CNC turning, an integral process in the manufacturing sector, and rivets, a vital type of mechanical fastener, are two areas that hold immense importance in various industries. In this article, we’ll delve into how these products are produced while focusing specifically on their diversity.
CNC stands for Computer Numerical Control, a technology used widely in machining processes. One such notable process is CNC Turning. It involves a cutting tool being moved parallel to the workpiece axis while the piece is rotating around its axis. This programming technique allows a detailed transformation of raw material into intricate shapes such as spheres, cones, complex multi-curved contours, etc., with absolute precision.
The first step in producing an item via CNC Turning begins with creating an accurate model or design of the desired product. This digital blueprint is created using computer-aided design (CAD) software. After approval, the CAD design is implemented to develop a numerical program. This program operates the machine’s movements during the turning process through a CNC operator who feeds the instructions into the CNC machine.
Next, the proper specifications are formatted, including speed, depth of cut, and feed rate, tailored according to the component’s intricacy and the material type. Once everything is set up accordingly, the chosen material block is fixed onto the machine, where it rotates at varying speeds. The programmed tools then carry out their designated job simultaneously, slicing off layers from the work-piece until the required shape and size are met with high precision making every detail perfect.
Switching gears to rivets, they come in various types each having unique features and utilized for specific purposes based on the stress resistance characteristics needed. They have been fundamental components connecting pieces of sheets or plates together but vary considerably depending upon their head style, size, length, and material.
A few commonly used types include solid rivets, semi-tubular rivets, blind rivets, drive rivets, and flush rivets. Solid rivets are the most traditional type and offer excellent strength while semi-tubular rivets are hollow at one end making them easy to install since less setting force is required compared to solid ones. Blind rivets are meant for areas with only one-sided access during construction as their installation happens from one side of the workpiece. Drive rivets have a cupped end which flares out when hammered while Flush rivets sit level with the surface providing smooth finishes.
Manufacturing these types of rivets begins by selecting an appropriate material suitable for the application where they will be used, typically materials like aluminium or stainless steel are chosen due to their durability and beneficial properties. The process continues by extruding long cylindrical bars from selected material and cutting those into desired lengths.
Next, forming the head of the rivet occurs in punches designed according to the type of rivet-head (flat, round, pan etc.) using various techniques such as hammering or squeezing the punches that carry kinetic energy transferred onto them through hydraulic, mechanical or pneumatic systems. In case of hollow rivets (semi-tubular or blind), an extra drilling operation is involved to create the cavity. After final inspection ensuring accurate size, shape and finish qualities, the finished items are cleaned and packaged ready for sale or distribution.
In summary, CNC turning and different types of rivets hold unique benefits exploited vastly across diverse industries. While CNC Turning ensures high precision in molding materials into intricate objects offering huge scope on creativity; Different types of Rivets provide rigidity, ease of installation and several other advantages essential in constructing enduring structures.
