数控机床加工需要掌握的基本知识

来源:http://www.jnhjgs.cn     发布时间:2020-05-18 13:53:40    点击:

数控加工是由机械设备与数控系统组成的适用于加工复杂零件的率自动化机床。数控加工也是目前世界上产量,应用更广泛的数控机床之一。它的综合加工能力较强,工件一次装夹完成较多加工内容,加工精度高,设置有刀库,适用于形状复杂,精度要求高的单件加工或中小批量多品种生产。
CNC machining center is a high efficiency automatic machine tool, which is composed of mechanical equipment and CNC system, and is suitable for machining complex parts. CNC machining center is also one of the most widely used CNC machine tools with the highest output in the world. Its comprehensive processing ability is strong, the workpiece can be clamped at a time to complete more processing contents, and the processing accuracy is high. It is equipped with a tool magazine, which is suitable for single piece processing with complex shape and high precision requirements, or small and medium batch production of many varieties.

对于刚刚接触数控加工或致力于在这一行业发展的数控朋友来说,应该掌握哪些基本知识呢?今天按小编我的经验给大家列举一下。只有不断地提高自己的技术,才会在这个行业内更好的发展,工资也会有相应的提高。(当然技术好,工资也不见得高,这个有时也很无奈。)
What basic knowledge should a NC friend who has just contacted NC machining center or is committed to the development of this industry master? Today, I will give you a list of my experience. Only by constantly improving their own technology, will better development in this industry, wages will also have a corresponding increase. (of course, the skill is good, and the salary is not necessarily high, which is sometimes helpless.)

1.学会上下活。
1. Learn to live up and down.
有人会说,这也不简单吗?简单吗,可是就有人做不好。上活也是需要技巧的,这个确实需要经验的积累。一般加工的工件,会用平口钳或者三爪卡盘夹住,有的用压板压住,有的工件还需要做工装来装夹。由于材料的不同,加工形状的不同,对于夹劲的大小,压劲是否均衡,都会对工件加工的精度,加工后工件的变形有影响。经常有同事用平口钳装夹工件做精孔时,松钳子之前通规能下去,等松开钳子,通规下不去了,这就是夹劲大小没有掌握好。夹劲大了,工件变形了,夹劲小了,工件在铣削的过程中跑了,都不好。
Someone would say, isn't that easy? It's easy, but some people can't do it well. It also needs skills to live. It really needs experience. Generally processed workpieces will be clamped with flat pliers or three jaw chuck, some with pressing plate, some workpieces still need to be clamped with tooling. Because of different materials and different machining shapes, the accuracy of workpiece machining and the deformation of workpiece will be affected by the size of clamping force and the balance of pressing force. There are often colleagues who use flat tongs to clamp workpieces for fine holes. Before loosening the tongs, the Tong gauge can go down. When loosening the tongs, the Tong gauge can not go down. This is that the clamping strength is not well controlled. The clamping force is large, the workpiece is deformed, the clamping force is small, and the workpiece runs in the milling process, which is not good.
2.学会找正,分中,对刀。
2. Learn to align, divide and align.
这个是很基础的了,干加工的基本功。
This is very basic. It is the basic skill of the machining center.
3.学会磨钻头。
3. Learn to grind the bit.
干加工,经常需要打孔的,钻头肯定要会磨的。如果不会的话,还是应该花时间在砂轮上多练习的。
Dry machining center, often need to drill, the drill must be able to grind. If not, you should spend more time on the grinding wheel.
磨钻头口诀:刃口摆平轮面靠,钻轴斜放出锋角;由刃向背磨后面,上下摆动尾别翘。
The pithy formula of grinding bit: the cutting edge shall be leveled and the wheel surface shall be lean, and the cutting axis shall be inclined to set out the front angle; the back shall be grinded from the cutting edge to the back, and the tail shall not be tilted up or down.
4.学会看图纸。
4. Learn to read drawings.
图纸肯定要会看的,图纸是机械人的语言。看不懂图纸,就没有办法分析工艺,更别说编程加工了。看图时一定要认真,首先要看看是角画法还是第三角画法,然后看看哪里是基准,还有一些重要的尺寸,尤其是图纸里的形位公差,更得注意。
Drawings must be able to read. Drawings are the language of robots. Do not understand the drawings, there is no way to analyze the process, let alone programming processing. When you look at a drawing, you must be careful. First, you need to see whether it is the first angle drawing or the third triangle drawing, and then you need to see where the datum is. There are also some important dimensions, especially the geometrical tolerance in the drawing, which should be paid more attention to.
5.了解常用的刀具知识。
5. Understand common tool knowledge.
对于常用的刀具及刀具的用途,一定要了解。知道什么刀具用来做什么。
For commonly used tools and their use, it is necessary to understand. Know what knives are used for.
6.了解常见的材料特性。
6. Understand common material properties.
不需要太深入,但是对于常见材料的特性一定要了解。比如你不懂这个材料的硬度,你编出的程序,给出的转速进给可能就不合理。
It doesn't need to be too deep, but it's important to understand the properties of common materials. For example, if you don't understand the hardness of this material, the program you compiled and the speed feed given may not be reasonable.
