CNC Ring Grinding Machine Standard Features & Description of Machine

Standard features & description of machine (key features & description of the machine) Ring grinding machine which can accommodate tungsten carbide ring and entry guide rolls grinding with three axis CNC and driven by CNC controls. The special feature of this machine is the modular design concept incorporating rigid, multi-piece grey cast iron base housing all units such as grinding wheel head, work head, in feed slide and oscillation slide assembly. The solid construction provides rigidity for the machine during grinding. Base is made of FG 260 graded casting, stress relieved and provided with ribbings and rugged in construction to avoid any vibration resulting in better dampening effect. All slides and housing are made up of FG-260 graded cast iron. All castings are stress relieved. Guide way seating areas are scraped very accurately to have a good contact for the Guide way system. Fitted with linear motion guide ways of rigid linear rail and carriage block for the wheel head in feed axis Centralized lubrication for linear bearings and ball screw assembly. Preloaded ball screw of Grade C3 for both linear axes. Oscillation axis is with Turcite lined and with recirculation type of lubrication. Oscillation axis is driven with a preloaded ball screw grade C3. The grinding wheel spindle is driven with an AC induction motor. Wheel spindle is suitable for the front nose of taper 1:6. Work head spindle is driven by AC servo motor and of variable speed. Work spindle front nose is of standard A2-8 design. Manually operated expansion arrangement for work holding. Precise positioning of grooves of pass profiles with linear scale interface for the table axis. Provision of grinding cycles for plunge grinding and deep grinding. Coolant filtration system is offered with Centrifuge. Work room enclosure with top cover to take care of the grinding mist in the operational area.
