High-speed spindle components are one of the most critical
components of high-speed machine tools, and high-speed spindle
units are one of the key technologies for high-speed machining. The
types of high-speed spindle units mainly include electric spindles,
pneumatic spindles, and hydrodynamic spindles. Different types of
spindle output powers differ greatly. The high-speed spindle needs
to complete the lifting speed in a very short time and quickly stop
at the specified position, which requires the spindle to have a
high angular acceleration. If the drive of the main shaft passes
through the intermediate link such as the belt drive, it will not
only slip at high speed, generate vibration and noise, but also
increase the moment of inertia. It is very difficult to quickly
stop the machine spindle. The high-speed machining machine spindle
system is almost always in the form of an integrated structure
driven directly by an AC servo motor. The integrated spindle has
two forms: one is to directly connect the motor to the main shaft
through the coupling, and the other is to integrate the rotor and
the main shaft of the motor.
High-speed machine tools must have both a high-speed spindle system
and a high-speed feed system, not only to increase productivity,
but also to achieve the normal working conditions of the tool
during high-speed cutting, otherwise it will cause sharp wear of
the tool and damage the surface quality of the machined workpiece.
The feed system only makes sense to achieve high speed in a short
period of time and to achieve a quasi-stop in a short period of
time. In order to achieve high-speed feed, in addition to the
improved ball screw pair, linear motor drive has become the
development direction of high-speed feed systems.
High speed CNC control system
High-speed machining machine spindle speed, feed speed and feed
acceleration and deceleration are very high, so higher requirements
are imposed on the control system of high-speed machining machines.
CNC devices for high-speed cutting must have high calculation speed
and accuracy. Fast response servo control to meet the high speed
machining requirements of complex cavities.
CNC high speed machine body
In order to ensure the high precision, high stability and high
rigidity of the machine tool, all castings should be finite element
analysis to optimize the design, high-quality cast iron with high
damping performance, all subjected to vibration aging treatment.
The high-speed milling of the hardened die steel can be directly
performed, and the surface processing speed is fast and the quality
is good, the process flow of the mold processing is greatly
shortened, and the production efficiency is improved. The main
components such as the bed and the integrated beam retain the sand
core to make the machine's vibration resistance better.
