1. High-speed, precision, multi-axis, complex, intelligent, automation is the direction of machine tool technology
At this show, Mori Seiki, Mazak, DMG, Siemens, Haas, Doosan machine tools to bring such international giants have unveiled the latest products and technology, Dalian Machine Tool Group, Qinchuan Machine Tool Group, Qi a machine , Qi 2 plane in Beijing, a tool, method for numerical control, the number of broad land, and many domestic companies are also testing this exhibition to show its next-generation products.
This exhibition shows the current machine tool industry, technology trends, including:
1.1 high-speed precision machining Machines to high-speed direction, not only can greatly improve the processing efficiency, lower processing costs, but also improve the part surface quality and precision machining. Ultra-high-speed machining technology to the manufacturing sector for efficient, high quality, low cost production of a wide range of applicability.
20 since the 90's, European, American, Japanese and competing development and application of a new generation of high-speed CNC machine tools Accelerate the pace of development of high-speed machine tools. High speed spindle unit (spindle, speed 15000-100000r/min), high speed and high plus / minus feed speed moving parts (fast motion speed 60 ~ 120m/min, cutting feed rate up to 60m/min), high-performance CNC and servo systems, and CNC tool systems have a new breakthrough. In recent years, ultra-high speed cutting mechanism, hard wear-resistant tool material and longer life Abrasive Abrasive, high-power high-speed spindle, high plus / minus speed linear motor drive feed components and high performance control system (including monitor systems) and protection devices in a series of technologies to solve key technology for the development and application of a new generation of high-speed CNC provides a technical basis.
In high-speed machining, turning and milling in the cutting speed, the current has reached more than 5000 ~ 8000m/min; spindle rotation in 30000r/min (some up to 100 000 r / min) above; table of the mobile speed ( feed rate): In the resolution of 1 micron, the in 100m/min (some to 200m/min) above, at a resolution of 0.1 microns, more than in 24m/min; automatic tool changing speed within 1 second; small segment interpolation feed rate to 12m/min.
This show, Mori Seiki, DMG, law firms because of CNC related technology products on display, such as DMG's high-speed cutting precision machining center HSC20Linear, the maximum acceleration up to 2g, X / Y / Z axis fast transfer speed of 30m/min, and with very high precision. The 5-axis gantry machining center designed by increased flexibility and allows for 5-axis simultaneous machining. Through the X / Y / Z axis with a precision linear motor cooling device to achieve a high dynamic, in the A / C axis with a straight line with a water-cooled torque motor drives, in the position of each axis has a direct measurement system. In addition, forced cooling device with high power spindle with HSK-32E Chuck , Speed up to 42,000 rpm, for HSC milling cutter 24 is also equipped with automatic tool changing manipulator.
1.2 multi-axis After 50 years of development, multi-axis CNC System CNC machine tools to become the world's most cutting-edge technology development areas. Linkage of high-performance multi-axis CNC machine tools, can simultaneously control more than four axes of the linkage. Usually three-axis machine tool can achieve two axes, two axes and a half, three-axis machining; five-axis machine tool can achieve five-axis, you can only use three-axis simultaneous machining, while the other two axes are not linked. Multi-axis CNC machine tool can Milling , CNC boring machines, CNC drilling machines and other functions together, in a clamping part, they can be machined surface for milling, boring, drilling, expansion, joint and multi-tapping and other machining processes, can effectively avoid causing many to install positioning error, can process complex shapes, high precision parts, such as the impeller blade.
This exhibition, the large number of foreign exhibitors showcased the multi-axis NC products. Domestic enterprises, the central bus-type high-grade new generation of CNC CNC HNC-32 are more remarkable, the system is based on industrial PC, a multi-processor and bus architecture for the hardware platform, real-time operating system, open software platform for the use of hardware high processing speed and software, the advantages of open and flexible to achieve multi-axis, multi-channel high-speed, high precision motion control. Maximum support 4-channel, 32 feed axis, 4 axis, each channel supports maximum 9 axis. At present, the central NC mid-range, high-grade digital systems and equipment manufacturers to achieve a bulk package, has more than 60 more than 5-axis NC system in the aviation, marine, electric power, automobile and other key business success in many areas of application. This exhibition, some machine tool manufacturers display the configuration of Huazhong CNC machine tools, machine tools on display, including five-axis machine tools, machining centers, CNC milling machine and so on.
1.3 composite Order to achieve the complex shape workpieces, so that complex processes and complex types of processing completed in one machine, this machine is called machine tool. In other words, the composite machine can be completely different nature of the process of processing. Composite milling machine with composite, composite and other types of milling through a variety of composite, can improve processing efficiency. Such as Mori Seiki MT-250S composite machine, Lathe Functional integration with machining centers, process highly concentrated, in essence, functions with 6 spindle axis compound lathe.
Domestic enterprises, the display of the VTM180 Qinchuan machine milling machining center complex, this machine is I am China Manufacturers writer, reports some information about alex evening dresses , mini sarong.
