It is suitable for all kinds of turning tools, especially for small tools. It is a commonly used tool in CNC lathe, and the cutter bar can be reused. High-speed steel tool: it is made of high speed steel and can be ground continuously, a general cutter for rough machining and semi finish machining.
Carbide tool: the blade is made of carbide, which is used to cut cast iron, non-ferrous metal, plastic, chemical fiber, graphite, glass, stone and ordinary steel. It can also be used to cut heat-resistant steel, stainless steel, high-speed steel, tool steel and other difficult materials.
Diamond: diamond blade has the advantages of high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals. It can be used for precision machining of non-metallic brittle and hard materials such as graphite, high wear-resistant materials, conforming materials, high silicon aluminum alloy and other non-ferrous metal materials.
Other materials, such as cubic boron nitride tool and ceramic tool, are developing towards rough machining and intermittent cutting of high hardness alloy cast iron. Lathe Machine and Operations. Classification by Use. Turning Tool Turning tools are designed for removing the materials from the stock, a rough turning tool is used to remove the maximum amount of material and the finishing turning tool is serve for good surface quality, just remove a small amount, to make the piece more accurate.
Boring Bar A boring bar is required when you want to make an existed hole bigger, a boring bar can easily bore into the hole that is already drilled, and widen its diameter. Chamfering Tool Chamfer is a transitional edge between two faces of an object, also defined as a form of the bevel. Knurling Tool Knurling tools are used to produce knurled lathe parts, through creating or pressing a pattern onto a round section, used as a grip for a handle, also usually created on fasteners like nuts.
There are various types of cutting tools available in the machining industry. The process requires the cutting tool properties to be made up of different materials. Each cutting tool is selected by the type of material to be machined, including the type of machining, quantity, and quality of production. Single-Point or multipoint tools are used to accomplish cutting.
Single-point tools are used in turning, planing, and other similar methods to remove material utilizing one cutting edge. End Mills are the most common cutting tools for CNC and manual mills and are generally used for machining the sides and faces of a workpiece. 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.
