DCMT Indexable Lathe Tool tooling Inserts for toolholder SDJCR/L
Describtion:
Turning inserts employ highly engineered composite structures, coatings, and geometry features to achieve great accuracy and high material removal rates. The benefits of using replaceable inserts for turning tools include: ·
1. Some inserts can be indexed to use other edges when one becomes worn ·
2. Inserts are quickly and easily replaced at the machine
Turning tool is the most widely used tool in metal cutting without signature.It can be machined on lathe outside circle, end plane, thread, internal hole, also can be used for cutting groove and cutting.On the structure, the tool can be divided into integral tool, welding assembly tool and mechanical clamping blade.Mechanical clamping blade's turning tool can be divided into machine tool turning tool and indexable turning tool.The cutting performance of mechanical clamping tool is stable, and workers do not have to grind it, so it is applied more and more in modern production.

Turning, also known as "turning for grinding", refers to the turning of hardened steel as the final finishing process.In general, the rough processing of hardened steel workpiece is carried out before quenching, and after quenching grinding finishing.With the development of high-hard tool materials and related technologies, PCBN tools, ceramic tools or new types of cemented carbide tools can be used to turn hardened steel in the lathe or turning processing center, and the processing quality can also reach the level of fine grinding.
Compared with CBN and ceramic materials, new cemented carbide and coated carbide tool materials have higher bending strength and impact toughness and lower price, which can be used to process hardened steel workpieces with hrc40-50 hardness.The choice of the shape of the blade and the geometrical parameters is very important to give full play to the cutting performance of the cutter.For blades of various materials, the shape of blades with high strength and good heat dissipation condition should be selected, as well as the radius of tip arc as large as possible.The main feature of the tool geometry is to select the larger negative front Angle or the pre-ground negative chamfer.
