Description:

Tool changing structure is advanced so that the signal and tool changing movement could be reliable and stable. Tool changing structure is advanced so that the signal and tool changing movement could be reliable and stable. 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. The GMN import bearings and engine oil are used to ensure high performance of the spindle. The Motor Spindle can additionally store the encoder and have the rigidity tapping function. It can be used in the numerically controlled production center.Tool changing structure is advanced so that the signal and tool changing movement could be reliable and stable. 

Applications:

Applicable scope: It is mainly used for the circular carving and drilling and milling of the hardware, glassworks and woodworks.This product is suitable for Engraving machine or Engraving and milling machine and Lock industry. 

Competitive Advantage:

Product features:
Infinitely variable speed transmission for frequency changer with wide speed range,Low noise, little vibration,Constant power spindle with low rotating speed and high torque; Low rotating speed used for drilling and milling or rough machining;good stability, high processing precision, High rotating speed used for engraving and milling or fine machining. This product has wide application.Adopt the ceramic core Aerial plug, more safe and reliable,The front end of the bearing use the water-cooling equipment , the cooling effect of the spindle is better. The durable years of the Bearings gets more longer.
