High Efficiency Finishing Special Shape Tool Series GS4TN

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 highlights the tool's efficiency, surface finish quality, and versatility in machining tilted and fillet sections with a single tool.

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

Performance Evaluation: The GS4TN10-50R-TH3 model demonstrated six times the efficiency of a 2-flute ball end mill in tilted section finishing. It achieved a surface roughness of Ra 0.38μm and 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 ensure proper regrinding to prevent tool breakage. Safety measures include using safety covers and wearing protective gear due to the presence of cobalt in the tool.

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).

Usage Recommendations: For optimal performance, use machines with high rigidity and accuracy, adjust parameters based on actual conditions, and ensure appropriate coolant use. The document also notes that the tool is not compatible with regrinding and suggests using the GP1T indexable end mill for larger diameters.

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

Specifications and Tool Design: The document discusses the GS4TN type high-efficiency finishing special shape tool series, specifically the 2 flutes ball end mill GS4TN10-50R-TH3. The tool features a unique design with a "Barrel R" that connects the "tip R" and tool diameter using 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.

Machining Procedures: For 5-axis machines, the barrel R allows cutting of tilted sections with large pitch, reducing machining steps. For 3-axis machines, it enables cutting steep faces but requires a separate tool for bottom corners. The document provides specific cutting conditions for different materials, including carbon steel, alloy steel, and various hardness levels of hardened steel.

Performance Evaluation: Field data from model machining of YXR33 with a 5-axis machine shows significant efficiency improvements. The GS4TN tool achieved six times the efficiency compared to traditional methods, with good surface roughness even at large pitches.

Safety and Handling Recommendations: The document emphasizes safety precautions, including checking tools for damage before use, using safety equipment to prevent injury from flying chips, and handling tools carefully to avoid contact with sharp flutes. It also highlights the importance of adhering to local regulations when handling cobalt-containing tools.

■ 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.
