Drilling plays a vital role in automobile manufacturing. Hundreds of holes must be drilled for each manufactured vehicle, including holes in the drive shaft, engine block, airbag propellant chamber, camshaft, and other internal engine parts. In any auto parts production line, the conveyor belt is running uninterrupted, and efficient drilling equipment is a key aspect of profitability. The spindle is not drilling holes every minute, or the chips formed by drilling are not effectively evacuated, which is a minute of wasted money. Manufacturers must use drilling equipment because they can greatly improve the efficiency of making holes. Innovative technology is now available, which can be seamlessly integrated into the process without shutting down production.
Applying drilling equipment to automobile manufacturing
In the past, all large-scale and high-volume automotive metal cutting and drilling operations were performed through transmission lines on dedicated machines. These machines set the running speed through large chains, which transport parts between processing stations and wait there to perform operations. A certain number of parts can be drilled in a day; in addition, if one machine fails, the entire production line will be shut down. There is no advantage in developing cutting or drilling tools that can speed up the operation, because the production line can only run at the specified speed.
This outdated method of automobile manufacturing continued throughout the 1970s and 1980s, but with the rise of numerically controlled (CNC) machine tools, it gradually began to change in the 1990s. Today's modern car manufacturers are using flexible CNC drilling equipment. If a part can run faster on one device, it can speed up the connection to the next device, and perhaps gain an advantage, which ultimately translates into higher revenue. With these new transmission lines operated by CNC, manufacturers can become more flexible, make changes and take advantage of any new tools that appear. They can use tool innovation to help them increase production and make more money.
