Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›The Taixing Hongyuan Cnc Machine Co., Ltd supplies the HY-6 model drill pipe inner hole grinding machine, designed to restore the internal bore of drill pipes after friction welding. The machine targets the transitional zone where upset material from welding creates irregularities, typically 10 to 50 mm in length along the pipe’s interior. It operates with PLC automation to ensure consistent material removal without manual intervention.
The system uses precision grinding wheels with diamond or CBN abrasives, capable of achieving surface finishes below Ra 0.8 micrometres. Typical industry standards for internal bore finish after repair require roundness within 0.05 mm and cylindricity under 0.1 mm per metre. The machine is built for pipes with diameters from 114 mm to 203 mm, matching common oilfield drill pipe sizes. Dust extraction is integrated to reduce operator exposure to metal particulates.
Buyers are primarily drill pipe repair shops, offshore service contractors, and rig maintenance teams in North America, the Middle East, and Southeast Asia. The machine is suitable for both shop-floor and field repair applications. Buyers should confirm the maximum pipe length supported, the wheel replacement cycle, and whether the system includes a built-in measurement probe for post-grind verification. Packaging is in a steel frame crate with shock-absorbing mounts.

Before ordering, confirm the maximum pipe length and internal diameter the machine can handle, as well as the required compressed air pressure and electrical input. Verify the PLC software version and whether it supports custom grinding profiles for non-standard pipe grades. Request a video demonstration of the machine operating on a sample pipe with known bore irregularities.
Logistics are typically shipped in a steel crate via sea freight, with the machine partially assembled. Lead time is not stated and must be confirmed directly. Incoterms are not provided - buyers should negotiate FOB Taixing Port or CIF destination. Payment terms should include a 30% deposit and 70% balance against pre-shipment inspection. Ensure the supplier provides installation drawings and foundation load specifications.
Quality verification must include a pre-shipment test run on a representative pipe sample, with documentation of surface finish, roundness, and dimensional tolerances. Request calibration certificates for all measurement instruments used in the test. Inspect the grinding head for wear, check the dust extraction system for leaks, and confirm all safety interlocks function. Accept only machines with visible serial numbers and manufacturer plates.
