A micrometer is a measuring tool used to precisely measure lengths on small scales. In principle, spiral micrometers can be divided into mechanical micrometers and electronic micrometers. The mechanical micrometer is made according to the principle of spiral magnification.
Turbine blades are an important component of the turbine section in a gas turbine engine. The high-speed rotating blades are responsible for drawing high-temperature and high-pressure air into the burner to maintain the engine's work.
CBN turning tools are tightly sintered from boron nitride and tungsten carbide bases. The hardness of boron nitride is next to PCD. It has excellent chemical stability and will not produce affinity with iron, cobalt, and nickel-based metals. Therefore, it is especially suitable for work hardening steel, with a hardness above HRC45. Chilled cast iron and heat-resistant steel (Inconel) are also suitable.
A wrench is a tool used to turn bolts, nuts, and other objects that are difficult to turn by hand. A wrench is a tool that uses the principle of leverage as its actuation mechanism.
Although the figure of the fastener is inconspicuous, it is a rare but important existence in daily life. Fasteners are used in aircraft carriers, airplanes, high-rise buildings, as small as watches, mobile phones, glasses, etc.
Taiwan's hand tool industry is well-known in the world and once created the title of the screw kingdom. At present, the hand tool industry is faced with the challenges of the international situation, lack of manpower, exchange rate and other factors, coupled with the rise of emerging countries and the same industry in mainland China, what should they do to deal with the chaotic situation?
Valve is an important adjustment device in the fluid transportation system, which can basically control the on-off, flow and flow direction of the fluid. There are many types and specifications of valves, and the valves used for different work requirements are also different. The working principles, advantages and disadvantages of 5 common types of valves are described below.
The commonly used control items on industrial pipelines and equipment mainly refer to some commonly used valves, which are used to control the flow of the medium in the pipeline.
Rapid molding technology is a fast, convenient, and practical mold manufacturing technology. It is especially suitable for the development and trial production of new products, process verification, and functional verification, as well as multi-variety and small batch production.
A pair of molds is composed of an upper mold and a lower mold. The male die is a concave die, also known as the upper die. The design of the male mold is very important, and the structural characteristics of the female mold itself change with the structure of the product and the processing method of the mold, which is flexible.
An injection mold is a tool for producing plastic products; it is also a tool for imparting complete structure and precise dimensions to plastic products. Because the production method is to inject the plastic melted at high temperature into the mold through high pressure and mechanical drive.
A method of transmitting rotational force between two separated shafts using pulleys and belts. The rotation speed ratio is inversely proportional to the diameter of the two pulleys, and it can slide when the load is excessive to prevent mechanical damage.
Hand tools can be divided into wrenches, pliers, screwdrivers, etc. according to their uses, which are used to assist the assembly, maintenance, or tightening and loosening needs of machines or objects.
The advanced processing device and the high-efficiency CNC tool can give full play to its effect and obtain good economic benefits. Because the tool is subjected to high pressure, high temperature, friction, shock and vibration when cutting. Material is an important factor affecting the cutting ability of a tool, and also has a considerable impact on processing efficiency, processing quality, processing cost and tool durability.
Nowadays, products have many functions and high complexity, so the requirements for the quality and precision of molds are becoming more and more stringent. Only through a complete evaluation and testing in the early mold development process can we produce mold products that customers are satisfied with.
To exert the cutting ability of the tool, the tool material needs to have significant progress and improvement. Various tool materials currently used have their characteristics to meet various processing requirements.
Hardware can be seen everywhere and used everywhere in our lives, especially on some large and small machines, many parts of which are made of hardware. It can be used separately or as an auxiliary, such as hardware tools, hardware parts, daily hardware, construction hardware and security supplies, etc. Let's learn what hardware includes and the classification of hardware accessories.
Quick Die Change (SMED), or 10-minute die change, is a set of useful techniques for dealing with multiple batches of small quantities and improving the rapid response capability of the production system and is a type of lean production method. The point is to convert internal jobs to external job conversions as much as possible.
