ISO Indexable Turning Carbide Insert From Chinese Manufacture
Description:
A carbide insert is a cutting tip used on a larger tipped tool whose shank is made of another material, usually carbon steel. This offers the benefits of a carbide cutting interface without the high cost and brittleness of making the entire tool out of carbide.
Product Group : | turning inserts |
| Classification : | INDEXABLE TURNING - INSERTS |

| 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. |
Application:
Choose between the following options to find the best grade and
chipbreaker for your turning operations
Workpiece material:P steel;M stainless steel;K cast iron
Workpiece condition:Continuous Cutting;Light Interrupted Cutting;Heavy Interrupted Cutting
Roughing or Finishing:Finishing or Precision Cutting;Medium Cutting;Medium to Heavy Cutting.
| The Chipbreaker Instruction of Carbide Indexable CNC Turning Inserts | |
| DF | Chip-breaker with special angle design can make cut easy,control chip and get good surface quality. |
| DM | Widely used chip-breaker is used for semi-finishing and finishing machining steel and stainless steel. |
| DR | Special chip-breaker with high toughness cutting edge can reduce cutting force. |
| PM | With stronger cutting edge,it is better for intermittent cutting than -DM,with widely cutting zone of P type material. |
| HF | With sharp cutting edge,used for finishing machining inner hole,fine finishing surface can be got with small feed rate. |
| HM | With sharp wave cutting edge to reduce cutting force,it is the first choice for semi-finishing machining of inner holes and can make chip flow smoothly. |
| HR | With tough cutting edge,used for roughing/machining of inner hole and intermittent machining workpiece with irregular surface. |
| LH | Mainly recommended for finish turning,Typical parts: Ordinary aluminum parts. |
