The New-Concept Gear Finishing Machine Fills A Gap Between Shaving Machines and Polishing Machines. CNC GEAR GRINDING MACHINE SRG-22 SRG-22 Design Concept The CBN electro-deposited worm wheel is employed to offer high-speed gear grinding (at the maximum spindle speed of 8,000 rpm). Any distortion caused by heat treatment can be completely corrected, and any dent can be eliminated. JIS Class-0 pitch and leads and Class-2 tooth profiles can be easily obtained. Honing cost can be drastically reduced if this machine is used in the preceding process. Reasonable tool and machine costs (close to shaving cost) can be maintained. This machine is most suitable for mass production parts.
