Millingmachine tools name

(1) There is the overarm which supports the arbor with its cutting tool, the milling cutter; (2) there is the table which brings the work up and feeds it into the spinning cutters; (3) there is the knee, which travels up and down and on which the table rests; and (4) the column with its ways on which the knee travels up and down.
7.) Spindle: Inside the column is a mechanism which rotates a spindle located near the top of the mill. Into this spindle are inserted accessories, like the arbor, a shaft for support of the cutters. The spindle supplies the rotational power to the arbor and the cutters.
8.) Overarm: Above the spindle, an overarm projects out in a horizontal plane above the table and the work. Its job is to hold one or more arbor supports.

1.) Base: The entire machine rests on a heavy metal base. This base has a dish-shaped top which acts as a reservoir for cutting fluid.
6.) Table: The table rests on the saddle’s guideways. The table is very flat and is the part to which the work is securely fastened. There are T-slots that run the entire length of the table. T-bolts can be fitted into these T-slots to help secure the work.

(4) swivel movement: As we have seen, the table can be turned up to 45° away from the longitudinal axis of the table in the horizontal plane by turning the table swivel housing.

3.) Knee: The knee contains the mechanism (moving parts) which control the vertical movements of the knee; there is an automatic mechanism which allows for an automatic feed at a given rate; there is another mechanism which allows the machinist to move the knee up and down manually by the use of a hand crank.
2.) Column and Ways: The column is attached to the base and has ways that are very precisely made to guide the up and down motions of the knee.
HSS drill bits, an acronym for high speed steel drill bits are extremely hardwearing and particularly well designed for drilling into metal surfaces, as they are much more resistant to the heat generated from the fast speed operation. The front edges cut the material, whilst the spirals remove debris from the hole. Light pressure should be applied when using smaller bits to prevent them from breaking. HSS bits can be also be used for drilling wood and plastic materials.
13 different types ofmillingcutters
(1) longitudinal movement (or table feed): The table can be moved in the horizontal plane in the direction of either end of the table. (Side to side)
5.) Table Swivel Housing: Some horizontal mills have an added feature, a part located between the saddle and the table called the table swivel housing. This allows the table to be swiveled (turned) at 45° angles to either side, in the table1s horizontal plane. If a horizontal mill has a table swivel housing, it is called a universal horizontal milling machine, because it is capable of more jobs.

9.) Arbor supports: One or more arbor supports can be attached and clamped in place anywhere along the overarm. As their name indicates, their purpose is to hold, support, and align the arbor and whatever cutters are on it.
(3) cross feed: As we have seen, the table can be moved in, toward the column, or out, away from the column, by movements, in or out, of the saddle.
Because it uses the knee and the column as the means by which work is fed into the cutter, the horizontal mill is called a “knee-and-column” milling machine.

4.) Saddle: The saddle 1s situated on top of the knee and beneath the table; the saddle has controls which allow for the table to be moved in toward the column, or out, away from the column. This motion is called cross feed; it can be done using either manual or automatic controls (which we will soon study).
