Line Boring Machine Portable
Versatile Application: Ideal for repairing and re-machining worn holes in excavators, cranes, loaders, and presses. Commonly used for hole finishing post-welding, bushing installation after reaming, and restoring alignment in structural joints.
Easy Installation & Portability: Combines bolted and welded clamping mechanisms for rapid mounting and disassembly. Lightweight construction facilitates transport and is optimized for mobile machining needs.
High-Precision Cutting System: The boring shaft and linear guides are built from heat-treated 45# steel, finished with grinding and hard chrome for excellent durability and precise cutting accuracy.
Stepless Speed Control: Both spindle and feed systems offer infinitely variable speed adjustment, ensuring precise machining for a wide range of bore sizes and materials.
Strong Customization Capability: Adaptable boring bar lengths and operating strokes are available to suit job-specific demands, including large, offset, or clustered hole structures on-site.
Overview
The Line Boring Machine Portable serves as a professional solution for after-weld hole corrections on heavy machinery. It's suitable for rotary joints, shaft sleeves, and articulation point re-machining.
