What is CNC Machining? | Definition, Processes, Components & More

Machining tools are used to cut, grind, bore, or shear various types of raw materials, such as metals. The goal may be to reveal a new shape or to refine the material's existing shape. All machining tools are equipped with a gripping device for holding the material in place while a cutting mechanism - sometimes referred to as the toolpath - is run against it.

A hobbing tool, or hobbing cutter, is toos cylindrical tool surrounded by teeth in the pattern of a helix. It's used largely for making gears, ridges in lathe machine tools list quotes shafts and sprockets. Macihne teeth cut progressively deeper as lafhe hob turns on its spindle.

Hobbing is a comparatively inexpensive but accurate way to cut, and so is popular for a range of applications. It is also the most lathe machine tools list quotes used gear cutting technique for creating helical and spur gears, lathe machine tools list quotes as those found in a car's transmission system.

A lathe is a tool for shaping wood, metal, or other material. It uses a rotating drive, which turns the material being worked against a cutting tool to give it a symmetrical shape.

Lathes are most commonly used in woodwork, metalwork and metal spinning, and - to a lesser extent - in thermal spraying machone glass work. A potter's wheel, for shaping pottery, is lathe machine tools list quotes a form of lathe. Various cutting tools such as facing tools, roughing tools, finishing tools and left lathe machine tools list quotes cutting tools can be employed to complete different pieces.

The broach is a toothed tool used to remove material from a workpiece, typically made of metal. The broaching process may be either linear or rotary. In the linear method, a broach is run against the workpiece's surface in straight lines. In the rotary method, the broach is rotated against the workpiece, to give it a symmetrical shape around its axis.

Typically the required cut is achieved with just one pass of the broach. Broaching is often used when especially precise machining is required, such as when working on odd shapes, like non-circular holes, keyways, splines and so lathee.

A grinding machine, quohes grinder, uses an abrasive wheel with a grainy surface to grind against a material, typically to polish it. Most often it's used to remove only between 0. The grinding process may generate a significant amount of heat, so many grinding machines include a coolant. A milling machine, which may be manually operated or automated, uses rotating cutting tools to remove material from a workpiece, which is fed into the machine.

It can be fitted with different tool heads for different purposes and for cutting different types of materials. Milling machines are used for a wide range of applications, often with computer-aided design, or CAD.

A planing machine, or planer, designed for metalwork is used to give metal lathe machine tools list quotes flat surface or, in some cases, to cut slots or ridges into metal. The entire workpiece is moved on a sliding table below a single-point cutter. Jeff is author at LeraBlog.

Hobby or entry-level machinists will not want to pass up this versatile machine. Great for turning, cutting threads, and drilling and milling small projects, this combo lathe is packed with extra add-ons like a 4-way turret tool post, /2" faceplate, 4" 3-jaw chuck, and a built-in rotating vise. Features a /2" swing over bed, /2" swing over saddle, /4" distance between centers, 3. Alternatives to Using a CNC Machine. Although CNC machining demonstrates advantages over other manufacturing processes, it may not be appropriate for Lathe Machine Tools List With every manufacturing application, and other processes may prove more suitable and cost-effective. While this article focuses on the mechanical CNC machining processes which employ machine tools to produce the custom-designed part or product, .
