What to pay attention to in the process of CNC lathe processing parts

How to receive machining orders, the factory wants to continue to output production capacity, it is not so easy. Each machining order item is composed of a series of factors, such as: workmanship, material, technical requirements, drawing details, unit price, delivery time, and business area.

Therefore, if you want to get orders, there are mainly these ways: 1. Widely get acquainted with industry procurement network resources 2. Participate in offline procurement and supply docking activities 3. Find purchase orders on industry-related platforms or **, such as: 168, Haizhi**, Made-in-China.com, Gaishi.com, etc.

Several platforms have their own focus: 168 and China's manufacturing network of the industry is more, Haizhi ** is a professional non-standard parts order**, Gaishi is only for the automotive industry, if only do non-standard parts....

The first is the accuracy of the tool, and then according to the process to take the appropriate tool, if the parts processing requirements are too high, it is best to use the tool that matches the material, pay attention to the programming, go to the route, special surface to pay attention to the calculation.

In the process? Of course, it is necessary to pay attention to whether there is interference between each knife, the length of the knife, the direction of the knife and the direction of rotation of the workpiece. The setting of the tip radius. Whether there is any abnormal noise during processing. It's a lot, and the main thing is that experience is everything.

At the beginning, you must pay attention to the tool, if it is right or wrong, the following are all wrong, and it is best to simulate the next before starting to cut.

It is necessary to pay attention to the first return to zero and then the tool, and there is that the program can not have errors, try to simulate it first, and there is the speed of the lathe, depending on what to do, whether to make plastic or iron.

The most basic thing to do a lathe is a knife. This is very important, if the knife is sharpened well, it is easier to pick up things, and then it is safe. Safety first. Complete!!

Shape single. 1. Parts with simple appearance and large margin are not suitable for CNC machine tool processing (not that they cannot be done, and they cannot reflect the advantages of CNC machines).

Generally suitable for CNC machining parts, there are the following characteristics:

1. Multi-variety, small-batch production parts or parts in the trial production of new products.

2. The shape is complex, the machining accuracy is high, the manufacturing precision is high, the tool is accurate, and the size compensation can be easily carried out, and the general machine tool cannot process or it is difficult to ensure the processing quality of the parts.

3. Parts with small surface roughness value.

4. Parts with complex contours and shapes. Any plane curve can be approached by a straight line or arc, and the CNC machine tool has the function of arc interpolation, which can process parts with various complex contours.

5. Shells or box-shaped parts with non-open inner cavities that are difficult to measure, difficult to control feed, and difficult to control size.

6. Parts with multiple processes such as milling, boring, countersinking, reaming or tapping must be completed in one clamping.

1. When the user uses the machine tool, it is not allowed to change the parameters set by the manufacturer in the control system at will. The setting of these parameters is directly related to the dynamic characteristics of the individual components of the machine. Only the value of the gap compensation parameter can be adjusted according to the actual situation.

2. The user can not change the machine tool accessories at will, such as using the hydraulic chuck beyond the provisions of the manual. When setting up accessories, the manufacturer fully considers the matching of the parameters of each link. Blind replacement causes mismatch of parameters in various links, and even causes unpredictable accidents.

3. The pressure of using hydraulic chuck, hydraulic turret, hydraulic tailstock and hydraulic cylinder should be within the allowable stress range, and it is not allowed to be arbitrarily increased.

At all stages of CNC machine operation, there are points to pay attention to.

First, the CNC lathe program input stage

1. The program input should be correct to avoid the wrong input of letters, numbers and symbols.

2 The program input should conform to the system format.

Second, CNC lathe parts processing operation preparation stage

1 Check whether the CNC system has returned to the reference point. Picoascending state.

2. Install the turning tool, and confirm that the tool position installed by the turning tool is consistent with the tool number required for programming in the program1

3 pairs of knives. (The end face and outer circle of the part should be manually machined with a turning tool.) )

4. After the turning tool is completed, the correctness of the tool setting should be confirmed, and the accuracy of the finishing turning tool should be confirmed.

5 Move the turning tool to a safe position for the programs "dry" and "prt".

6 Turn off "dry" and "PRT" to see if they are closed!

3. CNC lathe parts processing operation stage

1 Carefully check and confirm whether it is in line with automatic processing operation mode 1

2. Master and flexibly use the use of the magnification adjustment switch. Before the program starts, stops in the middle of the program, and other features.

In all cases, the magnification adjustment switch should be set to zero for observation and safe operation.

3 If you use the zero offset g54 parameter, you should confirm whether the value of the parameter is correct! Whether the procedure corresponds to 1

4 After the parts have been roughed and semi-finished, the dimensions of all levels are measured correctly. (Press the manual key at this point.) )

5. Xiaojube will determine a reasonable value of the measured size, adjust the value of G54 parameter X, and compensate the data.
