Palmgren 10" x 20" Automatic Surface Grinder

PALMGREN 10" X 20" AUTOMATIC SURFACE GRINDER - 9682124

Palmgren's 10" x 20" precision automatic surface grinder is designed and built to increase productivity, maximize performance and accuracy by offering the latest technology in automatic controls. This surface grinder delivers flat surfaces with close exacting tolerances and high quality surface finish refinement.

Features:

• Meehanite cast iron construction – stress relieved to minimize vibration while maximizing rigidity and accuracy
• High precision cartridge type spindle with lubricated for life multiple anti-friction bearings that are radially and axially pre-loaded for quiet vibration free operation and longer spindle life
• The spindle bearings are class 7 (P4) super precision angular contact ball bearings which have been accurately measured, selected and pre-loaded and then assembled in a temperature controlled room to assure stable noise free rotation
• Runout at the spindle nose taper is less than 0.000070" (0.0020mm) TIR
• Hydraulic feed machine features hand scraped and Turcite B coated way system on both the table longitudinal and cross feed, providing low operating friction, high vibration dampening and long wear capabilities
• Automatic lubrication system provides constant lubrication of critical wear areas
• Spindle and motor are a direct drive design, one piece design. The motor/spindle is dynamically balanced to attain a vibration displacement under 0.0006”/s (0.105mm)
