In order to obtain many specific metal compositions, metals undergo certain processes. For products like machined investment cast parts, a process called machining is required after the part is cast. We've already discussed what machining is, but there are several different tools and processes in machining that are specific to the part and its purpose. Depending on what a machined investment cast part will ultimately be used for, the type of machining it undergoes can vary. Wondering what types of machining are available for your metal parts? Read on to find out more!
The techniques involved in the machining process vary between the different tools used for cutting. Sometimes machined investment castings require a certain texture or very specific dimensions, and in each case a different tool is used. Some different types of machining operations include turning, drilling, boring, reaming, and milling. In turning, single-edged cutting tools are used to remove excess material from rotating parts and create cylindrical shapes. In the process of drilling a round hole, which is similar, a curved tip is used to improve the accuracy of an already roughed hole. Reaming removes a small amount of excess metal from an already drilled hole, while milling is a rotary tool with multiple cutting edges used to create a straight surface.
Machined Investment Casting Applications
Investment casting is used in the aerospace and power generation industries to manufacture various components. Machining investment casting involves machining the part after it is manufactured so that it meets the exact specifications of the company. In these types of industries, it is important to ensure that any precise measurements are achieved in machined investment casting.
