Which materials can be machined by the Fluted Forming Taps
Fluted form taps (also called form taps with oil grooves) are mainly designed for processing materials with high viscosity, high heat generation, and difficulty in lubrication during thread forming. Their built-in oil grooves can deliver cutting fluid directly to the working area, effectively reducing friction, preventing adhesion, and extending tool life. The main materials they process are as follows:
- Stainless Steel: The most suitable material, including austenitic stainless steel (304, 316, 303), ferritic stainless steel (430), and martensitic stainless steel (410, 420). These materials have strong adhesion and high heat generation during forming, and the oil grooves of the taps can solve the problems of sticking and overheating.
- Carbon Steel: Low carbon steel (Q235, 1018) and medium carbon steel (45# steel), especially suitable for deep hole, long thread and mass production scenarios, where the oil grooves can ensure sufficient lubrication and reduce processing torque.
- Titanium Alloys: Such as TC4 and TA2. Titanium alloys have extremely strong viscosity and are prone to cold welding during processing. The oil grooves and low-friction performance of fluted form taps can effectively prevent adhesion and ensure thread precision.
- Copper Alloys: Including brass (H62, H65), red copper, and phosphor bronze. Copper materials are easy to stick to the tap during forming, and the oil grooves can reduce adhesion and improve thread surface finish.
- Aluminum Alloys: Mainly non-high-silicon aluminum alloys such as 6061, 6063, and 7075. Although ordinary form taps can process aluminum alloys, fluted form taps are more suitable for deep hole and long thread processing to avoid sticking and thread damage.
- Zinc Alloys and Magnesium Alloys: Such as Zamak 3/5 zinc die-casting alloys and AZ31B/AZ91D magnesium alloys. These materials have low melting points and are easy to stick to tools, and the oil grooves of fluted form taps can ensure stable processing.
