What is the difference between a machining center and a drilling and tapping center

The difference between machining center and drilling center is from five aspects: main application, application, shape, tool magazine selection and rapid traverse speed.

First, the difference from the main application.

The application of machining center is relatively common, mainly for processing plane, curved surface and other shape equipment.

The drilling and tapping center is mainly used for drilling and tapping.

Second, the difference can be seen from the point of view.

Machining centers can be used for milling.

The drilling and tapping center can only carry out slight milling processing, because the spindle power of the drilling and tapping center is not very large, and it cannot carry out strong milling and large-load machining.

Third, the difference is seen in terms of appearance.

The machining center is a little more than the drilling and tapping center in terms of appearance.

The shape of the drilling and tapping center resembles the form of a large turntable.

Fourth, look at the difference from the choice of tool magazine.

The machining center is mainly a bucket hat tool magazine and a disc tool magazine.

The drilling and tapping center is mainly turret tool magazine, turret tool magazine.

Fifth, the difference is seen in terms of rapid traverse speed.

The rapid traverse speed of the machining center is not as fast as that of the drilling and tapping center.

The drilling and tapping center adopts linear guide rails, and the rapid traverse speed is faster than that of the machining center. The machining efficiency of the machine tool is obvious.

With the vigorous development of the domestic industrial manufacturing industry in modern society, various industries are using machining center equipment for abrasive processing, many customers still know more about the machining center, when someone says that the drill and attack center, many people are stupid and unclear. How much do you know the difference between a drilling and tapping machine and a machining center? Xin Tenghui CNC (drilling and tapping center manufacturer) tells you:

Differences (1) Appearance: the drilling and tapping center is a little smaller than the machining center in shape; The shape of the drilling and tapping center resembles the form of a large turntable. (2) Rapid traverse speed: The drilling and tapping center adopts linear guide rail, and the rapid traverse speed is faster than that of the machining center.

The machining efficiency of the machine tool is obvious. (3) Application: The application of machining centers is relatively common, mainly for processing planes, curved surfaces and other shape equipment. The drilling and tapping machine is mainly used for drilling and tapping; (4) Tool magazine selection:

The machining center is mainly a hat type tool magazine and a disc tool magazine, while the drilling and tapping center is mainly a turret tool magazine and a turret tool magazine.

The similarities between the machining center and the drilling and tapping center, literally, have the word "center", which shows that they are both a kind of metal cutting machine tool and CNC machining equipment. In terms of style and function, the machining center and the drilling and tapping are extremely similar. How much do you know the difference between a drilling and tapping machine and a machining center?

The differences between machining centers and drilling and tapping centers are as follows:

Drilling and tapping center is a kind of metal cutting machine tool, is a set of cutting, drilling, tapping as one of the machine tools on the market, fast work efficiency and high precision, is derived from the traditional metal cutting machine tool - vertical machining center (computer gong) The area and processing stroke are smaller than the traditional vertical machining center, mainly used for processing light and small metals.

So what is the difference between a drilling and tapping center and a machining center? Let's find out.

1.Its fuselage is equipped with a large pitch screw and roller linear guide, so the rapid displacement speed is several times faster than the traditional vertical hard way machining center, and the general speed reaches 48000mm min or 60000mm min. However, in terms of cutting feed strength, it is inferior to that of hard way machining center.

2.The machine tool is equipped with a clamping arm (servo) type or a synchronous-moving tool magazine, which can give better play to the speed of tool changer tool change.

3.The important thing is to play with the spindle, at present, most manufacturers have used the direct drive (direct connection) spindle, this type of spindle is characterized by high speed can be quickly reversed, the success of this type of machine tool can be quickly cut, drilling, tapping, which is also its name.

4.The specification of the commonly used drilling and tapping center spindle is BT30, and the speed is generally 15000rpm 20000rpm and 24000rpm. Linear rail machining centers are generally BT40 and BT50, which generally use belt type 8000rpm or direct drive type 12000rpm, and its torque is greater than BT30, so the cutting strength is not as good as that of vertical machining center.

The machining center is more suitable for curved surface machining, relatively heavy cutting, such as molds, steel and other machined parts, while the drilling and tapping center is biased towards light cutting, tapping small threads, and high speed, such as laptop shells, mobile phone shells, 3C products, non-ferrous metal types. -Shanghai Dingya Precision Machinery Everything is just to make good use of machine tools!

