Clean exterior surfaces with mild cleaner. DO NOT use solvents.

Check the hydraulic counterbalance pressure according to the machine's specifications.

Place a dab of grease on the outside edge of the fingers of the tool changer and run through all tools".

Monthly

Check oil level in gearbox. Add oil until oil begins dripping from over flow tube at bottom of sump tank.

Clean pads on bottom of pallets.

Clean the locating pads on the A-axis and the load station. This requires removing the pallet.

Inspect way covers for proper operation and lubricate with light oil, if necessary.

Six months

Replace coolant and thoroughly clean the coolant tank.

Check all hoses and lubrication lines for cracking.

Annually

Replace the gearbox oil. Drain the oil from the gearbox, and slowly refill it with 2 quarts of Mobil DTE 25 oil.

Check oil filter and clean out residue at bottom for the lubrication chart.

Replace air filter on control box every 2 years.

Mineral cutting oils will damage rubber based components throughout the machine.

Troubleshooting

This section is intended for use in determining the solution to a known problem. Solutions given are intended to give the inpidual servicing the CNC a pattern to follow in, first, determining the problem's source and, second, solving the problem.

Use common sense

Many problems are easily overcome by correctly evaluating the situation. All machine operations are composed of a program, tools, and tooling. You must look at all three before blaming one as the fault area. If a bored hole is chattering because of an overextended boring bar, don't expect the machine to correct the fault.

Don't suspect machine accuracy if the vise bends the part. Don't claim hole mis-positioning if you don't first center-drill the hole.

Find the problem first

Many mechanics tear into things before they understand the problem, hoping that it will appear as they go. We know this from the fact that more than half of all warranty returned parts are in good working order. If the spindle doesn't turn, remember that the spindle is connected to the gear box, which is connected to the spindle motor, which is driven by the spindle drive, which is connected to the I/O BOARD, which is driven by the MOCON, which is driven by the processor. The moral here is don't replace the spindle drive if the belt is broken. Find the problem first; don't just replace the easiest part to get to.

Don tinker with the machine

There are hundreds of parameters, wires, switches, etc., that you can change in this machine. Don't start randomly changing parts and parameters. Remember, there is a good chance that if you change something, you will incorrectly install it or break something else in the process6. Consider for a moment changing the processor's board. First, you have to download all parameters, remove a dozen connectors, replace the board, reconnect and reload, and if you make one mistake or bend one tiny pin it WON'T WORK. You always need to consider the risk of accidentally damaging the machine anytime you work on it. It is cheap insurance to double-check a suspect part before physically changing it. The less work you do on the machine the better.

EXTENDING BEARING LIFE

Abstract：Nature works hard to destroy bearings, but their chances of survival can be improved by following a few simple guidelines. Extreme neglect in a bearing leads to overheating and possibly seizure or, at worst, an explosion. But even a failed bearing leaves clues as to what went wrong. After a little detective work, action can be taken to avoid a repeat performance. 数控机床英文文献和中文翻译(5):http://www.youerw.com/fanyi/lunwen_78569.html
