a machine vise made from ferromagnetic steel or cast iron placed on the magnetic chuck can be used to hold non-ferromagnetic workpieces if only a magnetic chuck is available. factors to consider in surface grinding are the material of the grinding wheel and the material of the piece being worked on.
a bench grinder is a benchtop type of grinding machine used to drive abrasive wheels. a pedestal grinder is a similar or larger version of grinder that is mounted on a pedestal, which may be bolted to the floor or may sit on rubber feet. these types of grinders are commonly used to hand grind various cutting tools and perform other rough grinding.
a backplate with threads may screw onto a threaded spindle nose for lathe work or onto an adapter plate with the same nose, to be mounted on the table of milling machines or surface grinding machines. this 'threaded spindle nose' type of mounting was the typical method in the 19th century through 1930s.
the origins of the cylindrical grinder, as with all other modern machine tools, stem from the experimentation and invention of john wilkinson and later henry maudslay who built the first horizontal boring machine and the first engine lathe, respectively.
the provision and use of work equipment regulations, commonly abbreviated to puwer 1998 or simply puwer, is a statutory instrument of the united kingdom. it regulates the standards of safety for equipment used in work environments. its obligations apply to both employers and employees, as well as those who provide equipment for others to use at work.
a toolroom is a room where tools are stored or, in a factory, a space where tools are made and repaired for use throughout the rest of the factory. in engineering and manufacturing, toolroom activity is everything related to tool-and-die facilities in contrast to production line activity.. originally a toolroom was literally in one room, but like emergency room, the term has been figuratively .
a collet / ˈ k ɒ l ɪ t / is a subtype of chuck that forms a collar around an object to be held and exerts a strong clamping force on the object when it is tightened, usually by means of a tapered outer collar. it may be used to hold a workpiece or a tool. an external collet is a sleeve with a normally cylindrical inner surface and a .
grinding is an abrasive machining process that uses a grinding wheel as the cutting tool. a wide variety of machines are used for grinding: hand-cranked knife-sharpening stones handheld power tools such as angle grinders and die grinders various kinds of expensive industrial machine tools called grinding machines bench grinders grinding practice is a large and diverse area of manufacturing and toolmaking. it can produce very fine finishes and very accurate dimensions; yet in mass production cont
a tool and cutter grinder is used to sharpen milling cutters and tool bits along with a host of other cutting tools. it is an extremely versatile machine used to perform a variety of grinding operations: surface, cylindrical, or complex shapes.
a rotary transfer machine is a machine tool, typically for metal working by machining, comprising a large indexing table with machining stations surrounding the table. such rotary transfer machines are used for producing a large lot of parts in fairly short cycle times. operation. in rotary transfer machines, the workpieces are located and clamped in pallet type fixtures that are indexed in a .
a burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process.. it is usually an unwanted piece of material and is removed with a deburring tool in a process called 'deburring'. burrs are most commonly created by machining operations, such as grinding, drilling, milling, engraving or turning.it may be present in the form of a fine wire on .
a grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding, it is a type of machining using an abrasive wheel as the cutting tool. each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation. grinding is used to finish workpieces that must show high surface quality and high accuracy of shape and dimension. as the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications it ten
a machinist is a tradesperson who machines using hand tools and machine tools to create or modify a part that is made of metal, plastics, or wood, although plastics or wood machining is rarely manufactured by machinists as those materials require lesser skill and almost all the work performed by a machinist is done on metal. a machinist is to metal what a carpenter or cabinet maker is to wood.
a drill press also known as a pedestal drill, pillar drill, or bench drill is a style of drill that may be mounted on a stand or bolted to the floor or workbench. portable models are made, some including a magnetic base. major components include a base, column or pillar , adjustable table, spindle, chuck, and drill head, usually driven by an .
