Structural features1) 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. Maintenance and Service1) 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. ER20 Collet and NutPrecision crafted ER20 collet and nut, high precision and reduced the rate of knife breakage.Four BearingsUsing 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 MethodsUsing 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 CasingThe 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 CoilThe conductivity of the pure copper coil is very good, which can effectively exert electric energy, reduce consumption, and dissipate heat very well.No Punching RequiredThere 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 useDust Proof DesignThe 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 BoxThe 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 U1VFD's V= Spindle's V1VFD's W= Spindle's W1Connect any 2pin terminal "R", "S" or "T" of the inverter to "220VAC".Low NoiseHumanized noise reduction design, low noise when the spindle is running, can create a more comfortable working environment.
