At present, the automation of grinding machines is getting higher and higher, and automation has become a hot spot in the future development of grinding machines. But in the process of pursuing automation, the first thing to be clear is what is the purpose of achieving automation? The answer is nothing more than ensuring quality while maximizing production costs. There are two main factors to consider, first the machine tool itself, followed by the machining process.
The degree of automation achieved is very high for the machine itself, not all devices have these features. The machine tool needs to have a modular design to meet the needs of different users for flexible processing. In addition, the machine tool needs to have a very high computing speed, as well as a very wide range of interfaces to enhance the match with the automation system.
In addition, the machining process is equally important for automation systems. What automation is to achieve is an unmanned operation. From feeding to processing, each step needs to be manually detected in real time. If the target is not achieved, how to intervene in the machine to make adjustments? We divide this process into pre-process, in-process and post-process, ie pre-grinding, grinding and grinding. The purpose is to be able to carry out stable and reliable production. If there is a problem in any link, the machine automation cannot be realized. machining.
At present, the most demanding for mass production is the automotive industry. Therefore, the requirements for automation are also very high. For example, Jingzhou Henglong, the largest manufacturer of automotive power steering gear in China, produces about 100,000 to 200,000 pieces per year. For the products, they use the TSCHUDIN 3-in-1 grinding machine under the company. The machine is equipped with a knife loading and unloading device, equipped with MARPOSS pre-measuring device, online measuring device and post-grinding measuring device. The whole production process control is truly automated. Production, the processing that originally required 3 times of clamping is combined into one clamping, and the processing cycle is shortened by more than 5 times.
In the global market, especially in the Chinese market, an important basic feature for any fully automated grinding machine is to have a digital control system. Digital control systems are a prerequisite for automated grinding machines. After the CNC system, other components are needed, such as optimized software and accessories such as measuring systems, dressing systems, and cooling systems.
In general, grinding is a precision machining that guarantees the final process size and precision in machining, which requires high manufacturing and assembly accuracy. The demand for grinding machines in modern manufacturing is not limited to this. It also requires a high degree of automation of the grinding machine, but if someone asks what kind of function the grinding machine has, it can be called an automatic grinding machine because the grinding process varies widely. I think that answering this question can't be started with the function or equipment of the machine tool, but should start from the purpose of automation. Its purpose is nothing more than four kinds: first, automation to achieve the precision that artificial (or unskilled mechanic) can't achieve; secondly, automation to achieve Product accuracy can not be achieved by manual; third, automation to achieve efficiency that is difficult to achieve by humans; Fourth, automation to shorten the time required for manual setup, adjustment and loading.
Automation is not the purpose, digital control system, automatic detection device, automatic compensation system, automatic loading and unloading, etc., depending on the processing technology, manufacturing precision and production efficiency of the product. Due to the development of precision casting and forging processes, the scale of production of civilian products, and the increasingly fine division of socialization, people's requirements for automation of grinding machines will become higher and higher.
Aluminum Coil i is disposed rolling and bengding angle. Aluminum coil is widly used. The checker plate includes various kinds of tread.Normally there are big five bar,small five bar,two bar,stucco,,pointer,diamond and so on.Five bar Aluminum Sheet with great antiskid property and widly used on the floor.
The surface of aluminium sheets can be treated as smooth,or big five bar, small five bar, two bar, diamond or needle embossed. And also can be mill finish or bright finish The width is from 1000mm to 9000mm and the length is from 2000mm to 6000mm. We can also cut according to customers' special demands.The temper of the alloy is HO H12 H14 H22 H24 H18 H32. The payment we can accept include 30%T/T as deposit and the balance after the receipt the copy of the B/L.
