Paragon USA | Universal Cylindrical Grinding Machines, CNC (Heavy Duty)
Brochure 
Every Paragon cylindrical grinder is designed and manufactured based on the following management concepts: Application of the newest technologies and innovation, endless improvement and progress and customer satisfaction. Assembly is carried out in strict compliance with ISO 9001 directives. All machine bases are manufactured from high quality Meehanite cast iron with a low center of gravity.
Universal wheel-head: Rigid and precise with a powerful 5-hp motor achieving peripheral speed 45m/s. Equipped with class C1 ballscrew (40mm dia.) and Heidenhain sub-μm linear scale with full close loop feedback.
Overall, the machine achieves +/- 0.5 μm repeatability accuracy
Grinding Spindle: Made of high quality alloy steel (SNCM-439).
Hydrostatic Bearings: No metal to metal friction, no overheat and no deformation and no oil leakage. The hydraulic and lubrication system has independent temperature control, providing minimum thermal displacement.
Hydrostatic Guideways: Hand scraped and features an oil lubrication system which reduces the metal friction and guarantees constant high accuracy.
Workhead: A rigid design, driven by servo motor, features reliable and precise operation. NN roller bearings and angular contact bearings in the workhead spindle reduce edge stress and friction, improving concentricity and surface finish of work piece. The table is enabled to swivel between 30° (clockwise) ~ 90° (counterclockwise).
Tailstock: Flexible and easy operation, equipped with hydraulic actuated barrel retraction by foot peddle and manual handle for easy workpiece loading and unloading. (M.T.4 Taper Center) Center pressure can be adjusted for high precision for small and thin workpieces.
CNC Controller: Rexroth MTX Micro color screen with the latest technology in digital control system. Powerful processor can shaorten CNC and PLC processing time. Compact multi-server drives, which smaller installing space and high processing accuracy.
Paragon’s self developed conversational interface software can get users started quickly.
