BRIEF DESCRIPTION

Operating CNC Surface grinding machines is very much depended on the operator’s skill of programming, knowledge & experience. But with PINNACLE-make High Precision CNC surface grinding machines, the operating of machines is made simple, precise & the operator only needs basic knowledge of surface grinding operation. PINNACLE has developed customised screens which don’t need lengthy programming & programming codes skills but only needs to feed in step by step data of surface grinding.The regular developed canned cycles include Step Grinding, Continuous grinding, Plunge grinding & Face grinding. PINNACLE has also developed various Customised canned cycles against customer’s specic requirement.CNC series machine models are 2 Axes/3 Axes/4 Axes CNC controlled High Precision Surface grinding machines.These series machines are designed and developed to cater almost all surface grinding applications such as Prole grinding, Creep feed grinding & even Spline grinding using necessary special attachments/equipments.Longitudinal Movement i.e. X-Axis is driven through AC Servo motor directly coupled to Ball screws with Zero backlash Servo couplings for CNC 3 Axes machine / Hydraulic cylinder with end cushioning device for good damping effects at the end of each Stroke & with solenoid valves for soft table reversals for CNC 2 Axes machine over Precise Ground Prism-Flat guide ways.Vertical Movement i.e. Y-Axis is driven through AC Servo Motor directly coupled to Ball Screws with Zero backlash Servo Couplings over High Precision & Rigid LM Guide ways / Precise Ground Prism-Flat guide ways.Cross Movement i.e. Z-Axis is driven through AC Servo Motor directly coupled to Ball Screws with Zero backlash Servo Couplings over High Precision & Rigid LM Guide ways / Precise Ground Prism-Flat guide ways.All the Prism Flat Guide ways are Turcite B-Lined & LM Guide ways are equipped with Auto Lubrication unit has facility of Re-Circulating Filtration system with Low & High signal and Pressure drop signal for Constant Dust-free Hydro-dynamic ow. It gives high sensitive mechanism to achieve micronic movements with stick-slip free motion.Grinding Spindle-Cartridge is assembled with Imported SUPER PRECISION BEARINGS grease packed with Imported Grease lled for Life for long trouble free service.
