Finishing Cemented CTCMT Carbide Inserts TCMT16T304PF , Circle Carbide Inserts 

Carbide Turning Inserts TPGH Serials for Internal Precision Boring

Application:

• Precision boring.

Feature Advantage:

• The unique cutting edge skeleton design achieves the perfect combination of blade toughness and resistance to plastic deformation.
• The blade adopts special surface technology, which greatly improves the surface quality of the insert, effectively reduces the cutting force, reduces the bonding between the insert surface and the material to be processed, and greatly improves the stability of the insert.
• With special sintering technology, the impact resistance and wear resistance of the cutting edge are enhanced to improve the resistance of the cutting edge.

• Grades:

• Types:
  • ISO standard turning inserts are available in a variety of conventional types

Technical Information:

• Steel is the most common material in metal cutting.
• Generally, steel has good machinability, but the specific properties vary greatly depending on the hardness of the material and the carbon content.
• The machinability of steel varies depending on its alloying elements, heat treatment and manufacturing processes (forging, casting, etc.).
• Steel generally has the following three categories:
  • Non-alloy steel:
    • Material classification: P1.1
    • Non-alloy steels include steels with a carbon content of 0.55% or less.
    • For non-alloy steels with higher carbon content, the processing characteristics are similar to those of low alloy steels.
    • For low carbon steel (<0.25%), due to the difficulty of chip breaking and the tendency of bonding, special care should be taken during processing.
  • Low-alloy steel:
    • Material classification: P2.x
    • Low alloy steel is the most commonly used material in metal cutting. These materials are either soft or hard (less than HRc 50).
    • The machinability of low alloy steel depends on the alloy content and heat treatment (hardness).
    • For low hardness materials, the most common types of wear are crater wear and flank wear.
    • Hard material cutting tools require extremely high heat and flank wear resistance, so for these processes, cast iron machining grades can be used.
    • Hard materials generate more heat in the cutting area, so plastic deformation is a common type of wear.
  • High alloy steel:
    • Material classification: P3.x
    • High alloy steels include carbon steel with a total alloy content of more than 5%.
    • High alloy steel includes both soft and hard materials (below HRc 50).
    • Cutting performance decreases as the alloy content and hardness increase.

Recommended Cutting Parameters:

• The following cutting parameters are the recommended range values. Appropriate adjustments and selections should be considered after considering the following factors:
  • Specific physical properties of steel
  • The actual condition of the part blank
  • Power and rigidity of the machine tool
  • Clamping rigidity of tools and workpieces
  • Balance between tool life and machining efficiency
