Maintenance and protection knowledge of machining center tool holder

March 17, 2021

Generally speaking, the winter operation of machining center toolholder needs to start with preheating, antifreezing and cleaning.

1、 Preheating
In winter, when the machining center starts up, it needs to warm up for 10 minutes before it works. If the machine is not used for a long time, the preheating time should be extended accordingly.

2、 Antifreeze
The general principle of antifreeze is to ensure the fluidity of machining center fluid and avoid condensation when the temperature is too low.
1. Ensure that the lubricating pump works normally and works after preheating.
2. The fluidity of cold liquid must be ensured. If the coolant in the water tank cannot be guaranteed not to condense, it is better to pour out the water and drain the coolant in the main shaft and water pipe to prevent freezing and leading to blockage or cracking.
3. Check the set temperature of the oil cooler. It is recommended to keep it at 26.28 ℃.

3、 Cleaning

1. Clean the impurities in the cutting fluid and the cutting generated in the process in time, so as to avoid the blockage of cold circulation, drainage and travel obstacles.

2. Clean the lead screw regularly to prevent foreign matters sticking on the lead screw. The lead screw is very important in the equipment, which determines the accuracy of the machining center, and the lead screw also plays an important role in the transmission process.

3. The whole machining center should be kept dry and clean.
In addition, in order to ensure the accuracy of the toolholder, especially the taper surface of the toolholder, it is not recommended to do antirust treatment. Therefore, we need to do a good job in the daily maintenance work. In fact, the anti rust of knife handle is very simple, as long as we care more carefully: wear gloves when taking off; use air gun to blow out the coolant when taking off the used knife handle, so as to avoid residues in the slit or hole; and then simply wipe it with soft cloth sprayed with anti rust solution. In addition, reasonable selection of coolant, timely grasp the change of its pH value will also be helpful to the rust prevention work.
