Product catalog summary

Safety Precautions

Handling: Exercise caution when removing tools from packaging to avoid dropping or contact with sharp flutes.
Mounting: Inspect tools for damage before use and ensure they are securely mounted. Stop use immediately if abnormal chattering occurs.
Use: Confirm tool dimensions and rotation direction. Adjust cutting conditions based on material and machine rigidity. Use safety covers and goggles to protect against flying debris and sparks.
Regrinding: Perform regrinding timely to prevent tool breakage. Follow safety protocols for handling cobalt-containing materials.

Product Specifications

The SCE-R Ceramic End Mill is designed for high-efficiency machining of superalloys, achieving cutting speeds up to 800 m/min.
Utilizes silicon nitride ceramics for heat resistance, allowing operation at temperatures exceeding 1000°C.
Available in diameters from 6mm to 12mm, with specific flute and corner radius configurations.

Recommended Cutting Conditions

Use dry cutting methods and appropriate holders for optimal performance.
Gradual cutting depth increase is advised to prevent tool damage.
Maintain a finishing allowance of at least 0.2mm to account for heat-affected layers.

Performance Comparison

Ceramic end mills offer over five times the machining performance and three times the chip removal volume compared to carbide end mills.

Contact Information

For further details, contact MMC Hitachi Tool Engineering offices in Japan, Europe, USA, Mexico, China, Thailand, or India.

Handling and Safety Precautions:
1. When removing tools from packaging, ensure they do not pop out or drop. Avoid direct contact with sharp cutting flutes.
2. Before use, inspect tools for damage and ensure they are securely mounted. If abnormal chattering occurs, stop the machine immediately.
3. Confirm tool dimensions and rotation direction before use. Adjust cutting conditions based on material and machine rigidity.
4. Use safety equipment like goggles and covers to protect against flying debris and potential fire hazards.
5. Do not use tools for unintended purposes.

Usage Recommendations:
1. Use standard cutting conditions as a starting point and adjust as necessary.
2. Employ dry cutting methods and use appropriate holders like hydro chucks.
3. Prefer continuous cutting and avoid interrupted cutting.
4. Gradually reach the set cutting depth to prevent tool damage.
5. Allow for a finishing allowance of at least 0.2 mm due to potential heat-affected layers.

Regrinding and Maintenance:
1. Perform regrinding at appropriate times to prevent tool breakage.
2. Use safety covers and wear protective clothing during regrinding.
3. Handle cobalt-containing products according to local regulations.

Product Specifications and Contact Information:
Specifications are subject to change without notice. For more information, visit the official website or contact regional offices in Japan, Europe, USA, Mexico, China, Thailand, and India.

Performance Data:
1. Ceramic end mills offer over five times the machining performance and three times the chip removal volume compared to carbide end mills.
2. Recommended for side milling using Ni-based superalloys.

Achieves high-efficiency machining for superalloy! Achieves cutting speed of vc=800m/min.! Achieves ultra-high-efficiency machining for superalloy. The tools employ a special silicon nitride ceramics with excellent heat resistance that can withstand flute tip temperatures of more than 1000°C. Cutting can be performed at much higher speeds than are normally used. By achieving cutting in the softening temperature region of the work material, tool life is greatly improved. for Superalloy Parts processing

Features Cutting P6gion of Coramic End Mill (Softening temp. region of superalloy) 700 Superalloy known as a difficult-to-cut material is a material that shows high strength even up to high temperatures, but when it reaches 1000 °C or more, the material softens. High speed cutting increases the cutting heat, and the cutting force of superalloy becomes almost the same as that of stainless steel. In other words, the ceramic end mill that enables cutting in this temperature range realizes ultra-high-efficiency machining, greatly improving tool life.
