Portable boring machines are mainly used for processing large diameter mud cutter head tool holder holes (in-factory, on-site, remanufacturing), cantilever tunneling machine frames, support frame processing, left and right support shoes, main beams, shields and other parts rework processing. It is required to be able to adapt to the diameter of φ100~φ800 hole processing function, can meet the horizontal, vertical direction and different angle clamping processing, the advantage is that it is portable and does not need to move the workpiece.
Dongguan portable tools aimed at produce high quality of on site machine tools, expecially the portable line boring machines with reliability and flexibility to hand tough line boring jobs enen in tight and limited spaces.
And our on site line boring machines could work in tough environment with different mounting ways, handling machining operations with horizontally and vertically or overhead, no extra lifting equipment or extra hands needed.
We manufacture the light duty and heavy duty in situ line boring machine with efficient and precise equipment with high precision parts from Japan and Germany. Our 5 axis CNC milling machine is also from these developed countries.
In situ line boring machines tailored to the refinery, oil, and gas industries. Portable line boring machine covers a lot of industries, including mining, heavyequipment, contrustionequpment, oil and gas , shipyard.
Our line boring machine allows us to repair booms and buckets at the highest precision for earthmoving and mining equipment. Combined with our expert welding services, we can repair and remanufacture booms and buckets, even when the holes are damaged or warped from regular use.

Portable in line boring machine gets it’s own concentricity, it depends on the adjustment of supporting arm, the skilled operator can control it well.
Here are some frequency questions below:
1. Boring bar straightness: 0.06mm/meter
2.Boring bar roundness: 0.03mm/diameter
3.Boring roundness: 0.05mm/meter
4.Boring taper: 0.1mm/meter
5.Flatness(of facing head) End milling flatness: 0.05mm
6.Surface roughness Finish RA: Ra1.6~Ra3.2
Main structural features of portable boring machine
The portable boring machine is mainly composed of boring bar, boring tool holder, feed screw, feed box, spindle box, support plate and feed motor, with a maximum size of φ950*2000 and a weight of ≤400kg.
The main parts of the boring machine are made of high-quality alloy steel, which is heat-treated to ensure accuracy and strength. The strength, rigidity and processing accuracy of the boring bar must meet the processing requirements.
Feeding method: Z-axis feeding can realize automatic and manual feeding, and the feed amount is infinitely adjustable.
The transmission screw has high transmission accuracy, accurate positioning, and a smooth transmission process.
The servo motor is used as the power, with stepless speed regulation, and can be controlled in forward, reverse and stop.
The tool holder is easy to install and disassemble, and standard tools (replaceable blades) are used. The boring tool is quick to adjust and the precision boring adjustment is high.
The equipment lifting points are set reasonably. The tool holder hole processing requires the use of machined inner holes and end faces for quick positioning. The inner hole three-point support is used for self-centering, the tool holder hole end face is positioned, and the end face threaded holes are used for installation and fixation. Quick installation and disassembly can be achieved, and horizontal, vertical and different angle installations can be met.
