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.

Competitive Advantage:

Constant power spindle with low rotating speed and high torque; Low rotating speed used for drilling and milling or rough machining; High rotating speed used for engraving and milling or fine machining. This product has wide application.Low noise, little vibration, good stability, high processing precision
Infinitely variable speed transmission for frequency changer with wide speed range
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.

Notes for Use of Motor Spindle: 

1, Before using the water-cooled motor spindle, it must be ensured that the cooling system is working properly and working without cooling condition is strictly forbidden. Cooling water calculate by 1 liter per kilowatt minute. The minimum flow rate of cooling water is not less than 5 liters per minute. The cooling water pipe and the water nozzle connection must be reliable to prevent leakage.

2, In the process of saving and transporting motor spindles, the high speed grease in the bearings could be changed. So before using, the spindles should run in low speed for a period time at first. Running must start from the minimum speed of the spindle and add speed to differential growth by 3000rpm after 30 minutes. Each level is run in 20 minutes. If just start using in high speed without running, abnormal noise and heat would happen then the using life will be shortened. In the long-term use of the electric spindle, it should be working(in low speed) at least 15 to 30 minutes within one week.
3, The motor spindle must be preheated before processing every day. Until reaching the processing speed and running for 15 to 20 minutes, the spindle could start fine finishing. The spindle should stop 2 hours to prevent mechanical fatigue every day, so as to prolong the life.
4, The spindle should rotate in the specific direction.
5, Cooling the spindle by water cooling machine should control the temperature between 22 to 25.
6, The spindle using gas seal should dry and filter its gas source by the water oil separator before using. The atmospheric pressure is required to be 0.25MPa and filtering accuracy should be 5µm, or the bearing would be damaged.
