Its amazing how little preventive maintenance is not performed within the majority of manufacturing companies today. I am often asked by maintenance personnel on how other companies deal beyond CNC equipment. What is my answer? This is typical if it is not broke do not fix it.
What I described below is how you can set up a preventive maintenance program based on little knowledge of CNC and the maintenance and the least amount of downtime covering the most basic and important parts of a PM program. The items below will save you more money down and prevent a future rupture.
Minimum basic preventive maintenance program CNC
1. Check the oil levels for machines - Tower, B-axis, and ATC magazine gear boxes, gear box spindle, hydraulic. If you have a loss-fix it. They are contaminating the refrigerant, reducing the tool life and put more contaminants in the oil system every time you fill the tank.
2. pure chip from every corner of the machine.
3. Pull back the waycovers and clean the depressions in the recirculation zone of balls and coolant drain properly and prevent flooding in your bearing seats.
4. Check for lubricant on the box so machines. There should be a line from the wiper every time you reverse the axis on the leading edge.
5. Check the clamping force of the spindles every 3 months-this is a second check PM 15. This control is so important-it could save a spindle, increasing the length and quality of the pieces.
6. Check your change pallet alignment and operation if equipped. The last thing you want to do is throw a device in a car. Even chip cleaned from under the pallet and B-axis
7. Perform a basic control cable, pipes and electric fans outside and inside electrical control panels. Do not forget to check the transmission fans or fans of the computer as well.
8. Clean and replace filters if necessary.
9. Check your CNC alignment tool change. Maybe it's not the easiest for a novice, but at least look for something obvious. Correct any CNC machine tools that are falling on the occasion. There is a reason! Do not let it go. so will cause damage to waycovers, ATC follower and gearboxes, the fingers of tools and spindle damage.
10. Check the backup batteries and make backup copies of the parameters via the DNC system. In times of economic crisis today many machines are turned off for long periods of time. I hope you have backup copies or original cards.
