What is the main technical performance of CNC milling machine

Although the numerical control systems configured by various types of CNC milling machines are different, the functions of various CNC systems, except for some special functions, are basically the same.

1. Point control function.

This function enables hole system machining that requires high mutual position accuracy.

2. Continuous contour control function.

This function can realize the interpolation function of straight lines and arcs, as well as the machining of non-circular curves.

3. Tool radius compensation function.

This function can be programmed according to the dimension of the part drawing, regardless of the actual radius size of the tool used, thus reducing complex numerical calculations during programming.

4. Tool degree compensation function.

This function can automatically compensate for the length of the tool to adapt to the requirements of the tool length size adjustment during machining.

5. Proportion and mirror processing function.

The scale function can be executed by changing the coordinate value of the programmed machining program according to the specified proportion. Mirror machining, also known as axisymmetric machining, if the shape of a part is symmetrical with respect to the coordinate axis, then only one or two quadrants can be programmed, and the contours of the rest of the quadrants can be achieved through mirror machining.

6. Rotation function.

This function can be performed by rotating the programmed machining program at any angle in the machining plane.

7. Subroutine call function.

Some parts need to repeatedly process the same contour shape in different positions, and the processing program of a contour shape is used as a sub-program, and the processing of the part can be completed by repeated call in the required position.

8. Macro program function.

This function can use a total instruction to represent a series of instructions to implement a certain function, and can perform calculations on variables, making the program more flexible and convenient.

1.The working area of the workbench (length and width).

2.The maximum longitudinal and transverse stroke of the table.

3.Vertical travel of the table.

4. The number of t-row slots, slot width and slot spacing of the workbench.

5.Spindle bore taper, diameter.

6.The distance the spindle sleeve travels.

7.The distance from the spindle face to the table.

8.The distance from the spindle centerline to the vertical guide rail of the bed.

9.The distance from the side of the workbench to the vertical rail of the bed.

10.Spindle speed progression and range.

11.Table feed.

12.Spindle motor power.

13.Servo motor quota torque.

14.Machine dimensions. Wait.

According to the scope of the workpiece you are machining, each machine tool has a description of the main technical performance of the specific machine tool.

In addition to the characteristics of ordinary milling machine processing, CNC milling processing also has the following characteristics:

1. The adaptability and flexibility of parts processing are strong, and the parts with particularly complex contours and shapes or difficult to control the size can be processed, such as mold parts, shell parts, etc.;

2. It can process parts that cannot be processed by ordinary machine tools or are difficult to process, such as complex curve parts described by mathematical models and three-dimensional space surface parts;

3. It can process parts that need to be processed in multiple processes after a clamping and positioning;

4. The processing accuracy is high, the processing quality is stable and reliable, the pulse equivalent of the CNC device is generally high-precision, and the high-precision CNC system can reach, in addition, the CNC machining also avoids the operator's operation error;

5. The high degree of production automation can reduce the labor intensity of the operator. It is conducive to the automation of production management;

6. High production efficiency, CNC milling machine generally does not need to use special process equipment such as special fixtures, and only needs to call the processing program, clamping tool and adjustment tool data stored in the CNC device when replacing the workpiece, thus greatly shortening the production cycle. Secondly, the CNC milling machine has the functions of milling machine, boring machine and drilling machine, which makes the process highly concentrated and greatly improves the production efficiency. In addition, the spindle speed and feed speed of the CNC milling machine are continuously variable, so it is conducive to selecting the best cutting amount;

1. Many materials can be processed.

Now many manufacturing industries need to carry out the drilling work of stainless steel, aluminum alloy and other hardware materials, and if the CNC drilling machine is used for processing, only the tool can be switched reasonably according to the required processing material to complete the punching work, and the operation of the CNC drilling machine is very stable when punching, and the punching technology is also very superior.

2. It can be processed in batches.

Nowadays, the development of many manufacturing industries is very rapid, so a large number of parts and components need to be punched during manufacturing. The CNC drilling machine has multi-faceted, multi-sequence, multi-tool and other processing methods, which is enough to cope with large-scale parts punching operations, and the degree of automation is also very high.

3. High processing accuracy.

Since the CNC drilling machine is operated by intelligent applications, it can easily set various processing specifications, and its accuracy is very high when punching.

Among them, the lathe is known as the working machine of all equipment, and the general car is actually a horizontal lathe, and more than 70% of the objects to be processed are completed by the general car! It can be seen the status of the general car, in addition, I work in the school, the student internship is about 8 weeks, the general milling is about 4 weeks, and the equipment of the general car is about 6 times that of the general milling! In addition, when an individual is working, he can use the car resolutely without milling!

However, what is said above does not explain which type of work has high technical content, and it can only be said that the general car is more widely used than the general milling! Let's have more jobs! My knowledge is limited, please criticize and correct the inappropriateness!

This problem I come, to talk about the technical content of the car must be high in technology, people who have done the general car can basically do the general milling machine work, in turn have done the milling machine basically can not do the work of the general car, there is an old saying good, "learn to turn the pliers and the reium, go all over the world are not afraid", the general car people are basically let other machine tools will do a simple job, some people are not convinced to take CNC lathe and processing to say things, first of all, I tell you, the biggest difference between CNC and ordinary machine tools is a manual, a is computer automation, Completely two different things, no comparison, you really want to compare the technical content of the machining center than the CNC car I can only say that you are lonely and unheard, now CNC is a system engineering, CNC is mainly on Sun Shen Bureau is to do batch work, so if there are conditions, they are manipulators.

