Methods Machine Tools Inc. has announced the addition of the KIWA-Japan Triple H40 horizontal machining center with a column-traverse structure to its current KIWA line. One of the most unique design features of the Triple H40 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 KIWA Triple H40 has a compact machining area of 43.3" (1,100 mm) x 23.6" (600 mm) x 31.5 (800 mm). The work table stays 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 assures higher rigidity of the spindle than quill type spindles. In addition, the long-nosed spindle has six bearings for increased stability. Pallet size is 32.3" (820mm) x 17.7" (450 mm), with a maximum work height of 31.1" (790 mm) and a maximum workload of 2,200 lbs (1,000kg). Exceptionally efficient chip evacuation is possible as a result of the minimized machining area due to the moving column structure and a large opening in the bed.
The Triple H40 also features a new armless automatic toolchanger (ATC), 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.
"The Triple H40 is perfect for larger fixturing and supports good access for automation," said Bernie Otto, KIWA product manager for Methods Machine Tools. "The machine is also ideal for parts that are long and need work done on the ends."
Related Glossary Terms
- automatic toolchanger
Mechanism typically included in a machining center that, on the appropriate command, removes one cutting tool from the spindle nose and replaces it with another. The changer restores the used tool to the magazine and selects and withdraws the next desired tool from the storage magazine. The changer is controlled by a set of prerecorded/predetermined instructions associated with the part(s) to be produced.
- machining center
CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.
- payload ( workload)
payload ( workload)
Maximum load that the robot can handle safely.
Carriage or drum attached to a machining center that holds tools until needed; when a tool is needed, the toolchanger inserts the tool into the machine spindle. See automatic toolchanger.
