Desamag develops a 3-spindle horizontal MC that reduces machining time
SAMAG has introduced a groundbreaking horizontal machining center (MC) featuring three spindles, allowing the simultaneous machining of three workpieces. This innovative machine was showcased at the European Machine Tool Show (EMO2007), held in Hanover, Germany, from September 17 to 23, 2007. By enabling the processing of multiple parts at once, this technology significantly boosts cutting efficiency and reduces overall machining time.
The new model is designed with three spindles arranged horizontally on the column, complemented by three turrets that hold the workpieces and rotate via a "bracket mechanism" located on the side of the table. The worktable itself is mounted on a carriage system that incorporates three turntables, enhancing flexibility and productivity.
Each spindle can move along the X-axis (depth direction), Y-axis (vertical direction), and Z-axis (horizontal direction), providing precise control. Additionally, the table is equipped with an A-axis for indexing and a C-axis for rotating the workpiece, making this machine a true 5-axis control machining center despite the multiple spindles.
An additional W-axis, similar to the A-axis, is integrated into the bracket mechanism on the table’s side. Unlike the A-axis, which adjusts the workpiece angle for indexing, the W-axis functions as a dual-sided pallet changer. When one side of the worktable is inside the machining chamber, the other side remains accessible outside the machine body.
This design allows for continuous operation: while one set of workpieces is being machined, another set can be loaded or unloaded without interrupting the process. As a result, the machine’s utilization rate increases, and the total cycle time is shortened.
To further enhance automation, SAMAG has incorporated a "robot unit." A vertical multi-joint robot handles the loading and unloading of workpieces, reducing manual labor and lowering operational costs. This integration marks a significant step toward fully automated manufacturing processes, offering both efficiency and cost-effectiveness.
