Product Introduction
Our CNC Linear Boring And Boring Welding Machine is a 2-in-1 portable CNC tool that does two jobs in one: precise linear boring and automatic bore welding. No fancy terms here – it’s just a tough, reliable tool made for on-site maintenance. If you’re sick of taking apart heavy machinery just to fix worn pin holes, bearing bores, or hinge holes, this is the machine you need. You can repair those damaged parts right where the equipment is, no disassembly required – saves you tons of time and frustration.It runs on a reliable CNC control system, so you get consistent machining accuracy every single time – no more hit-or-miss results. Switching between boring and welding modes is a breeze, even if you’re not a CNC expert. We built it for teams that work on excavators, loaders, bulldozers, cranes, mining gear, and agricultural equipment. Here’s the bottom line: it cuts down equipment downtime, saves you money on labor, and makes repairs more dependable. Whether you’re a small repair shop or a big construction crew, this machine works for you, no matter where you are in the world.
Product Parameters
Boring Diameter | Φ45–Φ300 mm – covers almost all the common hole sizes you’ll find on heavy machinery |
Welding Diameter | Φ45–Φ300 mm – matches the boring range, so you can weld and bore seamlessly in one job |
Boring Bar Size | Φ50×1600 mm – strong enough to handle heavy-duty cutting, won’t bend or break under pressure |
Spindle Speed | 50–300 rpm – stepless adjustment, so you can tweak it to work with different materials easily |
Effective Stroke | 300 mm – if you need a longer stroke, just let us know – we can adjust it for you |
Control System | CNC full-automatic control – the interface is simple, no complicated programming needed |
Power Supply | AC 220V/50Hz – we can change this to 110V or 380V to match your region’s power supply |
Motor Power | 3.1 kW servo motor – strong, energy-efficient, and built to last for years of heavy use |
Working Accuracy | Roundness ≤ 0.02 mm – meets all industrial repair standards, no extra finishing needed |
Surface Roughness | Ra ≤ 3.2 – the finish is smooth, so you don’t have to spend extra time polishing |
Net Weight | 165 kg – light enough to move around on-site, but heavy enough to stay stable while working |
Package Size | 1700×480×450 mm – fits perfectly in standard shipping containers, no extra fees |
Product Details
CNC Intelligent Control Panel
The digital display is clear and easy to read – no squinting at tiny text or confusing menus. You can set the feeding length ahead of time, program it to stop automatically when it’s done, and even use the one-key function for the jobs you do most often. This cuts down on mistakes from manual operation, and you can leave it running unattended for simple tasks – perfect for busy repair sites where every minute counts.
High-Precision Boring Spindle
We use heavy-duty linear guide rails and a tough, rigid structure, so it stays steady even when you’re doing heavy cutting. It barely vibrates, which means cleaner cuts and less wear on the machine. It holds up great in tough job-site conditions – dust, debris, and constant use won’t wear it down or break it.
Modular Portable Design
The parts are detachable and lightweight, so you can load them into a truck or van without any hassle. No need for a crane or heavy equipment to move it around. A single operator can put it together and get it set up in 15 to 20 minutes – no extra help needed, which saves you time and labor costs.
Product Usage Scenarios
This CNC linear boring and welding machine is made for real-world repair work – here’s where it really shines:
•Excavator arm, bucket, and boom pin hole repair – fix worn holes fast, no need to take the excavator apart
•Loader, bulldozer, and crane bearing bore restoration – get heavy machinery back up and running quickly
•Mining machinery & heavy-duty equipment hole maintenance – handles tough, high-wear parts that other machines can’t
•Agricultural machinery shaft hole and hinge position machining – perfect for tractors, harvesters, and other farm equipment
•Construction machinery repair shops & on-site field service – saves time on transporting equipment to and from the shop
•Marine and industrial equipment concentric hole processing – works in tight spaces on ships or in factories
Service Commitment
We stand behind our products – here’s what you can expect from us after you buy:
Warranty: 12-month free warranty on the entire machine. If any part breaks down during this period (and it’s not from human error), we’ll send you a replacement part for free – no extra charges, no hidden fees.

After-Sales Response: We reply to technical questions within 2 hours – no waiting around for days. For most issues, we can solve them online within 24 hours. If you need on-site support, we can arrange that too (additional fees may apply, depending on your location).
Spare Parts: We supply original spare parts at factory price for life. You won’t have to worry about finding compatible parts – we have everything you need in stock, and we ship them quickly worldwide.
Customization: Every job site is different. We can customize the boring diameter, stroke, voltage (110V/220V/380V), and even add your logo – just tell us what you need, and we’ll make it happen.
FAQ
Q1: Is this machine portable enough for on-site use?
A1: Absolutely – no question about it. It’s built with a modular, detachable design, so all parts are lightweight enough to carry by hand or load into a van. You don’t need heavy equipment to move it, and it’s easy to set up on-site. No need to take apart the heavy machinery you’re repairing – just bring the machine to the equipment.
Q2: Do I need professional skills to operate it?
A2: Nope. The CNC panel is simple and straightforward – even beginners can learn it in no time. We provide a clear English manual and operation video, and our team is here to help if you get stuck. You don’t have to be a CNC expert to use this machine.
