Surface grinding machine is not it is widely believed that is the kind of plane only grinding machine. To understand the world today the trend of the development of surface grinding machine, people's this view will be changed. Today's flat grinding is the development trend of steering forming, steps, cut, rapid jitter, the three dimensional space curve surface grinding processing. In other words, flat grinding is grinding machine kind of machine tool in the development of the potential maximum of machine tools. Our country flat grinding factory should jump out of the traditional plane grinding thinking, turn to curve or profile and the plane grinding processing thought further development, in order to form our own characteristics of technology and products.

The development trend of surface grinding machine

According to incomplete statistics, this exhibition has more than 20 flat grinding professional factories to flat grinding physical form exhibition, including Europe, America, Japan and China's main flat grinding factory, with more than 60 sets flat grinding, the main features are:

Look - from the specifications, with small flat grinding is given priority to, in all flat grinding exhibits, mesa width of 200 mm the following almost 50%, the small size of the machine tool, transport and layout more convenient; Foreign flat grinding regardless of ordinary, precision and high precision accuracy grade, relatively small specification machine, precision easy to do very high; In the international market, medium and small size flat grinding of potential demand.

- from the control point of view, more than 70% of the flat grinding exhibits for numerical control type, have single shaft, biaxial and three axis nc, the most up to five axis control, especially in more than 400 large size model, all for numerical control type. Due to the development of the technology level to function change, flat grinding has from the traditional plane grinding to forming grinding transformation, conventional control has been difficult to achieve the requirements of function. Nc flat grinding has formed a market trend.

-- look from the function, more than 50% of the flat grinding is to be used not only for horizontal plane processing, and steering forming, steps, cut, rapid jitter, the three dimensional space curve and surface grinding processing, such as ELB, BLM company based in flat grinding changes into five axis gang grinding center, can realize the planar complex surface grinding; Unison, Trutech company's flexible grinding system, can realize forming, centerless, cylindrical, tools, outline and grinding process; There are abundant blessing, Parker company fast jitter mill etc, reflecting the flat grinding is grinding machine kind of machine tool in one of the biggest potential evolution models.

Development present four big change

As an international manufacturing technology exhibition, metal-cutting machine always all is the biggest exhibition point, IMTS also no exception. Processing center, turning center, grinding center, CNC lathe, CNC milling, CNC boring and metal-cutting machine tools, constitute the huge exhibits group, these from the traditional cutting principle combined with modern design concept and advanced control technology and integration into gold cutting machine tool, represents the developing direction and trend of the machine tool. - high speed, composite, high precision, high rigidity is still metal-cutting machine tools development advocate tone, but also have new changes. Composite, already from the original for composite and composite to consider from the practical efficiency is given priority to, such as car, milling composite, vehicles, milling, drilling of composite, milling machine and the electric spark compound; Look from the function, the hybrid machine tool's pertinence is very strong, in view of some parts consideration; From the precision, the positioning accuracy < 2 μ m, repeat positioning accuracy acuities ± 1 μ m of machine tools has everywhere; From the spindle speed to see, 8.2 kW spindle 60000 r/min, 13 kW 42000 r/min, high speed is not small power spindle proprietary characteristic; Look from the rigid, has appeared for processing 60 HRC hardness material processing center.

- modular design in machine tool manufacturing has been applied to the pink of perfection. Transverse series, longitudinal series, the full range, span series of modular design, the exhibits reflect incisively and vividly, no matter be large Wei, makino and as a representative of the Japanese machine, or Haas, Cincinnati, etc as a representative of the machine tool, the same two platform exhibits, externally look, as if just the same, but function is completely different, consisting of many module is universal.
