The new product has three spindles arranged in a horizontal arrangement on the column, and is equipped with three turrets that hold the workpiece and rotate on the "bracket mechanism" on the side of the table. The workbench is located on a carriage mechanism in which three turntables are assembled.
The spindle can be moved in three directions of the X-axis in the depth direction of the body, the Y-axis in the vertical direction, and the Z-axis in the horizontal direction. The table is equipped with an A-axis for indexing and a C-axis for rotating the workpiece. Therefore, although there are multiple spindles, they still belong to the 5-axis control MC in the machine classification.
Further, a W rotating shaft identical to the A axis is provided on the bracket mechanism on the table side. However, unlike the A-axis for workpiece indexing angle adjustment, the W-axis is used to replace the tray. The shape is just like a two-sided pallet changer. If the workbench located on one side of the carriage mechanism is received in the machine tool processing chamber, the other surface is exposed outside the machine body.
With this, when machining three workpieces fixed to one table, the machined workpiece can be detached from the other table, and the workpiece before the processing can be loaded. This can increase the operating rate of the machine and shorten the total machining time.
In addition, in order to automate these preparations, a "robot unit" is also employed. The vertical multi-joint robot performs the fixing and dismounting of the workpiece, and strives to reduce labor costs.
Desamag develops a 3-spindle horizontal MC that reduces machining time
SAMAG has developed a horizontal machining center (MC) with three spindles that can machine three workpieces at a time, and the European Machine Tool Show held in Hanover, Germany, September 17-23, 2007 ( EMO2007)" was on display. Since multiple workpieces can be machined at the same time, the actual cutting efficiency can be improved and the total machining time can be reduced.
