This blog analyzes the particularity of mold processing and then puts forward some requirements for the performance of CNC machining center machine tools given this particularity, hoping to play a reference role for buyers.

Compared with another machining, mold processing has certain particularity, which mainly includes:

 

  1. Most molds need to process complex spatial curved surfaces on solid core metal modules. With the continuous development of molds to large-scale, the weight of modules will become larger and larger, and now some have reached dozens of tons;

 

  1. Most molds are cuboid or cube in shape, few of which are narrow and long, and the main processing volume is concentrated on concave and convex molds;

 

  1. As the requirements of mold products become more and more precise and complex, the requirements for mold processing accuracy are also higher and higher. Now the processing accuracy of many molds has reached ± 1~2 μ m. It will soon develop to less than ± 1 μ m;

 

  1. As users' requirements for the mold production cycle become shorter and shorter, mold processing must meet the requirements of high efficiency, fast, certain flexibility, and long-term full load non-stop operation.

 

According to the above four particularities, the following basic requirements are put forward for CNC machining center machine tools for mold processing:

 

Compared with other mechanical processing, mold processing has the characteristics of high precision and complex processing. The processing accuracy of many molds has reached ± 1~2 μ m. With the continuous improvement of the production cycle and efficiency of mold processing, some basic requirements are put forward for mold processing equipment:

 

  1. The machine tool should have good rigidity and a large bearing capacity suitable for the weight of the module;

 

  1. The size of the worktable should be compatible with the overall size of the mold, which is suitable for rectangles, squares and circle, not narrow and long, while the height direction and stroke require a large space;

 

  1. High accuracy and accuracy retention;

 

  1. The allowance shall be removed quickly and efficiently with high reliability to maintain continuous and long-term full load operation;

 

  1. To adapt to complex spatial surface processing and have a large amount of processing capacity, the machine tool is required to be able to multi-axis linkage and equipped with a CNC system with large information capacity.

 

  1. According to the different processed parts, some need to add four axes and five axes.

 

Selection principle and program of mold CNC Machining Center

 

The initial investment and maintenance of a CNC machining center are expensive and require high-quality management and operators. Users should choose according to their own economic and technical strengths and on the premise of meeting their needs.

 

  1. Determine the shape and size of a typical machining workpiece

 

According to the positioning of the enterprise in the mold, the market Determines the type, structure, shape, and size range of mold production Then uses group technology to classify the typical templates and then select the appropriate NC machining center.

 

  1. Machine tool Market Research and ordering

 

There are many kinds of CNC machining centers, which are expensive. The selection of a machining center is not only a comprehensive application technology based on CNC machine tool technology and processing technology but also a comprehensive management technology constrained by its economic strength and technical strength. After the technical scheme for the primary selection of the machining center is issued, compare the goods with three companies, communicate with the machine tool manufacturer in-depth, ask and investigate the typical users provided by the machine tool manufacturer, take into account the immediate needs and long-term planning, and finally determine the model and manufacturer of the machining center with the best performance-price ratio in combination with the user's CAM programming ability, NC machine tool operation, management, and maintenance level.

 

Make a purchase of small horizontal machining center, over machining center, 5 axis gantry type machining center from China, you can get them at a good price if you have a large quantity. We hope to be your long-term partner.
