Machining itself is a type of manufacturing that is used to basically create objects out of metal. The workers involved in this process will literally cut away materials to alter the shape and appearance of the tool or item and it is known as one of the most effective methods of creating very fine and detailed items that might not be able to be created in any other fashion. It is an effective alternative to methods like casting and molding. This is also one of the most effective ways of developing the more specialized products and parts used in the aerospace industry.
One of the most useful machines for creating tools and materials in the aerospace industry are known as screw machines. These come in several varieties, including Turret and Swiss. The Swiss machines use precision parts that are generally the better of the two. It achieves much more precise results, which are clearly needed for the aerospace industry and their exacting standards.
The Swiss screw machines also come in two different varieties, namely automatic and CNC. The automatic versions function with a disc cam that rotates the tools. The CNC machine is controlled by a CNC unit. This also allows it to be able to run several operations on the same machine in a much faster time period. This also makes it incredibly cost efficient and has an accuracy level of 0.0002 to 0.0005 inches.
The very latest news is that now there are both CNC automatic lathe and CNC multi spindle machines. This is definitely something for your company to look into, since these multiple spindle machines could potentially lead to huge savings in productivity and other costs.
CNC Milling Machines:
Milling machines are generally used in the tool making process. They shape solid products by eliminating excess material to form a finished product. However, they can also be used to create materials for a variety of industries including the aerospace industry. They can slot cut, threading, routing, planning, and drilling. They can cut a wide variety of metals, as you might imagine, ranging from aluminum to stainless steel.
In addition to a cutting device, a typical milling machine will have a spindle axis that actually holds the cutter in place and can be adjusted to cut at varying speeds. Most of the work tables can move in two directions and are power-operated. Modern milling machines are also normally equipped with a self-contained electric drive motor and a coolant system.
The CNC is short for Computer Numerical Control. This enables the machine to be controlled digitally. It also enables the machine to contain up to 5 different axes to allow for more precision and greater flexibility. Since there is no need for a manual operator, these types of machines also eliminate the need for a human operator, saving money and preventing potential accidents.
Machining In The Aerospace Industry:
The aerospace industry demands precision and high quality. This is one of the major reasons and factors that has driven the development and advancement of these types of machines. Whether they are used to create actual highly specific tools that can then create parts and materials or if they are directly creating the parts and materials, the CNC types of machines are incredibly valuable and productive.
