Metalworking tools come in a wide variety of models. If decades ago you would only see some basic non electric tools workers used to kill their time with, these days you can see robotized machines that are just as good or even better and more precise than humans.
Plate rolls for instance are very common, especially metal is highly commercialized in sheets. The most modern such machines include an automatic balancing system and hydraulic cone rolls. They also come with an emergency safety system, in case the worker dealing with them encounters problems. Radial arm drills are also very efficient metalworking tools that take away one responsibility off the workers' back. Years ago, workers have to perform manual drills. Even when they had the right tools, they still had to choose and make the holes themselves. These days, radial arm drills are programmable intelligent machines that only need programming. Basically, a professional engineer can set up the number of holes and the distance or the period of time between two holes. Then, the job is done by the machine, simple like that.
Milling machines are part of the heavy tools category. A milling machine does the job of 7 workers and it never needs to rest. Such machines are recently brought into the metalworking industry and their prices fit with their importance. They can be as expensive as a house. The modern milling machines have independent powered parts, in order to maintain integrity. Therefore, during troubleshooting, the working parts can go on while the damaged one is getting repaired. The same category includes the hydraulic presses. The RK models are the newest metalworking tools on the market. They have 10 to 20 horse-powers and a 100 to 150 tons capacity. In order to help you understand their power, you should know there still are cars manufactured in the 70's that have less horse-powers than a hydraulic press.
CNC lathes are modern micro panthers for production environment or training schools. Therefore, they are created to resist for tests and heavy work. They may come with up to 5 motors and various other smaller engines. CNC milling machines are also one of the newest and most important metalworking tools. The modern machines come tunned with chip augers or coolant wash down.
The prices for these modern tools may be exorbitant. They are obviously intended for major industries who can afford such huge numbers. For instance, the CNC machines can be purchased for around $50,000. Even the daily rent of over $1,000 is worth considering. What makes them so important? In the long run, they have more advantages over workers. They don't need breaks, sleep and they don't ask for monthly wages. In years, they are both more effective and lower in costs. Besides that, although it is said that a machine can never be better than a human, the repeated precision of these professional machines comes to argue against that fact. No surprise the top manufacturers opt for them instead of investing in training and hiring new workers.
