Automate in less shop space

Whether your preference is a vertical or horizontal unit, you can buy a new machining center that automates the production process without hogging too much space on the shop floor.

One example is the recently introduced Supercell-300G 5-axis horizontal manufacturing cell from Kitamura Machinery of USA Inc., Wheeling, Illinois. Able to hold 20 pallets in a 149″-wide footprint, the Supercell-300G is capable of unmanned production of small and medium-size parts made of a variety of materials, including stainless steel, titanium, Inconel and aluminum. The machine offers 2µm positioning accuracy and 1µm repeatability, according to Sal Swierczek, Kitamura’s assistant sales manager.

Although the machine comes standard with a 20-station automatic pallet changer, arrangements with as many as 80 pallets are available as an option. The pallet tables are 7.9″ in diameter, so the machine wouldn’t be the right choice for manufacturing large parts, Swierczek noted.

Located in front of the machine, the pallet changer features Kitamura’s unique “wide open” design that gives operators access to all the pallets at any time, according to Swierczek. “With this pallet magazine, customers can load their parts onto the pallets and then go on to other tasks,” he said. “For companies that don’t have many employees, that frees them up to do other operations or attend to other machines.”

In addition, the HMC offers a so-called “dual-contact” spindle. Normally, the toolholder makes contact with the spindle in only one place. For increased rigidity, however, this machine’s standard 20,000-rpm spindle touches both the toolholder shank (taper) and flange.

The Supercell-300G also comes with a 174-tool matrix-style automatic toolchanger. The matrix magazine allows many tools to be loaded in a relatively small space and can also speed up tool changes in applications involving complicated parts that require a large number of tools. Additionally, Swierczek pointed out that the tool matrix enables the machine to “stage” tools so they are in position to be tapped for upcoming operations, which reduces tool-changing time.
