Carbide Turning Inserts for Heat Resistant Alloys Turning with Ultra High Temperature Resistance

Application:

• ISO S materials, preferred for general-purpose turning of Heat Resistant alloys.

Technical Information:

• Material Classification: S1.0 - 3.0
• Heat resistant alloys can be divided into three groups:
  • Nickel-based alloy:
    • The most widely used. More than 50% of the weight in aircraft engines is made of nickel-based alloys. Typical materials are Inconel 718, 706 Waspalloy, Udimet 720, etc.
  • Iron-based alloy:
    • Iron-based alloys have evolved from austenitic stainless steels with the highest temperature strength characteristics.
  • Cobalt based alloy:
    • Cobalt-based alloys have the best high temperature properties and corrosion resistance and are mainly used in the medical industry.
    • State: annealing, solution treatment, aging, rolling, forging, casting.
    • Characteristics: Increased alloy content (Co, Ni), which has better heat resistance and higher corrosion resistance, and increased tensile strength.
  • Machining performance:
    • Due to the chemical nature of the alloy and the specific smelting process used in the manufacturing process, the physical properties and processing properties of each material vary considerably.
    • Annealing and aging treatment have a large impact on subsequent processing characteristics.
    • Dust control is difficult.
    • Cutting force and required power are very high.
    • The processing difficulty of cutting performance increases in the following order: iron-based alloy, nickel-based alloy, cobalt-based alloy.
    • All materials have high strength at high temperatures and produce jagged chips during the cutting process, which results in high dynamic cutting forces.
    • Poor thermal conductivity and high strength during processing can cause high temperatures. The high strength, work hardening and adhesion hardening properties result in groove wear at the maximum depth of cut and the cutting edge in an extremely harsh environment.
    • In general, use a small lead angle blade, such as a round blade, and select the positive rake insert geometry.
    • Always use coolant. The coolant flow should be high and spray directly onto the cutting edge.

Feature Advantage:

• Chipbreaker SR:
  • The insert surface is smooth, the chip is smooth, and the chip breaking is good.
  • The cutting edge is sharp and the cutting resistance is small, which can effectively reduce the groove wear.
  • The cutting edge adopts a variable rake angle design to increase the edge strength at large depth of cut. As the depth of cut increases, the edge strength increases.
  • The large groove width combined with the unique edge reinforcement design not only has excellent chip breaking performance, but also effectively improves the edge strength.

• Grade:

• Types:
  • ISO standard turning inserts are available in a variety of conventional types
  • Different insert arcs of various specifications (R0.2, R0.4, R0.8, R1.2, etc.)

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 the material being processed
  • 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 processing efficiency
