SCBN TOOLS CBN Inserts Easily Overcome the Pain Points of Machining High Manganese Steel Hammerheads

High-manganese steel, due to its excellent impact resistance and wear resistance, has become the core material for crusher hammers in industries such as mining. Its processing conditions are harsh, requiring extremely high precision and quality.

I. Core Pain Points in Machining High-Manganese Steel Crusher Hammers

High-manganese steel hammers are mostly large-section castings with poor cooling conditions, resulting in significant pain points when machining with traditional tools:

1. Severe work hardening, accelerating tool wear and chipping.

2. High cutting force requirements, easily leading to tool deformation and tip wear.

3. High cutting temperature and low thermal conductivity, causing heat accumulation on the cutting edge and shortening service life.

4. Prone to thermal deformation at high temperatures, leading to dimensional deviations and insufficient surface flatness.

5. Difficult chip breaking, affecting efficiency and scratching the workpiece surface.

II. Core Advantages of SCBN TOOLS CBN Inserts Machining

1. Extreme hardness and wear resistance, resisting work hardening

2. Excellent high-temperature red hardness, suitable for high-load conditions

3. High impact toughness, handling complex working conditions

4. Precision machining, ensuring accuracy and surface quality

5.High efficiency and energy saving, reducing overall costs

III. Inserts Selection

Rough Machining: Use SNGN or RNGN series solid CBN inserts. These inserts offer high edge strength and excellent impact resistance, suitable for cutting large allowances and addressing casting defects in high-manganese steel hammerheads.

Semi-finishing/Finish Machining: Use CNGN or RCGV series high-precision PCBN inserts. These inserts offer high dimensional accuracy and good cutting stability, ensuring precise hammerhead dimensions and surface finish.

IV. Application

A mining machinery company used this technology to process ZGMn13 high-manganese steel hammerheads (manganese content 15.0%~19.0%, maximum thickness 160mm). The results after replacing traditional cutting tools were significant:

1.Processing efficiency increased by 60%, reducing single-piece processing time from 8 hours to within 3 hours;

2.Tool life increased by 8-10 times, allowing for the processing of 10-15 pieces/hammer (compared to only 1-2 pieces traditionally);

3.Processing quality met standards, with hammerhead assembly accuracy and service life improved by 30%;

4.Overall processing costs decreased by 40%.
