Product Description
Our horizontal line boring is a perfect line boring solution designed for accurate on-site bore repair in limited working spaces. It is excellent for machining applications of small to medium bore where traditional shop machining is neither practical nor costly.
By performing line boring directly on the equipment, this worn, elongated or misaligned bores can be restored without dismantling large components, significantly reducing downtime and repair cost. It can perform working with limited setup space. This feature makes it ideal for field service, maintenance teams, and mobile repair operations.
Installation Direction
The line boring machine is usually installed in horizontal direction. But it is also capable of performing bore machining in other directions, such as vertical, tilted direction or other angle direction.
Designed for On-Site Repair
The horizontal line boring is built to operate reliably in real job-site conditions. Its lightweight and modular design allows to do easy transportation and fast installation, even in confined areas such as excavator arms, cab, buckets, linkages, and equipment frames.
The system can be mounted directly on the work piece by weld-on or bolt-on for ensuring precise alignment and stable machining performance during on-site operations.
Compact and Rigid Structure
Although it is compact size, the machine has a rigid mechanical structure that keeps consistent cutting accuracy. High rigid components ensure smooth boring operations, proper concentricity, accurate bore alignment correction, and correct pin and bushing fit after repair.
Its perfect combination of portability and rigidity makes it a practical solution for frequent on-site repair tasks.
Easy Setup and Operation
The horizontal line bore machine is designed with ease of use in mind. Simple alignment methods, intuitive controls, straightforward operate system and convenient tool changing operation reduce setup time and allow operators to complete repairs efficiently.
It is suitable for both experienced machinists and new onsite machining service teams to portable line boring. So it is an excellent entry-level solution for expanding on-site machining capabilities.
