Seven common methods of forging processing

Forgings are processed in a variety of ways, with different shapes and structures commonly used. There are turning, drilling, boring, planing, broaching, milling and grinding. Although there is much in common in the principle of forging. The cutting motion form is different, but because the machine tool and tool are different, so it has its own process characteristics and application range.

First, turning

English name: turning, definition: workpiece rotation as the main motion, turning tool for feed motion cutting method. The main movement of turning is the rotation movement of parts, especially for machining rotary surface, and the linear movement of the tool is the feed movement.

Two, drilling

English name: drilling, other names: drilling, definition: drilling tool in the workpiece relative to the movement and axial feed motion, the method of machining holes in the workpiece. Drilling is one of the most basic hole processing methods. Drilling is often done on drill presses and lathes, but can also be done on boring and milling machines. Commonly used drilling machine are bench drilling machine, vertical drilling machine and radial drilling machine. It is much more difficult to drill a hole than to turn an outer circle, and some special problems are caused by the fact that the bit is working locally on the surface.

Three, boring

Chinese name: boring English name: Boring Other names: boring definition: boring cutter rotation for the main movement, workpiece or boring cutter for feed movement cutting method. Boring machining mainly in the milling and boring machine, boring machine.

Four, planing

Chinese name: planing English name: planing; Definition: A cutting method in which the planing tool and the workpiece move in the horizontal direction relative to the linear reciprocating motion. Planing is one of the main methods of plane machining. It is the most commonly used processing method of single piece small batch production plane processing. Common planer machine tools include planer, planer and slotting machine.

Five, broaching
Definition: The method of processing the inside and outside of the work piece by using the broaching knife to make axial motion under the action of tension. A multi-tooth broach is used to cut a thin metal layer from the workpiece one by one, so that the surface can achieve a higher precision and a smaller roughness value.

Six, milling

Definition: A cutting method by which the main motion is rotated by the milling cutter and the workpiece or the milling cutter is fed. Milling is one of the main machining methods of a plane. During milling, the main motion is the rotation of the parts along with the milling cutter of the workbench. Commonly used lifting table horizontal milling machine and vertical milling machine. The motion of milling large parts is the feed motion. There are many kinds of milling machines, and the plane is used as a gantry milling machine. Used for mass production, high productivity.

7. Grinding

Definition: The grinding method of the workpiece surface when the grinding tool is rotated at a high linear speed. Usually the use of abrasive tools for processing called grinding machine. The commonly used grinding tools are consolidated abrasive tools (such as grinding wheel, whetstone, etc.) and coated abrasive tools (such as abrasive belt, emery cloth, etc.). Grinding machines can be divided into cylindrical grinding machines, internal grinding machines and surface grinding machines according to different processing purposes.
