HMC Design Offers Machining Rigidity

Methods Machine Tools will introduce the Kiwa-Japan Triple H40 HMC with a column traverse structure.

Methods Machine Tools will introduce the Kiwa-Japan Triple H40 HMC with a column traverse structure. The machine supports flexible mounting of various fixtures and rotary tables based on the application. Its stationary table design enables long workpieces to be clamped to the table, eliminating the back-and-forth action of moving parts with special guarding, and enabling machining access to either ends of long workpieces.

The compact machine has a work envelope of 43.3" × 23.6" × 31.5" (1,100 × 600 × 800 mm). The work table remains stationary and the X-, Y- and Z-axis ballscrews and roller guides are behind the X- and Y-axis way covers.

The Z axis moves back and forth on the column, which promotes a higher rigidity of the spindle. In addition, the long-nosed spindle has six bearings for increased stability. Pallet size is 32.3" × 17.7" (820 × 450 mm), with a maximum work height of 31.1" (790 mm) and a maximum workload of 2,200 lbs (1,000 kg). The minimized machining area due to the moving column structure and large opening in the bed enable efficient chip evacuation.

The product features an armless ATC mounted on the top of the machine, which enables the spindle to directly change tools with the magazine, eliminating the need for a tool change arm. This feature is available in a 20- or 40-tool system.
