The machining of large holes over 100 mm usually requires the use of special tools and techniques. The following are some possible machining methods:
1. Boring: Use a boring tool, such as a boring tool or boring machine, to expand the initial aperture to the desired size. This method is suitable for machining with larger apertures, but requires higher accuracy and stability.
2. Drilling: Use a large drill press or drill to gradually expand the aperture. This method is suitable for larger apertures, but may need to be drilled several times to reach the desired size. 3. Milling: Using a large milling machine or milling cutter, the initial aperture is changed to the desired size by rotating the cutter. This method is suitable for machining with larger apertures, but requires higher accuracy and stability.
4. Laser cutting: Using laser cutting technology, the material is directly cut through the laser beam to form a large hole of the required size. This method is suitable for a variety of materials and apertures, but requires specialized equipment and technology.
Each of these methods requires the selection of appropriate tools and techniques according to the specific processing requirements and materials. For large hole machining exceeding 100 mm, it may be necessary to use a combination of methods to achieve the best results.
Large holes of more than 100 mm can usually be machined by the following processing methods:
1. Drilling: Drilling with a drill bit or boring tool. For larger apertures, a large-diameter drill bit, a drilling machine, or a drill unit on a vertical milling machine can be used. 2. Milling: The milling cutter is used to rotate the workpiece, and the desired aperture size is achieved by controlling the feed and speed of the milling cutter.
3. Boring: Use the boring tool to rotate the cutting on the workpiece, and achieve the desired aperture size by controlling the feed and speed of the boring tool.
4. Hole making: Using a hole making machine for hole processing. The hole making machine usually has a high cutting speed and feed speed, which can quickly and accurately complete the processing of large holes.
According to the specific workpiece material and requirements, you can choose different processing methods. When operating these processing machines, be sure to operate them safely and follow the relevant operating guidelines and safety specifications. If necessary, you can consult professional processing personnel or engineers for guidance.
The correct processing technology is the use of magnetic drilling, drilling, reaming. If there is no magnetic drilling, the use of vertical lathe, drilling, reaming, boring, more economical and cheap.
First drill to 5O mm, then lathe to 100 mm, or boring to 100 mm.
