Line Boring Machine Tool
Broad machinery compatibility：Suits excavators and various heavy duty engineering equipment pin hole maintenance
Stable machining precision：Delivers steady spindle rotation to guarantee uniform hole size after reprocessing
On‑site maintenance support：Works directly on machinery,avoids heavy workpiece disassembly and reduces downtime
Portable 2‑in‑1 structure：Integrates boring and overlay welding to complete hole repair without multiple sets of equipment
Product Introduction
The Line Boring Machine Tool is a reliable on-site boring and welding solution built for heavy equipment field repair. It works as a portable alternative to fixed workshop Cylinder Boring And Honing Machine units, solving the long-standing problem that traditional Boring Machines Cylinder can only operate inside factory premises.
As a practical Multi Boring Machine, it completes precision boring and overlay welding directly on intact equipment frames, with no need to tear down heavy components and ship them to distant machine shops. This cuts repair downtime from 3-5 days to just several hours, and slashes total repair costs by up to 70% for most jobs. It runs on standard 220V mains power, sets up quickly, and fits both deep and shallow bore repair tasks across multiple industries.

Product Details
Stable drive motor
The 2.6KW heavy-duty motor delivers steady rotating power for continuous boring work, holding consistent speed even in rough outdoor site conditions. It matches the machining accuracy of standard Boring Machines Cylinder for most common repair jobs.
Dual bar set configuration
It comes with two boring bars and two welding rods of different lengths, fitting both deep cylinder bores and shallow frame pin holes. As a flexible Multi Boring Machine, it covers nearly all regular bore sizes on construction and mining equipment with no extra accessories needed.
Compact portable structure
Unlike bulky fixed Cylinder Boring And Honing Machine setups, this unit adopts a lightweight split design. Two workers can carry and assemble it fast on site, and it fits in the back of most service trucks without a dedicated trailer.
2-in-1 boring & welding function
It integrates precision boring and build-up welding in one system. Technicians can finish weld surfacing and final boring in a single setup, no need to reposition workpieces and risk alignment deviation.
Universal power design
It works with regular 220V/50HZ household mains, no industrial three-phase power required. This makes it usable for remote mine sites, rural farm workshops and outdoor construction sites with limited power access.
Product Usage Scenarios
This Line Boring Machine Tool works as a universal repair tool across all heavy equipment sectors:
Construction machinery repair: Fix worn pin holes on excavator booms, loader bucket hinges and bulldozer frames on site, as a portable replacement for workshop Boring Machines Cylinder.
Mining equipment maintenance: Repair haul truck suspension bores and drill rig connection points directly at mine sites. Its rugged build adapts to dusty high-load environments, matching the repair effect of dedicated Cylinder Boring And Honing Machine units.
Agricultural machinery service: Refurbish tractor axle housing bores and harvester frame pin holes during busy planting and harvest seasons, cutting downtime to keep farm operations on schedule.
Small workshop processing: As a compact Multi Boring Machine, it handles small-batch custom boring jobs for mechanical spare parts, saving small repair shops the cost of investing in large fixed equipment.
Packaging and Delivery
All parts of the Line Boring Machine Tool are packed in thick export-grade plywood cases with shockproof foam filling inside, to prevent collision damage during long-distance sea or land transport. Small fittings like bolts and welding tips are sealed in labeled plastic bags to avoid loss.
We support common international trade terms including FOB, CIF and EXW. In-stock units ship within 3-7 working days after payment confirmation. Bulk orders are loaded in full containers, and small trial orders can be shipped via LCL sea freight or international express as requested.
Factory Profile
We have specialized in manufacturing portable on-site boring and welding equipment for many years, with independent production workshops and dedicated product testing areas. Every Line Boring Machine Tool goes through full running tests and precision inspection before packing to ensure stable on-site performance.
Our factory welcomes global buyers and distributors to schedule on-site visits and machine trials at any time. OEM customization for specific specifications is available for bulk orders to fit different regional market demands.
Customer Feedback
Client from Kenya (Local Construction Repair Shop): “We bought this unit to replace our old fixed Cylinder Boring And Honing Machine last year. We now do most repairs on site, finish 2 to 3 more jobs per week, and save a lot on transport costs. It works as accurately as our old shop machine for most bore sizes.”
Client from Indonesia (Mining Service Team): “This Multi Boring Machine works great in our dusty mine sites. It’s easy to move between different haul trucks, and our technicians picked up operation in half a day. It’s way more flexible than the heavy Boring Machines Cylinder we used before.”
