Surface. Precision mold components of the processing outside surface is easier than the internal surface, the surface of the rule is easier to processing than the irregular surface, the processing hole is easier than the die space.
Precision. The higher the accuracy of precision mold parts, the more difficult it is to make. The relative position accuracy depends on the equipment, measurement, repair mould manufacturing precision and forming part of the guarantee. Other parts of the position accuracy can be guaranteed by the same method, and can reduce the cost.
Surface roughness. Precision mold parts surface roughness on the mold is very important, the manufacturing time is more. Increasing the surface decoration is bound to increase the manufacturing process, but sometimes can reduce the surface roughness requirements.
Number of holes and cavities. Precision mold components hole and the cavity of the increase in the number, no doubt to the higher requirements for mold manufacturing factory and position (especially the relative position of the requirements, increase the complexity and difficulty in manufacture of mold.
Heat treatment. The heat treatment of precision mould parts not only needs to meet the user requirements for mold life, but also affect the manufacturing efficiency of the process.
Automatic tool change and automatic tool setting for tool magazine of precision CNC machining center:
Precision CNC machining is to complete a variety of processes in the automatic state of CNC equipment, mainly for some fixed mass production operations. But for the mold industry and small batch production units, do not always go to the machining center, many manufacturers buy machining center when CNC milling to use.
It is very simple to use the tool magazine for the cost of the CNC system, but the spindle and tool magazine, air compressor and various tool handles will increase the cost, and the programming and adjustment of the tool magazine also need to spend the corresponding time. Therefore, for less than one or two hundred workpieces of the same variety, the machining center should not be used as far as possible, which has high cost and low efficiency.
Automatic tool setting system can be used for precision CNC machining. The tool is loaded up one time and one button is used. The machine tool can automatically adjust the tool and process directly. The error is within 0.001 ~ 0.0003 mm, which is not much slower than the automatic change time. If it is a machining center, the efficiency of the machine tool without automatic tool setting device is much higher than that of the machine tool without tool magazine but with automatic tool setting device.
For the domestic manufacturing industry, especially for mold manufacturing enterprises, it is generally single piece production, and labor resources are sufficient. Therefore, for the processing of small batch industrial parts, we should fully consider the use value of funds, and do not use machining center equipment. What’s more, there are still many problems in the tool magazine of domestic manufacturers.
