MISC. CHECKS

  • Air pressure set to 80-90 PSI
  • Drain Oil/Water separator
  • Look at Air lines for leaks, cracks & problems
  • Air solenoids for leakage/operation.  Spray WD-40 at the intake of the manifold
  • Coolant level, for leakage & hose cracks
  • Way lube level, lube to ways & lines.  Inspect for leaks, hose breakage
  • Check/replace way cover wipers (Identifying your waycover wiper material)
  • Perform Push/Pull Test on X & Y axis.  Should get no more than .0003” play.
  • Feel ballscrew motion by turning by hand. Look for smooth movement and minimal backlash.
  • Check Electrical connectors for tightness
  • Work lights Working?  Replace or troubleshoot as needed (WIR-0114)
  • ATC – Check ATC clips for tight hold on tools.  Replace loose ones. Check tool locater tabs for damage and replace as needed 
  • Incoming Voltage; adjust xformer taps so inverter is receiving no more than 240VAC input on legs L1, L2 & L3.  Tap to a higher voltage to lower the voltage to the inverter.  VMC Transformer Tapping Procedure.
  • Spindle belts/pulleys for wear/alignment. Pulleys that have the anodization worn off should be replaced or your belt life will be shortened.
  • Meg AC motors including spindle.  If you don’t have one, here is a simple one we recommend. Mega-ohmmeter
  • Check Taper Runout @ 10" if you have or can get a taper test tool.
  • Z axis counter balance chains (check for wear of chain & sprockets)
  • Check Y axis telescoping ball screw cover for excessive wear or tears. 

 

LUBRICATION

  • Clean waylube filter as needed with mineral spirits
  • Verify lube pump delivers one shot per 4 min.
  • Lube air solenoids with light oil or WD-40.

 

 COMPUTER

·         Backup parameters to disk if possible

FINAL CHECK

  •  Check to see all axes, tool changer, coolant, TC, and spindle all operate properly.
