Fixed Bridge (twin moving table) type machine equipped with 1 (one) 18 HP 4-pole air-cooled router spindle, with grease lubricated ceramic bearings, a 10-Position Automatic Tool Changing System, with tool length touch probe. 1 (one) 2 HP, multiple spindle boring unit with 9 independently selectable spindles for vertical boring. The spindle motor is powered by an electronic AC inverter drive system with dynamic spindle braking. Full Torque is achieved at 9,000 RPM & Full HP is achieved at 12,000 RPM. The Automatic Tool Changer Carousel, Steel Tool Holder Clips, is mounted on the spindle carriage, next to the Router Spindle, for fast and efficient tool changes. X, Y, & V axes are constructed of massive, heavy duty welded steel construction with multiple reinforcements to increase strength & absorb vibration. Z-axis spindle carriage is a specially designed Meehanite casting for high strength and inherent vibration dampening characteristics with a pneumatic counterbalance system for smooth & accurate operation. Hardened & Precision GROUND Rectangular Boxway guide-ways, with recirculating roller bearings, are provided for all primary movements in the X, Y, & V axes. Roller Boxways provide far more metal to metal contact than radius-contact ball guide systems for up to twice the load capacity, one third the elastic deformation, twice the static stiffness, up to 200% longer life, with significantly better dampening of tool induced vibrations. Hardened and precision STAR profiled linear guide way systems with recirculating roller linear bearings are provided for movements in the Z axes. Hardened and precision ground ball screws with anti-backlash ball nuts are provided for all primary movements of the X, Y, V, & Z axis.
The vacuum tables are made of torsion resistant cast steel, covered with 30mm thick, phenolic grid table tops for the quick and easy mounting of work pieces via pods, clamps, spoil-boards, or holding fixtures. Sixteen (16) internal pneumatically controlled pop-up pins & (Six) 6 external stops for part or sheet location are included. Each table is configured with one vacuum zone, which is m-code controlled. The vacuum zones are equipped with a low vacuum sensor. This table and pump combination will allow a wide range of flexibility in holding large & small work pieces. State-of-the-art closed loop FANUC AC digital servo motors are utilized on X, Y, V, & Z axis. Automatic oil lubrication is utilized for box guide ways & ball screws. Centrally located grease fittings are utilized for end bearings and profiled linear guide ways. All guides are protected from dust and other contaminates by double sealed wipers. The operator control panel has a Handheld Pendant with separate Feed Rate & Rapid Rate Override. A dust collection hood with automatic damper system is provided for the router spindle.
