A partial machine refurbishment & full CNC retrofit of a TBT model B3B 5000 NC Deep Hole Drilling Machine.
Mechanically, the machine was in quite good condition, therefore, the mechanical refurbishment work was limited to renewal of the Boring Spindle Drive System; this included replacement of the entire Worm Rack (14,000mm) and the two phosphor bronze anti-backlash Worms.
Electrically, the machine was retrofitted with a new Siemens 840D Control, new Digital Spindle Drives to both the Workhead & Boring Spindle, new Digital Axis Servo Drives, a new electrical cabinet complete with all new control gear and a complete machine re-wire.
