Frequently Asked Questions
Minnuo’s thread rolling machines can form metric threads, inch threads, trapezoidal threads, knurling, splines, and custom straight/diagonal patterns, suitable for a wide range of fasteners and shafts.
Thread rolling works best on mild steel, carbon steel, stainless steel, copper, aluminum, and titanium alloys. It is ideal for materials with good plasticity and cold-forming properties.
Thread rolling provides stronger threads, faster production, better surface finish, and no chip waste. It also improves fatigue resistance and dimensional consistency.
Yes! Just send us your product drawings or basic specifications (thread type, material, diameter, length), and we’ll recommend the right thread rolling machine model within 10 minutes.
Absolutely. We offer customization for thread pitch range, roller type, rolling force, control system (manual, hydraulic, CNC), and automatic feeding systems to suit your production needs.
We use hardened and ground guideways, servo or hydraulic pressure control, and calibration through sample test rolling, with dimensional inspection reports provided before delivery.
Standard models are delivered in 10–15 working days. Custom-built or automated models typically require 20–30 working days, depending on complexity.
Minnuo provides a one-year warranty, 24/7 technical support, video training, on-site assistance, and lifetime spare parts support.