The drilling and tapping machine is derived from the machining center, and it is also a model in the machining center.

As the name suggests, the drilling and tapping machine is mainly to process holes, including drilling, tapping, boring, because the model of the drilling and tapping machine is small relative to the machining center, and it is a linear guide rail, and the bearing capacity is also inferior to the machining center, which is obviously better than the machining center in the field of hole processing, of course, due to the problem of machine tool structure, the rigidity of the drilling center is also worse than that of the machining center, and the milling performance is far lower than the processing capacity of the machining center, and its shape is similar to the form of a large turntable.

The machining center is mainly used for processing planes, curved surfaces and other shape equipment. In terms of the selection of tool magazines, the machining center is mainly a bucket hat type tool magazine and a disc tool magazine, while the drilling and tapping center is mainly a turret tool magazine and a turret tool magazine. In terms of rapid traverse speed, the drilling and tapping center adopts linear guide rails, and the rapid traverse speed is faster than that of the machining center.

The machining efficiency of the machine tool is obvious.

Under normal circumstances, manufacturers of production and processing centers will produce drilling and tapping centers, but manufacturers specializing in drilling and tapping centers will not necessarily save the production of other types of machining centers. The drilling and tapping center is essentially a model of the vertical machining center, because the drilling and tapping center itself is derived from the vertical machining center. So today, Taicheng CNC will take you to understand the similarities and differences between the two.

A machining center is a high-efficiency automatic machine tool composed of mechanical equipment and a numerical control system for processing complex shapes. I believe that everyone knows more about these, so I won't describe them more here. The "drill center" is analyzed as "drill" from the name

Drilling and milling or drilling, "tapping": tapping, "center": machining center.

The full name is roughly several: "drilling and milling and tapping center", "drilling and tapping center", "drilling and milling machining center", "drilling and milling center"). It is also derived from the traditional metal cutting machine tool - computer gong (machining center), so from the structural point of view, the drilling and tapping center and the high-speed machining center are the same, the drilling and tapping center and the high-speed machining center also have the function of drilling and tapping and high-speed milling, the advantage of the drilling and tapping center in "drilling and tapping" is better than that of the high-speed machining center, and the high-speed milling rapid moving feed is also faster than the flexible high-speed machining center, but the model is less and the stroke is smaller than the high-speed machining center, and the cutting strength is inferior to the high-speed machining center.

Summary. Both taps and machining centers can be used for drilling, but the drilling parameters may vary depending on the specific equipment and machining requirements. Generally speaking, the drilling and tapping rig is mainly used for drilling and tapping, and its drilling parameters mainly include drill bit diameter, drilling depth, drilling speed, feed rate, etc.; Machining centers, on the other hand, can perform more complex drilling with drilling parameters such as cutting speed, cutting depth, coolant flow and pressure, in addition to the above parameters.

Both taps and machining centers can be used for drilling, but the drilling parameters may vary depending on the specific equipment and machining requirements. Generally speaking, the drilling and tapping rig is mainly used for drilling and tapping, and its careful drilling parameters mainly include drill bit diameter, drilling depth, drilling speed, feed rate, etc.; On the other hand, the machining center Kuanyingfeng can perform more complex drilling operations, and its drilling parameters include cutting speed, cutting depth, coolant flow and pressure in addition to the above parameters.

I'm still a little confused, can you be more detailed?

In addition, the accuracy and efficiency of drilling and tapping machines and machining centers may also vary. The drilling and burning Huaili attack machine generally uses a single-edged drill bit, which has relatively low processing efficiency but high processing accuracy; The machining center can use a multi-edge drill bit, which is more efficient, but the machining accuracy may be affected. Therefore, the difference between the drilling and tapping machine and the machining center in terms of the number of drilling parameters mainly depends on the different design and use.

When choosing drilling equipment, you should consider the specific processing requirements and budget and other factors, and choose the most suitable equipment for you.

Hello, the drilling and tapping center is a high-speed CNC machine tool evolved from the machining center, which is very similar to the structure of the machining center, and can also be said to be a miniature version of the machining center. However, the drilling center runs at a very fast speed, usually reaching a speed of 48-60 meters. Theoretically, the drilling and tapping center is a high-speed machining center.