Operation, so you may also be able to operate the manipulator, or several CNC equipment, even if only do a number of filial piety control machine, the machining center is not an upgraded version of the milling machine, the machining center is also divided into milling center and turning center, if you insist on saying that the milling center is an upgraded version of the milling machine, then I also want to say that the turning center is an upgraded version of the lathe, so this is not much high, by the way, the machining center of the general enterprise is a milling center, well, I will simply say so much, if the technical content, Milling machine belongs to three-axis three-dimensional movement, lathe belongs to two-axis plane movement, milling machine contains a wider range of knowledge than lathes, but specific to what to do, especially some work with unique technical requirements to do well, such as slender shafts, lathes include technology has a unique place for this type of work. Generally speaking, milling machines have wide requirements for cutting knowledge, even if it is general turning and milling. If it comes to CNC, then CNC milling machine.

The technical content is definitely better than that of CNC lathes.

Deep, CNC milling machine plus a tool magazine is a three-axis machining center!

It's not easy to compare directly, they have different functions, and it depends on the technical requirements and complexity of the object (workpiece) you use to process it. If you are in a large machine.

The ** of Guda Machinery gantry milling machine is about 100,000-700,000 yuan per unit, and the ** of different types of gantry milling machines of Guda Machinery is also different. In terms of category, the form is divided into gantry fixed workbench mobile type (accounting for more than 90%) and gantry mobile type (also known as bridge type) according to whether the gantry is mobile or not. Bridge gantry milling is characterized by a small footprint, large bearing capacity, and a gantry travel of up to 20 meters, which is convenient for processing extra-long or extra-heavy workpieces.

According to whether the beam moves on the column, it is divided into two types: moving beam type and fixed beam type; The movement of the beam over the elevated bed is called elevated. The system is divided into ordinary type and numerical control type, and there are manufacturers who have developed digital intelligent gantry milling with one-click conversion of ordinary milling and CNC milling, which is more flexible and practical. Capacity, divided into light, medium, and heavy (super heavy)....

1. The main machine, the theme of the CNC machine tool, including the machine body, column, spindle, feed mechanism and other mechanical parts. Mechanical components used to complete various cutting operations.

2. The numerical control device is the core of the CNC machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, which is used to input the digital part program, and complete the storage of input information, the transformation of data, the interpolation operation and the realization of various control functions.

3. The driving device, the driving parts of the actuator of the CNC machine tool, including the spindle drive unit, the spindle motor of the feed unit and the feed motor, etc. Under the control of the numerical control device, the spindle and feed drive are realized by means of an electrical or electro-hydraulic servo system. When several feeds are linked, positioning, straight lines, plane curves and spatial curves can be processed.

4. Auxiliary devices, some necessary supporting components of the index control machine tool to ensure the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. Including hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC indexing heads, as well as tools and monitoring and testing devices.

5. Programming and other ancillary equipment can be used to program and store parts outside the machine.

CNC milling machine is also known as CNC (computer numerical control) milling machine. English means milling machine with electronic meter digital signal control.

CNC milling machine is an automatic processing equipment developed on the basis of general milling machine, the processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, the CNC milling machine with a tool magazine is also called a machining center.

There are various forms of CNC milling machines, and although different types of CNC milling machines are different in composition, they have many similarities. The following takes the XK5040A CNC vertical lifting table milling machine as an example to introduce its composition. The saw 040A CNC vertical lifting table milling machine is equipped with four 3mA numerical control systems, which are fully digital AC servo driven.

The machine tool is composed of 6 main parts, namely the bed part, the milling head part, the workbench part, the transverse feed part, the lifting table part, the cooling and lubrication part. The internal layout of the bed is reasonable, with good rigidity, the base is provided with 4 adjusting bolts, which is convenient for the machine tool to be adjusted horizontally, and the cutting fluid reservoir is located inside the machine base.

Turning and milling are the two most important cutting methods in machining.

Turning is to use a tool (turning tool) to move along the surface of a high-speed rotating workpiece to complete the machining, generally machining the rotary surface (outer circle, cone, round hole, thread, etc.).

Milling is the use of high-speed rotating tools (milling cutters) to move along the surface of the workpiece (can also be the movement of the workpiece) to complete the machining, usually used to process planes, complex contours, grooves, etc.

The machine tool used to perform turning processing is called a lathe, and the machine tool used to carry out milling processing is called a milling machine. Ordinary lathes and milling machines are manually operated when processing, and lathes and milling machines that are automatically processed by digital control technology are called CNC lathes and CNC milling machines.

CNC lathes generally have two coordinate axes, and the programming is simpler, and CNC milling machines generally have more than three coordinate axes, and the programming is more complicated.

The specific situation cannot be exhausted in a few words, please refer to:

Turning. Milling process.

CNC lathes. CNC milling machine.

Lathes can only process round things, while milling machines can process them from various angles. But it's not entirely true, and I don't know too much.

Lathes are also available with milling shafts, LGMAZAK
