We are offering cam grinding machine. the cam grinding machine manufactured by us is particularly used in the grinding of numerous cylindrical portfolios. Our cam grinding machine is very accurate and will surely give an excellent output. Excellent & stable power supply, quality speed control, hydraulic system and coolant system are some of the key features of our cam grinding machines. Other uses of our cam grinding machine is in die grinding, automobile camshafts and many more. So go for our cam grinding machines and we assure that you will not be disappointed. Operating principle this cam grinding machine is specially designed for grinding of various cylindrical profiles. It was originally developed for grinding punches used in the pharmaceutical (tablet making) machines. A master-cam (mc) is required which is then used to generate a generating-cam (gc) the gc in turn is used for grinding profile of components. An mc is an exact (one-to-one) replica of the finished profile. From the mc a gc is made. This generating cam is then used for producing the profiled components. The gc is made on cam grinding machine itself using the mc.for grinding the cam/profile on a work-space the machine has a stationary follower on which the gc rests. The rotation of the gc provides oscillating movement to the work-head which is holding the work-piece. The gc coordinates the rotary & radial movements required for developing the necessary profile on the work-piece.specificationsthe cam grinding machine consists of following major assemblies:-work headwork slide (longitudinal slide)longitudinal positioning mechanismwheel headwheel head slide (with hydraulic rapid retract)wheel head cross feed mechanismfollower positioning slides (x & z direction)feed mechanism for x & z positioningsub-baseelectrical controlshydraulic system & coolant systemwork spacecenter height - 150mmadmit between wkhd & registration device – 200mmmaximum od of the cam profile –40mmmax.

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
