ISO Indexable Turning Carbide Insert From Chinese Manufacture




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.

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.



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.
