As we all know, in the modern machinery manufacturing industry, enterprises have a wide range of demand for special machine tools. Generally, ordinary drilling machines have high labor intensity, low special performance, low productivity and no guarantee of accuracy; while special multi-hole drilling machines are convenient, labor-saving, easy to master, and are not prone to operating errors and failures. They can not only reduce worker fatigue, and ensure the safety of workers and drilling machines. It is safe and can also improve the productivity of the drilling machine. With the continuous development of science and technology, special drilling machines are widely used in manufacturing. In other words, the stronger the specialization, the better the company can guarantee the quality of its products. Therefore, the use of special machine tools plays a very important role in the competitiveness of enterprises.
The multi-hole drilling machine produced by our factory is especially aimed at the valve industry. It can realize all kinds of gate valves, butterfly valves, control valves and other valves. The three- or two-sided flanges made of cast steel or cast iron can be drilled and tapped at the same time. In addition to the amazing increase in valve efficiency, other main application areas, such as the processing of pump bodies, auto parts, engineering machinery and other parts, can also be used for the simultaneous drilling of end holes, middle holes, tapered holes and spherical holes on the workpiece. Hole processing. The multi-hole drill has two modes of hydraulic and numerical control system operation, which can realize automation, high precision, multi-variety, and mass production.
There are also some precautions when using multi-hole drills. We have made the following summary for this:
1) The drill bit must be individually customized and packaged, and it must be firmly fixed during transportation to avoid vibration and collision.
2) To measure the diameter of the drill bit, use a non-contact measuring instrument such as a tool microscope to avoid being injured by mechanical contact.
3) The multi-spindle drilling power head must use the drilling template positioning ring during use, so that the elongation of the drill bit installed on the spindle must be adjusted to be consistent. Multi-spindle drilling machines must pay more attention to this point, so that the drilling depth of each spindle must be Unanimous.
4) Check the wear of the cutting edge of the drill.
5) The multi-hole drilling machine should check the concentricity of the spindle and the chuck regularly. Poor concentricity will cause small-diameter drills to break and increase the hole diameter. Poor clamping force will cause the actual speed to be inconsistent with the set speed. There will be slippage between the drill bits.
6) The clamping length of the multi-hole drill bit on the chuck is 4 to 5 times the diameter of the drill shank to be clamped firmly.
7) Always check the spindle. The main shaft cannot be shaken to prevent broken drills and partial holes during drilling.
8) The positioning system on the workbench of the multi-hole drill is firmly positioned and laid flat, which prolongs the life of the drill bit and reduces the production cost and expense. Excessive grinding effect is counterproductive.
