Grease lubrication
Main use: Carving wood, bamboo, ordinary PCB, PVC, PMMA, plastic, two-color board (ABS) and other non-metals, and also can carve soft metal surfaces such as gold, silver, copper, aluminum, and lead. (Please note that this is a woodworking spindle, which can only be used for woodworking and aluminum products, not steel products. If you need steel products, please check the metal spindle, thank you!)
●The working environment temperature of the spindle is usually -10~40.
●Before installing the first electric spindle to rotate the spindle head by hand, you should feel flexibility and no blockage.
P4 fully sealed angular joint bearings can extend the life of the spindle.
The longer the length, the greater the torque and the greater the power.
Careful assembly makes the spindle more precise.
The accuracy is 0.01mm, and the coaxial cable is less than 0.0025mm
1. Our main shaft uses 4 bearings.
2. Bearings are resistant to high temperature and low heat
3. The ball bearing has low friction, low noise and long service life.
5Pins Air Plug: No.1,2,3 connecting to Inverter U,V,w. Spindle Gnd connecting to Inverter Gnd.
ER25 Collet Nut balancing nut high grinding inner cone precision 0.01mm.
●When the spindle is stored and transported, the bearing condition inside the high-speed grease will change, and the customer should run it at low speed for 30 minutes. Then increase slowly at a speed of 3000 rpm, running for 20 minutes each time. The spindle and inverter should work together. The specifications and parameter settings of the inverter match the spindle parameters.
●To connect the inverter main shaft, the three-phase inverter power cord should be welded to the plug 1 (U), 2 (V), 3 (W) pin, and the grounded pin 4. After turning on the power, observe whether the spindle rotation axis always shows the direction. If it is inconsistent, turn it off immediately, and replace the two wires of the three-phase power supply connected to the inverter and the spindle.
●Before using the spindle every day, it must run at low speed for 15-20 minutes. Clamp the cutter on the spindle, the chuck nut, chuck, and cutter must be clean enough. The shank inserted into the chuck must be larger than 15mm.
