With this era is now more and more high-tech, there are very new products have emerged, precision machining has also been reused by many people, so do you know its benchmark this problem, go together to understand it.
1. Beijing precision machining design benchmark
In the parts diagram to determine the location of other points, lines, surface benchmarks, called the design benchmark. Precision machining of the sleeve parts, the outer circle and bore design benchmark is the axis of the part, the end face A is the end face B, C design benchmark, the axis of the bore is the radial runout of the outer circle benchmark.
2. Process
Beijing precision machining parts in the processing and assembly process used in the benchmark, known as the process benchmark. Process benchmark according to the different uses are divided into assembly benchmark, measurement benchmark and positioning benchmark.
(1) assembly benchmark assembly to determine the position of the part in the component or product benchmark, known as the assembly benchmark.
(2) measurement benchmark used to check the size and position of the machined surface benchmark, known as the measurement benchmark. The bore axis is to check the radial runout of the outer circle of the measurement benchmark; surface A is to check the length L size l and the measurement benchmark.
1 machine tool composite technology to further expand with the progress of CNC machine tool technology, composite processing technology is becoming increasingly mature, including milling - turning composite, milling composite, turning - boring - drilling - gear processing and other composite, grinding composite, forming composite processing, special composite processing, etc., precision machining efficiency greatly improved.
2, Beijing CNC machine tools have new breakthroughs in intelligent technology, the performance of the CNC system has been more reflected. Such as: automatic adjustment of interference anti-collision function, after the power failure, the workpiece automatically exit the safety zone power failure protection function, processing parts detection and automatic compensation learning function, intelligent enhance the function and quality of the machine tool. More five-axis linkage high-speed machining center was introduced.
3. The robot makes the flexible combination of higher efficiency robot and host of flexible combination is widely used, making the flexible line more flexible, further expand the function, flexible line to further shorten, higher efficiency. Robots and machining centers, milling machine tools, grinding machines, gear processing machine tools, tool grinding machines, electrical processing machine tools, saws, stamping machine tools, laser processing machine tools, water cutting machine tools and other forms of flexible units and flexible production lines have begun to apply.
