Drilling and tapping centers

The vertical model self-center provides an economical alternative to machining centers for mass production efficiency of precision small parts requiring six tools or less.

The vertical and horizontal drilling and tapping centers are capable of high-production output for drilling, tapping, facing, reaming, chamfering, and other machining functions in ferrous and nonferrous metals.

The V6 features a six-station, automatic tool changer mounted on a traveling column. Using a fixed-position worktable, all movements of the X, Y, and Z axes are performed on the column to permit interference-free access to loading and unloading of parts.

The machine is powered by a 3-hp AC servomotor. A 6000-rpm spindle speed offers versatility.

Synchronous tapping is 3000 rpm maximum, with Class 3 thread accuracy. Cutting feed is 0.033 ipr at 6000 rpm. Feedrate is 11.83 ips X and Y, and 9.81 ips Z-axis. Length of X-travel is 11.8", and Y and Z travel is 9.8".

Table size for the V6 is 12" x 20" with table-loading weight at 550 lb. The machine is available with a 180-deg turntable, index table, splash guards, chip conveyor, magnetic chip separator, work counter, and coolant unit.
