What are the methods of CNC instrument lathe processing

How about CNC machines? This question cannot be generalized and should be analyzed according to your specific situation. Here is a brief introduction to the characteristics of CNC CNC machine tools for your reference.

1. High processing accuracy and stable processing quality; 2. It can carry out multi-coordinate linkage and process parts with complex shapes; 3. When the processed parts are changed, generally only need to change the CNC program, which can save production preparation time; 4. The machine tool itself has high precision and rigidity, and can choose a favorable processing amount, and the productivity is high (generally 3 5 times that of ordinary machine tools); 5. The machine tool has a high degree of automation, which can reduce labor intensity; 6. The quality requirements for operators are higher, and the technical requirements for maintenance personnel are higher.

I have been engaged in the CNC industry for 10 years, large and small CNC have seen, the instrument lathe itself is the smallest machine of the lathe class, its activation efficiency is fast, usually is the processing of very small products and the amount is very large in the case of use.

With the change of the CNC industry, at present, many machinery have been modified into CNC, the cost is low and can save labor, and more importantly, the efficiency of the work is several times faster than the manual, now many small enterprises are winning by quantity, here most of them will use CNC instrument lathes as the main force of the company's operation.

The super do of CNC instrument is not complicated, and the general CNC are the same, some of the difference is that the style of modification is different, some are hydraulic (purely fully automatic, no personnel operation automatic feeding processing), some are semi-automatic (need someone to clamp, press to start), and there is a manual is the original machine has not been modified (that is, manual non-stop operation).

Now the instrument car can be said to be far beyond the original semi-automatic instrument car several times the function, the most prominent is the use of the design of the row of knives, so that the original can only process simple workpieces of the instrument car, now can also process some very complex products, the tool device can be installed with a 4 to 7 knives is not a problem, greatly the function of the instrument car to the limit.

The smaller the things, the easier it is to get started, and the fundamental center is the quality of the product, and the quality is the real driving force for an enterprise to survive!

CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system is able to logically process and decode programs with control codes or other symbolic instructions so that the machine can move and the parts are machined.

Compared with ordinary machine tools, CNC machine tools have the following characteristics:

High machining accuracy and stable processing quality;

It can carry out multi-coordinate linkage and process parts with complex shapes;

When the processed parts are changed, generally only need to change the CNC program, which can save production preparation time;

The machine tool itself has high precision and rigidity, and can choose a favorable processing amount, and the productivity is high (generally 3 5 times that of ordinary machine tools);

The machine tool has a high degree of automation, which can reduce labor intensity;

The quality requirements for operators are higher, and the technical requirements for maintenance personnel are higher.

CNC lathe is one of the most widely used CNC machine tools. It is mainly used for the cutting of the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces of arbitrary taper angles, the internal and external curved surfaces of complex rotation, cylindrical and conical threads, and can be grooving, drilling, reaming, reaming and boring.

CNC machine tools are automatically processed on the processed parts according to the pre-programmed processing program. We compile the processing process route, process parameters, movement trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet in accordance with the instructions and program formats specified by the CNC machine tool, and then record the content of the program sheet on the control medium, and then input it into the CNC device of the CNC machine tool, so as to command the machine tool to process the parts.

CNC lathes and turning centers are high-precision and high-efficiency automatic machine tools. Equipped with a multi-station turret or a driven turret, the machine tool has a wide range of processing technology performance, which can process linear cylinders, oblique cylinders, arcs and various complex workpieces such as threads, grooves, worms, etc., with various compensation functions of linear interpolation and circular interpolation, and play a role in the mass production of complex parts.

has good economic results.

The main machine, which is the main body of the CNC machine tool, includes the machine body, column, spindle, feed mechanism and other mechanical parts. He is a mechanical component used to complete various cutting operations.

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 the 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.

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

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

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

The CNC lathe is composed of a CNC device, a bed, a spindle box, a tool holder feed system, a tailstock, a hydraulic system, a cooling system, a lubrication system, a chip conveyor and other parts. CNC lathes are divided into two types: vertical CNC lathes and horizontal CNC lathes.

CNC lathe is a high-precision, high-efficiency automatic machine tool, and it is also the most used CNC machine tool, accounting for about 25% of the total number of CNC machine tools. It is mainly used for the processing of rotating body parts such as shafts and discs with high precision requirements, good surface roughness and complex contour shapes, and can automatically complete the cutting of cylindrical surfaces, conical surfaces, arc surfaces and various threads through program control, and can carry out grooving, drilling, reaming, reaming and other processing.

Because the CNC lathe has high machining accuracy, can do straight line and arc interpolation function, some CNC lathes also have the characteristics of non-circular curve interpolation function and automatic speed change function in the processing process, so its process range is much wider than that of ordinary lathes.

1.Rotary body parts with high precision requirements.

Due to the good rigidity of the CNC lathe, the high precision of manufacturing and tool setting, and the convenient and accurate manual compensation and automatic compensation, it can process parts with high precision requirements, and can even be grinded by turning.

2.Rotary body parts with high surface roughness requirements.

The CNC lathe has a constant linear speed cutting function, which can process uniform parts with small surface roughness. With the constant linear cutting function, the optimal speed can be used to cut the cone and end face, so that the surface roughness of the cut workpiece is small and consistent. CNC lathes are also suitable for processing workpieces with different surface roughness requirements.

The roughness requires a large part to use a larger feed, and the small part requires a small feed.

3.Rotary body parts with particularly complex contour shapes and difficult to control size.

Because the CNC lathe has the function of linear and circular interpolation, and some of the CNC devices of the lathe also have some non-circular curve and plane curve interpolation functions, it can process the rotary body parts with particularly complex shapes or difficult to control the size.

4.Swivel body parts with special threads.

The types of threads that can be turned by ordinary lathes are quite limited, it can only turn straight, tapered male and inch threads of equal leads, and a lathe can only be limited to processing threads of several leads. The CNC lathe can not only turn any straight and tapered threads and end threads of equal lead, but also turn pitch threads and high-precision threads.

To sum it up in one sentence: rotary body parts.

Multi-sentence explanation: What are rotary body parts? That is to say, parts that can be rotated around a certain axis, such as general shaft parts, disc parts, spherical parts, ellipsoidal rows, cams, etc., in addition, various threads can be turned, including tapered pipe threads.

Dear, the teacher will share with you the basic characteristics of CNC machining! The details are as follows: 1. First of all, the process content of CNC machining is more complex than that of ordinary machine tool processing! 2. The preparation of CNC machine tool processing procedures is more complex than the preparation of ordinary machine tool process procedures!

3.Dear, this is because there is no need to consider the problems in the processing technology of ordinary machine tools, such as the arrangement of steps in the process, the tool point, the tool change point and the determination of the tool route, etc., but it is necessary to seriously consider it when compiling the CNC machining process!
