Indexable Cutting Tools Cemented Carbide Inserts DNMG For DDJNR/PDJNR Holder
Application:
| 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 |

Description:
CNC carbide turning inserts is the general name of the indexable turning insert, and it is the mainstream product in the application field of modern metal cutting.It is mainly used in metal turning, milling, cutting groove and thread cutting.
There are five kinds of CNC blades: integral type, Mosaic type, shock absorber type and special type.
It is mainly used in metal turning, milling, cutting groove and thread cutting.According to the material can be divided into coating blade, metal ceramic blade, non-metal ceramic blade, carbide blade, super-hard blade and so on.It is characterized by high efficiency, high wear resistance, more than four times higher than the traditional welding blade, alloy blade machining efficiency.With the continuous progress of coating technology, the breakthrough of key technologies of wear-resistant and high-temperature resistance will further improve the efficiency and reduce the processing cost.
Carbide inserts are replaceable and usually indexable bits of cemented carbide used in machining steels, cast iron, high temperature alloys, and nonferrous materials. Carbide inserts allow faster machining and leave better finishes on metal parts. Carbide inserts can withstand higher temperatures than high speed steel tools.
