Bore Welder For Sale | DIG-DOG BWM-50P Bore Welding Machine
DIG-DOG BWM-50P Portable Boring and Welding Machine is a high-end equipment that integrates various function modes of welding hole, boring hole and end face processing at present, realizing the processing of cylinder hole in idle narrow position of engineering machinery, and further improving the processing capacity of the equipment. The original hole welding, boring processing functions need welding, boring two sets of equipment to complete, the new equipment integrated the two functions, only after the completion of the hole welding process reassembly can realize the boring function.
Machine the Revolving Holes, Articulated Holes, Shaft Pin Holes on Various Engineering Machinery Structures after Repair Welding, or Installing Hole Sleeves after Reaming. Repair and Processing Concentric Holes, One-time Positioning Processing of the Porous on Excavators, Loaders, Presses, Cranes, etc. to Ensure the Coaxiality of the Porous.

BWM-50P Equipment Characteristics
1. Main drive uses a 220V servo motor, it has the characteristics of low speed and high torque. The whole machine can achieve smooth cutting and superior performance, providing excellent rotational power for welding holes and boring holes.
2. The new boring and welding machine solves the boring bar bending and cutting vibration caused by the overlong cantilever of the previous equipment. The equipment has no vibration in its axial movement and cutting process.
3. Both feeding and processing can achieve stepless speed regulation, the feeding stroke can be set as needed, and processing can be automatically stopped after processing reaches the limit switch position.
4. The boring bar is made of high-strength alloy structural steel, which has the characteristics of high hardness, high precision, high toughness and good wear resistance.
5. Within the effective stroke, the tool holder can be fixed at any position of the boring bar.
6. The boring bar can be disassembled separately and is easy to install.
7. It realizes the processing of cylinder holes in empty and narrow positions on engineering machinery, further improving the equipment's processing capabilities.
8. In the past, the welding and boring processing functions required two sets of equipment: welding and boring. This new equipment combines the functions of the two. It only needs to be assembled after the welding process is completed to realize the boring function.
9. The motor controller is equipped with a dynamic delay braking program to avoid vibration when parking.
10. The control box is an independent control box and is equipped with a control handle to facilitate remote operation by workers, which is safe and convenient.
11. The equipment also has the extended function of boring end faces, which customers can choose according to their processing needs.

FAQ
What size of line boring machine should I choose?
There are many different sized line boring machines available.   No single machine can cover all of the above diameters accurately, so you’ll need to consider the type of jobs you will be carrying out.

What boring bar length should I specify?
There are many different bar lengths available, it is mostly depend on your job need.    One thing to remark: for small diameter boring bar, the longer the bar is, the bigger the risk of sagging is.

What are the lead times for line boring machine?
This varies depending upon size of machine and stock availability.  With line boring machines it pays to think ahead as it can be several weeks from receipt of payment before your machine arrives.       This is because each machine package is made to order from the many options available.

Can DIG-DOG supply a machine in my area?
Yes, Our portable boring machine export world-widely.

What maintenance is needed?
If looked after correctly, the line boring machine will provide years of trouble free use, delivering accurate and consistent results every time.       Simple cleaning, debris removal and oiling is mostly all that is needed.
