Precision Ground Negative Carbide Inserts CNMG With Diffirent Chipbreaker
Description:
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.

| 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

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. |
