- 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 specific 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 Profile 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 / Hydraulic cylinder with end cushioning device for good damping effects at the end of each Stroke & with solenoid valves for soft table reversals 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 flow. 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 filled for Life for long trouble free service.
