Advantages

• Our spindle uses 4 bearings,P4 fully sealed angular joint bearings can extend the life of the spindle.
• Bearings are resistant to high temperature and low heat
• The ball bearing has low friction, low noise and long service life.
• ER32 Collet Nut balancing nut high grinding inner cone precision 0.01mm.
• Aluminum profile body, not easy to deform, anodized surface treatment, shell not affected by time,
• Fast heat dissipation design,with its own cooling fan, good cooling effect,also improved spindle life.
• Easier installation with flange.
• Internal pure copper coil rotor, strong conductivity, good heat resistance, strong motor power, more durable.

Spindle dimension drawing

Note

• 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 to the spindle, the three-phase inverter power cord should be welded to the plug 1 (U), 2 (V), 3 (W) pin, and the grounded pin 4.
• Careful assembly makes the spindle more precise.

Main use:

Carving wood, bamboo, PMMA or other plastic,MDF board,ordinary PCB, PVC, Acrylic, wood,composite board plywood,two-color board (ABS) and other non-metals,and also can carve soft metal surfaces such as gold, silver, copper, aluminum, and lead.
