Chamfering is an essential tool to cut off sharp edges after threading operation. Counterboring Tool. Most of these tools are also available in carbide-tipped or tungsten -tipped versions, exllained with the plain steel type. According to the method of applying feed. By the way, if metal lathe cutting tools explained are having any problems setting up the cutting tool this article might help you!

The main function of a rough turning tool is to remove the maximum amount of metal in minimum time that the tool, work, and the machine will permit. The cutting angle is so ground that it can withstand maximum cutting pressure. Turning tool is used to remove the very small amount of metal.

A tool angle is so ground that it can produce a very smooth and accurate surface. Straight turning tools are also used as a chamfering tool when the cutting edges are set at an angle of the chamfer.

Where a large number of chamfer works are to be performed a special chamfering tool with its side cutting edge angle ground to the angle of the chamfer is used. A square shoulder is turned by a knife-edge turning tool or facing tool. A bevelled shoulder may be turned by a straight turning tool having a side cutting edge angle and zero nose radius.

A filleted shoulder is turned by a straight turning tool with a nose radius corresponding to the fillet radius of the work. Metric, B. Its cutting edges sharpened to the shape and size of the thread to be cut. The shape of the tool is determined by the included angle at the nose of the tool which should correspond to the angle of the thread.

W threads. The size or cross-section of the cutting edges of the tool depends upon the pitch of the thread. Below figure illustrates an H. 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 Wood Lathe Cutting Tools 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. The tool cutting edge is so ground that it can leave a shoulder after turning. A counterbore having multiple cutting edges is commonly used. Undercutting or grooving tool has a point and form of the cutting edge exactly similar to the form of the required groove. Clearance angle is given at all the sides of the tool.

For the recessing groove cutting edge, the longitudinal feed is employed. The front clearance Wood Lathe Cutting Tools Jp angle depends upon the bore of the work. A parting off tool is normally forged and used as bits for cemented carbide tipped tools.

Parting off tool is made as narrow as possible to remove the minimum of metal. The width of the cutting edge range from 3 to 12 mm only. The length of the cutting tool which inserts into the work should be slightly longer than the radius of the bar stock being machined. As the tool penetrates deep into the work, clearance Harbor Freight Metal Lathe Tools is provided all around the tool cutting edge to prevent it from rubbing against the work surface.

As the tool is purely ended cutting it has no side rake slight back rake is Metal Lathe Tools On Ebay Usa provided on the tool to promote an easy flow of the ships. A right-hand tool is shown in the figure. Is that which is fed from lathe bed, i. A right-hand tool is formed on its left-hand end when viewed from the top with its nose pointing away from the operator.

The left-hand tool is shown in the figure. Threading tools can add threads to both the interior and exterior of your workpiece. For instance, if you need to make a workpiece that you can thread a screw into, you can use internal threading tools after pre-drilling the hole. If you want to make the screw with threads, you can also do that with external threading tools. Lastly — we have parting tools. Parting tools are also very important, and do much more than their name implies.

These tools can part, groove, and cut off workpieces while offering a consistent, smooth finish. You might also hear about left hand, right hand and neutral hand tooling. That describes how the cutting tool faces the workpiece and what direction your lathe is spinning he work piece.

Normally our lathe will be spinning clockwise. This is also always included in the lathe tooling designation, which you can find engraved into the side of your tool. Boring Bar secured in gang toolholding set up. Drill secured in gang toolholding set up.
