CNC vertical lathe is referred to as CNC vertical lathe for short. Its lathe spindle is perpendicular to the horizontal plane and a circular worktable with large diameter is used to clamp workpieces. This kind of machine tool is mainly used to process large and complex parts with large radial size and relatively small axial size. What are the characteristics of CNC vertical lathe?
The vertical lathe adopts the trinity of machine, electricity and liquid, and is designed according to the pleasant layout of ergonomics, with compact structure, saving area, simple operation and convenient maintenance. The base is an integral high rigid cast iron structure, with smooth chip removal and reasonable cutting space.
The vertical lathe bed guide rail adopts rectangular guide rail structure. After high-frequency quenching, the contact surface with its corresponding sliding plate is plastic coated guide rail, which can reduce the friction resistance when the guide rail slides and has good dynamic characteristics. The sliding plate and beam adopt rectangular guide rail structure and are pasted with plastic.
The main shaft adopts P5 grade bearing and is subject to precise dynamic balance. The bearing is lubricated with grease to ensure the high-speed and smooth rotation of the main shaft and reduce the thermal deformation to a minimum. The vertical and horizontal movements of the NC vertical lathe are directly connected with the lead screw and AC servo motor, and the lead screw bearing adopts angular contact bearing to ensure the transmission accuracy. The clamping and positioning of the tailstock is realized by two screws on the side driving the clamping block. Lock the nut on the twin screw, and the screw drives the clamping block to rise to fix the tailstock on the bed.
2、 What does CNC vertical lathe bring
As the strategic equipment of national defense and military industry, CNC vertical lathe is an important manufacturing means of various weapons and equipment and an important guarantee for the modernization of national defense and military equipment. Many times, CNC machine tools are also called "machining centers". Since its emergence, CNC machine tools have brought revolutionary changes to the machinery manufacturing industry.
CNC vertical lathe has high production efficiency. It can not only save the work of scribing and intermediate inspection, but also save the complex tooling and reduce the relatively complex and cumbersome work such as the installation and adjustment of machined parts and multiple tool setting due to its automatic tool change function. The machining center can select better process lines and cutting parameters, effectively reduce the auxiliary time in machining, so as to improve the production efficiency.
CNC vertical lathe has high machining accuracy and stable machining quality. The automatic tool change function of the machining center can effectively reduce the clamping times of the workpiece, reduce or eliminate the positioning error caused by multiple clamping, and improve the machining accuracy.
When the position accuracy of each part is required to be high, the automatic tool change function of the machining center can easily and effectively reduce the positioning and tool setting error, complete the processing of each part in the process of one-time clamping and one-time tool setting, and ensure the position accuracy requirements of each processing part.
