A light chip load at high feed and RPM is often referred to as High Speed Machining (HSM), and can provide quick machining times with high quality results. [18] The result of these lighter passes is a highly accurate part, with a uniformly high surface finish. In addition to modifying speeds and feeds, machinists will often have finishing ...
The high-speed angle grinder was invented in 1954 [6] by German company Ackermann + Schmitt (FLEX-Elektrowerkzeuge GmbH) in Steinheim an der Murr. [7] As a result, in German, Dutch, Slovak, Czech, Polish, Croatian, Romanian, Hungarian, Bulgarian and Latvian, an angle grinder is colloquially called a "flex", and in Italy and in Spanish-speaking ...
Ultra-high speed grinding (UHSG) can run at speeds higher than 40,000 fpm (200 m/s), taking 41 s to remove 1 in 3 (16 cm 3) of material, but is still in the research-and-development (R&D) stage. It also requires high spindle power and high spindle speeds.
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is superior to high-carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel.
Machining is a form of subtractive manufacturing, [1] which utilizes machine tools, in contrast to additive manufacturing (e.g. 3D printing), which uses controlled addition of material. Machining is a major process of the manufacture of many metal products, but it can also be used on other materials such as wood, plastic, ceramic, and ...
The company developed the first drop-tank wire EDM in 1994, [6] and HQSF (High-Quality Surface Finish) technology with patented uSc additive in 1996, [6] increasing the ability to finish parts without hand polishing when using a ram EDM. In 2003, Makino developed the first conventional horizontal wire EDM that automatically threads and machines ...
Production of automatically controlled drilling machines began in 1972, and vertical machining centers from 1974. The company began exporting to the United States from 1975. In 1981, Matsuura Machinery began production of high-speed machining centers and twin-spindle vertical machining centers, and horizontal machining centers from 1983.
