Product Details
Every Boring and welding integrated machine is built tough. High-strength aluminum body is light but solid—won’t dent or crack even if you drop it on concrete. Split design means two guys can carry it easily into tight spots: engine bays, undercarriages, ship engine rooms—places big stationary machines can never reach.
Precision-ground hardened steel spindle runs totally vibration-free at top speed. You get factory-perfect bores every single time. No wobbly holes, no rework. The auto weld system lays clean, no-porosity beads without constant tweaking—cuts operator tiredness and saves hours on every job. Control panel is dead simple: big, clear buttons that work even with oily gloves on. The optional CNC module saves your go-to jobs—just press one button and walk away.
This Mobile line boring machine comes with all the standard bars and rods you need for 90% of common repairs. Uses regular 0.8-1.2mm welding wire you can buy anywhere in the world. No fancy proprietary parts, no hidden costs.、
