The processing center integrates oil, gas, electricity and CNC, which can achieve one clamp at the same time for various complex parts, plates, shells, cams, molds and other complex parts. Ideal equipment for high-volume processing.
How is the treatment center facing the knife?
1. Return to zero (return to the origin point of the machine tool)
Before the knife, you need to perform Zero operation (return to the machine tool) to clear the coordinate data of the last operation. Note that all three axes of x, y and z must return to zero.
2. The spindle turns
Use “MDI” mode to rotate the main axis by input instruction code and keep the average rotation speed. Then change it to the “hand wheel” mode and the movement of the machine tool is moved by the conversion setting rate.
3.x with sword
Use a tool to touch the right side of the workpiece to clear the relative coordinates of the machine tool; The tool and the workpiece gently contact, lift the knife, note the x value of the relative coordinates of the machine, move the tool to half of the relative x coordinate, note the x value of the coordinate machine absolute and press (enter) Input coordinate system for then Essence
4. Y with sword
Use the tool to gently touch the front of the workpiece to clear the relative coordinates of the machine tool; Machine relative coordinate value, move the tool to half of the relative coordinate, note the Y value of the absolute machine coordinates, and press the input coordinate system input (input).
5.Z with sword
Move the tool on the workpiece on the surface from Z to zero, slowly move the tool to gently contact the surface with the workpiece, note the Z direction value in the coordinate system of the machine tool at present and press (enter) to enter the entry.
6. The main axis stops
First stop the spindle, move the spindle to the appropriate position, retrieve the processing program, and prepare for formal processing.
How does the processing center produce and processed are prone to deformation parts?
For rooms with poor light quality, poor rigidity and low intensity. For such parts, we must first understand the reasons for the deformation:
Stress deformation:
These pieces are thin.
Heating distortion:
The texture of the piece is thin and thin.
Vibration deformation:
Under the action of radial cutting force, workpieces are subject to vibration and deformation, affecting the size, shape, position accuracy and surface roughness of the workpiece.
Easy deformation parts processing method:
Easy deformation parts represented by thin parts can adopt small feed and high cutting speed of high-level processing shape to reduce the cutting force of the workpiece during processing. Thermal deformation of the part.
Why is the processing center knife passivated?
CNC tools are not as fast as possible. In fact, knife passivation is not everyone’s literal understanding, but the way to improve the life of the tool. Improve tool quality by flattening, polishing and burr removal. This is actually a normal process before the knife is ground.
▲ Sword passivation comparison
The knife will pass the sand wheel blade before the finished product, but the processing union of the grinding blade causes micro-gap in degrees. While the processing center is cutting at high speed, the micro gap will easily develop, which will accelerate the tool wear and damage. In modern cutting technology, the stability and precision of the tool have strict requirements. The advantages of knife passivation are:
1. Physical wear of the knife
During the cutting process, the tool surface will gradually be consumed by the workpiece. Tool passivation can help the tool improve rigidity and prevent the cutting performance of the cutting tool prematurely.
2. Keep the room soft
The blade of the knife and the blade may cause the knife to wear out, and the surface of the processing workpiece will become rough. After passivation, the tool blade mouth will become smooth, the phenomenon of collapse will also be reduced accordingly, and the smoothness of the workpiece surface will also increase.
3. Convenient Groove Crops
Tool groove polishing treatment can improve surface quality and crumbs. After passivation and polishing, the surface of the processing center leaves many small holes on the surface.
How does the processing center reduce the rough surface rough part?
Rough surface of parts is one of the common problems of CNC processing center, which directly reflects the processing quality. How to control the surface roughness of workpiece processing, we must first analyze the reasons why the surface roughness is first, including: knife marks caused by the grinding process; Processing surface between friction.
When the surface roughness of the workpiece is selected, it should meet the requirements of the surface function of the workpieces, but also consider economic rationality. Under the premise of satisfying the cutting function, the reference value of large surface roughness should be selected as much as possible to reduce production costs. The executor of the tool as the cutting processing center should pay attention to daily maintenance and grind in time to wholeheartedly avoid the surface roughness caused by the tool too dull.
What should I do after the treatment center?
The processing center processing process is pretty much the same in general.
1. Cleaning, the processing center should remove the chips and wipe the machine god in time after completing the cutting task, and use the machine tool and the environment to keep it clean.
2. Check and replace the accessories, first pay attention to the oil card on the guide rail. Check the condition of the lubricating oil and coolant.
3. The shutdown program should be standardized, and the power supply and total power supply of the machine tool operation panel should be turned off in turn. Under conditions without special circumstances and special requirements, the principles of manual, dynamic and automatic return should be followed. The processing center should have low speed first, medium speed, then high speed. Low speed and medium speed running time cannot start working after any abnormal situation without abnormal conditions.
4. Standardize operations. Safety assurance and protection devices on machine tools shall not be arbitrarily dismantled and moved. The most effective treatment is safe treatment. .
