A double-column CNC vertical lathe is a CNC lathe with two column support structures. It uses a vertical spindle for processing and is equipped with support columns on both sides to increase the stability and rigidity of the entire machine.
Hydraulic chuck is a device used to clamp workpieces. It uses the pressure generated by the hydraulic system to achieve the function of clamping workpieces. Compared with traditional mechanical chucks, hydraulic chucks have the advantages of large clamping force, adjustable clamping force, and easy operation.
Low noise is one of the important considerations in modern machine tool design. In order to reduce the generation and transmission of noise, machine tool manufacturers usually take the following measures:

1. Structural design: Use reasonable structural design, including vibration-absorbing supports, sound-absorbing materials, isolation devices, etc., to reduce machine tool vibration and noise transmission.
2. Acoustic control: Use sound insulation materials, sound-absorbing materials, etc. in key parts of the machine tool to absorb and reduce the transmission and reflection of noise.
3. Control system optimization: Optimize the parameter settings and control algorithms of the CNC system to reduce noise generation and machine tool vibration.

In summary, double-column CNC vertical lathes equipped with hydraulic chucks can provide better processing stability and clamping effects, and can achieve low-noise operation through measures such as structural design and acoustic control. However, the specific design and performance characteristics need to be understood and confirmed in detail based on the specific machine model and manufacturer. When selecting and purchasing machine tools, it is recommended to communicate with a professional machine tool manufacturer to ensure that you get equipment suitable for your needs.
