Boring and Welding Machine,Our company, combining with the actual needs of field processing and continuous improvement in equipment structure, has developed the latest portable boring machine - currently the best engineering maintenance equipment. This innovative system, when paired with an automatic bore welding machine, creates a complete onsite repair solution. Equipment operation requires only one person to complete, as the design concept prioritizes field processing practicality, significantly reducing workers' actual workload and giving maintenance staff greater peace of mind.

The main application scope includes: processing various rotary holes, articulated holes, and shaft pin holes on engineering machinery structures after welding with an automatic bore welding machine, or reaming for adding hole sleeves; repairing and processing concentric holes in excavators, loaders, presses, cranes, etc. The system enables multiple side-by-side holes or multi-hole positional processing in one setup, ensuring coaxiality of multiple holes - a process greatly enhanced when combined with an automatic bore welding machine for pre-repair surface preparation.
As revolutionary equipment in modern industrial maintenance, portable boring machines (especially when integrated with automatic Boring and Welding Machine ) demonstrate core advantages in these aspects: Their combined capabilities allow for complete onsite repairs from welding deposition to precision boring, eliminating the need for equipment disassembly. The automatic bore welding machine first rebuilds worn surfaces, while the portable boring machine then achieves final precision dimensions, creating a seamless repair workflow that maintains original equipment tolerances.

Advantages of Boring and Welding Machines:
1. On-site processing capacity (the most prominent advantage)
-Realization of the "equipment does not move, the machine tool to move" concept of maintenance
-Eliminate the cost of dismantling and transportation of large equipment
-Especially suitable for nuclear power, wind power and other non-movable equipment maintenance
-Typical application case: on-site boring repair of 650-ton hydraulic turbine in a hydropower station, saving 2.8 million yuan in lifting costs.
2.Efficient operation system
-Quick installation
-Modularized design
-Adaptive cutting system automatically optimizes feed parameters
-Comparative data: shorten the working period by more than 70% compared with the traditional method
3.Economic advantages
-Maintenance cost is only 20-30% of new part replacement
-Typical payback time <6 months
-A petrochemical company saves more than 5 million RMB in annual maintenance cost.
4. Intelligent features
-Equipped with Industrial Internet of Things system
-Real-time monitoring of cutting force and vibration data
-Cloud storage of machining parameter files
-Support AR remote technical guidance
6.Extended functionality
-Optional auto bore welder module
-Integrated online measuring system
-Compatible with all types of materials (cast iron/alloy steel/composite materials)

FAQ
Q: What large equipment can a boring machine be used to repair on-site?
A: Mainly repairs the worn-out shaft holes, pin holes, and hinge holes of various construction machinery caused by long-term heavy-duty work.
Q: When would you use a boring machine?
A: Mainly used for machining or repairing holes on large equipment that can't be moved. For example: when you need to fix worn holes on site on large equipment, when you need to machine high-precision holes, or when you need to perform multiple machining functions.
Q: How precise can a boring machine be?
A: The machining accuracy of a boring machine doesn't have a single value; it mainly depends on the type of equipment (stationary vs. portable), the machining stage (rough boring vs. finish boring), and the material of the workpiece.
Q: Can a boring machine fix the coaxiality of multiple holes?
A: Yes, a boring machine can definitely fix the concentricity of multiple holes. It can treat several work holes that need to stay concentric as a single unit for machining, which ensures their concentricity precisely.
Q: Can a boring machine be used to repair holes in ship equipment?
A: Yes, boring machines can totally be used for repairing holes in ship equipment.
Q: How do we make sure our product is good quality?
A: Before mass production, we first run tests on pre-production samples; before shipping, we make sure the machine is working properly through a phone video call to complete the final inspection. Only then do we pack and ship it.
Q: How long is your warranty?
A: All machines from Wellnit come with a 12-month warranty, and the motors are covered for 3 months, starting from the delivery date. We offer 24-hour tech support, and you can reach us on WhatsApp (+86 18058880099).
