Methods Machine Tools Inc. offers the KIWA-Japan KH-55 Horizontal Machining Center, a heavy-duty machine with a range of features designed to accommodate precision machining of a variety of large work components. The 50-taper KH-55 can machine workpieces of up to 35.4" x 39.4" high (900 mm x 1,000 mm) in size, and 1,650 lbs (750 kg) in weight.
"Large component machining requires exceptional machine tool rigidity, which the KH-55 provides with a box-type structure where the bed, column and spindle head are symmetrically designed to uniformly absorb force," said a company spokesperson. "The column also has an elevated X-axis roller guide design, which increases rigidity while reducing column weight."
Spindle speed is 10,000 RPM with spindle acceleration time of 2.95 seconds and deceleration at 3.32 seconds. Tool-to-tool and chip-to-chip times are 1.8 and 3.8 seconds, respectively. The KH-55 features a full rotary B-axis and will also be available with a 15,000 RPM, 40-taper spindle as an option.
The KH-55 also features the KIWA exclusive in-the-field expandable tool and pallet technology. Expandability allows shops to upgrade the KH-55 from a 2-pallet machine with 60 tools to a 6-pallet machine with up to 240 tools. The machine can also be equipped with optional 630 mm pallets.
KIWA features include spindle thermal displacement compensation to help ensure accuracy and stability, and a ballscrew cooling system that regulates oil temperature, minimizing thermal expansion. In addition, a comprehensive tool management program provides information such as tool number, life, status, feed rate, etc.
Other specifications include an XYZ stroke of 31.5" x 31.5" x 31.5" (800 mm x 800 mm x 800 mm), a 20" x 20" (500 mm x 500 mm) pallet size, rapid traverse of 60 m/min (2,362 IPM), 47 HP direct drive spindle and FANUC 31i-A CNC control.
The KH-55 also has design features such as a center-trough chip evacuation system and an easy-access maintenance system in one convenient location at the rear of the machine.
