woodworking cnc router spindle introduction
woodworking cnc router spindle introduction.
Wood carving industry in China is a traditional industry, timber supply chain will be a long time! In this case, wood carving industry is to conduct a major change, the old wood carving talent retirement, the younger generation of high efficiency, mechanization and automation requirements, making wood engraving equipment come into play! The spindle motor is an important component of woodworking engraving machine, woodworking engraving machine is working power source. Changsha new leaves NC to introduce you to the basics of the spindle motor
The basic situation a spindle motor
A general sense of the spindle motor, also known as high-speed motor, that the number of revolutions over 10,000 rpm / min AC motor. Mainly used in wood, aluminum, stone, metal, glass, PVC and other industries, it has fast speed, small size, lightweight, low cost materials, low noise, and low vibration, more and more attention and application of related industries .
In the modern society of rapid technological progress, due to the wide range of applications spindle motor, coupled with its meticulous workmanship, fast processing speed and high quality motor makes engraving spindle motor industry's favor by playing a more and more in wood engraving process important role.
And now the market appears spindle is a machine tool spindle and the spindle motor integration of new technologies, is a major feature of CNC engraving machine. It uses a mechanical and electrical integration of new technologies, new processes, new materials, with a frequency variable speed, low noise, smooth operation, reliable and good load characteristics. For high-speed drilling milling and engraving machines
Spindle motor specifications have 1.5KW / 2.2Kw / 3.0KW / 4.5KW, etc., such as water-cooled spindle motor 1.5KW
Spindle motor Material: 304 stainless steel jacket, water jacket for high aluminum, high temperature copper coil.
Voltage: 220V and 380V (inverter output must not direct the use of ordinary household electricity)
Current: 4A
Speed: 0-24000 rev / min
Frequency: 400Hz
Torque: 0.8Nm (Newton meters)
Radial runout: 0.01mm or less
Concentricity: 0.0025mm
Weight: Net weight 4.08 kg
Nut Model: ER11 or ER11-B type type two kinds of nuts chuck, random delivery
Speed mode: through the inverter to adjust the output voltage and operating frequency, variable speed can be achieved 0-24000
Cooling: water circulation or light oil circulation cooling, air-cooled three ways.
Dimensions: Diameter 80mm
Features: Motor torque, low noise, smooth speed, high-frequency, variable speed, no-load current is small, slow heating, cooling fast, easy to use, long life.
2, the type of spindle motor
(1) spindle motor can be divided into air-cooled and water-cooled spindle motor spindle.
(2) air-cooled spindle: The price is higher than the cost of water-cooled spindle, mainly used in woodworking engraving machine, in northeast China more suitable, because it is too cold in winter water-cooled spindle easily freeze, frozen pipes, air-cooled spindle does not make engraving machine users have this kind of trouble. Good quality air-cooled main spindle motor mainly imported.
(3) water-cooled spindle: spindle use of this relatively common in the domestic advertising engraving machine, woodworking engraving machine, jade and stone engraving machine engraving machine, tombstone engraving machine, mainly because of the relatively modest cost of such spindle can be suitable for the majority of domestic production strong corporate and stability, the technology is mature, corrupted rate is not very high.
(4) (b) of the air-cooled and water-cooled spindle motor spindle differences and connections
When customers in the selection of the spindle motor will think: in the end is a good air-cooled, water-cooled good? So figuring out the difference between both contact necessary.
(5) air-cooled and water-cooled spindle motor spindle in common:
On the internal structure, the two are unified, and are based on the rotation of the electron around the coil; from the control of the motor, the water-cooled basically adopts frequency control, and air cooling can be used without frequency conversion and two ways.
(6) air-cooled and water-cooled spindle motor spindle difference:
(7) Water is used to cool the water circulating heat generated by the spindle rotation to tell. This effect is better, because the temperature of the water flow is generally produced not more than 40 degrees; air-cooled main ways to use fan cooling, the effect is certainly not as good as water cooling;
(8) the noise, the water-cooled basically no noise, and air-cooled noise will be significantly more.
(9) on life, the water-cooled usually pay attention to maintenance, frequently changes the water, or the use of industrial water cooling machine, life much longer than the air-cooled.
(10) accuracy, the water-cooled spindle axial and radial runout basically in the 0.003 mm or less, more than the precision of the air-cooled.
3 spindle motor brands and major models
(1) Brand: With the development of science and technology, technological innovation is also changing the motor. Now the motor on the market is divided into domestic brands and foreign brands
(2) foreign brands are: Japan's Mitsubishi, Yaskawa, Sanyo, Panasonic and Fuji, Siemens, Germany SCHORCH (Germany Xiao Chi) motor, the United States GROSCHOPP motor, Switzerland
(3) domestic brands are: Jiamusi Electric, Xiangtan Electric, Johnson Electric in Hong Kong, Shanghai Electric, Harbin Electric; Nanyang Motor, Shanghai Nanyang Electric, Changzhou Polaris appliances, water-cooled spindle motor prosperity in the engraving machine used widely.
(4) In the past quite a long time, China's motor is mainly dependent on foreign brands. And after a lot of effort, domestic motor has been rapid development in the motor market also win a place.
