Established in 2014, Henan San Kuang Machinery Technology Co., Ltd. operates a state-of-the-art factory spanning 10,000–30,000 square meters and employs 51–100 skilled professionals. With an annual export value of US$2.5–5 million, we specialize in precision machining for heavy industries. Our 3-Axis Gantry Milling Processing for Mining Equipment Mechanical Parts delivers high-accuracy, large-scale machining solutions that meet the rigorous demands of mining operations. Backed by certifications including ISO9001, ISO14000, and OHSAS18001, we ensure every part is manufactured to the highest standards of quality and safety.
This service is designed for producing critical components such as excavator frames, crusher brackets, conveyor rollers, and drill rig bases. Using advanced 3-axis gantry milling machines, we achieve tight tolerances and superior surface finishes, reducing the need for secondary operations. Our dedicated team of engineers and technicians works closely with clients to optimize machining strategies, ensuring cost-effective production without compromising on quality.
Key Features & Advantages
- High Rigidity Gantry Structure: Ensures stable machining of large, heavy workpieces up to 5 meters in length, minimizing vibration and deflection.
- Precision Spindle System: Equipped with high-torque spindles capable of speeds up to 6,000 RPM, enabling efficient cutting of hardened steels and alloys.
- Automatic Tool Changer (ATC): Reduces manual intervention, allowing complex multi-tool sequences to run unattended, shortening cycle times by up to 30%.
- CNC Control with Advanced CAM Software: Supports 3-axis simultaneous interpolation, enabling complex contouring and pocketing operations with accuracy of ±0.05 mm.
- Versatile Material Compatibility: Handles carbon steel, stainless steel, cast iron, aluminum, and specialty alloys commonly used in mining equipment.
- Integrated Quality Control: In-process inspection using CMM and laser measurement ensures every part meets dimensional and surface finish specifications.
- Flexible Batch Sizes: From prototype to mass production, we accommodate both low-volume custom parts and high-volume orders with consistent quality.

Frequently Asked Questions
-
Q: What materials can you machine for mining equipment parts?
A: We commonly machine carbon steel, alloy steel, stainless steel, cast iron, and aluminum. For special alloys like Inconel or titanium, please contact us to discuss feasibility. -
Q: What is the maximum part size you can handle?
A: Our standard gantry mill has a work envelope of 5000×3000×2000 mm (X/Y/Z). Larger parts can be accommodated through special fixturing or sub-assembly machining—please inquire. -
Q: What is your typical lead time?
A: For standard parts, lead time is 30–45 days. Complex parts with multiple setups or tight tolerances may require up to 60 days. Rush orders are available for an additional fee. -
Q: Do you provide material certification?
A: Yes, we can provide mill test certificates (MTC) for all materials used. We also offer full inspection reports including dimensional, hardness, and surface finish data. -
Q: Can you machine parts from customer-supplied material?
A: Absolutely. We can process customer-supplied blanks or raw stock. However, we recommend allowing us to source material to ensure traceability and quality. -
Q: What is the minimum order quantity (MOQ)?
A: We have no strict MOQ for prototypes or small batches. For production runs, we typically suggest a minimum of 10 pieces to optimize setup costs, but we are flexible. -
Q: Do you offer design assistance for machinability?
A: Yes, our engineering team can review your drawings and suggest modifications to improve manufacturability, reduce cost, or shorten lead time. This service is free for confirmed orders. -
Q: How do you ensure quality during machining?
A: We follow a strict quality plan including first-article inspection, in-process checks, and final inspection using CMM, micrometers, and surface roughness testers. All inspection records are kept for traceability.
