Cutting mill - Wikipedia

Cutter mills are mills commonly used in laboratories for the preliminary size reduction of soft, medium-hard, fibrous and tough materials. A rotor inside the mill revolves at high speed. The rotor is equipped with special cutting plates which comminute the sample material. Different rotor geometries make mills adaptable to different material properties (medium-hard, soft, fibrous or elastic ...

Milling (machining) - Wikipedia

29/01/2013· Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction 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.

Sawmill | The Canadian Encyclopedia

Far more significant were the fewer, larger mills cutting logs for export. Equipped with gang saws and ancillary machinery, they produced better lumber faster. After 1840 new technologies increased their size and efficiency. Circular saws were used for edging and trimming. The continuous-cutting band saw largely replaced the reciprocating gang after 1890. Rollers and log chains moved material ...

Cutting Mills are ideal for comminution of soft to medium-hard, brittle, fibrous, tough or temperature-sensitive materials as well as plastics and for preparation of heterogeneous mixtures. The samples are comminuted by cutting and shearing forces, and the selected sieve cassette determines the final fineness. Various knife geometries and replaceable blades ensure maximum flexibility and ...

Hand tool - Saw - Encyclopedia Britannica

Hand tool - Hand tool - Saw: The chipped flint knife, with its irregular edge, was not a saw in the proper sense, for though it could sever wood fibres and gash bone or horn, it could not remove small pieces of material in the manner of a saw. Furthermore, the necessarily broad V-shaped profile of the flint saw severely limited its penetration into the workpiece; the nature of its cut was ...

Sweatshops | Encyclopedia.com

One of the earliest examples of a sweatshop was in the crude textile mills of Ecuador. Spanish conquerors put the native population to work in sweatshop conditions in the manufacture of cloth, rough garments, and assorted textile goods. The use of the term is more recently traced to working conditions in England's emerging manufacturing industries, where women and children sweated in jobs ...

Article about millings by The Free Dictionary - Encyclopedia

The cutting speed is equal to the rim speed of the tooth points farthest from the cutter axis. Three types of feed are distinguished in milling: feed per minute S (in mm/min); feed per revolution of the cutter S r (in mm per revolution); and feed per tooth of the cutter S t (in mm per tooth), which is the relative movement of the cutter and work-piece as the cutter turns one angular step ε ...

The major cutting center of Germany is Idar-Oberstein, and they held on to ancient stone cutting practices for longer than anyone else in Europe. Idar-Oberstein started cutting stones on waterwheel-powered cutting mills towards the end of the 1200s. The work was hard and slow and back breaking. Before the existence of a flat spinning wheel impregnated with diamond powder, there was sandstone ...

Paper mill - Wikipedia

Paper mills can be fully integrated mills or nonintegrated mills. Integrated mills consist of a pulp mill and a paper mill on the same site. Such mills receive logs or wood chips and produce paper. The modern paper mill uses large amounts of energy, water, and wood pulp in an efficient and complex series of processes, and control technology to produce a sheet of paper that can be used in ...

Anatomy of a CNC Router

The spindle is the shaft that rotates very fast. It is attached to a big motor on one side and your cutting bit (or a holder that holds your bit) on the other side. For CNC routers, a spindle speed of 10,000-20,000 RPM is standard. For CNC mills, the spindle is generally much slower at 1,000-10,000 RPM, but with significantly more torque.
