The grinder is a machine tool that uses abrasive tools to grind the surface of the workpiece. Most of the grinders use high-speed rotating grinding wheels for grinding processing, while a few use other abrasive tools such as oilstone, abrasive belts and free abrasives for processing. With the increase in the number of high-precision and high-hardness mechanical parts, as well as the development of precision casting and precision forging processes, the performance, variety and output of grinders are constantly improving and growing, so HOSTON grinding machine can provide you with grinding solutions in various fields.

With the rapid development of integrated circuits and computer technology, new vitality has been injected into the upgrading of numerical control hardware technology. Modern digital control systems commonly use VLSI, ASIC, and digital signal processing (DSP) technologies. Surface mounting (SMT) and three-dimensional high-density (3D) high density technologies are widely used in electrical installations to greatly improve system reliability.
High-speed, high-performance storage technologies such as flash memory and PCMCIA cards are extremely user-friendly. Thin film transistor liquid crystal display (TFTLCD) technology tends to flatten the display device, which facilitates the installation of electromechanical integration and improves the man-machine interface. As the core of the numerical control system, the processor uses a high-speed RISC CPU above the bit to ensure high-speed, high-precision CNC machining.
Architecture to open development
The discussion of open CNC has been for several years, but it should be noted that there has been no consistent definition of open architecture. Some users believe that Open Expression can accept locally used communication protocols; while others believe that openness means that all controllers have an identical user interface; for machine tool application engineers, open means that the tool holder moves, sensors and Logical controls have standard input/output interfaces; for large companies and university research engineers, open style means that these are all blocks of blocks that are immediately available. Due to pressure from end-users and integrators (machine tool plants), the development of open architecture is moving forward and will continue. The current positive result is PC-based CNC, PC-based.
Real-time operating system enters CNC
Strictly speaking, CNC control software contains the idea of ​​real-time operating systems, such as task scheduling, memory management, interrupt handling, etc., but this technology is implicit, and CNC applications such as interpolation, servo, decoding Such as mixed. Every CNC system is unique and opaque. This situation is inconvenient for end users and system integrators. With the increasing popularity of open CNC, it is logical to study the application of real-time operating systems in CNC software. In particular, the recent rapid development of embedded real-time operating system technology, which will have a revolutionary impact on the development of CNC control software. Choose a suitable commercial embedded real-time operating system, and put the NC application software, such as interpolation, servo, decoding, and data processing, up “hangingâ€, and finally migrate to a hardware environment to form a numerical control system that will ultimately satisfy the users. This is the personalized CNC system, which will be the main direction of open CNC.
