machines weren’t able to consistently hold tolerances without an operator continuously monitoring the program, and often required additional benchwork and hand polishing to meet requirements. The F5s changed all that.


Hetherington estimates that with the F5s in place, down-


time for repairs or maintenance has been improved by 100%. As a result, jobs can be set up and run untended for six hours or longer during the second shift with only one operator on duty. The reliability of the equipment has also given Franchino the confi dence to run some mold components over the weekend with no one in the shop.


Each F5 is equipped with the Makino Professional 5 con-


trol, which comes with an easy-to-use touchscreen interface and provides operators with convenient access to the tools and information necessary to program and process cavity components quickly and effi ciently. The 30% cycle-time improvement Franchino has realized is due in no small part to how well the control assists the operators, Hetherington said. One of the key process improvements SST and Makino engineers recommended was a standardization of the machines’ toolchangers. Each F5 has an automatic toolchanger (ATC) loaded with the same fi rst 15 tools. Additional tools fi ll out the 30-tool magazines as needed, simplify programming and enable Franchino to defi ne and standardize processes. Franchino also has cut in half the amount of time required for polishing and other benchwork because the rigid F5s cut accurately and consistently. A program can be set up and tuned on one machine, then transferred to some or all of the other F5s. No matter how busy the shop is, or which operator is scheduled, Franchino can easily accommodate engineering modifi cations and production schedule changes without affecting quality. “We now can take details off one machine and put them on any one of our six Makinos and be confi dent that it’s going to run exactly the same on any of our machines,” Hetherington said.

“One of the biggest things we have now with the Makinos that we didn’t have before is the ability to trust that they’re actually going to do what we tell them to do,” Hetherington said. “We don’t worry about the machines going down or not making it through the programs that we run. We are able right now to send a program to the machine and go home for the weekend, and rely on the fact that the machine is going to be running when we come back in on Monday.”


Secondary Finishing Cut 30 to 40% Blending issues are a common problem for manufacturers when they have to use two or more cutters of different sizes. With the Makino F5s, Franchino no longer has to worry about those issues; the repeatable accuracy of the F5s has eliminated that problem, because the rigid design of the machines reduces chatter. Core-cooled


spindles, thermal-controlled spindle jackets and high-pres- sure through-spindle coolant also ensure long hours of rigid, stable cutting. In addition, the Professional 5 control quickly manages more tool points, and an automated tool-length monitor ensures tool integrity. The cutting feed rate reaches 787" (2000 cm) per minute. “The F5s’ capabilities are just amazing,” said Jim Walter, Franchino Mold’s CNC supervisor. “They process
