Original Raw Material Compression Moulding SNMT1305 Tungsten Carbide Cnc Inserts
Application:
Carbide-tipped CNC turning blades have excellent cutting performance and are widely used in CNC turning.Carbides CNC turning tools have standard specification series of products, specific technical parameters and cutting performance provided by the tool manufacturers.
CNC turning carbide according to the international standard is divided into three categories: P class - chip is suitable for machining steel, long malleable iron (equivalent to our country's YT classes), M class - suitable for processing of austenitic stainless steel, cast iron, high manganese steel, alloy cast iron (YW) of our country, such as K class - chip is suitable for processing cast iron and chilled cast iron, short malleable cast iron, the titanium alloy (equivalent to our YG class)
| Material | Material Characteristics |
| Carbon Steel, Alloy Steel and Tool Steel 36-48 HRC: | • Higher carbon content • Higher chrome, nickel, and moly content • Tough material to machine • Abrasive • Difficult to break and control the chip flow • The material surface will harden when machined at high speed • Good surface finish |
| Ferritic, Martensitic, and PH Stainless Steel under 48 HRC | • Brittle • Stringy chips • High cutting force • The material will harden when machined at high speed. |
| Austenitic Stainless Steel: | • Becomes gummy under machining operations due to nickel content • Very difficult to machine in soft conditions • Very difficult to machine at a small depth of cut • Develops a tough string of chips that are difficult to control. Forms a build-up on the insert tip • Low thermal conductivity results in excess heat at the insert tip • Material surface will harden due to high chromium content |
| Ductile and Malleable Cast Iron | • Very difficult to machine • Small depth of cut • Spherical form graphite makes machining difficult • The carbide concentration creates hard spots • The material structure is not uniform • The crater wear and flank of the insert makes machining difficult • The insert tool life is less than gray cast iron |
| Gray Cast Iron | • Flake form of graphite makes machining easy • Contains scale, inclusions and sand in the surface • The material will break easily on the end of the cut • Tendency to chatter and vibrate on thin wall section • Chucking and rigidity of the workpiece is extremely important to minimize distortion, to achieve a good finish and close tolerance |
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.
