Types of CNC Machining Operations

CNC machining is a manufacturing process used in a variety of industries, including automotive, aerospace, construction, and agriculture, and is capable of producing a range of products, such as automotive frames, surgical equipment, aircraft engines, gears, and hand and garden tools. The process consists of several different computer-controlled machining operations, including mechanical, chemical, electrical, and thermal processes that remove the necessary material from the workpiece to produce a custom-designed part or product. With our CNC machines, you can accomplish these processes with ease! In this article, we'll take a look at some of the most common machine CNC machining operations, including drilling, milling, and turning.

2, CNC milling process of CNC machine tools

3, CNC turning process of CNC machine tools

1, CNC drilling process of CNC machine tools

Drilling is a machining process that uses a multi-point drill to process cylindrical holes in the workpiece. In CNC drilling, CNC machine tools usually feed a rotary drill perpendicular to the surface plane of the workpiece to produce vertically aligned holes with a diameter equal to the diameter of the drill used in the drilling operation. However, angular drilling operations can also be performed through the use of specialized machine configurations and workpiece clamping devices. Operational capabilities of the drilling process include counter boring, countersinking, reaming and tapping.

2. CNC Milling Processes for CNC Machines

Milling is a machining process that utilizes a rotary multi-point cutting tool to remove material from a workpiece. In CNC milling, the CNC machine tool usually feeds the workpiece into the cutting tool in the same direction as the direction of rotation of the cutting tool, whereas in manual milling, the machine tool feeds the workpiece in the direction opposite to the direction of rotation of the cutting tool. The operational capabilities of the milling process include face milling for milling shallow, flat surfaces and flat-bottomed cavities on the workpiece, and peripheral milling for milling deep cavities (such as slots and threads) on the workpiece.

3. CNC turning process of CNC machine tools

Turning is a machining process that removes material from a rotating workpiece using a single-point cutting tool. In CNC lathe machining, a CNC lathe feeds a cutting tool in a linear motion along the surface of a rotating workpiece, removing material around the circumference until the desired diameter is reached, thus producing a cylindrical part with external and internal features such as slots, tapers, and threads. The operational functions of turning include boring, face machining, grooving and thread cutting. In the case of CNC mills and lathes, milling machines use rotary cutting tools and are better suited for machining complex parts. However, lathes use rotating workpieces and stationary cutting tools and are best suited for faster, more accurate manufacturing of round parts.
