FOR IMMEDIATE RELEASE
ARLINGTON, Vt. (Feb 8, 2011) – Mack Molding has extended its vertical integration of services, investing $1 million in the development of a full-service Machining Center at its headquarters plant. “The growing demand for milling and turning work, combined with our drive to further compress lead times for our customers, made this a very easy decision,” says Jeff Somple, president of Mack’s Northern Operations. “As a growing supplier to the medical device and orthopedic markets, we see a lot of opportunity for this service.”
The primary equipment purchases include a Mazak Integrex Mark IV turning and machining center, and two Citizen A20VII lathes. “The Integrex is the workhorse,” says David Hoffman, CNC supervisor. “With its advanced multi-tasking technology, it can perform high-powered turning and full-function machining in a single setup. This reduces lead time for our customers and allows us to produce small lot sizes in a cost-efficient manner.” Part accuracy is also improved by eliminating multiple setups. The Integrex is equipped with 40-tool capacity, a touch probe tool setter, KM63 dual contact tool connection, two-inch thru-capacity, and an LNS Servo 65 bar feeder.
The Citizen Swiss lathes are 7-axes, 20mm machines with 21 tools each. Equipped with an additional axis on the subspindle, they can machine on both the front- and back-ends simultaneously. “This feature, along with 32m/min rapid feed rates, significantly reduces cycle times,” adds Hoffman. The lathes are coupled with C-320 barfeeders with 3-20mm barstock capacity using +0.0000″/-0.0005″ precision ground stock.
Both the Integrex and Citizen lathes have fully integrated CAD/CAM systems that allow the customer to see the actual process before the first piece of metal is cut. “PartMaker allows us to take the part from a solid model to a complete 3D simulation, and then to the machine G code,” says Hoffman. MatrixCam provides offline conversational programming on the Integrex. Other auxiliary equipment includes ultrasonic parts washing, vibratory tumble deburring, a 14-inch optical comparator, and a surface finish analyzer.
Now fully operational, the Machining Center produced first parts in late fall 2010. Management staff is in place, with 10-15 additional employees planned as the service grows to a two-shift operation.
