Product Introduction
Our line boring welding machine with unitized-based design manufactured by JDA machine tools enables clients to restore bore alignment and rebuild original size onsite, the unitized-based design allows all boring and welding works to be performed quickly.
With a rigid boring bar combined with a precise gearbox, delivering stable cutting performance, It will be a huge boost to to ensure continuous machining precision and surface finish.
Designed for working within confined locations, It will have greater adaptability for the bores in different locations. Save more time, reduce expensive transportation costs and minimize costly downtime losses.
Perfect for boring and welding repair worn bearing bores, pin holes, and pivot points, It will be a huge boost to extend the service life of expensive structural components and reduce replacement and downtime costs.
