As an efficient and precise machine tool equipment, CNC machining center plays an important role in modern manufacturing industry. In order to ensure the long-term stability and reliability of the machine tool, the design of the body and the spindle unit of the CNC machining center are of key significance.

In order to reduce the vibration of the heavy cutting machine, the CNC machining center usually adopts a large box base structure. The design and material selection of the base of the large box can effectively reduce the vibration of the fuselage, improve the stability of the machine tool, and reduce the vibration amplitude of the machine tool during high-speed cutting, thus improving the processing accuracy and surface quality.

Spindle unit is the core component of CNC machining center, and its performance has a direct impact on the stability and machining quality of the machine tool. In order to ensure the long-term stability of the machine tool, the spindle unit needs to have the characteristics of precision, high speed, high precision and high rigidity.

The high speed performance of spindle unit is one of the important indexes to ensure the machining efficiency. By using high-precision bearings and rigid structural design, high-speed operation of the spindle unit can be achieved. The smooth operation of the high-speed spindle can reduce the vibration of the machine tool and improve the processing quality and efficiency. By using high-precision bearings, precision machining technology and high-precision assembly and debugging, the radial and axial runout of the spindle can be reduced and the machining accuracy can be improved. At the same time, the reasonable lubrication system and temperature control technology can also reduce the error caused by the thermal expansion of the spindle to ensure the stability and consistency of the processing.

The high rigidity of the spindle unit can effectively suppress the vibration of the machine tool, improve the cutting stability and surface quality, and maintain the stability of the machining process.

The life of the spindle unit and noise levels are also important considerations. The long-life spindle unit reduces machine maintenance frequency and downtime, increasing machine availability and productivity. The low noise spindle unit can reduce the noise pollution of the working environment and provide a good working environment and operating experience.
