Regular oil change
Cutting oil is the lifeblood of a centerless grinder, which can make the important components of the machine run normally. If you change the cutting oil irregularly, these components will fail sooner or later, leading to time-consuming and expensive repair costs.
So don’t let dirty oil hinder your production operations.
Relevant reminder: The oil filter should also be replaced regularly to ensure that the cutting oil is clean.
Clean up grinding debris
A lot of debris is generated every time the machine coolant passes through the machine.
Suppose your grinder operator shuts down the machine at the end of the shift. The coolant is discharged from the machine, and the chips will remain and harden. This process keeps repeating, unknowingly, the chips will keep accumulating, and they may have accumulated in places where the chips should not appear. Then the accumulated chips prevented the door of the machine from closing properly, and the coolant leaked to the entire floor.
Finally, the centerless grinder must be turned off to dig out the hardened chips.
Cleaning up the debris may be a simple task, but it will result in a decrease in output or production waste again when the machine is restarted. If debris enters the sealing parts, or let the coolant flow into the place where it should not flow, it will cause a more serious situation. It may accelerate bearing wear and cause huge downtime problems.
The reminder of the above situation is:
The large amount of chips accumulated in the grinding operation must be kept away from the internal components of the machine to avoid chip abrasion and shorten the service life of key components.
At the end of each shift, take ten minutes to spray the machine and dry it. It can not only eliminate major problems, but also make the machine look cleaner and more comfortable.
Check your positioning pins
The positioning pin is responsible for maintaining the fastening and positioning of the machine parts. The movement or wear on it may lead to inaccurate calibration, resulting in poor quality of parts or poor finish of parts.
Perform preventive maintenance
Preventive maintenance is to track the wear and tear of the machine to solve small problems that have not yet formed a major problem.
Preventive maintenance has been shown to:
●Extend machine life
●Reduce emergency repairs
●Improve machine efficiency and reliability
Therefore, time should be spent establishing and implementing preventive maintenance plans on high-priced machine tools, including centerless grinders.
Identify critical parts and keep inventory
We recommend that you record all grinding machines on a spreadsheet. And give priority to the influence of machinery on product transportation.
●How long will a machine stop to endanger the transportation of finished products?
●Is there a buffer time between the key machine and the next operation?
●If yes, how long is the buffer time?
Once you have determined which is the most important grinder, you can decide which parts to buy and whether you need to stock it.
By grading potential spare parts, this time-consuming task can be simplified:
Know the parts that need to be used and the parts that must be owned in order to avoid downtime, and then make a purchase or inventory plan.
Check hoses, belts and cables
Before each shift, please look around the machine and check the hoses, belts and cables for wear and looseness.
