GDK125-12-18Z/7.5 Water-cooling 7.5kW Electric Spindle Motor for CNC Machines and Industrial Automations
Target Applications and Highlights
HQD Electric Spindle Motor GDK125-12-18Z/7.5 is very well-known and widely used in Stonework,woodwork CNC machines etc., such as cutting, carving, engraving etc. One of the best stonework spindles made in China.
Application of electric spindles:
1. Machinery processing
In the processing of machine tools, the electric spindles can achieve high speed and high precision cutting, milling, and drilling. It can adjust the speed as needed to meet the processing requirements of different workpieces and materials.
2. CNC system
In the CNC system, the electric spindle is one of the key equipment for automation processing. It can control the speed and progress through CNC programs to achieve high quality automated production. The high-speed, high-precision and high efficiency of the electric spindle can improve processing performance greatly.
3. Other industrial fields
In addition to machine tools and CNC systems, electrical main shafts are also widely used in other industrial fields, such as automobile manufacturing, aerospace, mold manufacturing, etc. Its applications in these areas are mainly to complete specific processing tasks, such as car cutting surfaces and hole processing.

The electric spindle is a spindle driven by a motor, and it has the characteristics of high speed, high accuracy, high rigidity and high efficiency etc. It is widely used industrial automation, such as machine tools, CNC systems, and other applications.
The electric spindle is a product that integrates the spindle with motor. Compared with regular spindle, the length of the transmission chain is shortened to zero, realizing the "zero transmission“, which enables more flexibility in machine design. The electric spindle is also called ELECTRO SPINDLE, MOTOR Spindle, or Motorized Spindle, High-frequency spindle, Direct Drive Spindle etc.
Technical characteristics of electric spindle bearings.
Rolling bearing is the most widely used bearing for electric spindles in the market.
Because the maximum speed of the electric spindle depends on the function, size, structure and lubrication method of the bearings, the bearing must have the advantages of high speed performance, high dynamic load capacity, good lubrication performance, and small heating etc. Electric spindles mainly use rolling bearing, sliding bearing.
At present, the most widely used bearing in the market is the rolling bearing of ceramic balls. This is mainly because the ceramics have the advantages of small density, good rigidity, and small thermal expansion coefficients. The sliding bearing is larger in heating, so not widely used.
