Milling Machine • Milling Machine • A device that rotates a circular tool that has a number of cutting edges symmetrically arranged about its axis. • The workpiece is commonly held in a vise or similar device clamped to a table that can move in three perpendicular directions. 5. Labelled Diagram. 6.
Indexing devices. The simplest way of indexing is by means of collet blocks. The collet block is a square or hexagonal block with a hole in it designed to take a collet. The workpiece is held in a collet. The collet is held in a collet block. The collet block is held in a vice. It can be held horizontally or vertically.
RACK MILLING ATTACHMENT. Its mounted between the face of column and outer. support on a plain or universal milling machine. It consists a fixed housing and a spindle. A special rack indexing attachment used to move. the work longitudinally with accurate spacing of. teeth. 9. CIRCULAR TABLE ATTACHMENT.
Simple Indexing. Simple indexing on a milling machine is passed out through the use also a plain indexing head or universal dividing head. This process of indexing, especially when using the indexing head in a …
Milling is a process of producing flat and complex shapes with the use of. multi-tooth cutting tool, which is called a milling cutter and the cutting edges. are called teeth. The axis of rotation of the cutting tool is perpendicular to the direction of. feed, either parallel or perpendicular to the machined surface.
5. As the workpiece moves against the cutting edges of milling cutter, metal is removed in form chips Machined surface is formed in one or more passes of the work. The work to be machined is held in a vice, a rotary table, a three jaw chuck, an index head, in a special fixture or bolted to machine table. In many applications, due to its higher …
