Any machine tool is only as good as its tool. If the drills, lathe tools and milling heads wear out, regrinding is a must! Tool grinding machines keep the tool sharp and bring it back into shape. Tool grinding machines can also be used for tool production. To be able to machine any complex tool geometry, a conventional or CNC tool grinding machine usually has 5 axes. At Surplex you will find used tool grinding machines from the best manufacturers. Other grinding machines, grinding wheels and other accessories are also available - all used, but of high quality! Buy & sell used tool grinding. A machine tool is a machine for shaping or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformation. There are many ways to machining mechanical parts in modern machinery manufacturing. In addition to cutting, there are casting, forging, welding, stamping, extrusion, etc., but those who require high precision and surface roughness requirements of the smaller parts, generally need to be cut on the machine tool for the final processing.  A lathe is a machine tool that mainly rotates the workpiece with a turning tool. You can also use the drill, reaming drill, reamer, tap, die and knurling tools to complete the corresponding processing in the lathe.

These modernized machines can contribute to all types of heavy-duty lathe requirements involving metal, leather, etc. 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 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 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 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. Is that which is fed from the Left to the right-hand end of the lathe bed, i. The left-hand tool is used for left-hand thread cutting operation or turning operation which leaves a shoulder on the right-hand end of the workpiece.

A left-hand tool has its cutting edge formed on its right-hand end when viewed from the top with its nose pointing away from the operator. A round nose turning tool sown in the figure. Maybe fed from left to the right or from right to the left-hand end of the lathe bed away. For this reason, they have no back rake and side rake.

In some cases, a small back rake is provided on the tool. A round nose turning tool is usually used for finish turning operation. If you found this article helpful please share with your friends.
