So for machining different screw threads having different pitches separates tools are used to produce accurate threads.
The nose of the tool is pointed, flat or rounded according to the shape of the root of the thread. The side clearance of the tool for cutting square thread is of prime importance in order to prevent the tool from interfering or rubbing against the vertical flank of the thread. The cutting edge of the tool is exactly similar to an external thread cutting tool but the front clearance angle is sufficiently increased as in a boring tool. The tool is a forged type orbit type and held on a boring bar.
The point of the tool must be set square with the work. A facing tool removes metal by its side cutting edges. So no top rake in necessary in a facing tool. The figure shows H. The length of the tool is , ,, and mm and the nose radius varies from 0. Grooving tool is similar to a parting-off tool illustrated in the figure. An ordinary lathe turning tool may sever the purpose where a copying attachment is used to reproduce the form of a template. Flat forming tools are made of two types:.
These tools have their cutting edges ground to the shape of the groove, undercut, or thread to be cut. Flat dovetail forming tools have a wider cutting edge corresponding to the shape desired. Dovetail end of the tool is fitted in a special tool holder. These tools are preferred in production work as a very long cutting surface can be used resulting in longer tool life. The centre of the tool is set slightly above the centre line of the work to provide an effective front clearance angle on the tool.
The tool will rub against the work if the centres are of the same height. Regrinding is done by grinding the flat only. A boring tool is similar to a left-hand external turning tool so far its cutting edge is concerned.
The tool may be a bit type inserted in a boring bar or holder, or forged type having a tool shank. The figure shows an H.
A boring bar is made of mild steel with slots or holes cut into it to accommodate the tool bit which is locked by an Allen screw. The amount of projection of the cutting edge of the tool from the centre of the bar determines the finished hole diameter of the work. The bit is generally inserted at right angles to the centre line of the bar for boring a continuous hole passing from one end to the other end.
The bit is set at a single to the axis projecting beyond the end of the bar for boring a blind hole. The counterboring operation can be performed by an ordinary boring tool.
