  Machine tool fixtures  must meet the following basic requirements: 1. The machining accuracy of the workpiece must be guaranteed. The key to ensuring the machining accuracy lies in the correct selection of positioning datum, positioning method and positioning components. If necessary, positioning error analysis is also required, and attention needs to be paid to the structure of other parts in the fixture for processing The impact of accuracy, to ensure that the fixture can meet the requirements of the machining accuracy of the workpiece. 2. The complexity of the special fixture for improving production efficiency should be adapted to the production capacity, and various quick clamping mechanisms should be used as much as possible to ensure convenient operation, shorten auxiliary time, and improve production efficiency. 3. Good process performance, simple and reasonable structure requirements for special fixtures, easy to manufacture, assemble, adjust, inspect, maintain, etc. 4. The

With the changes in the industrial age, traditional processing methods can no longer meet the precision requirements and efficiency of production. Since the emergence of EROWA, it has shocked the manufacturing industry that there is such an efficient processing method. Compared with the traditional   processing  method, the efficiency of erowa fixture has increased by about 40%. So what are the advantages of the repeated positioning fixture system? Let POFI  fixture manufacturing company   answer for you: 1. Precision: The static tolerance repeatability of the EROWA fixture is ±0.002mm. 2. Clamping correction speed: When EDM, CNC, EDW are in the process of processing, only need to find the center once, in the back of the workpiece does not need to hit the table, touch the number and the center rod. And the workpiece can be clamped outside the machine, reducing the downtime to ten seconds, greatly improving the efficiency of the machine. 3. Reduce human error: The EROWA fixture system a
