HQD GDK125-18-24Z/5.5 5.5kW Metalwork Electric Spindle Motor For CNC Automation Machines

1. Target Applications and Highlights

HQD Electric Spindle Motor GDK125-18-24Z/5.5 is very well-known and widely used in Stone work 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.

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.

The main performance characteristics and advantages of the electric spindle are as the followings:

High speed:

The speed of the electric spindle is up to 60,000rpm, which can meet the requirement of various materials processing.

High precision:

Electric spindle can achieve micron-level high precision processing.

High rigidity:

It has the characteristics of high torque and high rigidity and can withstand high frequency processing.

High reliability:

Using high quality ceramic balls bearings and electronic components to improve the reliability and lifetime of the electric spindle, also reduce the heating.

Low noise:

The noise of the electric spindle is small, running smoothly, and can meet the requirements of ultra-precision processing.

High security:

The electric spindle has a variety of protection functions, such as overload protection, overcurrent protection, etc., and also protect the machine and operators.

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.
