TDG50 Line Boring Machine

TDG50 Portable Line Boring Machine – Compact, Powerful On-Site Machining Solution

The PIINC TDG50 Portable Line Boring Machine is a lightweight, compact, and versatile on-site machining solution designed for precision bore repair and machining in confined spaces and challenging working environments. Drawing on more than 15 years of on-site engineering service experience, PIINC combines practical field machining expertise with advanced design concepts to deliver a portable line boring system for industrial maintenance and heavy equipment repair.

With a standard boring diameter range of 55–300 mm and an optional configuration starting from 38 mm, the TDG50 is designed to handle a wide variety of boring applications. Its compact construction, integrated rotation drive and automatic feed unit, and flexible mounting system make it suitable for field machining where transporting large equipment or dismantling machinery is difficult.

Key Features and Benefits

1. Lightweight and Compact Design

The TDG50 features a compact structure that makes it suitable for confined workspaces, restricted-access areas, and elevated working positions. Its portable design helps operators perform on-site machining and repair in locations where conventional machining equipment may be difficult to install or operate.

2. Integrated Rotation Drive and Automatic Feed

The integrated gearbox combines the rotational drive and automatic feed functions into a compact unit weighing only 9.5 kg. This design simplifies equipment handling and installation while supporting efficient on-site boring operations.

The feed system provides stepless adjustment within the specified range of 0–0.5 mm, with forward and reverse operation to accommodate different machining requirements.

3. Quick and Flexible Setup

The TDG50 is equipped with a three-leg mounting kit that can be adjusted to different angles to accommodate various boring configurations. Its modular design supports flexible installation in challenging working environments, helping reduce setup complexity and improve job-site efficiency.

High-quality cast-iron setup cones and spherical bearing mounts are also described as part of the setup system. Typical setup time for an experienced operator can be 30 minutes or less, depending on the application and installation conditions.

4. Powerful Drive Performance

The standard drive power unit is an 1800 W electric motor. The specially designed rotational drive incorporates a 4:1 worm gear reduction to provide increased torque across the operating speed range.

The machine delivers over 100 ft-lb (135 N·m) of torque at the boring bar, supporting demanding on-site machining applications. The maximum cutting depth can reach 6 mm, depending on machining conditions and the application.

The reversible electric motor supports forward and reverse operation, while the two-bolt motor change-out design allows convenient motor replacement.

5. Integrated Measuring Tools

The TDG50 comes equipped with a bore cutter measuring tool and a diameter measuring ruler. These tools help operators measure cutting tool dimensions and boring diameters during setup and machining, supporting accurate adjustment and dimensional control during field repair work.

6. Flexible Configuration and Optional Accessories

The TDG50 offers flexible configuration options to accommodate different machining requirements.

• Small Bore Kit: An optional Ø38 mm boring bar extends the boring diameter capability to the range of Ø38–300 mm.

• Facing Head: An optional facing head supports face machining of pipes and flanges.

• Facing and Grooving Accessories: Optional tooling expands the machine's capabilities for additional on-site machining operations.

• Bore Welding System: An optional bore welder can be integrated with the line boring machine to support combined boring and welding repair operations.

• Multiple Boring Bar Lengths: Boring bars are available in lengths from 4 to 6 feet (1219.2–2000 mm), providing flexibility for different job requirements.

• Flexible Component Positioning: The through-bar design allows the rotational drive and feed unit to be mounted at different positions along the boring bar, including separately, to suit specific installation constraints.

The boring bars are manufactured using special materials and heat-treatment-related processing to achieve high hardness, as described by the manufacturer.

Applications of the TDG50 Portable Line Boring Machine

The PIINC TDG50 is suitable for on-site machining, bore restoration, and equipment maintenance across a range of industries. Its portable design makes it particularly useful for repairing machinery that is difficult, costly, or inconvenient to transport to a conventional machine shop.

Typical applications include:

• Construction Equipment Repair: Repairing worn bores in excavators, loaders, bulldozers, tractors, backhoes, and cranes.

• Heavy Equipment Maintenance: On-site machining of equipment mounting points, pivot bores, and other suitable components.

• Marine and Ship Repair: Performing field machining and repair on ships and marine equipment.

• Industrial Machinery Maintenance: Repairing bores in production machinery and industrial equipment.

• Pipe and Flange Machining: Performing facing operations with the appropriate optional accessories.

• Combined Boring and Welding Repair: Supporting integrated bore restoration workflows when configured with the optional bore welding system.

Why Choose the PIINC TDG50?

The PIINC TDG50 Portable Line Boring Machine combines portability, flexible installation, integrated drive and feed functions, and optional machining accessories in a compact field repair system.

For maintenance contractors, equipment repair shops, and industrial service providers, it offers a practical solution for machining directly at the job site. By bringing boring capabilities to the equipment rather than transporting the equipment to a workshop, the TDG50 can help simplify repair logistics and reduce the inconvenience associated with equipment disassembly and relocation.

Choose the PIINC TDG50 Portable Line Boring Machine for flexible on-site bore repair, efficient field machining, and versatile heavy equipment maintenance.
