The use of high-speed processing technology mold, in addition to high quality processing products, but also can significantly reduce and even cancel the inefficient grinding and artificial working hours, the overall shorten the mold manufacturing cycle. In order to meet the market demand, the development schedule of new products is getting shorter and shorter, and only the products can be quickly introduced to the market to seize the opportunities (business opportunities). For example, the delivery of mobile phone molds, the traditional process of market demand, design and development, manufacturing and processing, test mode and product launching have been compressed from 45 days to 30 days or even 14 days. Under such circumstances, from R & D, manufacturing to delivery, traditional manufacturing and processing technologies have failed to meet market demand. In other words, "speed" and "quality" in the 21st century will determine who is the winner in the market. Therefore, production equipment, peripherals, production technology, machining tools, CAD / CAM / CAE software must be high-speed high-precision and high efficiency. The machine can meet the high-speed cutting, in general, can be divided into the following requirements: 1. Machine design for high-speed operation of high-speed operation of the machine first requires its institutions with high rigidity, to absorb high-frequency vibration and high inertial G value to To ensure high-speed cutting precision and stability. Spindle speed has now reached a very high degree, which requires high-speed spindle lubrication and cooling system to have to meet the short and thin principle. As one of the high-speed processing of the implementing agencies, high-speed feed institutions require to meet the high-feed acceleration and deceleration, at the same time must achieve high precision. Therefore, the servo motor and ball screw without backlash and LOSSMOTION phenomenon of the actual transmission, can only show the effect of high feed cutting; ball screw mechanism design should also ensure that the positioning accuracy and prevent thermal deformation error; The Z axis requires lightweight, because the Z axis up and down the reaction must be sensitive and there will be no interference jitter phenomenon, at the same time require a special electronic control circuit design, so that the Z axis even in the case of instantaneous power failure will not fall, causing the tool Broken knife. Die processing are generally a long time processing, so long-term high frequency inverter spindle heat rise, it is easy to cause the aging of electronic components, so the electronic control box to be closed air-conditioning system, to ensure the life of parts and stability of the box , And prevent oil from entering. 2. Excellent CNC control system CNC numerical control system is issued a position command unit, requiring instructions can be passed accurately and quickly, after processing the position of each axis command issued by the servo system must be in accordance with the instructions quickly drive the tool or table Exact movement. It requires the ability to process blocks quickly, minimize their machining errors, and more. In high-speed processing applications, Siemens 840D and Fanuc18iMB the most representative. 3. Suitable for high-speed operation of the tool holder and cutting tools for high-speed cutting, especially high-speed rotary tool, to ensure machining accuracy and operational safety considerations, require tools and shanks have better quality and performance. For knives, slender than less than 10 times better. There are tungsten carbide knives, CBN knives and tungsten carbide cutting tools. As for the shank, it requires dynamic balance less than 2.5G, HSK, BBT (BTF-B) and some special shank will be able to meet the above requirements. 4. Professional CAD / CAM Software Professional CAD / CAM software requires precise path calculation method, in addition to accurately meet the accuracy requirements of 3DProfile, but also to achieve more to reduce the discharge process, or even without polishing can reach the surface Quality requirements. It must be able to produce a good cutting path, the amount of cutting stable, not only to improve processing efficiency, but also to extend tool life and save tool costs. Due to the diversification of design software, it needs to have good transcription compatibility with other softwares, and can easily take pictures transferred from other softwares without distortion even with small holes or sections 2D, 3DCAD quick fix for users to live loopholes, control aging. In terms of practicability, specialized CAD / CAM software requires the capability of self-curved CAD, understanding of workpiece features and priorities prior to NC machining, and the ability to optimally simulate cutting. At the same time, it can also simulate the cutting conditions to change the tool path and data, in order to achieve the most suitable state. Such as empty cutting, automatic lifting height change, cornering deceleration, heavy cutting deceleration, arc transformation. In particular, the length of the tool can be measured before machining to detect the shortest tool holding length, processing safety and stability to achieve the best condition. In addition to a complete protection of the lock code device, the protection of the software will not be stolen, followed by the built-in high-speed machining tools used in the tool library and processing methods, the cumulative preservation of the company knives and processing KNOW-HOW, reduce the impact of staff turnover on the company . In terms of safety performance, the CNC program needs to be fully verified by the entity to produce the optimization program and completely solve the problems of overcutting, knife striking and interference. At the same time through the entity comparison more comprehensive inspection of unprocessed areas. Can have 3D three-dimensional function of advance and retreat knife, cutting in line with the best mold quality and extend the maximum tool life, machining fewer joints mark less. At the same time also requires the same amount, such as load, the direction of cutting, which not only protects the spindle life, saving more than half the cost of the tool, but also to enhance the efficiency of servo processing and shorten the processing time, according to existing customer feedback, the company imported high- After processing, the processing and grinding time compared with the original processing time reduced by 2/3. Finally, it is required to provide full physical simulation capabilities, such as knife optimization, knife handle, tool interference check, cornering corner processing, etc., which in addition to defensible cutting safety can also remove the empty cut. 5 environmental requirements (1) fully enclosed shroud, to prevent the processing of oil and gas flying air pollution. (2) processing oil and gas blowing device to reduce the processing of a large number of oil and gas production. Based on the above requirements, Dongtai Seiki introduced a series of new models of mold high-speed milling such as MDV-508HSC high-speed vertical processing machine, which not only can help customers reduce the manufacturing process and shorten the delivery time, but also achieve high-quality surface precision and reduce Polishing time, can be directly milled HRC58 and above high hardness materials, and the knife diameter clearance angle (Min. Up to R0.1) processing is almost mirror finish, can reduce the number of discharge processing and subsequent manual polishing time, not only greatly enhance the production capacity Also improve the quality of the mold to meet the needs of customers.
Dimming glass can make an open space immediately disappear invisible, but also allows hidden scenes to emerge instantly, and this change can be achieved simply by pressing a switch.
This new building material, which sounds amazing, has actually been around for more than 20 years, but it is not known to the general public because it is expensive. At present, light-adjusting glass is mainly used in the field of tooling.
For example, the auditorium of the National Theater and the observation window of the rehearsal hall, Chang'an Club, and the mobile business hall all use this kind of dimming glass.
The smart glass has efficient openness and privacy, can be used in prison visit rooms, tion rooms, isolation rooms etc.
The bulletproof dimming glass partition for bank counter, can easily switch from transparent state for service time and the atomization state for oof time.