What is the difference between a drilling and tapping center and a high-speed machining center?

1. What are the advantages of drilling and tapping centers?

In the field of metal cutting, drilling, milling, tapping and other basic functions of processing in the vertical CNC machine tool has no problem, but with the manufacturing processing requirements are getting higher and higher, ordinary vertical CNC machine tools have become more and more difficult to meet the higher needs of customers, faster, higher precision mechanical equipment has been the popular demand, and the drilling and tapping center (also known as high-speed drilling and tapping center) can meet such requirements.

The X-axis stroke does not exceed 700mm and the Y-axis does not exceed 400mm. It can be said that the drilling and tapping center is born for small parts such as the 3C industry, the electronics industry, and medical equipment. Drilling and tapping centers are specially used for the machining of small parts or products, and they are extremely efficient, so they have become more and more popular in recent years.

2. What is the difference between a drilling and tapping center and a high-speed machining center?

From the structural point of view or from the perspective of spindle speed, the drilling and tapping center and the high-speed machining center are very similar. But in fact, there is a big difference between a drilling and tapping center and a high-speed machining center. The drilling and tapping center can be called the drilling and tapping center, of course, because of its high drilling and tapping ability, and the drilling and tapping center is better than the high-speed machining center in terms of drilling and tapping.

Tapping centers are also more "flexible" than high-speed machining centers, which means that the rapid feeds of tapping centers are faster than those of high-speed machining centers. There is another special point of the drilling and tapping center, that is, its flying saucer tool magazine, the flying saucer tool magazine tool change time is extremely fast, generally within seconds to complete the tool change, some only need seconds to complete the tool change, the tool change speed is much faster than the high-speed machining center. However, the drilling and tapping center is not omnipotent, its stroke is not as large as the high-speed machining center, and the cutting strength is not as good as the high-speed machining center.

In terms of the diversity of uses, the drilling and tapping center is also inferior to the high-speed machining center.

To be precise, the drilling and tapping machining center is not a high-speed machining center, the drilling and tapping center is a small drilling and milling center derived from the vertical machining center, which occupies a smaller area than the machining center and is smaller than the machining stroke of the machining center, which is suitable for processing some light and small metals, and is not suitable for heavy-duty cutting.

There are many types, mainly depending on what workpiece you are using to process, whether the machine tool is good enough, and whether you can use a high-efficiency drill bit.

1.Drill bits are generally divided into high-speed steel (HSS) and cemented carbide (Carbide) according to the materials we commonly use. If the machine tool spindle accuracy is good, the power is large, you can use alloy drill to improve the processing efficiency, if you consider the cost, the high-speed steel is more cost-effective, of course, the efficiency is relatively low, compared with the alloy drill bit efficiency is doubled than the high-speed steel drill.

Advantages of alloy drills: high hardness, wear resistance, high temperature resistance. Cons:

Hard and brittle, it is prone to breakage if used improperly.

2.Drill bits are generally divided into ordinary drills, shallow hole drills, deep hole drills, centering drills, etc. Needless to say, ordinary drilling is used to process ordinary holes, generally speaking, the hole drilled out of 12 with high-speed steel drill bit may be about 10 wire-20 wires larger, and the alloy drill will generally be a little larger, but it is generally very small, of course, in the case of good accuracy of the spindle of the machine tool, if the longitudinal runout of the machine tool is not good, what drill bit will appear to have a large hole.

Shallow hole drilling: when used on the machining center, indexable shallow hole drilling is generally used, that is, a drill bit with alloy inserts, and the use of this kind of drill generally requires the machine tool spindle to have an internal cooling device, otherwise the processing efficiency will be reduced.

Deep hole drilling: As the name suggests, it is a drill bit used to process deep holes, with a relatively large diameter and length, and generally has 2 guide edges on the side edge.

Center drill: It is used to prevent the position change during drilling during processing and to make positioning holes.

Centering drill: better positioning ability than ordinary drill bits, generally used to make centering holes or process thin plates. The difference with ordinary drill bits is that the grinding method of the drill top is different.

Reaming drill: The drill bit used to reaming the hole after drilling with the drill bit, there is no drilling top angle, and the reaming is generally in between, which is used with the reamer.

There are also many drill bits, like non-standard drill bits, each of which has its own purpose, mainly depending on what kind of drill bit you need for the workpiece you are machining.
