Square End Mill – GTU Series For Titanium

Flat End Mill –  GTU Series For Titanium

The GTU Titanium Series is a top-tier professional tool. With heat control as the core, it solves titanium machining challenges through a tough tool body, special coating and optimized geometric design. It provides a key guarantee for safe, efficient and high-quality titanium machining.

General Tool Type (Flat-End Mill)

• Core Functions: 2D contour cutting, flat surface machining, grooving;
• Features: High edge strength, excellent at machining 90° vertical sidewalls and corner cleaning;
• Analogy: Similar to a painter’s brush, it efficiently handles large-area flat surfaces with clear edge effects.

Core Analysis of GTU Titanium Series

• Product Positioning: The “GTU” in the name clearly indicates it is a top-tier tool exclusively for titanium machining.
• Challenges in Titanium Machining (for materials like TC4/Ti-6Al-4V):
  • High strength and toughness, resulting in much higher cutting force than steel;
  • Poor thermal conductivity, with over 80% of heat concentrated at the cutting edge, easily causing tool wear;
  • High chemical activity at high temperatures, prone to reacting with tool coatings and generating diffusion wear;
  • Low elastic modulus, leading to part “deflection” which affects precision and intensifies tool vibration;
  • A hardened layer is easily formed on the machined surface, increasing the difficulty of subsequent cutting.
• Design Highlights & Functions of GTU Series:
  • Super Tough Tool Body: Made of ultra-fine grain high-toughness cemented carbide, resistant to cutting force and thermal shock, preventing edge chipping and breakage;
  • Special High-Temperature Resistant Coating (core technology): Mostly AlCrN or enhanced TiAlN+ coatings, with high temperature resistance and strong chemical inertness, preventing diffusion wear and blocking heat conduction;
  • Optimized Geometric Design: Small rake angle + positive axial rake angle ensure edge strength, thickened core improves rigidity to prevent vibration, special chip flutes balance chip evacuation and heat dissipation, and the edge is reinforced to prevent micro-chipping;
  • Heat Control Design Concept: Reduce cutting force and frictional heat generation through precise rake angle, flute shape and edge treatment.

Application Scenarios

• Aerospace: Key titanium components such as engine blades and casings;
• Medical: Medical-grade titanium parts like artificial joints and bone plates;
• High-end Manufacturing: Titanium frames for racing cars and bicycles;
• Chemical & Marine Engineering: Corrosion-resistant titanium valves and pipe fittings.
