Instructions for use:

  • Spindle working environment temperature is usually -10 ~ 40 .

  • Before installing the first electric spindle axis head turned by hand, should feel flexible, non-blocking phenomenon.

  • 500V shake table to check the stator insulation resistance of not less than 50MΩ.

  • The internal electric spindle into the base 2,3 inspection meet the requirements, in strict accordance with the electro~spindle mounting position of installation, tighten the screws, not loose in the spindle into the base.

  • Spindle storage or disable power after six months, to be replaced with new grease before re-use, otherwise it will affect the life of electric spindle.

  • Spindle must be supporting the use of inverter, inverter selection should match the voltage, power and frequency range spindle. Set the drive first set reference frequency inverter, inverter reference frequency spindle by the highest frequency settings, such as the reference frequency of the inverter is not set (the reference frequency of the inverter is set to 50Hz at the factory), begins to run electricity spindle immediately burned. Frequency spindle is generally 0 ~ 400Hz, so the reference frequency of the inverter to be set at 400Hz.

  • The three-phase power inverter and electric spindle connection, three-phase inverter welding power cord plug 1 (U1), 2 (V1), 3 (W1) feet, 4 feet for the ground. Then drive to the external power connector. After power inverter jog, observe the direction of rotation of spindle motor spindle indicate whether the same direction as the rotation direction of the inconsistency should be immediately shut down, swap the drive with two electric spindle connected to a three-phase power supply. Spindle prohibited run in the wrong direction of rotation.

  • In order to prolong the life of electric spindle, spindle or new spindle bearings should be replaced with new low 8h after running up speed in the speed range, high speed operation and avoid direct shorten bearing life. On vacation in the future, turn the electric spindle load running half an hour, and then start working.

  • When installing electric spindle collet, should be cleared within the first hole and clean surface dirt collet shaft, so as not to reduce the precision collet assembly and disassembly when not equipped with tools, so as not to damage the tool, note that the clamping clip prohibit excessive force when head.

Cast Aluminium Bracket: 65mm

Diameter :65mm

Material: cast aluminium


  • Compared with the aluminium profile fixture,the accuracy is much higher , and it is hard to deform.

  • Inner wall is very smooth, outer walls is sandblasted, relatively fine uniform, but not very smooth,.

  • Cast aluminium fixture is much heavier than aluminium profile fixture

Product Description:

  • Cast aluminium fixture is high quality aluminium which is casting with a special manufacturing process ,compared with ordinary aluminium ,This product has toughness, strong shock resistance, high hardness and strong antioxidant activity.


  • Cast aluminium fixture is mainly used for fixation of ancillary products, thereby ensuring the verticality of balancing and ancillary products, ancillary products to improve running accuracy, reduce noise, reduce the accumulated error.
