GDF60-18Z/7.5 Air-cooling 7.5kW Electric Spindle Motor for CNC Machines and Industrial Automations
HQD Electric Spindle Motor GDF60-18Z/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.
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.
Advantages of electric spindles
High-speed Processing
The main shaft has the ability to rotate high -speed rotation, which can achieve high -speed and efficient processing. Compared with the traditional hydraulic or pneumatic spindle, the speed control of the electrical axis is more accurate and the speed range is wider;
High-precision Processing
The main shaft has high precision processing capabilities and can achieve micron -level processing accuracy. Its speed control is accurate and can meet the processing tasks with higher accuracy requirements;
High Rigidity
The main shaft of the electricity has high rigidity and can withstand large loads. Its structure is compact, the transmission is simple, and it can effectively resist the cutting force and vibration;
Energy Saving and Environmental Protection
Compared with the traditional hydraulic or pneumatic spindle, the electrical axis has lower energy consumption and less emissions. The main shaft of the electrical shaft can be optimized by energy consumption through the speed control of the motor and reduce the waste of energy.

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.
