GDK125-12-18Z/7.5 Water-cooling 7.5kW Electric Spindle Motor for CNC Machines and
Industrial Automations
1. Products Overview
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.

6. Background Knowledge
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.
