In the factory, CNC treatment centers are mainly used for molds such as molds, inlaid and treatment. The quality of mold and inlaid directly determines the quality of the moldy mold. The quality of the public treatment in copper directly restricts the impact of the EDM treatment. The key to the guarantee of the quality of CNC treatment is preparation before treatment. team and colleagues.
流 CNC treatment process
1) Read drawings, program invoices
2) Transfer the program corresponding to the machine tool
3) Check the program header, cut the settings, etc.
4) Determination of the size of the treatment and balance of parts
5) Reasonable pliers for parts
6) Precision search
7) precise establishment of the coordinates of parts
8) Selection of reasonable knives and cutting parameters
9) a reasonable tightening of tools
10) Safety test cutting method
11) Observation of the processing process
12) Adjusting the cutting parameters
13) Back time between problems and corresponding staff during treatment
14) Testing the quality of the part after treatment
项 Precautions before treatment
1) For the new model, the processing scheme must meet the requirements and the data are clear;
2) The part has the qualified logo of the quality department.
3) After receiving the program’s bill, check if the part of the part is consistent with drawing of the drawing.
4) See each of the requirements on the program form.
5) Depending on the materials and the size of the part, judge the programmer’s reasonable character to open the thickness or the light knife program. part processing accuracy.
事 Precautions for the installation of the part
1) When you keep the part, pay attention to the code’s code position and extension of the thread bolt on the card.
2) Copper is generally machined for locking plates.
3) For the collection situation of several copper materials in a single card, check the direction correctly and if each copper is processed.
4) Depending on the form of the list of programs and the room size data, the part must be noted. He must check the scattered graphics and graphics on the program list.
5) When installing the part, you need to check if the part of the part meets the program’s size requirements.
6) The bottom of the room should be cleaned before the machine is cleaned. Part oils and surfaces are used to push the edge of wool and damage.
7) When code codes, make sure that the code is not injured by a knife and can communicate with the programmer if necessary. At the same time, if the bottom is amortized at the bottom, the code must address the position of the PAD to reach the objective of the balance of the force.
8) Use a tiger pliers to install the depth of the treatment of the knife to prevent the clip position from being too long or too short.
9) The screw must be included in the T blocking and the screw should not be used.
10) When you define the depth of Z, you should clearly see the position of the Single Touch program and the highest point data of Z. After losing the data in the machine tool, you must check again.
的 Precautions for the installation of knives
1) If you need to put a firm pliers, so as not to be too short in the handle.
2) Check if the knife should meet the requirements before each cable. The handle collided.
3) In the case of a deep treatment depth, you can contact the programmers. deeper position.
4) When you use the extension, you should particularly understand the depth of the knife and the length of the knife.
5) Before the knife head is installed on the machine, the cone is adapted to the position, the cleaning cloth is cleaned and the corresponding position of the cover of the knife-tool knife is also cleaned to avoid accuracy D ‘Impact of iron welds and damage the machine tool.
6) Usually, the knife length is used to use the tip of the knife (the stab situation in the knife in special circumstances).
7) When the program is interrupted or again, you must pay attention to the depth of the depth to the previous one.
8) The rotary and dismantled knife head.
件 Correction to find the precautions of the part
1) Pay attention to verticality when the part is dragged, then slide it, then drag the vertical edge.
2) When the part is divided, it is necessary to check it twice.
3) After the number of bumps, the size of the appearance and the size of the bulk diagram must be provided according to the program’s bill.
4) All parts must be used in the average method, and zero positions must also be divided alongside the room, then moved to the edge. If the unilateral number must be taken in specific circumstances, the production team must be confirmed by the production team. After the number of unilaterals, do not forget to compensate for the radius of the bar in the compensation.
5) The zero entrance to the center of the room must be the same as the central central center in the center of the three axes of the workstation.
项 Precautions for the processing process
1) When the balance of the upper surface of the room is too large, when the amount of handmade gongs is used to eliminate the balance, do not forget not to depth.
2) The most important thing for treatment is the first knife, because if you are careful and checks, you can know if the knife is completed, the diameter of the knife, the program, the speed, etc. To avoid damaging the part, tools and machine tools.
3) Try to cut the program according to the following tracks: a) The first height is the maximum increase of 100 mm and use the eyes to feel correct; suspended; d) Check if the remaining route and program are correct; The tool is very close to the surface of the room, it can be stopped and the remaining route of the Z axis must be checked. g) After treatment of the cut, the cut is smooth and stable, the control is adjusted in the normal state.
4) After entering the program name, copy the program name to the screen with a pen, then check the program’s bill. And sign the processor on the program form.
5) In principle, when the room is tough, NC technicians do not leave. inspection.
6) When they do in the middle of the race, CN NC technicians should pay particular attention to where they are not open when thick to prevent the knife from hitting this area.
7) Program cut. If the procedure is interrupted during treatment and it is a waste of time from zero, it must be notified to the team leader and the programmer to modify the procedure and cut the part.
8) The program is abnormal. If there is a different situation in the program and is not sure, you can hang up to observe the process, then decide the next one.
9) During the processing process, the speed and speed provided by the teacher can be adjusted if necessary depending on the situation. However, special attention must be paid at speed when the small copper is open and rough, so as not to open the part due to the oscillation.
10) During the part processing process, NC technicians should check with the dispersed card to see if there are abnormal conditions. There is an error.
11) When processing tools more than 200 mm long, you should pay attention to the amount of margin and the knife depth speed, speed of speed and other problems to avoid swinging the knife. The local position must be checked.
12) For the diameter of the detection of the tool on the program, the operator must be serious and responsible. to the person responsible for the group or to change the knife.
13) When the tool-tool is automatically functional or free, the operator must go to the workstation to find out more about the remaining treatment programming, prepare and grind the appropriate tool for the next treatment to avoid Stop.
14) Process errors are the main reasons for a waste of time: errors using inappropriate knives, processing errors, loss of time without processing or non -computer processing and inappropriate processing conditions (a vacuum knife Too slow, an empty knife, the vacuum knife, the knife is too dense, too slow, too slow, etc.), the above incident can be connected during programming.
15) During the processing process, you should pay attention to the wear of the tool.
项 Precautions for treatment
1) Confirm each program and each instruction required by the program.
2) Once the treatment is completed, it is necessary to check if the appearance of the part meets the requirements. in time.
3) See if there are anomalies in each location of the room.
4) The person responsible for the group must be informed under the large room.
5) Pay attention to safety when the part is placed.
的 The quality of the surface of the different lights of the treatment accuracy deals with the accuracy of the treatment accuracy:
1) MODEN, Inlaid 2) COPPER GONG 3) Avoid empty positions in the points and other places. used as much as possible.
▌ ▌
1) Confirm the functioning of the work, including treatment conditions, mold conditions, etc.
2) Confirm if the work is normal.
3) Other transfer and confirmation, including drawings, program invoices, tools, quantity, lighting, etc.
▌ Organization of the workplace
1) Run according to 5S requirements.
2) Classifications of tools, quantities, lights, parts, tools, etc. are carefully placed.
3) Clean machine tools.
4) Clean on the ground floor.
5) Back-Warehouses processed tools, inactivity tools and measurement tools.
6) Send the inspection or documents from the corresponding ministry for treatment.
