Overview

This document details the GP1LB type high-efficiency finishing indexable special shape tool series, designed for precision machining with enhanced surface finish and productivity. It covers technical specifications, handling instructions, cutting parameters, and support information for machining various materials including stainless steels, cast irons, and hardened steels.

1. Handling and Usage Instructions

• Handle, mount, and use tools carefully to maintain performance and safety.
• Avoid applying lubricants such as grease on contact faces and modular screws.
• Drivers and screw anti-seizure agents are sold separately to minimize environmental impact.
• Use appropriate coolant and ensure chip removal by air blow to prevent tool damage.
• Replace inserts promptly to avoid breakage and maintain tool integrity.

2. Product Specifications and Components

• The series includes modular mill special shanks (carbide shanks) in A and B types with detailed dimensions (diameters, lengths, radii, thread sizes).
• Combination tools fuse lens and barrel geometries, reducing cusp height by approximately 50% compared to ball end mills, resulting in smoother surfaces (Ra 0.36μm vs. Ra 0.8μm).
• Tools are compatible with Alpha Ball Precision F (ABPF type) holders.
• Insert types (e.g., ZPHW160-LB16, ZPHW200-LB20) are specified with item codes, stock status, and recommended grades.
• Clamp screws, wrenches, and anti-seizure agents have defined dimensions, grades, and recommended fastening torques.

3. Cutting Conditions and Recommendations

• Cutting parameters are provided for various materials (carbon steels, alloy steels, stainless steels, cast irons, hardened steels) with hardness ranges from under 30HRC to 62HRC.
• Parameters include spindle speed (n), cutting speed (vc), feed rate (vf), feed per tooth (fz), axial depth of cut (ap), and radial depth of cut (ae), adjusted by tool diameter and workpiece hardness.
• Separate cutting conditions are given for lens and barrel parts of the tool.
• Overhang length adjustments are recommended when exceeding 3 times the cutter diameter (3Dc).
• Use of coolant appropriate to the material and machining shape is advised.
• Chip removal by air blow is mandatory to prevent clogging and tool damage.

4. Performance Highlights

• Fusion of lens and barrel tool geometries enables machining of gently curved and wall surfaces with a single tool.
• Significant reduction in cusp height improves surface finish quality.
• High precision radius accuracy of ±0.01 mm ensures consistent machining results.

5. Environmental and Additional Notes

• Printing uses vegetable oil ink to reduce environmental impact.
• Drivers and anti-seizure agents are sold separately to minimize environmental footprint.
• Prices exclude consumption tax and are subject to change without notice due to improvements or specification changes.
• Patent pending status is noted for the tool series.

6. Contact and Support Information

Technical consultation and tool selection databases are available online. Multiple regional sales offices and international branches provide support and sales services across Japan, Europe, China, USA, Thailand, and India.

7. Summary Table Highlights

• Tool diameters range from 16 mm to 32 mm with various shank types and lengths.
• Insert radii range from 0.36 mm to 0.49 mm, correlating with cusp heights and cutting parameters.
• Cutting speeds vary from 220 m/min to 720 m/min depending on material and tool size.
• Feed per tooth ranges from 0.05 mm/t to 0.25 mm/t, optimized for surface finish and tool life.

Note: Actual machining conditions should be adapted based on machine capabilities, workpiece geometry, and desired outcomes.
