Palmary GV-70 Engine Valve Seat Grinder

• 1. Stable and Rigid Spindle Head


• (1)The spindle runs on precision bearings assuring maximum spindle stability.


• (2)The spindle head provides variable speed changed by frequency inverter.


• 2. Precision Wheel Head


• (1)The grinding wheel spindle is precision machined from high quality alloy steel SNCM-220 normalized tempered carburized and sub-zero treated precision ground and mirror-effect treated. Hardness reaches to over HRC 62° No deformation maximum wear resistance and lifetime accuracy are assured.


• 3. Special Hydrostatic Bearing


• (1)The Wheel spindle runs by using a special hydrostatic bearing and is especially ideal for precision grinding work. It features high speed no friction between metals no heat generation deformation-free extra high accuracy and continual use.


• 4. Advanced Hydrostatic Lubrication System


• (1)The slideways of the table and the wheel head are lubricated by and advanced automatic hydrostatic lubrication system. This provides various features such as extremely smooth movement added feed accuracy and superior grinding accuracy.


• 5. Rigid Machine Structure


• (1)The machine structure is manufactured from high-quality Meehanite cast iron heat treated and stress relived before machining.


• (2)Slideways are high frequency hardened and precision ground. Maximum material stability for deformation-free and outstanding wear resistance.
