Drilling, milling and tapping center machine is a kind of machining equipment which has different specifications of through-hole or blind hole in the shell, equipment end face, nut and other tools of CNC machine tool, and the thread, screw or thread are machined on the inner side of parts. Let’s first understand the characteristics of drilling and milling center machine.
The drilling, milling and tapping center machine is very simple when adjusting the model. The automatic reverse device can freely adjust the working stroke of the drilling and milling tapping center machine. The processing workpieces with shallow holes and holes can be easily adjusted. In the double installation device, the screw tap can be prevented from damage, and the spindle can be back and forth and up and down. The double safety clutch is specially designed for the advance and retreat of the cutter. The spindle can stop automatically and the tool will not be damaged by the reversing tool withdrawal. The gear of drilling and milling center machine matches with the pitch between the spindle and the spindle to promote complete matching, vertical stability, accuracy, and high precision. When the screw taps, it can move forward and backward without output. At the same time, it can be configured with multi axis synchronous processing, and the production efficiency will be greatly improved
It can also reduce and save labor: drilling, milling and tapping center machine combines tapping and stamping of parts into a process, which can be fully automated, thus saving labor costs. It can also reduce adverse effects. Accurate positioning of drilling and milling center machine can reduce the damage probability of taps. At the same time, it can also reduce the accurate positioning of drilling and milling center machine, and provide the probability of waste products caused by errors. So what are the common problems in the use of drilling milling tapping center machine? How to solve this problem? Well, today’s editor will help you solve these problems.
- Breaking of drill tap
Solutions: when the tap of drilling and milling center machine is broken, the diameter of thread bottom hole should be correctly selected; the drilling depth of grinding edge angle or spiral groove tap should reach the specified standard; the cutting speed should be appropriately reduced and selected according to the standard; when tapping, correct the tap and bottom hole to ensure its coaxiality meet the requirements, and select floating tapping chuck; increase the tap The front angle, shorten the length of the cutting cone; ensure that the hardness of the workpiece meets the requirements, select the safety collet; the anti County tap wear should be replaced in time.
- Tap tooth breakage
Solution: tap tooth chipping, properly reduce the tap front angle; appropriately increase the length of the cutting tap; reduce the hardness and replace the tap in time. If the tap is worn too fast, the cutting speed should be reduced properly; the front angle of the tap should be reduced to lengthen the length of the cutting cone; the cutting fluid with good lubricity should be selected; the workpiece to be machined should be properly heat treated; and the tap should be properly sharpened.
- Excessive pitch diameter of thread
Solutions: if the pitch diameter of the thread is too large, select the tap pitch diameter with reasonable accuracy level; select the appropriate cutting fluid and reduce the cutting speed appropriately; correct the coaxiality of the tap and the bottom hole of the thread when drilling and milling the tapping center machine, and use the floating chuck; appropriately reduce the front angle and the back angle of the cutting tap; remove the burr generated by the grinding tap and appropriately increase the length of the cutting tap.
- Too small pitch diameter of thread
In addition, it is necessary to increase the cutting accuracy of the tap and to select the proper cutting angle of the tap.
- The surface roughness of thread is too large
Solution: if the surface roughness value of thread is too large, properly increase the front angle of the tap to reduce the cutting angle; conduct heat treatment to properly improve the hardness of the workpiece to ensure that there is a low surface roughness value on the front cutter surface of the tap; select the cutting fluid with good lubrication; appropriately reduce the cutting speed; replace the worn tap for the drilling and milling center machine.
Drilling, milling and tapping center machine is a kind of metal cutting equipment, of course, it can also drill holes, but from this name, we can see that it is also very aggressive. Well, after a simple understanding of the drilling and milling center machine, the next step is to analyze the current situation of the overall market.
The function of drilling, milling and tapping center machine is to drill the hole and tap together. From here, we can see that one of its characteristics is high efficiency, because it combines the two processes and completes it at one time.
In the absence of drilling and milling tapping center machine, we need to work together with drilling machine, lathe or manual wire drilling tools to complete what it has done now
