If the Blum TC50 probe senses a problem, it will stop the machine or fix it. The Blum tool setter can re-compensate the tool so we can go back and recut it to the right size. The probe won't let you make a bad part. It takes all the human error out of the process." Prior to integrating Blum's lasers and probes, jobs could take as long as 11 hours to run. Mr. Johns says Magnolia has since tripled its capacity, delivering high-precision, small-batch work to more customers. Aside from improvements from the measuring components, the machine tools themselves also have provided a variety of benefits. For example, the new spindles extend tool life and performance, Mr. Johns says. "They're big. The heads are cooled. You can run the spindles at 14,000 rpm all day long and their heads stay at a constant temperature," he says. As a result, Magnolia is not buying as many end mills. "These new machines have nearly eliminated the grinding we used to do because they give you such a good surface finish," he says. "We used to have to grind a 1.5- by 2.0- by 2.5-inch block. The Makinos will cut that whole block out—the sides, the top—and it looks just like it's ground. We knocked 14.5 hours off of a 48-block job because we didn't have to go to the grinder anymore." With increased efficiency, Mr. Johns began actively looking for more work and new clients. With the new machines in place, he invited pro- spective customers, including a maker of high- precision medical equipment, to his shop. "Once they looked at the shop and saw our machines had part probes and tool-setting lasers, they said, 'We're going to give you a shot,'" he says. Now, he's happy to share his positive experience of upgrading to higher-qualit y machine tools and automation systems. "It seems hard to spend that much money to upgrade that far ahead, but if you have the work, it will easily pay for itself in one year."
