tion in terms of capabilities, particularly when it comes to machining speed. He said that, simply put, the Mazaks cut parts faster, and as an example, he cited a spacer part for which the QTN 350 drastically reduced processing time. With its older existing equipment, the shop completed the spacer part in 11 hours. The QTN 350 now fi nishes the part in just four minutes, and the machine’s processing speed and ef- fi ciency have opened up more oppor- tunities in a slightly smaller part size range for the shop within other sectors of the energy industries it serves. The capabilities of the QTN 350 also help reduce cycle times for another recently acquired energy industry job. The part is a mechanical inner sleeve. The QTN 350 machines the OD and ID on one half of the part, which is then fl ipped around for the other half to be machined. It also gets some grooves and threads cut in it then moves to another machine in the shop for some holes and slots. Previously, the turn- ing and threading operations took 1.5 hours. Now, the QTN 350 does them in only 40 minutes. Plant Machine Works is API licensed to cut and monogram threads under Specs. 5CT and 7-1, registered API Spec. Q1 and has ISO 9001:2008 and ISO/TS 29001 certifi cations. The shop has a fully calibrated quality control de- partment that ensures all part require- ments are fulfi lled, and its welding shop is qualifi ed in over 50 welding proce- dures for a variety of material types from carbon to stainless steel to titanium. Plant Machine Works currently ships, on average, 200 completed jobs per month and is still doing repair work. As a low-to-medium-volume shop, job- lot sizes range from two to 100 pieces, but most involve single-digit amounts. Turnaround times range from immedi-
