PMC-32060NC Cylindrical Grinder (NC Type)

 
Machine may be shown with optional accessories.

Victor NC type cylindrical grinder is easy to setup through conversational control panel yet greatly improves grinding accuracy and stability. Because wheelhead infeed is driven by servo motor, therefore grinding operations are easier and more convenient.

FEATURES: 
  • Wheelhead infeed is driven by servo motor for easy setup and grinding convenience. Easy to set sizes, feed amount, and feed rate to maximize productivity.  It allows direct change to automatic feed once manual feed is accomplished without changing program
  • Machine structure is manufactured from high quality Meehanite cast iron, heat treated and stress relieved before machining.  Slideways are high frequency hardened and precision ground.  Utmost material stability for deformation free and outstanding wear resistance
  • The variable speed spindle head runs on precision bearings, assuring greater spindle stability and providing outstanding accuracy for external and internal diameter grinding and face grinding.  Variable speed is driven by servo motor
  • The grinding wheel head is precision machined from high quality alloy steel SNCM-220.  Normalized, tempered, carburized, sub-zero treated, precision ground, and mirror-effect treated.  Hardness reaches over HRC 62º.  No deformation to ensure maximum wear resistance and accuracy
  • The wheel spindle runs by using a special hydrostatic bearing that is designed for precision grinding work.  It features high speed, no friction between metals, no heat generation, deformation free, extra high accuracy and continual use
  • The slideways of the table and the wheelhead are lubricated by an advanced automatic hydrostatical lubrication system which provides smooth movement, feed accuracy, and superior grinding accuracy
NC = NC computer controlled with conversational operation control for easy setup and grinding convenience, servo motor automatic infeed, and hydraulic traverse
