What preparations should be made for the machining accuracy of rocker drill?

Radial drilling machine is a kind of precision manufacturing equipment, so the accuracy of radial drilling machine is directly related to the vital interests of downstream customers of machine tools. If there is a problem with the radial drilling machine in parts manufacturing enterprises, a large number of products will be unusable, which will directly affect the economic benefits of customers. Therefore, the reputation of radial drilling machine enterprises is based on the accuracy of products.

In order to ensure the machining accuracy of radial drilling machine, the following points need to be done:

1, when machining a rocker drill, it is best to match the spindle taper hole with the drill bit taper handle, and it is best to use a special grinding taper hole. 2. The main shaft sleeve of the radial drilling machine and the guide shaft sleeve of the box are backed up to ensure that the error is within the controllable range.

3. In order to ensure the reset accuracy and firm installation of the radial drilling machine, it is necessary to readjust the processed workpiece.

4. In the process of inspection, if it is found that the workpiece is not suitable for use. Reasonable selection of clamping parts and correct clamping.

5. If the spindle is worn, the drill bit will not be vertical. Scrape with scraper, and scrape neatly. The difference should be less than 0.02 mm. ..

6. If the length of the main cutting edge of the drill is different. The cutter head and cutter should be repositioned.

When processing and manufacturing various workpieces, the accuracy requirements of radial drilling machine should be met. Including drilling, reaming and other processes. It is also required to meet the requirements of some product types completed by drilling rigs to meet the diversified needs of some customers. Install the radial drilling machine according to the standard, drill holes with high-speed drill, and specify the maximum and minimum drilling diameter. In order to improve production efficiency, simplify the use of workers and ensure the accuracy and stability of workpieces, the use of radial drilling machine must meet the production needs of large-scale parts processing enterprises. Because the radial drilling machine is widely used, it must be lubricated in strict accordance with the lubrication standards of machine tools, and the lubricating oil should be clean, acid-free, water-free and free of hard particles. When it is not used for a long time, it needs rust and rain protection.
