Success case | Overcoming Thread Machining Challenges in High-Strength Steel: Key Solutions to Boost Efficiency and Reduce Costs!

🔧 Industry Challenges

With the widespread application of high-hardness, high-strength steel (HRC48-52) in military products, challenging thread machining issues have emerged. Customers using European/American-brand thread milling cutters face problems such as tool deflection, chipping, and insufficient wear resistance, leading to soaring processing costs. SDFTools addresses these issues through structural optimization, achieving 100% extended tool life and 80% reduction in per-hole machining costs compared to traditional methods.

⚙️ Customer Case Background

• Part Type: High-precision housing (36 uniformly arranged circumferential thread holes)

• Key Challenges:
  • 1️⃣ Poor Thermal Conductivity: Material thermal conductivity is only 1/5 of 45# steel, concentrating cutting heat at the tool tip and accelerating wear/chipping.
  • 2️⃣ Tool Deflection Effect: Traditional tools produce “bell-mouth” threads, exacerbating tool wear.

• Performance Requirement: Single tool must complete 144 holes (4 workpieces).

🛠️ SDFTools Innovative Solution

Through structural optimization and coating breakthroughs, we developed a dedicated thread milling cutter for high-strength steel:

✅ Core Thickness Design: Enhanced internal structure improves strength by 30%, resisting chipping.

✅ Unequal Edge Division: Distributes cutting stress, suppresses vibration/deflection, ensuring >99% thread accuracy.

✅ Ultra-Hard Composite Coating: Doubles wear resistance and extends tool life by 2X+!

📊 Test Results Comparison

Parameters: Ø6.5 tool | 35m/min cutting speed | 1350rpm | fn0.02 feed | Cooling: External
