CNC machining center is a high-efficiency automatic machine tool composed of mechanical equipment and CNC system, which is suitable for complex cnc machining parts. CNC machining center is also one of the most widely used CNC machine tools in the world.
1. Learn to live up and down.
Some people will say, is this not easy? Is it simple, but some people can’t do it well. Living also requires skill, and this does require accumulation of experience. Normally processed workpieces will be clamped with flat-nose pliers or three-jaw chucks, some will be clamped with pressure plates, and some workpieces will also need tooling to clamp. Due to different materials and different processing shapes, whether the clamping force and compression force are balanced will affect the accuracy of the workpiece processing and the deformation of the workpiece after processing. A colleague often uses flat-nose pliers to clamp the workpiece to make fine holes. Before loosening the pliers, the pass gauge can go down. When the pliers are loosened, the pass gauge cannot go down. This is that the clamping force is not well controlled. The clamping force is large, the workpiece is deformed, the clamping force is small, and the workpiece runs away during the milling process, which is not good.
2. Learn to align, score, and set the knife.
This is very basic, the basic skills of dry machining center.
3. Learn to grind the drill bit.
Dry machining centers often need to drill holes, and the drill bit must be worn. If not, you should still spend time practicing on the grinding wheel.
Tips for grinding the drill: the edge of the blade is flat against the wheel surface, and the drill shaft obliquely releases the angle of sharpness; grinding the back from the blade to the back, swinging up and down don’t warp.
4. Learn to read drawings.
The drawings must be read. The drawings are the language of the robot. Without understanding the drawings, there is no way to analyze the process, let alone programming. When looking at the drawings, you must be serious. First of all, you need to see whether it is the first corner drawing method or the third corner drawing method, and then see where is the reference, and there are some important dimensions, especially the geometric tolerances in the drawings.
5. Understand commonly used tool knowledge.
Be sure to understand the commonly used tools and their uses. Know what tools are used for what.
6. Understand common material properties.
does not need to be too deep, but you must understand the characteristics of common machining materials. For example, if you don’t understand the hardness of this material, the program you have written may not be reasonable for the speed feed.
7. Learn to program with computer software.
programming is divided into manual programming and automatic programming. Due to the complexity of the workpieces in the machining center, you still have to learn to program with computer software. You can learn mainstream software such as UG, PowerMILL, etc. If you want to learn UG programming, you can add QQ group 304214709 to receive UG learning materials and courses.
8. Learn to use measuring tools.
For the commonly used measuring tools, be sure to use them skillfully. Such as vernier caliper, micrometer, inner diameter table, depth ruler, etc.
