Main purpose: used for wood, bamboo, ordinary PCB, PVC, PMMA, plastic, bamboo, two-color board (ABS) and other non-metallic carvings.

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.

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.
