Description

Technical Field

[0002] The chip removal and filtering device of the machine tool is used to collect various metal and non-metal waste chips generated during the machining process of the machine tool, transfer the waste chips to the equipment for collecting the waste chips, and recycle the coolant. Existing CNC machine tools are equipped with chip removal and filtering devices. Among them, each chip removal machine is equipped with a chip car at the chip drop port, which makes the cost high and occupies a large area. At the same time, each chip removal machine needs to be cleaned manually regularly, resulting in a waste of human resources; in addition, the waste contains chip fluid. The more chip drop ports of the chip removal machine, the more chip fluid is wasted, which cannot be reused and will cause environmental pollution; furthermore, the chip removal and filtering device equipped with a single machine tool has great limitations, which is limited by the size of the machine tool and the planning of the floor space.

[0003] With the accelerated pace of modern production and the improvement of machine tool processing efficiency, more and more companies are adopting a complete set of centralized chip removal and filtration systems in the workshop to improve the processing efficiency of CNC machine tools and realize the design concept of digital factory. Centralized chip removal is generally required to be under the pit to maintain the aesthetics of the workshop. Centralized filtration is generally overhead, that is, upper discharge and upper supply or lower discharge and upper supply. However, different filtration methods depend on the factory conditions and the nature of the chips. For old factories with limited conditions, the cost of centralized chip removal and filtration is too high. Considering the cost, many companies still choose to equip each machine tool with a single chip removal filter. Utility Model Content
