Fixture job doesn’t hold up

As a manufacturing engineer, I specify and purchase tooling and fixtures for the shop. Based on my past experiences, I typically narrow a long list of prospective vendors to a handful or fewer.

We use one of those vendors, “company A,” to make and rebuild fixtures and make subplates for fixtures and pallets. They are quite dependable. The company bid on the first new fixture I bought for our operation after I started. Their bid on that fixture was substantially lower than the other one, from “company B,” but I went with the higher-priced fixture. This is because company B is a fixture specialist.

Some months later, I was evaluating new equipment, including a machine tool. As part of that process, I visited a dealer from which I had purchased several machines. While he was demonstrating a machine, we discussed fixtures. The machine tool dealer showed me some fixtures from a company he has done business with for several years, and, boy, did they look good, with hydraulic lines neatly and robustly plumbed. The dealer had high praise for this fixture builder, “company C.”

After contacting company B and getting a quote for fixtures for the prospective new machine, I contacted company C. A representative came out and we discussed the machine our shop was contemplating purchasing, the parts we were going to machine and how to best hold them. A couple of weeks later, I received a quote on the fixtures. It was lower than the quote from company B and, this time, I decided to go with the lower bid. That project, however, was put on indefinite hold.

Later, however, our quality group needed three new fixtures for a coordinate measuring machine. I thought this would be a good opportunity to try company C since it came highly recommended. I cut a purchase order. The fixture builder sent some preliminary drawings, which I signed off on after a few changes.
