External machine tool protection, as opposed to internal machine tool protection, is used to protect the exterior of the machine tool. When workers pass by the machine tool, the high-speed operation inevitably brings in a lot of dust and debris. With the protection of the cover, the machine tool will be kept very clean, thus increasing its service life. Internal machine tool protection is used to protect all vulnerable parts inside the machine tool, preventing injury to operators during operation. We provide users with high-quality, aesthetically pleasing, sophisticated, high-precision, and high-performance modern professional products, mainly used for engraving machine protection, precision engraving machine protection, pipe bending machine protection, slitting machine protection, automated equipment protection, CNC machine tools, etc.
Machine tool external guards protect the internal rigid guideways, linear guideways, ball screws, or transmission racks from external corrosion and damage. There are many types: accordion guards and steel plate guards. These two are used on guideways. There are also ball screw guards, which come in round, square, and polygonal shapes. These types differ in their construction, including wire-supported types, stitched types, roll-up guards, and armor-like guards, among others.
The conventional structure of machine tool external protection is as follows:
1. The structure of the left and right protective covers for machine tool exterior protection: Whether it is a fully enclosed or semi-enclosed CNC machine tool, the left and right protective covers are divided according to their spatial location. For ease of installation and maintenance of the protective covers, movable doors are generally provided on the sides of the left and right protective covers. The size of the movable doors should be appropriate, and the movable doors are connected to the cover body using strong hinges and are equipped with door locks.
2. Protective door structure for machine tool external protection: CNC machine tool protective doors can be divided into two types in terms of appearance: straight and curved. The shape of the door should be matched with the overall shape of the CNC machine tool.
3. The rear cover structure improves the humanization of the machine tool's external protective structure design from an ergonomic perspective.
Machine tool protective device manufacturers advise you to pay attention to a series of appearance issues before purchasing and using them:
1. The machine tool's exterior surface should be free from protrusions, dents, roughness, and other damage not specified in the drawings;
2. The protective cover of the machine tool should be flat and symmetrical, and should not be warped or dented;
3. The edges of the exposed mating surfaces of machine tool parts should be neat and uniform, without obvious misalignment. The misalignment should not exceed 2mm, and the unevenness should not exceed 1mm.
4. The mating surfaces of the machine tool's doors and covers should fit snugly against the machine tool, with a gap not exceeding 1.5 mm and a gap unevenness not exceeding 1 mm.
5. Exposed welds should be trimmed to be straight and uniform;
6. The screw inserted into the countersunk hole should not protrude above the surface of the part, and there should be no obvious eccentricity between its head and the countersunk hole. The locating pin should generally protrude slightly above the surface of the part, and the end of the bolt should protrude 1 to 3 threads above the end face of the nut.
7. Exposed parts of the machine tool should be free from bumps and rust, and the ends of screws, rivets, and pins should be free from defects such as twisting and hammering.
8. The color tone of plated and blackened parts should be consistent, and the protective layer should not fade or peel off;
9. Exposed parts of electrical, hydraulic, lubrication and cooling pipes should be arranged compactly and neatly, and fixed with pipe clamps. Pipes should not be twisted or folded.
10. All unmachined surfaces of machine tool parts should be painted yellow.
11. All signs should be clear, correctly positioned, flat and secure, not crooked, and complete.
