Development and application of servo electric tapping machine
In today's era, the lack of skilled workers and the rising cost of wages, and the fierce competition in the market and the rapid changes in products, make the CNC electric tapping machine more able to show its characteristics, especially in terms of improving productivity, the servo electric tapping machine has Its unique features.
1.1 The principle of the tapping machine:
The drilling of the drilling and tapping machine uses a twist drill to machine holes in the material. This cutting method is called drilling. Drilling is the most used machining process in the machining of large workpieces. For example, large equipment has 50-60 large holes of 30-130mm. Because these holes are used differently, they are often completed through various processes such as drilling, reaming, boring, and tapping. In order to ensure the positional accuracy of the hole, the drilling must have a preparation process - a pressure-punching process. The sample punch is used to press the sample punch at the position where the surface of the workpiece needs to be drilled, so as to guide the drill bit during drilling to avoid the deviation of the drill hole. Then move the drilling and tapping machine to drill, ream, boring and tapping one by one, so the drill tapping design must be light and easy to move.
The tapping of the drilling and tapping machine is tapping on the drilled bottom hole with the tap of the national standard machine. The distribution on the large equipment is very uneven, and it is on the plane, on the side, and also on the top. Therefore, the drilling and tapping machine is required to be rigid, high in strength and light in weight, and convenient to move. The largest threaded hole on a large machine has the M130. The driller must have the function of machining large threaded holes. The machine tap refers to the high-speed steel grinding tap, which is suitable for tapping on the machine tool. The drilling and tapping machine must have the ability to use the tap of the national standard machine to reduce the use cost.
In addition to the drilling and tapping capability, the drilling and tapping machine should also have the ability of reaming and boring to meet the customer's requirements for various hole processing technologies.
