Machining centers are often divided into vertical machining centers, horizontal machining centers, and gantry machining centers according to the state of the spindle in the space. After the workpiece is clamped once, it can complete the processing of all sides and top surfaces except the mounting surface. Common universal machining centers are as follows: 1 The spindle can rotate 90°, which can work like a vertical machining center or a horizontal machining center. 2 The spindle does not change its direction, and the worktable rotates 90° with the workpiece. Finish the processing of five sides.
(1) Box-type parts: Box-type parts generally refer to parts that have more than one hole system, a cavity inside, and a certain proportion of length, width, and height.
(2) Complex curved surface: It is difficult or even impossible to complete a complex curved surface using ordinary machining methods.
(3) Special-shaped parts: Special-shaped parts are parts with irregular shapes, and most of them require point, line, and surface multi-station mixed processing. Such as fork and so on.
(4) Discs, sleeves, and plate parts: disc sleeves or shaft parts with key grooves or radial holes or distributed holes on the end surface, curved disc sleeves or shaft parts, such as flanged shaft sleeves, key grooves, or square head shafts Type parts, etc., as well as plate parts with more porous processing, such as various motor covers. Disc parts with distributed holes and curved surfaces on the end surface should choose a vertical machining center, and a horizontal machining center with radial holes should be selected.
(5) Periodically put into production parts: when machining parts with a machining center, the required time mainly includes basic time and preparation time, of which preparation time accounts for a large proportion, such as process preparation, programming, first part trial cutting, etc. These times are very long, and the processing center can be used to store the contents of these times for repeated use in the future. In this way, this time can be saved when processing the part in the future. The production cycle can be greatly shortened.
