Specification:



Aplication:
XHC151:Substrate with excellent wear-resistance,in combination with MT-Ti(CN),thick layer AL2 O3, TiN coating.It is an ideal grade for the finishing steel,cast steel and stainless steel under gigh speed and dry machining.
XHC251:Cutting edge with special strength and toughness,in an optimal combination with MT-Ti(CN),thick layer AL2 O3,Tin coating.itis a suitable grades for a wide application.It is good for the finishing.Semi-finishing and Light roughing of steel,cast steel and stainless steel.
XHC351:Substrate with high strength and resistance against plastic deformation,in combination with MT-Ti(CN),thick layer AL2 O3,TiN coating.It is suitable for light roughing and roughing steel,cast steel and stainless steel.
XHM151:Substrate with special structure,in combination with Ti(CN),thin layer AL2 O3,TiN coating .Withthe resistance against diffusion wearness and plastic deformation,it is good for finishing and semi-finishing(turning as well as boring)of stainless steel.
XHM251:Substrate with good toughness and stength,in combination with Ti(CN),thin layer AL2O3,Tin coating .It is a premium grade for semi-finishing to light roughing (turning and boring) of stainless steel at continuous and intermittent machining conditions.
XHM351: Ti(CN),thin layer AL2 O3,Tin coating with very good strength and impact resistance.It is suitable for roughing turning of stainless steels at low to moderate cutting speed or interrupted cutting,also for high cutting speed and heavy cutting in P30 area.
XHG102: in combination with PVD TiN,TiAIN coated carbide grade.Suitable for finish machining of cast iron.
XHG151:In combination with PVD TiN,TiAIN coated carbide grade.Suitable for semi-finish turning of cast iron.
XHG252:In combination with PVD TiN,TiAIN coated carbide grade.Suitable for rough machining of cast iron.
XHD252:In combination with PVD TiN,TiAIN coated carbide grade.Suitable for rough machining of hard cast iron,nodular cast iron.

MaterialMaterial 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.
