What are the machining methods

Machining: in the process of machining, it is often necessary to carry out cold and heat treatment. According to the different temperature of the part itself during operation, machining can be divided into cold and hot. Cold working is processed at room temperature and is usually used for cutting operations; Cold working is usually used for processing at room temperature; Cold working usually refers to heat treatment, in which the temperature is lower or higher than the room temperature, and the working components are physically changed through temperature changes to complete the assembly.

In addition, machining also needs to pay attention to the problem of moving parts: the moving parts of inertial collision must take reliable cushioning measures to prevent injury caused by inertia. Any moving parts that are easy to cause injury shall be closed or sealed, machined or other protective measures shall be taken to avoid the contact of operators. The machining equipment shall be provided with reliable limit devices as required. In order to avoid crushing and injury, the distance between linear moving parts or linear moving parts and stationary parts must meet the regulations.

Machining - pre bending

When rolling, the tablet has a length at both ends because it cannot be connected to the upper roll and will not bend. It is called the residual straight edge. Technically, the smaller force arm that the tablet begins to bend is called the theoretical residual straight edge. Its size is related to the equipment structure and bending form, that is, "symmetrical bending, asymmetric bending". The purpose of alignment is to make the generatrix of the workpiece parallel to the roll axis to prevent skew. Round roll is the main process of product forming. It is divided into one feed and multiple feed. Rolled thick plates are usually fed multiple times.

Machining - plane machining

The main surfaces of boxes, plates and plate-shaped parts are flat. In addition to surface roughness, plane technical requirements often consider its shape and position accuracy. The plane can be processed by automobile, milling, planing and grinding. The end plane of shaft sleeve and disc is usually machined simultaneously with the outer circle or inner hole after one clamping on the lathe. The cutting is applicable to the long plane of small batch single piece production or processing. Milling has high productivity, and milling cutting is used in mass production.

Milling (vertical milling and horizontal milling): milling is the processing of cutting metal with a rotary knife. It is mainly used to process grooves and linear surfaces. It can also be connected with two or three axes to process arcs.

Cast hole: cast hole is a processing method, which can expand the drilled or cast hole on the workpiece or be used for further processing. It is mainly used to process workpieces with large shape, large diameter and high precision.

Planing: the main function of planing is to treat the straight surface. Generally, the surface roughness is not high.

Insert cutting: insert cutting is actually a vertical planer. Its knife moves up and down, which is very suitable for non complete arc machining. It is mainly used to cut some types of gears;

Grinding: "surface grinding, cylindrical grinding, inner hole grinding, tool grinding, etc." grinding and cutting is the processing method of cutting metal with grinding and cutting wheel. The processed workpiece has accurate size and smooth surface. It is mainly used for finishing the heat-treated workpiece to achieve accurate size.

Drilling: drilling is to drill holes on solid metal workpieces with rotary drill bits; Drilling is the process of drilling on solid metal workpiece with rotary drill bit; Drilling is the use of rotary drills to drill and drill on solid metal workpieces.
