Product Description

CNC Portable Line Boring and Welding Machine for Repairing Excavator

Introduction
Automatic 2 in 1 portable line boring and welding machine is specially designed for on-site construction. It is small in size, light in weight, good at both boring and welding. It is not required for environment and space, and is easy to carry.
It is widely used in the repair of round holes such as pin holes and bearing holes of large-scale equipment and engineering machinery. It is an indispensable tool for industrial and mining enterprises and on-site maintenance.

Features
1/ Main Driving Unit
This series adopts the brush motor driven with the feature of lower speed and higher torque. The gear unit of reduction equipped with machine ensures the more powerful cutting.
2/ This new type of 2 in 1 borer and welder solves the problem of distortion of boring bar and vibration during cutting process which are caused by the longer cantilever. 
Also ensure there is no vibration during the process of axial moving and cutting process.
3/ Feeding and spindle rotation adopts stepless speed adjustment, the travel of feeding can be set according to actual requirement. The machine will stop automatically after reaching the limit stop.
4/ The tool post can be fixed at any location within effective travel.
5/ Just one equipment solves both boring and welding processing.
6/ Separate electric cabinet equipped with the controller, convenient for remote operation, convenient and safe.
7/ This machine can be equipped with end face milling attachment as request.
