Starrag
Starrag AG, headquartered in Rorschacherberg, Switzerland, is a manufacturer of precision machine tools. It operates as a subsidiary of the StarragTornos Group. History The history of Starrag dates back to 1897 when Henry Levy founded a workshop in Rorschacherberg to manufacture threading machines for the textile industry. These threading machines eliminated the need for manual threading of embroidery machines, a task that had predominantly been performed by child labour. By 1910, the workshop had produced 3000 threading machines and other machines for the textile industry. After the outbreak of World War I in 1914 caused a textile crisis in Eastern Switzerland, the company shifted its focus to the production of turret and parallel lathes in 1917. From 1920 onwards, the company began manufacturing milling machines, and in 1921, it was renamed ''Starrfräsmaschinen AG Henri Levy'', later becoming ''Starrfräsmaschinen AG'' in 1925. By this time, the company had over 300 employe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Machine Tool Builders
A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage. Modern machines are complex systems that consist of structural elements, mechanisms and control compone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blisk
A blisk (portmanteau of bladed disk) is a turbomachine component comprising both rotor disk and blades as a single part instead of a disk assembled with individual removable blades. Blisks generally have better aerodynamics than conventional rotors with single blades and are lighter. They may be additively manufactured, integrally cast, machined from a solid piece of material, or made by welding individual blades to a rotor disk. The term is used mainly in aerospace engine design. ''Blisks'' may also be known as integrally bladed rotors (IBR). History Blisk manufacturing has been used since the mid-1980s. It was first used by Sermatech-Lehr (now known as GKN Aerospace) in 1985 for the compressors of the T700 helicopter engine. Since then, its use has continued to increase in major applications for both compressors and fan blade rotors. Examples include the Rocketdyne RS-68 rocket engine and the General Electric F110 turbofan. The F-35B variant of the Joint Strike Fighter us ...

Impeller
An impeller, or impellor, is a driven rotor used to increase the pressure and flow of a fluid. It is the opposite of a turbine, which extracts energy from, and reduces the pressure of, a flowing fluid. Strictly speaking, propellers are a sub-class of impellers where the flow both enters and leaves axially, but in many contexts the term "impeller" is reserved for ''non''-propeller rotors where the flow enters axially and leaves radially, especially when creating suction in a pump or compressor. In pumps An impeller is a rotating component of a centrifugal pump that accelerates fluid outward from the center of rotation, thus transferring energy from the motor that drives the pump to the fluid being pumped. The acceleration generates output pressure when the outward movement of the fluid is confined by the pump casing. An impeller is usually a short cylinder with an open inlet (called an eye) to accept incoming fluid, vanes to push the fluid radially, and a splined, keyed, or ...

Turbine Blade
A turbine blade is a radial aerofoil mounted in the rim of a turbine disc and which produces a tangential force which rotates a turbine rotor. Each turbine disc has many blades. As such they are used in gas turbine engines and steam turbines. The blades are responsible for extracting energy from the high temperature, high pressure gas produced by the combustor. The turbine blades are often the limiting component of gas turbines. To survive in this difficult environment, turbine blades often use exotic materials like superalloys and many different methods of cooling that can be categorized as internal and external cooling, and thermal barrier coatings. Blade Fatigue (material) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Milling (machining)
Milling is the process of machining using rotary Milling cutter, cutters to remove material by advancing a cutter into a workpiece. This may be done by varying directions on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances. Milling can be done with a wide range of machine tools. The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into ''machining centers'': milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures. Milling centers are generally classified as vertical machining centers (VMCs) or horizontal machining centers (HMCs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
