Machining (machining): core technologies and applications for modern manufacturing

Machining (työstö): Core technologies and applications for modern manufacturing
Machining (referred to as machining) is a manufacturing process of cutting, forming and other processing of workpieces through mechanical equipment to obtain the desired shape, size and surface quality. As the basic process of manufacturing, machining technology directly affects product quality, performance and productivity.

Main classifications and methods of machining
Conventional Cutting
Turning: workpiece rotation, tool movement, suitable for shafts, disc parts

Milling: the tool rotates and the workpiece moves, suitable for flat surfaces and grooves.

Drilling: specialised in hole processing, including drilling, reaming, reaming, etc.

Grinding: for high-precision surface machining up to IT6 accuracy

Modern speciality processing
EDM: for complex profiles in high hardness materials.

Laser processing: high precision, non-contact characteristics

Ultrasonic machining: precision machining for brittle materials

Water jet cutting: no heat affected zone, environmentally friendly and efficient

Application of CNC technology in machining
The popularity of numerical control (CNC) machine tools has brought machining into the digital age. Through computer programming and control, the machining process is automated and intelligent:

Machining accuracy up to ±0.005mm

Increase productivity by 3-5 times

One person can operate multiple machines

Significant improvement in product quality stability

Machining key technical parameters
Three elements of cutting
Cutting speed: Selected according to material hardness

Feed: affects surface roughness

Depth of cut: determines machining efficiency
