How to read milling machine

Milling machine, pronounced "xǐ chuáng". The following is a detailed description of the milling machine:

What is a milling machine?

Milling machine is one of the commonly used machine tools in metal processing. It cuts on the workpiece by rotating the tool, and realizes the machining and modeling of the workpiece surface. Milling machines are widely used in various industries, such as aerospace, automobile manufacturing, mold manufacturing, machinery manufacturing and so on.

Working principle of milling machine

The working principle of milling machine is based on the rotation of cutter and the movement of workpiece. The cutter is fixed on the spindle of the milling machine and driven by the rotation of the spindle. At the same time, the workpiece is fixed on the workbench, and cutting motion is formed between the tool and the workpiece through the movement of the workbench. Milling machine can realize cutting in different directions, such as plane milling, end milling, vertical milling, curved surface milling and so on.

Structure and components of milling machine

1. Spindle box: install the spindle and spindle drive system so that the spindle can rotate.

2. Worktable: used to fix the workpiece and can move in the horizontal and vertical directions.

3. Tool rest: used to fix the tool so that the tool can cut during machining.

4. Feed system: including feed shaft and feed transmission mechanism, which is used to control the movement of the workbench and realize cutting movement.

Classification of milling machines

Milling machines can be classified according to different structures and functions. Common classifications are:

1. According to the number of cutters, it is divided into single-cutter milling machines and multi-cutter milling machines.

2. According to the movement mode of the workbench, it can be divided into vertical milling machine, horizontal milling machine and gantry milling machine.

3. According to the control mode, it can be divided into manual milling machine, numerical control milling machine and automatic milling machine.

4. According to the machining accuracy, it is divided into ordinary milling machines and high-precision milling machines.

Application field of milling machine

Milling machines are widely used in all walks of life. The following are some common application areas:

1, mold manufacturing: used to process the outline and curved surface of the mold.

2. Aerospace: used for processing aircraft parts and engine parts.

3. Automobile manufacturing: used for processing automobile parts, such as engine cylinder block and crankshaft.

4. Mechanical manufacturing: used to process various metal parts, such as gears and bearing seats.

Matters needing attention in milling machine operation

1, check whether the fixture is installed correctly before operation.

2. Wear protective glasses and work gloves when operating to ensure personal safety.

3. Pay attention to the use of cutting fluid to reduce cutting heat and prolong tool life.

4. For large workpieces, attention should be paid to balance and fixation to avoid vibration and deformation.

5, regular cleaning and maintenance of milling machine, to ensure its normal operation and service life.
