6 tip when buy spindle motor

The spindle is a new technology that integrates the machine spindle with the spindle motor in the field of CNC machine tools. It has the advantages of compact structure, light weight, low inertia, low vibration, low noise, fast response, etc. It can reduce the gear transmission and simplify the machine tool. Shape design, easy to achieve spindle positioning, is an ideal structure in the high-speed spindle unit. As the most important part of high-speed CNC machine tools, the performance of the spindle is largely determined by the high-speed machine tool’s machining accuracy and production efficiency. However, the models of electric spindles vary and their effects are also different. Therefore, the reasonable choice of electric spindle is particularly important. For this reason, the Star Wheel will explain the points of attention for selecting the electric spindle.
1. There are two types of spindles: constant torque and constant power. The constant power is more expensive. The spindle of the engraving machine adopts a constant torque.
2. The types are air-cooled and water-cooled. The air-cooling is mainly a small power spindle with several hundred watts in the early stage. Now the water-cooled electric spindles are basically used on engraving machines, and the power is low and noise is small.
3. Lubrication methods include oil mist and grease. High-speed electric spindles with a speed of over 24,000 rpm adopt oil mist, which is supplied by a dedicated oil circuit, and is complicated to install and use. The engraving machine is mostly grease-lubricated, and the rotation speed can be adjusted around 6000-24000 rpm. speed.

Motor spindle purchase knowledge points:
1 There are two characteristics of electric spindle: switch cabinet and constant power. The constant power is more expensive, and the spindle of the engraving machine is suitable for constant torque.
2. cooled method is 2 types is air-cooled and water-cooled, and air-cooled is mainly a low-power spindle that wakes up several hundred watts. Now, the engraving machine is basically a water-cooled electric spindle, with low power and noise.
3.  Lubrication methods include oil mist and grease. High-speed electric spindles of over 24,000 rpm use oil mist, which is supplied by a dedicated oil circuit. In accordance with the complicated use, the engraving machine is mostly grease-lubricated, and the rotation speed can be around 6,000-24,000 rpm.
4 support methods are 2 bearings, 3 bearings and 4 bearings, 3, 4 bearings are suitable for engraving heavy loads such as steel, more than 1.5KW spindles are used, general soft metal with 2 bearings enough.
5 Spindle The core frame is made of aluminum alloy and stainless steel. At present, most of the spindle cores are made of aluminum alloy. They are lightweight, but they are bulky. Now there are some new products that use stainless steel core holders, and the spindle size can be reduced with copper power. Milk is usually 1.5KW spindle volume is about 80 × 215mm, stainless steel welding core spindle new products can do ~ 65 × 210mm or so, more suitable for engraving machine use, but the price of about one hundred or two hundred.
6 Select the inverter power to be larger than the spindle power. This can give full play to the output power of the spindle. The 1.2KW spindle is equipped with a 1.5KW inverter. 1.5KW spindle with 2.2KW frequency converter. Personally, I hope to help you,
In fact, this should be practiced by you yourself, because the shoes are worn on the feet. As far as the joints are not suitable, only the feet know. The following is the selection of the electric spindles. I hope you can get a little help. DECI spindle motor wishes you the best you want.
