UPDATED BY AMERICAN HELLER 1991. The V800BC is a special purpose machine built for high precision deep hole bore applications using the stationary workpiece/rotating boring bar method. This particular machine has been tooled for skiving and burnishing. It has operating sequences and tooling for both the single pass hydraulic expansion tooling and the older push-pull tooling. This machine can be equipped with a 0-50 GPM pump to allow approximately 3" BTA Drilling and 6" Trepanning. Large quantity of skiving and burnishing heads both push-pull and hydraulic expansion types, inch and metric sizes. Cycle selector for push-pull and hydraulic expansion cycling. (3) stationary workpiece pressure heads. Guide carriage. Approximately (28) sets of skiving and burnishing tools from 4" - 11.5" bore size. Adjustable boring bar support. Approximately (8) boring bars of various sizes. Counter support with reception flange. Adaptor with various sized bore adaptors. Boring bush extender for skiving-burnishing tool change over. Boring bar clamping flanges. Main operators control panel mounted on pressure stand. Slide with controls for cycle selectors, spindle travel forward and reverse. Coolant system. Coolant flow scale. Variable coolant pressure flow. Tool clamping and unclamp. Variable forward speed variable retract speed. End support mounted operators station with controls for spindle on/off, auto cycle start, feed forward/reverse, stop, rapid forward/reverse, spindle on/off, feed forward/return, rapid forward/return, emergency stop, level operated spindle speed selector. The coolant system consists of a coolant return trough, 72" x 180" x 60" coolant reservoir with dual 25 HP speed motor. 40 HP VS drive. Belt type oil skimmer. 78" x 108" x 34" filtration tank with 15 HP pump drive and Fulflo filter model CP18-2-8FK2 cartridge type filter system. Oil skimmer. 50 psi pressing gauge. 36" x 72" x 30" tank and Polo type magnetic coil chip filtration unit. 26" wide chip conveyor.
