CNC machined metal parts general post-processing information

Heat treatment

Heat treatment is to heat the machined metal workpiece to a suitable temperature in a certain medium, and after maintaining it at this temperature for a certain period of time, it is cooled in different medium at different speeds, by changing the surface or internal microstructure of the metal material. A process in which structures are used to control their properties. Its purpose is to change the hardness, strength, wear resistance, electrical and magnetic properties of the metal. The overall heat treatment of steel generally has four basic processes: annealing, normalizing, quenching and tempering.

Polishing

Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is the modification of the workpiece surface by polishing tools and abrasive particles or other polishing media.

Sandblasting

Sandblasting is powered by compressed air to form a high-speed jet beam to spray materials (copper ore, quartz sand, emery, iron sand, Hainan sand) to the surface of the workpiece to be treated at high speed. The impact of the sand flow cleans and roughens the surface of the substrate. The process of changing the outer surface or shape of a workpiece.

Brushed

The surface brushed treatment of machined parts is a surface treatment method that forms lines on the surface of the workpiece by grinding the product, which has a decorative effect. According to the different lines after brushed, it can be divided into: straight line brushed, random pattern brushed, corrugated pattern brushed, swirl pattern brushed.

Anodizing

Anodizing is an electrolytic oxidation process in which the surface of aluminum and aluminum alloys is usually transformed into an oxide film, which has protective, decorative and other functional properties, such as surface coloring, improving Corrosion resistance, enhanced wear resistance and hardness, protection of metal surfaces, etc.

Black oxide

The black oxide process, also known as the chemical oxidation process, immerses the processed parts in an oxidizing solution for a certain period of time, so that an oxide film is formed on the surface of the parts. This layer of oxide film can appear black, purple, blue, brown and so on. The appearance of the oxide film has a certain decorative effect, and the oxidation process has a certain anti-corrosion performance.

Coating

Spraying is a coating method that is dispersed into uniform and fine droplets by means of pressure or centrifugal force through a spray gun or disc atomizer and applied to the surface of the object to be coated. The spraying operation has high production efficiency and is suitable for industrial automation production. The application scope is mainly in the fields of hardware, plastics, furniture, military industry, ships and so on. Powder coating is popular in automotive industry.

Rolling process

Rolling processing is a kind of plastic processing method in which a high hardness and smooth roller is rolled into contact with the metal surface, and the surface layer undergoes a small amount of plastic deformation to improve the surface roughness.

Electroplating

Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. So as to prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics.

Electrophoresis

The electrophoresis process is divided into anodic electrophoresis and cathodic electrophoresis. A process in which paint particles are deposited on the surface of a workpiece under the action of an electric field.

Etching

Etching, also known as photochemical etching, refers to the removal of the protective film in the area to be etched after exposure to plate making and development, and contact with chemical solutions during etching to achieve the effect of dissolution and corrosion, forming concave-convex or hollow molding effects.

PVD coating

Physical Vapor Deposition refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to evaporate the target and ionize both the evaporated material and the gas, and use the acceleration of the electric field to make the evaporated material and its gas. The reaction products are deposited on the workpiece.
PVD technology is widely used in aerospace, electronics, optics, machinery, construction, light industry, metallurgy, materials and other fields. A film with properties such as conductivity.

Laser engraving

Laser engraving is a process of surface treatment using optical principles. The high-intensity focused laser beam emitted by the laser is at the focal point, the material is oxidized, and it is processed to show the desired etched graphics and text.

PRECISION CNC MACHINING

CNC MILLING

CNC milling is a subtractive manufacturing process that produces custom-designed parts or components by progressively removing material from the workpiece using 3-axis milling and 5-axis indexed milling machines by rotating multi-point cutting tools and computerized controls. These systems usually have three linear degrees of freedom. They can move freely around the X, Y, and Z axes while the workpiece remains stationary, to cut solid plastic and metal blocks into final parts. For complex components, will apply 5-axis moving. This limited dimensional operation reduces the speed of operations, making milling more suitable for prototype making and low-volume production runs.

CNC TURNING

CNC turning is a manufacturing process that involves holding bars of material in a chuck and rotating them while feeding a tool to the piece to remove material until the desired shape is achieved. The CNC turned part`s shape is cylindrical features from metal rod stock by live tooling that combines both lathe and mill capabilities. CNC turning is manufacturing through material removal, also known as subtraction machining. The speed of CNC turning operations makes it an ideal process for high-volume production runs with short lead times.
