1. In the past, the production of molds was mostly manual, and it was necessary to use plaster to make a model, and then use a billet to make a model. Plane and grind it with a planer, and then use a hand or engraving machine to carve the shape of the product mold from the template. The whole processing process requires high skills of the processing master, and it is quite time-consuming. The machining center can complete a variety of processes at one time, and the processing efficiency is unmatched by manual operations. Before processing, use computer to design graphics, simulate and test whether the processed workpiece meets the requirements, and adjust the test piece in time, which greatly improves the fault tolerance rate and reduces the error rate. It can be said that the machining center is the most suitable mechanical equipment for mold processing.
2. Box-shaped parts
Parts with complex shape, cavity inside, large volume and more than one hole system, and the length, width and height of the internal cavity with a certain proportion are suitable for CNC machining of the machining center.
3. Complex surfaces
The machining center can be clamped at one time to complete the processing of all sides and top surfaces except the clamping surface. The processing principle is different for different models. The spindle or worktable can complete the 90° rotation with the workpiece. Therefore, the machining center is suitable for processing mobile phone parts, auto parts, and aerospace materials. Such as the back cover of the mobile phone, the shape of the engine and so on.
4. Special-shaped parts
The machining center can be assembled and clamped, and can complete various processes such as drilling, milling, boring, expanding, reaming, and rigid tapping. For special-shaped parts with irregular shapes that require mixed processing of points, lines and surfaces, the machining center is the most suitable mechanical equipment.
5. Discs, sets and plate parts
According to different main shaft transportation methods, the machining center has a distributed hole system with a keyway, radial hole or end face, a disk sleeve or shaft parts with a curved surface, such as a shaft sleeve with a flange, and a shaft part with a keyway or square head. Wait. There are also plate parts with more hole processing, such as various motor covers. Vertical machining centers should be selected for disc parts with distributed holes and curved surfaces on the end faces, and horizontal machining centers with radial holes.
6. Periodic mass-produced parts
The processing time of the machining center generally includes two parts, one is the processing time, and the other is the processing preparation time. The preparation time accounts for a high proportion of them. This includes: process time, programming time, part trial time, etc. Machining centers can store these operations for repeated use later. This saves that time when machining the part later. The production cycle can be greatly shortened. It is therefore particularly suitable for mass production of orders.
