Product Description
How Our Portable Line Borer Solves On-site Machining Challenges.
The Powerful, Proven and Reliable On-Site Boring & Facing Solution for Cement Plant Equipment, Large Structures and Heavy Equipment.
Our BB35600 portable line borer is purpose-designed for on-site machining and repair of cement plant equipment, large structures and heavy equipment. It provides a flexible and cost-effective solution for fine machining, restoring worn, misaligned or deformed bores without dismantling large components.
With its a wide boring range from 35 mm to 600 mm, the portable line boring machine covers most common bore repair requirements found in cement production facilities, including crushers, rotary kilns, mills, conveyors, and heavy support structures.
The available power options have electric, servo motor or hydraulic, the portable line boring tools adapt easily to different site conditions and power availability. The optional facing attachment can expand its capabilities, which allow both line boring and face machining to be completed in a single on-site set-up.
Our portable line borer significantly reduces downtime, maintenance cost, and production losses in cement plants by avoiding the need of workshop transport.

FAQ
Q: What bore diameter range can a line bore machine handle?
A: It depends on the specific model. Portable line boring machines typically cover small to large bore ranges with different bar sizes and accessories for various repair requirements.
Q: Is portable line boring equipment suitable for repairing oval or elongated holes?
A: Absolutely. Line boring tools is one of the most effective methods for restoring oval, worn, or deformed bores. The holes are restored to the correct roundness and size for proper pin or bushing installation.
Q: Can the alignment correction of multiple bores be machined in one set-up?
A: Yes. One of the key advantages of portable boring machine is the ability to machine multiple coaxial holes in a single alignment for ensuring perfect bore alignment and reducing assembly issues.
Q: What power options are available for inline boring machine?
A: Portable line boring machines are commonly available with electric or hydraulic drive options for allowing flexibility based on job-sites' power availability and working conditions.
