High Precision & Low Cost: ±0.01mm boring accuracy, cuts 40% repair cost vs traditional workshop processing
Strong Adaptability: Portable boring machine fits narrow construction sites & mining areas in Africa & Southeast Asia
Durable & Rust-proof: Anti-corrosion metal body for line boring machine, adapts to tropical humid & dusty environments
Product Introduction
This small diameter line boring machine is a portable, heavy-duty machining tool built mainly for track bushing pressing, pin hole fixing and concentric boring work on construction machinery. It is made to handle on-site maintenance jobs for small and medium-sized engineering equipment, skipping the trouble of using large, fixed boring machines that are hard to move and won't fit in tight work spaces.Made with solid industrial-grade materials, this machine runs steadily with high boring precision, clamps fast and is simple to operate. It cuts down equipment downtime and cuts maintenance costs a lot. It works great for repairing track pins, bushings, shaft holes and hinge holes on excavators, loaders, bulldozers and other heavy equipment, making it a must-have tool for repair shops, job sites and equipment maintenance teams.

Product Details
The automatic portable line boring machine spindle is finely ground and balanced for smooth rotation, keeping consistent boring accuracy even during long hours of heavy use. It runs without wobble and leaves a smooth inner hole finish, which fits track bushings and pins perfectly for tight assembly.
We use hardened precision guide rails that are rigid and wear-resistant. The feeding stays smooth and steady at all times, and the rails won't deform easily, so the machine keeps its machining accuracy for years and lasts longer overall.
This machine has a compact, lightweight build that's easy to carry and move around. It fits well in narrow job site spaces, and you can set it right on the workpiece for on-site boring without having to move heavy equipment.
Packaging and Delivery
Each line boring machine machine is wrapped with waterproof and damp-proof film first, then padded with thick shockproof foam. It's packed in a sturdy export plywood crate reinforced with steel edges, to prevent bumps, crushing and moisture damage during long shipping. We make sure the machine arrives in perfect condition.
We offer global shipping by sea, air or land. Standard shipping marks and labels are attached to every crate. We work with reliable logistics partners to ensure on-time delivery. Full container loads are available for bulk orders, and LCL shipping is offered for small orders to cut down shipping costs.
