Description:
The GMN import bearings and engine oil are used to ensure high performance of the spindle. Tool changing structure is advanced so that the signal and tool changing movement could be reliable and stable. The Motor Spindle can additionally store the encoder and have the rigidity tapping function. It can be used in the numerically controlled production center.GDL125 series Motor Spindle is the automatic tools changing (can store encoder) spindle designed by our company. It adopts six-pole motor-driven system and the BT40 knife handle, could usually be used in the quick processing of different materials with 12000rpm. The multichamber protective measure including double-layer sealing device and air sealing conformation can efficaciously provide liquid from getting in and keep Motor Spindle working for a long time.
Applications:
Applicable scope: This product is suitable for Engraving machine or Engraving and milling machine and Lock industry. It is mainly used for the circular carving and drilling and milling of the hardware, glassworks and woodworks.
