CNC Machining development background

Numerical control technology originated from the needs of the aviation industry, in the late 1940s, an American helicopter company proposed. The initial idea of CNC machine tools, in 1952, the Massachusetts Institute of Technology developed a three-dimensional CNC milling machine. This type of CNC milling machine has been used for machining aircraft parts in the mid-1950s. In the 1960s, numerical control system and programming work is increasingly mature and perfect, numerical control machine tools have been used in various industrial sectors, but the aerospace industry is always the largest user of numerical control machine tools. Some large aviation factories are equipped with hundreds of CNC machine tools, mainly cutting machine tools. The parts processed by NUMERICAL control include integral panels, girders, skins, compartments, propellers, aero-engine casing, shafts, disks, blade mold cavities and special cavity surfaces of liquid rocket engine combustion chambers, etc. At the beginning of the development of CNC machine tools, CNC machine tools with continuous trajectory are mainly controlled by continuous trajectory. Continuous trajectory control, also known as contour control, requires the tool to move according to the specified trajectory relative to the parts. After the development of point control CNC machine tools. Point-position control refers to the movement of the tool from one point to another, so long as it reaches the target precisely in the end, regardless of the movement path.

Classification Of Aluminum Profiles

How are the common aluminum profiles manufactured? Let's discuss this issue together: Industrial aluminum profiles refer to aluminum substances using different cross-sectional shapes got following hot-melting and extrusion utilizing aluminum sticks. At the same time, industrial aluminum profiles possess many different classification methods based on the program and metal composition. Let's offer you a brief introduction. According to different alloy compositions, aluminum profiles are divided into: 1. Anodized aluminum profiles. 2. Electrophoretic-coated aluminum profiles. 3. Powder-coated aluminum profiles. 4. wood grain transfer type aluminum profiles. 5. planed aluminum profiles. Aluminum CNC Machining can be offered for you from us.

How To Detect Hardware Processing Components？

If you have any ideas about CNC Machining Prototyping, welcome to contact us and discuss them. Usually, we frequently need to use the hardware processing components, we know how to find it? What I want to say now is about the review of hardware processing components. Generally, when using the hardness evaluation of metal stamping components, the majority of them utilize a Rockwell hardness tester. Little, complex-shaped stampings could possibly be utilized to test small planes that can not be analyzed on ordinary benchtop Rockwell hardness testers. The materials processed by stamping parts are primarily hot-rolled or cold-rolled metallic strip materials, such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloy sheet aluminum, and aluminum alloy sheets. Wait. The PHP collection of portable surface Rockwell hardness testers is ideal for testing the hardness of those stamped parts. Alloy stampings are the most frequently used parts in steel processing and gear building. Stamping processing is a processing system in which a metal strip is broken or formed by a mold. Its application range is very wide. The most important purpose of the hardness testing of alloy processing parts would be to ascertain whether the degree of annealing of these bought metal sheets is suitable for the subsequent stamping parts processing. Various types of stamping parts processing processes demand sheets of different hardness levels. After the material depth is higher than 13 mm, the Barcol hardness tester can be used. The pure aluminum plate or perhaps the exact low hardness aluminum alloy plate must be a Barcol hardness tester. In the stamping business, stamping is occasionally called sheet forming, but with a small difference. The term" sheet forming" refers to a forming method where plastic functioning is done using a sheet material, a thin-walled tubing, a thin profile or similar material, and is generally known as sheet forming. In instances like this, deformation in the management of this thick plate is generally not considered. We can offer you with CNC Metal Cutting Prototype based on your requirements.

What Metals are Non Ferrous? (A Complete Guide)

