MAiNTENANCE
• Alternave choices include Perkins Perlube WL-68, Tonna 68 (Shell), Vactra No. 2 (Mobil),
Way-lube 68 (Sunoco), WayLube 68 (Texaco), Febis 68 (Esso) or equivalent oil.
• Clean o the cover and surrounding area to remove debris before relling the oiler reservoir.
• Periodically inspect way surfaces and ball screws to conrm a proper oil lm is present.
Absence of an oil lm can be an indicator of clog oil lines or ngs.
The X, Y, and Z slideways have a thin layer of PTFE-lled acetyl plasc bonded to each sliding surface.
The material is commonly known under the trade names of Turcite
®
or Rulon
®
.
This is state of the art technology for oil lubricated slideways and superior to plain ground surfaces
or hardened and chromed surfaces. No data is available on how long the material will last on the
PCNC, but there have been no reports of appreciable wear, even on mills that are reported to have
seen more than 5000 hours of operaon.
If you use the lubricaon system and keep the protecve bellows in good shape, the slideways are
not maintenance items.
A shot of lubricaon should be given aer every four hours of operaon and aer the mill has stood
unused for 48 hours or longer.
If the mill’s lubricaon system becomes clogged, brass oil system ngs can be cleaned by soaking
them overnight in a degreaser or solvent like WD-40. Replace clogged plasc oil line tubing.
9.1.4.1 Manual Oiler Specifics
• The manual pump is spring loaded. Retract and release the plunger and the spring force
creates light hydraulic pressure to push oil through the lines. You can get the oil out quicker
by pushing the plunger a bit, but too much force can pop o oil lines. A shot of lubricaon
should be given aer every four hours of operaon and each me the mill is powered on.
• You will have a more uniform distribuon of oil if the mill is moving when the hydraulic
pressure is applied.
• The manual oiler draws oil from the reservoir on the pull stroke and delivers it to the mill on
the push stroke. If at some point the manual oiler seems much easier on the push stroke,
make certain that you do not have a broken oil line.
• Extreme axis posions can expose the lubricaon system channels that are cut into the way
support saddle surfaces. If the pump is used in those posions, the hydraulic force of the oil
will not apply it throughout the mill as intended. Instead, the oil will simply squirt out at the
point where the oil channel is exposed.
• Aer a long period of inacvity, the lubricaon system may need several pumps as oil may
have drained from the Z-axis lines.
