A grinding machine is a machine tool that processes various surfaces of a workpiece with an abrasive or abrasive. Generally used for grinding hardened surfaces of parts. Generally, the grinding tool rotates as the main motion, and the movement of the workpiece or the grinding tool is the feed motion. The application is extensive, the machining precision is high, the surface roughness Ra is small, and the grinding machine can be divided into more than ten kinds:
(1) Cylindrical grinding machine: It is a common type of basic type, mainly used for grinding grinding machines with cylindrical and conical outer surfaces.
(2) Internal grinding machine: It is a common type of basic type, mainly used for grinding grinding machines with cylindrical and conical inner surfaces.
(3) Coordinate grinding machine: an internal grinding machine with a precision coordinate positioning device.
(4) Centerless grinding machine: the workpiece is uncentered, generally supported between the guide wheel and the bracket, and the workpiece is rotated by the guide wheel, which is mainly used for grinding the cylindrical surface.
(5) Surface Grinding Machine: A grinding machine mainly used for grinding the plane of a workpiece.
(6) Belt Grinding Machine: A grinding machine that grinds with a fast moving belt.
(7) Honing machine: A grinding machine for honing various surfaces of workpieces.
(8) Grinder: A grinding machine for grinding the inner or outer surface of a workpiece.
(9) Guide grinding machine: It is mainly used to grind the grinding machine surface of the machine tool.
(10) Tool Grinding Machine: Grinding machine for grinding tools.
(11) Multi-purpose grinding machine: a grinding machine for grinding cylindrical, conical inner and outer surfaces or planes, and capable of grinding a variety of workpieces with followers and accessories.
(12) Special grinding machine: special machine tool for grinding certain parts. According to its processing objects, it can be divided into: spline shaft grinding machine, crankshaft grinding machine, cam grinding machine, gear grinding machine, thread grinding machine, curve grinding machine and so on.
Cabinet display lighting are gaining traction among museums and galleries for several reasons, not the least of which is that they are the safest source for light-sensitive artwork. Compared to other sources, Fibre optic display produce far less ultraviolet (UV) radiation
Caring for and preserving collections is among the most mission-critical tasks a history organization is charged with. Creating a physical environment that ensures that those collections are preserved for future generations is often the most cost-effective way to address the collection as a whole. In short, it`s cheaper to make sure the collection doesn`t need to be treated for damage than it is to conduct conservation work after the damage is done.
