The development trend of today's surface grinders is to turn forming, stepping, cutting, fast shaking, and three-dimensional curved surface grinding. It can be said that the flat grinding is a type of machine that has a great potential for development in a grinding machine. China's flat mills should jump out of the traditional plane grinding thinking and turn to the idea of non-planar grinding such as curves or contours to further develop our own unique technologies and products.

First, the development trend of surface grinder

1. From the perspective of specifications, it is mainly based on small flat grinding. The table width is less than 200mm, which accounts for almost 50%. The transportation and installation of small-sized machine tools are convenient; the foreign flat grinding does not distinguish between ordinary, precise and high-precision precision grades. Compared with small-sized machine tools, the accuracy is easy to do very high; In the market, the potential demand for medium and small size flat grinding is very large.

2, from the control point of view, more than 70% of the CNC type, there are single-axis, two-axis and three-axis CNC, Zui up to five-axis control, especially the large-size models above 400, all CNC. Due to the development of the technical level leading to functional changes, flat grinding has changed from the traditional surface grinding to the forming grinding, and conventional control has been difficult to achieve functional requirements. CNC flat grinding has formed a market trend.

3. From the functional point of view, more than 50% of the flat grinding is not only used for horizontal plane machining, but also for surface grinding, such as forming, stepping, cutting, fast shaking, and three-dimensional space curves.

Second, the development of surface grinding machines presents four major changes

1, high speed, composite, high precision, high rigidity is still the main theme of the development of gold cutting machine tools, but there are new changes. Compounding has been changed from composite to composite and practical and efficient, such as car, milling compound, compounding of car, milling and drilling, milling machine and electric spark; from the functional point of view, the complex machine tool Very strong, for a certain type of parts; from the accuracy point of view, positioning accuracy <2μm, repeat positioning accuracy ≤ ± 1μm machine tools have been everywhere; from the spindle speed, 8.2kW spindle up to 60,000r / min, 13kW up to 42000r /min, high speed is not a proprietary feature of small power spindles; from a rigid standpoint, machining centers that can process 60HRC hardness materials have emerged.

2, modular design has been applied in the manufacture of machine tools. The horizontal design, vertical series, full series, and cross-series modular design, whether it is a Japanese machine tool represented by Otsuka and Makino, or an American machine tool represented by Haas, Cincinnati, etc., looks exactly the same, but the function is completely Different, many of the modules made up of surface grinders are universal.

3. The concept of fully automatic has changed. The traditional fully automatic machine tool uses a pneumatic or hydraulic manipulator to realize the automatic loading and unloading of the workpiece. Now, the real multi-joint serial robot is used to realize the loading and unloading of the workpiece, including the stacking of completed parts. . The scope of control is increased, the flexibility of the assembly line is strengthened, and the auxiliary supporting machinery is greatly reduced.

4. Environmental protection requirements are getting higher and higher. Most of the exhibits on display exhibited a fully enclosed enclosure with absolutely no chipping or splashing of cutting fluid. On the other hand, the exhibition of a large number of industrial washing machines and cutting fluid processor systems also reflects the increasing demands of modern manufacturing for environmental protection.

Third, the fundamental lies in design innovation

1. Surface grinder is the most promising machine tool in grinding machine tools.

In addition to the traditional surface grinding function, it can be transformed into a grinding machine such as an outer circle, a curve, a tool, and a centerless machine based on a large-sized bed, a carriage, a table top, a grinding head, and the like. China should complete the development of the flat grinding specification series, and jump out of the traditional plane grinding thinking to the non-planar grinding process such as curve or contour to further develop and form the technology and products with our own characteristics.

2, modular design will be a main line throughout the whole process of product design, whether it is the trend of machine tool technology development or market competition; whether it is the need to reduce costs, or the need to improve product quality, we require our products in the future In the development and design, we must do a good job in modular design.

3. The development of the world's surface grinder industry is fundamentally the development of design innovation concepts. The traditional metal cutting principle, with a new modern design concept combined with advanced control technology, is driving major changes in machine tool technology.
