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.
High speed steel is commonly used when a special tool shape is needed, not usually used for high production processes. Ceramics inserts are typically used in high speed machining with high production.
CFG has grinding depth up to 6 mm (0.236 inches) and workpiece speed is low. Surfaces with a softer-grade resin bond are used to keep workpiece temperature low and an improved surface finish up to 1.6 μm Rmax. CFG can take 117 s to remove 1 in 3 (16 cm 3) of material. Precision grinding would take more than 200 s to do the same.
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 ...
Both are operated by Stahlberg Roensch. The larger machine, RC01, has four grinding units, each with 24 grinding stones. A smaller machine using one grinding unit with 16 grinding stones is also in use. RC01 is used on main line and high speed tracks of DB Netz AG, while the smaller version is deployed mostly on commuter and metro rail networks.
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 ...
Milling is the process of machining using rotary cutters to remove material [1] by advancing a cutter into a workpiece. This may be done by varying directions [2] on one or several axes, cutter head speed, and pressure. [3]
Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting. This type of machining was originally performed mechanically on large complex machines.
