Success Stories

At CAD we have the resources to turn your problem parts into success stories.

Expensive Machine Part

Problem- These anodized aluminum samples were submitted to CAD for manufacturing. While in use the small part is in constant motion, sliding in and out of the slot in the large complex part. Both were wearing out regularly and had to be replaced often. The large part was very expensive to replace.

Solution- The large part was reverse engineered and then altered to allow the installation of hardened steel ware plates in the slots, and the small part material was upgraded to a more durable Aluminum alloy. Now only the small less expensive part wears and is replaced periodically. If the hardened steel ware plates eventually wear out they can be replaced. Now the large expensive machine part will last virtually forever.

Slides

Problem- These aluminum slides were submitted to CAD for manufacturing. In use they slide rapidly against one another while supporting a load. Before manufacturing an engineer from CAD discussed the part with the customer’s machinery repair manager. The slides from the OEM were wearing out every six weeks, and were difficult to change, resulting in expensive down time. The ambient temperature in the machine where the slides operate was over 500 degrees Farenheight causing the Aluminum to break down rapidly.

Solution- CAD reverse engineered the slides and mechanical drawings were produced. The material of the replacement parts was upgraded from Aluminum to bronze and hardened steel. The new replacement slides were manufactured. CAD’s slides now last for over a year before wearing out.

Squeeze Jaws

Problem- These squeeze jaws are used in the Aerospace industry to squeeze rivets. While in use a colossal 5000lbs of force is generated on the ends. The old jaws would break unexpectedly causing damage to products and employees. Also the end user had no mechanical drawings for reproduction, only worn out broken samples from the OEM.

Solution- We reverse engineered two broken jaws and created mechanical drawings. The material was upgraded to a stronger tool steel. After machining, the replacement squeeze jaws were heat treated to a precise Rockwell rating that increased tensile strength and tool life. Now CAD manufactures all of the replacement Jaws.

Screwed

Problem- This segment of screw conveyor was submitted to CAD for manufacturing. The thread was .625 wide and the pitch was .5 threads per inch. Because of a caustic environment the material had to be 316 Stainless Steel. The only problem? The finished length was over 40 feet long!

Solution- Four separate screws were milled from 1 1/4" round bars in a HAAS rotary 4th axis. Then each bar was fitted together and timed to create the length needed by the end user.
