Kiwa Triple H40 HMC Supports Flexible Fixture Mounting Based on Application

Originally titled 'HMC Supports Flexible Fixture Mounting Based on Application'

One of the design features of the HMC is its ability to support flexible mounting of various fixtures and rotary tables based on the application.

Methods Machine Tools Inc. has added Kiwa-Japan Triple H40 HMC with a column traverse structure to its current Kiwa line. One of the design features of the HMC is its ability to support flexible mounting of various fixtures and rotary tables based on the application. The stationary table design enables long workpieces to be clamped firmly to the table, eliminating the back and forth action of moving parts with special guarding and allowing machining access to either ends of long workpieces.

The H40 has a compact machining area of 43.3" (1,100 mm) × 23.6" (600 mm) × 31.5 (800 mm). The work table stays stationary, and the XYZ-axis ballscrews and roller guides are behind the XY axis way covers.

The Z axis moves back and forth on the column, which assures higher rigidity of the spindle compared with quill-type spindles, the company says. The long-nosed spindle has six bearings for increased stability. Pallet size is 32.3" (820 mm) × 17.7" (450 mm), with a maximum work height of 31.1" (790 mm) and a maximum workload of 2,200 lbs (1,000 kg). Efficient chip evacuation is possible as a result of the minimized machining area because of the moving column structure and a large opening in the bed, the company says.

The Triple H40 also features an armless automatic tool changer mounted on the top of the machine to save space, which allows the spindle to directly change tools with the magazine, eliminating the need for a tool change arm. This is available in a 20- or 40-tool system.
