Product Introduction
Our vertical portable boring and welding machine is a professional 2-in-1 industrial equipment designed to solve on-site repair and processing challenges for large machinery and equipment. Unlike traditional bulky boring or welding machines that require fixed workshop spaces, this vertical portable model combines high-precision boring and efficient welding functions in one compact, movable unit—making it ideal for on-site operations where mobility and space-saving are critical.

Product Usage Scenarios
This portable mobile boring machine pays for itself fast. Here's what our customers actually use it for every single day:
Construction Machinery
Excavator boom, stick, and bucket pin holes (the #1 repair job by a mile)
Loader and backhoe hinge points and bucket pins
Bulldozer blade pivots and track frame bores
Crane outrigger pads and main pivot joints
Forklift mast bearings and wheel hubs
Real story: A guy in Ghana bought one of these machines last year. Before that, he was paying a mobile repair company $1,200 per pin hole repair. Now he does them himself for $50 in materials. He paid off the machine in 4 jobs. Now he's doing repairs for other companies in his area and making an extra $8,000 a month.
Customer Feedback
These are real messages from real customers. We didn't edit them. We just copied them straight from our WhatsApp and email.
"I bought this cnc linear boring and boring welding machine 18 months ago, and it's the best investment I've ever made for my repair business. Before, I was turning down 2-3 jobs a month because I couldn't transport the big parts. Now I go to the customer's site and finish the job in a day. The machine is built like a tank – we've used it almost every day and the only thing we've replaced is cutting inserts. When I had a question about the welding settings at 10pm my time, I sent them a WhatsApp and they replied in 15 minutes with a video showing me exactly what to do. 10/10 would buy again."

"We run a mining operation in Western Australia, and downtime costs us $2,000 an hour. This machine has saved us hundreds of thousands of dollars. We used to fly technicians in from Perth to repair our haul trucks, which took a week minimum. Now our own maintenance team can do the repairs on-site in a day. The build quality is outstanding, and the after-sales support is actually reliable – something you don't always get from Chinese suppliers. We just ordered our third machine for our new mine site."
— David Wilson, Maintenance Manager, Gold Fields Australia
Service Commitment
We stand behind every machine we build. Our service isn't just fine print – it's a promise we keep.
1-Year Full Warranty
All parts are covered for 1 year against manufacturing defects. If anything breaks within the first year, we'll ship you a replacement part for free – no questions asked. We even cover the shipping cost. The only things not covered are normal wear items like cutting inserts and welding nozzles.
Lifetime Technical Support
We have 8 engineers on call 24/7 to help you with any problems. You can call us, email us, or send us a WhatsApp message anytime. We'll usually reply within 15 minutes during working hours, and within 2 hours outside working hours. If we can't solve the problem over the phone, we'll send you a step-by-step video showing you exactly what to do.
Fast Spare Parts Delivery
We keep a full inventory of all spare parts in our warehouse. Most common parts can be shipped within 24 hours. For urgent orders, we can send them via DHL/FedEx express so you get them in 3-5 days. After the warranty expires, we sell spare parts at factory cost – not 3x the price like some other brands.