Non-ferrous metals are alloys or metals that do not contain any appreciable amounts of iron. All pure metals are non-ferrous elements, except for iron (Fe), which is also called ferrite from the Latin ‘Ferrum,’ meaning “iron.” Non-ferrous metals tend to be more expensive than ferrous metals but are used for their desirable properties, including lightweight (aluminium), high conductivity (copper), non-magnetic properties or resistance to corrosion (zinc). Some non-ferrous materials are used in the iron and steel industries, such as bauxite, which is used for flux in blast furnaces. Other non-ferrous metals, including chromite, pyrolusite and wolframite, are used to make ferrous alloys. However, many non-ferrous metals have low melting points, making them less suitable for applications at high temperatures. There are a large number of non-ferrous materials, covering every metal and alloy that does not contain iron. Non-ferrous metals include aluminium, copper, lead, nickel, tin, titanium and zinc, as well as copper alloys like brass and bronze. Other rare or precious non-ferrous metals include gold, silver and platinum, cobalt, mercury, tungsten, beryllium, bismuth, cerium, cadmium, niobium, indium, gallium, germanium, lithium, selenium, tantalum, tellurium, vanadium, and zirconium. Non-ferrous metals are usually obtained from minerals like carbonates, silicates and sulphides before being refined through electrolysis. The difference between ferrous and non-ferrous metals is that ferrous metals contain iron. Ferrous metals, such as cast irons or carbon steel, have a high carbon content, which generally makes them vulnerable to rust when exposed to moisture. However, this is not the case for wrought iron, which resists rust due to its purity, and stainless steel, which is protected from corrosion by the presence of chromium.

What is Cold Welding? (Advantages, Disadvantages and Applications)

Cold welding, or contact welding, is a solid-state welding process that requires little or no heat or fusion to join two or more metals together. Instead, the energy used for creating a weld comes in the form of pressure. During the cold welding process, unlike with fusion welding processes, no liquid or molten phase is present in the joint as can be seen in other techniques including arc welding, friction welding or laser welding. Also known as cold pressure welding, this process to join metals without heat was first recognized in the 1940s, although the history of cold welding goes back much further. Widely used for joining wires as well as for joining two metals together in space, this process had a range of applications across the industry.

What is Surface Preparation? (An In-Depth Guide)

Surface preparation refers to the various methods that can be used to treat the surface of material prior to coating application, the use of adhesives and other procedures. Surface preparation is essential for treating steel and other substrates before they are painted, coated or lined. Surface preparation can be done either chemically or mechanically to clear the surface of pre-existing coatings, residue, surface imperfections, organic matter, oxidation and other contaminants. Various surface preparation techniques are used to prepare substrate materials such as aluminum, concrete, plastic, steel and other alloys and wood. While there are different methods of surface preparation for different materials and applications, they tend to follow some set stages.

What are Wind Turbine Inspection Robots? Why Use Them?

Wind turbine inspection robots are robotic devices that are used by onshore and offshore wind turbine operators for the inspection and repair of their assets, most notably on the wind turbine blades themselves. These robotics systems safely and cost-effectively check for blade damage using a variety of blade inspection techniques and technologies, including high-definition cameras for visual inspections and ultrasonic sensors to detect defects occurring below the surface. While these robots can be deployed with a range of technological capabilities, the cost and safety aspects are also significant drivers for the adoption of wind turbine inspection and repair robots by the wind power industry. Wind turbines are often located in remote regions and exposed to extreme environments, especially when located offshore. Downtimes and repairs caused by the failure of both onshore and offshore renewable energy assets are costly and the safety implications of a failure are also considerable. Subjected to hail, rain, humidity, high winds, lightning strikes and millions of load cycles during their lifetime, wind turbine blades often need to be inspected on location. However, manual inspection of a wind turbine blade is dangerous for inspectors using rope or aerial lift access, requires suitable conditions, and is expensive for operators. Inspecting a vertically positioned blade in situ has also posed challenges for the designers of inspection robots, leading to a range of designs from those that use a combination of suction and tank tracks to traverse the surface of a blade, to suction-cup-legged inspect and repair robots.

What is Ultrasonic Welding and How Does it Work?

Ultrasonic welding is a solid-state joining process that uses high-frequency ultrasonic acoustic vibrations, applied locally to workpieces that are held together under pressure. Used for both plastics and metal welding, this technique is able to join dissimilar materials. When applied to metals the temperature stays below the melting point of the materials, which means the properties of the metals are not changed as can be the case with higher-temperature joining methods. Ultrasonic welding removes the need for connecting bolts, nails, adhesives, or soldering materials, making it popular for a range of applications from automotive and aerospace to medical and computing. Early ultrasonic welding was only able to join rigid plastics and it was first applied to the toy industry. However, the first car to be made entirely from plastic was assembled with ultrasonic plastic welding in 1969. The automotive industry dropped the idea of an all-plastic car, but kept using ultrasonic welding as the technology was also taken up by other industries.
