PIPLB110 Line Boring Machine

The PIINC PIPLB110 Portable Line Boring Machine is a modular, heavy-duty machining system designed for large-diameter internal bore machining and on-site repair of oversized components. With a 110 mm boring bar diameter and a boring diameter range of Ø220–1,066 mm, the PIPLB110 is suitable for demanding machining applications involving large-scale marine structures, ship mounting holes, and shaft bores.

Its modular design provides flexibility in machine installation and component positioning, making it suitable for challenging work environments where transporting large components to a conventional machine shop may be impractical. The rotational drive unit can be mounted at different positions along the boring bar, while the automatic feed unit can be installed at either end to accommodate different machining configurations.

Equipped with a high-strength alloy structural steel boring bar, an adjustable boring head, and servo or hydraulic drive options, the PIINC PIPLB110 is designed to support demanding field machining and industrial maintenance operations.

Key Features and Benefits

1. Large-Diameter Boring Capacity

The PIPLB110 is designed for large-scale boring applications, with a machining diameter range of Ø220–1,066 mm. Its 110 mm boring bar provides the foundation for a system intended to handle substantial machining requirements in marine and industrial applications.

This large-diameter capability makes the machine suitable for on-site machining of ship mounting holes, shaft bores, and other large internal bores, subject to the specific workpiece and setup requirements.

2. Modular Design and Flexible Installation

The modular construction allows the machine to be configured for different workpiece geometries and installation conditions.

• The rotational drive unit can be mounted at different positions along the boring bar.

• The automatic feed unit can be installed at either end of the boring bar.

• Quick-set adjustable clamping jaws facilitate setup adjustments.

• Multiple mounting kit configurations are available to suit different machining requirements.

This flexible arrangement helps accommodate complex machining setups in locations where access and installation space may be limited.

3. High-Strength Alloy Steel Boring Bar

The PIPLB110 uses a boring bar manufactured from high-quality alloy structural steel, designed to provide high strength and rigidity for large-scale machining applications.

The boring bar can reach lengths of up to 10 metres, supporting extended-reach machining of large components. Customized boring bar lengths are also available to meet specific project requirements.

4. Adjustable Boring Head for Machining Accuracy

The PIPLB110 features a separately designed boring head with a freely adjustable nut gap. This design allows adjustment of the boring head assembly and supports accurate setup for machining operations.

The separate boring head design provides an additional level of flexibility when configuring the machine for different boring applications.

5. Servo or Hydraulic Drive Options

The PIPLB110 is available with either a servo motor or a hydraulic power system, allowing users to select a drive configuration suited to their application requirements.

The drive system supports stepless speed regulation within a specified range of 5–30 RPM, with constant-torque operation as described for the machine.

This combination of selectable drive systems and adjustable rotational speed provides flexibility for different large-diameter machining tasks.

6. Versatile Facing, Groove, and Bevel Machining

The PIPLB110 incorporates several features that expand its machining capabilities beyond basic line boring.

• Quick-Set Adjustable Clamping Jaws: Support convenient setup and positioning.

• Swivel Toolpost: Enables groove and bevel machining.

• Continuous Groove Geared Feed: Provides geared feed functions for facing and boring operations.

• Flexible Drive Positioning: Allows the rotational drive and automatic feed units to be arranged to suit the machining setup.

These features make the PIPLB110 a versatile option for specialized on-site machining and industrial maintenance applications.

7. Multiple Mounting Kit Options

Three mounting configurations are available:

• Three-Arm Mounting Kit

• Four-Arm Mounting Kit

• ID Mounting Kit

These options provide flexibility when installing the machine on different workpieces and adapting the setup to specific boring requirements.
