1. High speed, compound, high precision and high rigidity of surface grinder are still the stagnation and falling tone of metal cutting tools, but there are new changes. Compounding has changed from compounding for compounding to practical and efficient thinking, such as turning and milling compounding, turning, milling and drilling compounding, milling machine and welding flower compounding; From the point of view of performance, the alignment of compound cutting tools is very strong, which can be considered for a certain type of complete machine; In terms of accuracy, the positioning accuracy is less than 2 Μ m. Repeated positioning accuracy ≤± 1 Μ M's cutting tools are everywhere; In terms of the speed of the main optical axis, the 8.2kw main optical axis reaches 60000r / min and the 13kw main optical axis reaches 42000r / min. high speed is not the only feature of the low-power main optical axis; From the point of view of rigidity, the machining core that can process 60HRC hardness data has emerged.

2. The concept of fully active surface grinder has changed. The traditional fully active cutting tool uses a pneumatic or hydraulic manipulator to realize the active loading and unloading of workpieces. At the beginning, the real multi joint series tool was adopted to realize the loading and unloading of workpieces, including the stacking of the whole machine. The scale of mastering is increased, the sensitivity of line assembly is enhanced, and the machinery of simultaneous auxiliary matching is greatly reduced.

3. The environmental protection of surface grinder should be higher and higher. Among the exhibits on display, most of the cutting tools are produced with fully open covers, which is relatively free of chips or cutting fluid splashing. On the other hand, a large number of light industrial cleaners and cutting fluid solvers were displayed in pieces, which also reflected the increasing demand of the ancient manufacturing industry for environmental protection.
