GS4TN type

Product catalog summary

Overview: The document introduces the GS4TN type solid end mill, part of the High Efficiency Finishing Special Shape Tool Series, designed for 5-axis machining. It emphasizes the tool's efficiency, surface finish quality, and versatility in machining complex shapes.

Specifications: The GS4TN series features a high helix shape to reduce cutting force and improve efficiency with 4 flutes. It is available in various sizes, with tip radii ranging from 0.5mm to 2mm and overall lengths from 50mm to 100mm. The tool is coated with TH3 for extended life.

Machining Performance: The GS4TN tool demonstrated a sixfold increase in efficiency compared to a 2-flute ball end mill. It can finish tilted and fillet sections with a single tool, achieving good surface roughness (Ra: 0.38μm, Rz: 2.57μm) even with large pitch cutting.

Safety and Handling: Users are advised to inspect tools for damage before use, stop the machine if abnormal chattering occurs, and handle tools carefully to avoid injury. Regrinding should be performed timely to prevent tool breakage, and safety measures should be in place to handle grinding dust and chemical substances.

Recommended Cutting Conditions: The document provides detailed cutting conditions for various materials, including carbon steel and hardened steel, with specific recommendations for revolution speeds and feed rates based on the tool's section in use (Barrel R and Tip R).

Contact Information: The document lists contact details for MMC Hitachi Tool Engineering offices in Japan, Europe, the USA, China, Thailand, and India for further inquiries and support.

Specifications and Tool Design: The document discusses the GS4TN type high-efficiency finishing special shape tool series, specifically a 2-flute ball end mill. The tool features a unique design with a 'Barrel R' and 'Tip R' that connect via a double arc, enhancing machining efficiency and quality. The tool employs a high helix shape and TH3 coating for reduced cutting force and extended tool life. It is not compatible with regrinding, and for larger diameters, the indexable end mill 'GP1T' is recommended.

Cutting Conditions and Recommendations: For optimal performance, the document provides specific cutting conditions for different materials, including carbon steel, alloy steel, and various hardness levels of hardened steel. It emphasizes the importance of selecting appropriate cutting conditions based on the contact section, either 'Barrel R' or 'Tip R'. The tool is suitable for both 5-axis and 3-axis machines, with specific advantages for each.

Safety and Handling Instructions: Safety precautions include checking the tool for damage before use, ensuring proper mounting, and wearing safety equipment to prevent injury from flying chips or tool breakage. The document also highlights the risks associated with regrinding, including the handling of cobalt and its compounds, and advises adherence to local regulations.

Performance and Efficiency: The GS4TN tool is noted for its high efficiency in finishing tilted sections and fillet sections with minimal machining steps. Field data indicates significant efficiency improvements compared to traditional 2-flute ball end mills, with good surface roughness achieved even with large pitch cutting.

Contact and Additional Information: The document provides contact details for Mitsubishi Hitachi Tool Engineering's offices worldwide and directs users to their online tool selection database for further information.

■ About tool shape "Barrel R" of GS4TN has a shape that connects "tip R" and "tool diameter" with double arc. See the figure on the right. Interface between tip R and barrel R [Note] appropriate coolant for the work material and machining shape. ©Use a machine having as high rigidity and high accuracy as possible. ©These conditions are for general guidance; in actual machining conditions adjust the parameters according to your actual machine and work-piece conditions. ©If the rpm of the machine is low, lower the feed rate also to put the rpm and feed rate in the same ratio.
