to try our internal grinding machines.optional accessorieswork head center, revolving center,wheel balancing stand,radius / angular / diamond roller dressing devices,magnetic separator,two point steady rest.maintainencethe machine requires practically no routine maintenance. The grinding spindles are mounted on super precision bearings, lubricated with long life grease & sealed for life. The same applies to the work head spindle lubrication. The wheel-side runs on x roller linear bearings. These are grease lubricated & require relubrication once a month. The feed nut & the work slide are oil lubricated & require relubrication once a shift.work table : table travel is effected by means of hydraulic cylinder. It’s speed can be infinitely varied by speed control valve. Table stroke can be varied by means of dogs provided on the table. Work slide has a micro feed for shoulder grinding and for control of axial dimensions.work head : work-head is mounted on a swivel base to facilliate grinding of steep tapers. It has a d.c. Drive permitting stepless speed variation. Work-head spindle is supported on super precision(iso – p4) antifriction bearing providing exceptionally high running accuracy & rigidity. It is grease packed for life.wheel head : wheel head slidle moves on preloaded linear bearings. This guarantees absolutely stick-slip free movement and repeat positioning accuracy. Wheel spindle is supported on super precision(iso – p4) antifriction bearings. It is cartridge type and packed with long life grease which ensure maintenance free running.rapid approach/retract is by hydraulics where as grinding feed is manual. Minimum feed resolution is 0.001 mm(one micron). Auto feed machines have stepper motor feed drive.tail stock : the ram is carried on precision honed sleeve and is kept under adjustable spring load. Hydraulic actuation can be provided optionally.internal grinding attachment : the spindle bracket is hinged on the wheel head and can be quickly lowered into grinding position to register accurately against solid stop. The unit has independent drive motor.hydraulic power pack : hydraulic power pack is housed outside the machine. Thereby the thermal effect on the machine is eliminated. It also facilliates easy accessibility for manitainence.electrical cabinet & control : the electrical cabinet is mounted on one side of the machine. The logic controls are inside operator console.standard equipments : wheel-flange with grinding wheel(mounted on the machine), wheel flange remover, wheel balancing arbor, hardened dead centres(2), related hydraulics, electricals, coolant system, set of service tools & operator’s manual.optional equipments : wheel-flange, wheel balancing stand, angle dressing device, radius dressing devices, work holding devices, magnetic separator for coolant, precision live center(tir < 0.001mm) steady rests.

Application: Bearing components, automotive components. Gear bore grinding Salient Features CNC or PC based control options. All slides on anti-friction bearings Auto-dressing &                                 dressing compensation On-Demand Dressing Suitable for super-abrasive grinding media.
