Various Process Used In the Manufacturing of Precision Components
Precision components are made by precision engineering process, which falls under the field of electrical engineering, mechanical and optical engineering and electronics engineering. In precision engineering, machine components and fixtures are developed. There are many advantages in using precision engineering process to make Precision components:
- The process greatly diminishes the running cost and the initial cost of the components.
- The components made by this process work more smartly and efficiently and make precise movements without wastage of energy
- Precision components increase the lifespan of the machine and increase the flexibility to make additional fittings in the machines
- Due to the high quality of the component parts made by precision engineering, the need to take safety measure for the machine is greatly reduced. This is because these parts ensure that the machine always runs with optimum efficiency.
- The components are designed in such a way that making innovations and changes in them becomes considerably easy.
There are many processes involved in the manufacturing of Precision components. Some of the main processes are given below:
- Deburring: It is common knowledge that many industrial processes used in manufacturing units still result in the finished Precision components having protruding edges or ragged sides which may cause injuries. This is where the deburring method comes into play. It is responsible for the removal of these uneven surfaces. There are several methods to get the deburring process done, such as applications of highly abrasive cloths, abrasive surfaces and abrasive substances. These are rubbed against the uneven surfaces to remove the protruding surface and to polish the area. In some cases, an additional process of sanding becomes necessary where special machines are used to remove stubborn protrusions. Some manufacturing plants also use a high velocity heavy grinder to do the job.
- Chamfering: All products have to be of aesthetic value and precision tools are no different. To give the Precision components a complete appearance the edges have to be flattened and beveled to various degrees. This is done by the process of chamfering. This process is also done to connect two surfaces.
- Broaching: This is a very common and one of the most used processes in precision engineering. Special tools called broaches are used to remove unwanted metallic materials from the surface of Precision components. In CNC machines these broaches are mounted on computer controlled hydraulic arms to do the job. There are two kinds of broaching processes. The Linear broaching process is one in which the broach is used in a linear fashion against the surface of the required material to modify it. The rotary broaching process, which is comparatively less common, is all about pressing the broach when it is rotating to cut the material across an even axis.
- Milling: This is a common procedure used in the manufacture of high quality machine parts and components, especially using the CNC technologies and machines. In Milling, powerful rotary wheels are used to remove unwanted materials. The work piece is cut either along the circumference or along the corners.
- Cold forming: This is a highly efficient and fast manufacturing process in which the metal is molded at room temperature. This is also cost effective because the need for tools for material removal is negated. There are many benefits in using cold forming, it saves 70 percent of all materials, improves the features of the designed product, gives a surface finish of superior quality, greatly reduces the production cost and gives consistent result every single time.
