ER20 Collet and Nut Precision crafted ER20 collet and nut, high precision and reduced the rate of knife breakage.	Four Bearings Using optimized 7 series P4 grade 7002 and 7005 bearings, this series of bearings has strong hardness and rust resistance, as well as dynamic balancing technology, the actual runout off of the spindle is close to 0.01 mm, the precision tapered bore is less than 0.005mm, high precision and durable.	Air Cooling Methods Using a scientific fan design that can use air circulation to cool the heat generated by the spindle at high speed, the heat dissipation effect is better, and the smooth and stable operation of the spindle can be well improved. At the same time, there is no need for water pumps and water pipes, and the spindle is air-cooled and dissipated, making it more convenient to use.

Aluminum Casing The body shell of the spindle is made of aluminum alloy. Compared with stainless steel, the aluminum material has better heat dissipation performance, and the surface is smooth and does not rust.	Pure Copper Coil The conductivity of the pure copper coil is very good, which can effectively exert electric energy, reduce consumption, and dissipate heat very well.	No Punching Required There are installation holes on both sides of the machine, no need to punch holes, users can install the machine according to their own needs according to different hole distances, which is more convenient to use

Dust Proof Design The stainless steel seal design at the front end of the spindle can prevent dust or impurities from entering the interior of the spindle, which can better extend the service life of the bearing.	Wire Box The upgraded version of the top junction box makes the spindle wiring simpler and safer. The wiring method of the spindle motor and the inverter is as follows: VFD's U= Spindle's U1 VFD's V= Spindle's V1 VFD's W= Spindle's W1 Connect any 2pin terminal "R", "S" or "T" of the inverter to "220VAC".	Low Noise Humanized noise reduction design, low noise when the spindle is running, can create a more comfortable working environment.

220V Square Spindle Motor

Basic Parameters:

• Cooling: air-cooled
• Circulation: less than 0.01 mm
• Precision taper bore: less than 0.005 mm
• Bearing lubrication: grease
• Collet size: ER20
• Bearings: 4 pieces of high quality bearings, class P4

1. Structural features

1) High speed electric main bearing all adopt the Ceramic bearing, axis sets of loading, Improve spindle in the high-speed rotation supporting stiffness and precision grinding.

2) Before driving, rotation of the shaft by hand.Spindle high speed rotation caused by temperature rise, use of cooling liquid circulating system to eliminate.

 

2. Instructions for use

1) In use, must first connect the cooling water pipe, make spindle connect cooling water and then start.

2) Before driving, turned by hand spindle. If sensory block is not flexible, you should troubleshoot, and then check the direction of rotation of the spindle from the spindle end to see if the match should rotate counterclockwise power wiring should be changed to make it consistent.

3) Before driving, cooling water for grinding workpiece can’t be in the front end of the spindle cover, to prevent the front bearing cover slot inlet burning motor and bearing. the motor must not enter the water, after turned on of the motor, when you live in grinding the workpiece to open the grinding of workpieces coolant. First off the workpiece coolant shutdown, and then close the spindle motor.

 

3. Maintenance and Service

1) Motorized spindle by medium frequency power supply rated voltage, frequency should be consistent with electric spindle technology parameters, motorized spindle rotational speed can change the frequency to adjust, also directly proportional voltage change.

2) When the spindle is temporarily not in use, should use compressed air to blow the coolant water,to avoid rusting, plug the hole. Spindle surface should be coated with anti rust oil. The shaft end protecting device, placed in dry place.

3) If replacement the spindle of bearings, best professional and technical personnel from the replacement. Use special tools, stator coil does not to be removed.
