Machining center, do you really understand? Dry goods!
Machining centers are often divided into vertical machining centers, horizontal machining centers, gantry machining centers and universal machining centers according to the state of the spindle in space. The machining center whose spindle is vertical in space is called vertical machining center, while the spindle is horizontal in space is called horizontal machining center.
(1) Basic components. It is the basic structure of machining center, which is composed of lathe bed, upright post and workbench, etc. They mainly bear the static load of machining center and the cutting load generated during machining, so they must have enough rigidity. These large pieces can be iron castings or welded steel structures, which are the largest parts in the machining center in volume and weight. AKIRA-SEIKI castings are made of high-grade Mihanna castings, which have high stability after heat treatment.
(2) Spindle components. It is composed of spindle box, spindle motor, spindle and spindle bearing. The start, stop and speed change of the spindle are controlled by the numerical control system. For more numerical control knowledge, WeChat searches WeChat official account's "Numerical Control Programming Teaching" to receive a free tutorial, and participates in the cutting movement through the cutter mounted on the spindle, which is the power output component of cutting. It is the key component of the machining center, which determines the machining accuracy and stability of the machining center.
(3) Numerical control system. The numerical control part of the machining center is composed of cNc device, PLC, servo drive device and operation panel.
(4) Automatic tool changing system. It consists of tool magazine, manipulator driving mechanism and other parts. When the tool needs to be changed, the numerical control system gives instructions, and the manipulator (or by other means) takes the tool out of the tool magazine and loads it into the spindle hole. It solves the task of automatic storage, selection, transportation and exchange of tools between processes in multi-process continuous processing after the workpiece is clamped once.
