ownership investment, the addition of new round product tool- ing capabilities, and a renewed commitment to the toolmaking trade. As Contour Tool, the company has been a one-stop resource for OEMs needing an integrated knowledge and approach to building molds for injection- molded plastic parts. For True Die’s leadership team, two decision paths have emerged: Invest in newer basic machines that give a machine operator the ability to cut a part, or invest in more capable machine/control packages that enable employees to build their skills, their careers, and the company. In 2014, the company bought its


fi rst D1000AP vertical machining center from Romi Machine Tools (Erlanger, KY), featuring the Sinumerik 828D con- trol and drives package from Siemens Industry Inc. (Elk Grove Village, IL). “We initially wanted higher speed and accuracy,” Tim Rietsma said. “With the molds, you cut both halves of the tool, then both halves need to fi t tight to each other within one-thousandth of an inch. If your machine can’t do this, you must spend a lot of time with a hand grinder on a bench.”


Doing away with bench grinding


proved to be one of the immediate paybacks of the Romi-Siemens invest- ment. Any grinding related variances in precision and surface quality were soon avoided, and the profi tability of the business was boosted by the increased capacity for throughput. “Three years ago, most of our surfac- ing work was done at a feed rate of around 50–60 ipm [1.27–1.5 m/min/],” said Tim Rietsma. “With the Siemens and the Romi combination, some of our feed rates have already approached 200 ipm [5 m/min]; and what comes out of the machine is a part cut in much less time, and that offers repeated high qual- ity to the customer.”


The Romi D1000AP VMC features integrated cooling during high-speed drilling. The coolant fl ows through the drill bit to fl ush the metal chips out and away from the fl utes. Carbide drill bits last much longer and drilling cycles have
