Common Secondary Machining Processes In Plastics Manufacturing
The secondary machining technique is costeffective for producing workpieces made up of multiple procedures. During the machiningb process, a number of processes are carried out in a specific order to provide the best outcomes. Secondary machining operations come after primary production processes like CNC or injection moulding.
● Drilling
This secondary machining process, known as computer numerical control (CNC), uses a round cutter to drill holes in a workpiece. Although milling equipment can also be used, this operation uses specifically designed drill pressingmachines.
● Milling
A multi-point rotary cutter bends deep threads, gear teeth, or slots onto the workpiece during milling. A fining coat is applied to the workpiece during the injection moulding process thanks to milling, a secondary machining procedure.
The turning process can be carried out manually or automatically by rotating the workpiece while a cutting tool operates in a linear motion to create the final tube-shaped item. Using CNC enables greater production, consistency, and efficiency.
Surface grinding machining processes are used when injection moulding calls for a tolerance surface polish. Thanks to the powered abrasive paste, wheel, or belt employed in this procedure, the workpiece has a fine-tolerance finish.
Because an injection moulding process demands a tolerance surface finish, surface grinding machining processes are required. By utilising a powered abrasive paste, wheel, or belt, it delivers the workpiece a fine-tolerance finish.
Have you ever considered how grooves are made in bottles to allow for appropriate cap fit? Well, this is accomplished by tapping. It is the process that uses a conical thread or cylindrical cutting tool to help produce grooves on the inside surface of the drilled hole. Tapping can be easily programmed into a CNC lathe, resulting in a very efficient and straightforward threading procedure. This gives the artwork a final, conclusive aspect that will help the viewer understand its intended purpose.
