Frequently Asked Questions (FAQ)
Q1: What is the maximum diameter you can machine?
A: Our gear hobbing machines can handle up to 8000 mm in diameter. For larger sizes, please inquire about our custom solutions.
Q2: Which materials do you use for mining and cement gears?
A: We commonly use alloy steels like 20CrMnTi and 42CrMo, as well as carbon steel 45#. Stainless steel and other special materials are also available upon request.
Q3: Can you achieve high precision grades like DIN 5?
A: Our standard accuracy is DIN 6-8. Higher precision (e.g., DIN 5) can be achieved through additional grinding processes; please contact us for feasibility and cost.
Q4: What is the typical lead time for a custom gear?
A: Lead time depends on complexity and quantity. For standard gears up to 3000 mm, it is typically 4-6 weeks. Larger or more complex gears may require 8-10 weeks. We can expedite for urgent orders.
Q5: Do you provide heat treatment services?
A: Yes, we offer carburizing, quenching, tempering, and other heat treatments to meet hardness and wear resistance requirements. Surface treatments like grinding are also optional.
Q6: Are your gears certified for quality?
A: Our factory is ISO9001, ISO14001, OHSAS18001, and other standards certified. Each gear undergoes dimensional inspection, hardness testing, and magnetic particle inspection (if required) to ensure quality.
Q7: Can you produce gears for both mining and cement applications?
A: Absolutely. Our gears are used in crushers, ball mills, rotary kilns, conveyors, and other heavy machinery in mining and cement industries. We have experience with various OEM specifications.
Q8: How do you ship large gears internationally?
A: We ship from Shanghai, Qingdao, Lianyungang, or Tianjin ports. Large gears are securely packed with wooden crates and steel supports, and we can arrange FOB or CIF terms as needed.
