Line boring and internal welding machine

Product Introduction

 This line boring and internal welding machine It’s a field-tested, beat-up-and-still-works all-in-one system, purpose-built to fix worn, out-of-round, cracked, or damaged bores right where your equipment sits. It combines precision line boring and full internal overlay welding into one compact, modular unit, so you can complete weld buildup, rough boring, and finish boring in a single setup. No repositioning the workpiece, no realigning the machine 5 times a job, no risk of mismatched concentricity between your weld and final bore. It’s used every single day by mobile repair contractors, mining maintenance teams, construction yards, marine repair facilities, and farm service crews in 120+ countries. If you’ve got a bore that needs fixing, this machine will get the job done faster, cheaper, and with better precision than any workshop setup.

Product Usage Scenarios

This isn’t a machine that only works in a clean, climate-controlled workshop. It’s built for the real world, and it earns its keep in every corner of the heavy equipment industry. Here’s where our customers use it every single day:

1. Construction & Heavy Equipment Repair (Our #1 Use Case)

If you fix excavators, loaders, bulldozers, cranes, or road rollers, you know exactly how painful a worn pin bore can be. Before this portable line boring and welding machine machine, your options were: tear the entire boom or assembly off, haul it to a workshop, wait 3-5 days for repairs, and pay a fortune in labor and towing. Now, you can fix it right on the job site. We’ve got customers repairing bucket ears, hinge points, outrigger bores, and hydraulic cylinder mounts in 4-6 hours, with zero disassembly of the main machine. It fits in the tight spaces inside boom arms that big, bulky workshop machines can’t touch.

2. Marine & Shipyard Repair

Ships and offshore platforms have tight, hard-to-reach spaces that most boring machines can’t access. Our modular design lets you break the machine down into lightweight pieces, carry it into engine rooms, hull compartments, and dry dock spaces, and assemble it right where you need it. It’s widely used to repair rudder stock bores, winch drum bores, engine mounts, and hydraulic system components, with precision that meets strict marine industry standards. We’ve got shipyards in Dubai, Singapore, and Rotterdam that run multiple units full-time.

3. Agricultural Machinery Repair

For farm service crews and mobile ag repair contractors, downtime during planting or harvest season is catastrophic. This boring and welding machine tool machine fits perfectly in the back of a service pickup, so you can drive right to the farm field and fix worn pivot points, axle bores, and hydraulic component bores on tractors, harvesters, balers, and planters right where the machine sits. No towing the equipment back to the shop, no waiting for parts, no lost crop yield from idle equipment. We’ve got 1-man repair contractors in Brazil, the US Midwest, and Eastern Europe that use this machine every single day.

Service Commitment

We stand behind every line boring and welding machine machine we build. This isn’t some fine-print warranty that disappears when you need it most. This is our real, no-BS promise to you, for as long as you own the machine.

1. Straightforward Warranty Coverage

12-month full warranty on the entire machine, covering all manufacturing defects and quality issues.

24-month extended warranty on the core spindle unit and main motor.

During the warranty period, if any part breaks due to a manufacturing defect (not accidental damage, misuse, or lack of maintenance), we’ll send you a replacement part for free, cover 100% of the shipping cost, and walk you through the installation step by step. No hoops to jump through, no fine print.

Even after the warranty expires, we’ll sell you any spare part you need at our direct cost price. No markup, no inflated pricing, ever.

2. 24/7 Global Technical Support

3. Full Customization & OEM Support

We offer full OEM and ODM customization services for global distributors and brand partners, including custom model design, voltage customization, branding, logo printing, and custom packaging. Our R&D team can also design and build fully custom line boring and welding machines to match your unique repair requirements and job site conditions.

FAQ

These are the real questions we get asked every single day by new customers, not generic AI-generated fluff. If you have a question that’s not listed here, just send us a message, and we’ll get back to you right away.

Q: Can this machine really do internal welding and line boring in one setup?

A: Yes, 100%. That’s the whole point of the design. You can complete weld buildup, rough boring, and finish boring all in a single setup, with no need to reposition the workpiece or the machine. This eliminates alignment errors, ensures perfect concentricity between the weld and the final bore, and cuts your total repair time by up to 60%.

Q: What voltage options do you offer? Can you customize the voltage for my country?

A: Our standard models support 380V 3Phase and 220V Single Phase, which works in most countries around the world. We also offer full voltage customization for free, including 440V, 415V, 110V, and any other regional voltage standard. Just tell us your local voltage when you place your order, and we’ll build the machine to match.

Q: I’ve never used a line boring machine before. Will you teach me how to use it?

A: Absolutely. Every machine comes with a full set of step-by-step video tutorials and a detailed English manual. We also offer free one-on-one online video training, where our engineer will walk you through every step of setup, operation, and maintenance. Even with no prior experience, you’ll be able to run full repairs after a 1-2 hour training session.
