Slide Screw Repair

Slide Complete 2

Our customer had two slide adjust nuts suffer catastrophic failure when they broke in half during production. When our team pulled the slide out, they found the threads from the nuts had sheared off and wrapped around the screws and in the nut housing. The screws had damage to the threads and metal shavings and oil had collected in the housing. Our team inspected the rest of the press and found the damage was contained to the slide adjustment components.

With the slide back at our facility we were able to manufacture four new adjustment screws and four new adjustment nuts. Additionally, our team cleaned out and repainted the slide adjustment barrels, cleaned, and repainted the inside of the slide, replaced the worm gears and worm shafts, machined the bottom of the slide flat, and reassembled the adjustment components back into the slide. Once all work was complete, we transported the slide back to our customer’s facility and installed the slide back into the press.

Our customers slide adjust screws on this Minster slide wouldn’t turn due to rust that had formed on the screws, nuts, worm shafts, worm bearings, and barrel housings, from water-based die lube that was in the lubrication system.

Our team was able to disassemble the slide adjust assembly without causing damage to the adjustment nuts, worm shafts, worm bearings, barrel housings, or adjustment screws. Our team inspected each component for cracks and wear, cleaned, and polished all the slide adjust components to proper operating condition.

We machined the slide back flat, parallel, and square to OEM specifications. We replaced the customers’ contaminated oil, filters, damaged lube lines, lube orifices, installed new proper oil, gave the slide a fresh paint job, rebuilt and installed the slide, set the gibs to proper run clearances and test ran the press to ensure proper and safe operation.

All work was completed within 3 weeks.

We received this machine from the Army. The machine is specialized to make .50 caliber jacketed projectiles for the Army. This machine came to us from their on base storage facility. The machine had not been used for production in decades. Many of the functioning components for the feed and transfer systems had been scavenged from this machine over the years to keep other machines operational. Our customer wanted this machine completely rebuilt and updated with the latest technology so that they could increase production from this machine. The machine was totally disassembled. All painted components were sand blasted to remove all existing paint. The components were then all inspected and machined to OEM specifications. The crank shaft was straightened and polished; slide and frame were bored and milled to ensure parallelism. We engineered and installed an Ortlinghaus clutch conversion for this press to replace the full revolution mechanical clutch. Air counterbalance cylinders were also added to this machine to reduce press wear and increase stopping time.

We also designed and installed an Allen-Bradley Clutch/brake control kit. The Rockwell Clutch/Brake Control system used on this press is a DC version with customized code written specifically for D&S Machine Repair, Inc. It utilizes two independent MicroLogix1500 processors. Both controllers monitor all clutch/brake I/O and exchange information about machine status via hard wire I/O. Both processors independently generate operator prompts and machine faults which are displayed on the Panel View 600 Prompts & Faults Screen.

All of these features we added allowed our customer to increase production speeds while also incorporating a much higher level of die protection.
