What machine is used for broaching?
In rotary broaching, the broach is rotated and pressed into the workpiece to cut an axisymmetric shape. A rotary broach is used in a lathe or screw machine. In both processes the cut is performed in one pass of the broach, which makes it very efficient.
What are the advantages of broaching?
Advantages of broaching :
- Very high production rate higher than milling, planing, boring etc.
- High dimensional and form accuracy and surface finish of the product.
- Roughing and finishing in a single stroke of the same cutter.
- Needs only one motion of cutting, so design, construction, operation and control are simpler.
What is interspace broach?
Inter-spaced broaches are used where tow or more matching operations are required and production requirements are high. Some teeth finish the hole while other teeth cut the splines.
What is a keyway broach?
Keyseating broaches are used for producing keyway-shaped holes in a workpiece. They are ground to precision keyway tolerances and designed for AF series machines. Keyway broaches are used for producing keyway-shaped holes in a workpiece. They may be used with shims if the depth cannot be broached in a single pass.
What are different types of broaching machines explain any one type?
There are two principal types of broaching machines: horizontal and vertical. In addition to these standard types, there are special and continuously operating machines. Both horizontal and vertical types of machine have one or more rams depending on production demand.
What are the advantages and limitations of broaching?
Advantages of broaching : Very high production rate higher than milling, planing, boring etc. High dimensional and form accuracy and surface finish of the product. Roughing and finishing in a single stroke of the same cutter. Needs only one motion of cutting, so design, construction, operation and control are simpler.
How are keyways machined?
A notch called a keyway is cut on the inside of the gear along with another notch cut, longways, into the shaft. Then and a piece, usually metal, called a key is inserted into the shaft keyway. The gear can then be fitted onto the shaft and the keyway on the gear will fit over the key, inserted in the shaft.
What is horizontal broaching machine?
Horizontal broaching refers to the type of machine that is used to broach a piece part. The horizontal machine has the power cylinder and the machine body oriented horizontally, with the broach being pulled through or past the piece part.
What is a slotter machine?
Definition of slotting machine : a machine tool with a vertically reciprocating planing tool used for making a mortise or shaping the sides of an aperture.
What is a large type broaching machine?
Large type broaching machine for heavy cutting and high accuracy. Maintenance free with rack and pinion drive. Thermal rigidity is greatly improved and high accuracy is guaranteed. A power-saving, high-efficiency, high-precision mechanical system.
What are the advantages of internal broaching machine?
Internal broaching machine, space saving and made of simple construction. High productivity from keyway to spline cutting. For mass production with multi-station available. High rigidity to withstand severe cutting. High efficiency broaching machine exclusive for surface cutting. High rigidity can maintain high accuracy for a long period.
What are the advantages of Broach inverter?
Minimized tool exchange time by broach inverter. Internal helical gear can be cut with high efficiency. Offers high accuracy cutting which cannot be realized with gear cutting machine. Push-up type of simple construction.
