Vertical lathe quality appraisal

Vertical lathe, also known as vertical turning machine, is a common metal processing tool. Its basic structure consists of a bed, spindle, cutting tool holder, feeding mechanism and other parts. Among them, the bed is the foundation of the entire lathe, carrying the installation and movement of various components. The spindle is a long shaft with bearings mounted on the bed. One end is connected to the motor and the other end has a chuck, which can be used to install cutting tools and machined parts. The cutting tool holder is the main component used to hold cutting tools. The feed mechanism is a component used to control the movement and processing depth of the cutting tool on the workpiece.
vertical lathe is suitable for processing cylindrical and conical parts with smaller diameters, such as iron, copper, aluminum and non-ferrous metals. It is mainly used for turning shaft workpieces with a diameter of less than 200 mm, and can process workpieces such as outer contours, end faces, and holes. In addition, vertical lathes are often used to process plastic, rubber and other material products, as well as workpieces such as molds and prototypes.
In the case of vertical lathe quality appraisal, Zhongke Testing can provide vertical lathe quality appraisal services.

Vertical lathes are divided into single column type and double column type. The processing diameter of single-column vertical lathes is smaller, and the maximum processing diameter is generally less than 1600mm. The processing diameter of double-column vertical lathes is larger, and the processing diameter of the largest vertical lathe exceeds 25000mm.

A machinery company introduced several new vertical lathes and placed them in the workshop. However, during subsequent use, the machine tools frequently experienced oil leakage, abnormal noise and other problems. The equipment manufacturer ignored various problems. In desperation, the case was brought to the local court.
was entrusted by the court to conduct technical appraisal of the "vertical lathe" involved in the case. Appraisal analysis results: The
appraisal expert group discussed and comprehensively analyzed the relevant information, on-site investigation and inspection results of the "vertical lathe" involved in the case, and made the following appraisal opinion: The processing heights of the side tool table and vertical tool table of the
vertical lathe are approximately 1217mm and 1170mm respectively, which do not meet the technical parameter requirements stipulated in the contract.
