With the continuous development of CMM, scanner and laser tracker technology, the mold is also developing rapidly. Next, we will introduce how to improve the performance of mold processing, and what is the embodiment of performance improvement?

1、 Improve mold processing performance

The main function of CMM is to collect coordinate data by non-contact means such as contact or laser scanning. After data processing, the workpiece under test is reconstructed. Modern measurement technology is constantly integrated into product research and development, In the system of reverse engineering design and manufacturing, the inseparable relationship between mold and mold part design and manufacturing is more obvious. Nowadays, mold enterprises take mold as the carrier, actively explore the production of mold parts has become an important mode of production, mold enterprises purchase parts equipment demand is strong. In 2007, China produced 173000 molding equipment, including 3000 CNC molding equipment; It is understood that the sales of cutting tools in the world are more than 10 billion US dollars, and the three markets of Europe, North America, Japan and Australia with developed industries account for 75% - 80%. In Asia, China is also an important market, The share of traditional high-speed steel cutting tools has dropped to less than 30%. China's machinery manufacturing industry, which has participated in the global competition, is increasingly seeking for efficiency. Mold enterprises are also increasingly in need of modern high-efficiency cutting tools with high precision, high efficiency, high reliability and specificity, Cemented carbide tools and ceramic tools are widely used in die and mold enterprises. According to the rough estimation of experts, the demand for cutting tools in China is more than 8 billion yuan. Among them, the consumption of modern tools with high precision, high efficiency and high reliability, such as cemented carbide and ceramics, is about 1.5 billion yuan, of which 80% - 85% are imported, More than 90% of the cutting tools used in mould manufacturing are imported. The complexity and precision of the mould require the quality of the cutting tools to be better.

2、 Mold processing equipment needs to improve the processing performance, mainly reflected in:

The first mock exam is the first mock exam. 1, the increasing size of the mold parts and the high productivity of the parts require a multi cavity mold, which results in the larger mould. The large tonnage of the large mold can reach 100 tons, a mold with hundreds of chambers and thousands of chambers. It requires large worktables for the die processing equipment, Y axis Z stroke, heavy bearing, high rigidity and high consistency.

2. The hardness of die steel is high, which requires the die processing equipment to have thermal stability and high reliability

3. For the complex cavity and multi-functional composite die, with the complexity of the product shape, it is necessary to improve the design and manufacturing level of the die. The multi-functional composite die with various grooves and materials formed or assembled into components in a set of die requires large amount of programming program, comprehensive cutting ability and high stability of high and deep hole cavity, which improves the machining difficulty

4. High speed milling has many advantages, such as machining high hard steel, stable processing, small cutting force, small temperature deformation of workpiece, etc., which makes mold enterprises pay more attention to high-speed machining

5. High dynamic accuracy. The static performance (such as repeated positioning accuracy and linear feed rate) introduced by machine tool manufacturers can not reflect the actual processing situation when the mold 3D surface is machined. The high-precision machining of 3D surface of the mold puts forward the requirements of high dynamic precision performance, High speed and high precision can only be realized with the combination of high rigidity, thermal stability, high reliability and high quality control system

6. The combination of processing technology and green product technology will be taken into consideration when enterprises purchase equipment. The radiation of EDM machine tools and the selection of medium will be the factors affecting safety and steel. The electro thermal steel milling technology will be developed in the field of mold processing in the future

7. The composite application of multiple measurement technology, high speed measurement and reverse engineering become the development direction of mold participating in product development and design technology

The improvement and creation of high and new technology is necessary and must be done in any industry, because only by improving technology can we own a piece of land in the inner circle of the industry, and China's mold industry is working towards this direction
