There are not many surface grinder manufacturers participating in CIMT 2015, and most of them are compound grinding centers, CNC surface grinders and CNC grinding machines. Let's take a brief introduction and commentary on the exhibits as an example. 
When the machine is running the program, the user can also import and export the program through the USB interface; the program can be interrupted at any node, and the machine can automatically return to the interruption point to continue running after the interruption. For example, the detection of parts can be easily interrupted by the program, and can be operated by keyboard, mouse or handwheel.
The machine tool adopts the sliding saddle structure design, the distance between the grinding wheel and the vertical guide rail of the grinding head is constant, the saddle and the worktable directly bear the grinding force, ensuring the stability of the grinding precision; the newly developed X-axis dynamic sliding guide rail, The new, wear-resistant, friction-reducing EasySlide coating ensures excellent smoothness for extremely high precision and excellent surface quality.
The machine is flexible and can be equipped with various CNC indexing units, tool magazines and measuring systems according to the processing requirements, especially suitable for composite processing. The high spindle power allows for a wide range of profile grinding to powerful peristaltic grinding.
The machine body material is artificial marble, and the rigidity of the machine tool is significantly improved. The independent front and rear beds are connected and fixed by casting method, which ensures high-precision machining of all parts and precise adjustment of the precision of each part before casting. At the same time, the machine has excellent shock absorption performance and good thermal stability; Rolling guide, three-axis using ball screw and servo motor drive; the system uses Siemens 840D.
The machine is flexible and can be equipped with various CNC indexing units, tool magazines and measuring systems according to the processing requirements, especially suitable for composite processing. The high spindle power allows for a wide range of profile grinding to powerful peristaltic grinding.
All structural parts of the machine are made of sturdy castings. The weight of the bed is large, which guarantees excellent stability and rigidity. The linear roller guides are pre-tightened with high precision in both the vertical and horizontal directions, thus ensuring grinding rigidity and feed. Sensitivity; longitudinal and vertical movements are driven by AC servo motors. For the characteristics of machined parts, HEIDENHAIN high-precision linear scales are used for closed-loop control in the vertical direction to ensure precise positioning in the vertical direction; encoders are used in the lateral direction of motion. Position feedback semi-closed loop control.
The control system adopts Z-control special CNC system developed by ourselves, which is easy and comfortable to operate; automatic compensation of grinding wheel dressing; automatic grinding cycle and dressing cycle program; 10.4 inch LCD color touch screen; electronic handwheel for horizontal and vertical directions Right knife.
The machine tool table moves back and forth (Y-axis) guide rails and the grinding head moves up and down (Z-axis). The guide rails are high-precision pre-tightening linear guides. The left and right movements of the table (X-axis) guide rails are double V hard rails and fully enclosed shields. The machine tool adopts Taiwan's new generation CNC system, and on this basis, it carries out secondary development, perfect man-machine picture, and simple automatic CNC machining.
Built-in various grinding wheel dressing cycle procedures, such as: bottom, bevel, inner and outer fillet, complex angle, curved surface, etc.; built-in various grinding cycle programs, such as: plane, step, and other deep groove, etc. Deep groove, curved surface and other modes; with hand wheel simulation grinding path function, handwheel rotates machine tool running path, handwheel stops machine tool stops, convenient program test, avoid collision. The processing parameter screen can be stored directly for easy recall when next time.
The starting point of the surface grinder in this exhibition is relatively high, mostly based on precision, numerical control and composite processing, which fully demonstrates the next development direction of the surface grinder, namely precision, special composite, numerical control and easy operation to reduce labor costs. From the exhibits of this exhibition, there are not many standard surface grinders, most of which are improved on the basis of surface grinders, that is, for the processing of industrial parts and parts, the function of surface grinders is added to realize the processing of parts. Forming compound grinding machines and special grinding machines; overseas machine tools, especially Germany and Switzerland, have a high overall level of products, and have made great efforts in high precision and compounding. Therefore, domestic machine tool manufacturers still have a long way to go in terms of high precision, CNC composite machining, reliability and precision retention. We need to calm down and work hard on machine materials, manufacturing process equipment, machine tool performance, quality, reliability, etc., in order to reach advanced levels.
