AMG’s R4.5*4°-D16-110-4T carbide taper end mill is specifically engineered for precision slope and curved surface machining on automation equipment parts. Made with HF25 ultra-fine grain carbide substrate, this tool offers outstanding wear resistance and anti-chipping performance, keep stability even under high-load machining conditions. Featuring 4° taper design and R4.5 ball nose transition, with 16mm cutting diameter, 110mm total length, and 4 distributed flutes, it ensures balanced cutting forces, reduced vibration, smooth chip evacuation, and high-quality surface finish. It is particularly suitable for mold slope finishing, deep cavity taper machining, and high-precision curved surface milling in automated equipment parts.

Applications

Widely used for slope, curved surface, and deep cavity taper machining on automation equipment components, molds, medical parts, and automotive parts. It is ideal for materials including steel, cast iron, stainless steel, aluminum alloys, and titanium alloys, making it an excellent choice for precision mold making and automation structural components.

Specifications

Working Principle

This taper end mill use 4° taper to provide greater chip evacuation space and reduce interference risks during deep cavity and curved surface machining, enhancing machining efficiency. The R4.5 ball nose reduces cutting impact and prevents visible tool marks on the workpiece, improving surface finish. The 4-flute design ensures even force distribution during slope and curved surface cutting, allowing for high-speed, high-feed machining while maintaining stability.

FAQ

Q1: Is there a risk of tool breakage when machining slopes and curves with taper end mills?
We recommend step machining with stable clamping systems, which effectively prevents tool breakage. Using coated models further increases durability.

Q2: Can it be used for stainless steel and titanium alloy machining?
Yes, it is fully compatible. We recommend using coated for better performance on these materials.

Q3: How to select the correct taper end mill specification?
Please choose based on your part’s taper angle, cutting depth, and surface radius requirements. If you are not sure, you can send your drawings to AMG’s technical team for assistance.
