The Normaco NLB40 Line Boring Machine is a portable line boring tool designed for precision machining of in-line bores. Equipped with a high-performance drive unit, it offers the flexibility of being powered by either an electric motor or a pneumatic motor, making it ideal for a range of industrial applications.
This line boring machine features a manual feed through a user-friendly hand wheel, offering precise control during in-place machining operations. Centering is quick and efficient using centering cones, which ensure accurate alignment with minimal deviation.
The NLB40 Line Boring Machine is used in industries such as heavy equipment repair, construction, mining, and shipbuilding, where on-site machining is essential. Typical applications include repairing worn bores, restoring pivot points, and fixing hinge holes on large machinery like earth-moving equipment and industrial turbines. This machine excels in machining operations that require durability and precision.
Easily customizable, the NLB40 can be configured to meet specific job requirements by selecting from a variety of components, making it a flexible solution for different line boring applications.
Basic kit includes:
- Drive unit with electric drive 230v
- Boring bar 1.6m
- Centering device sets (2pcs)
- Bearing mounts (2pcs)
- Crate
If you would like to customize the machine by changing for example the motor type, length of boring bar, number of mounting brackets, etc, Please contact us by email at [email protected]
