Enhancement packages for older 4-Spindle Chuckers and 1-2-3 Rotary Transfer Machines are available for existing or remanufactured machines

Programmed thread counting is an example of the Goss & Deleeuw Machine Enhancements Programmed thread counting offers three advantages:

1. Change-over time is dramatically reduced, since the trial-and-error method of establishing the length of thread is completely eliminated. The number of turns required is entered directly into the LED read-out mounted on the gear box. Change-over is further reduced since all thread spindle speeds are dialed directly, thereby eliminating the need for changing threading gears.

2. A second advantage is high-speed threading reversal. Since threading very often controls the cycle, the ability to return the threading spindle in its lead screw at three times the speed that the threading took place can dramatically reduce the cycle time without requiring higher speeds and feeds on the cutting tools.

3. The third advantage, which applies to 4-spindle machines, is that the maximum cycle capability is 900 cycles per hour, an increase of approximately 40% over the potential output of the older designs. Reduced change-over time with higher productivity result from the Goss enhancements, which are available today.

The pneumatic shifting enhancement available on 1-2-3 Rotary Transfer Machine utilizes "state of-the-art" proximity switches and pneumatic cylinders, eliminating the existing mechanical trips. The infinitely adjustable trip disc permits optimization of feed stroke and dwell, which can significantly contribute to productivity. The new shifting enhancement is a positive system, which simplifies the normal maintenance.

The addition of an automatic lubrication system to provide positive lubrication to critical points is a must in today’s high production environment. Our positive lubrication enhancement option is incorporated into the machine tool’s electrical control system to effect an orderly shutdown should a lubrication failure occur.

Any machine, which is remanufactured today, can be fitted with thread spindle safety interlock, which prevents index from taking place until all tapping spindles have been returned to their starting positions. This is an extremely important enhancement, when one considers the cost in dollars and lost production time resulting from operator damage to the threading equipment during setup.
