The material handling series utilizes coolant or air pressure, or spindle rotation power to clamp workpieces and jigs by simply attaching them to the machining center to achieve stable workpiece/jig transfer. Furthermore, various clamping methods can be proposed according to the shape of the workpiece or jig. This enables workpiece/jig transfer within the machining center, contributing to “automation”, “investment reduction”, and “improvement of equipment utilization”.
How to use material handling holder
Case A) Transport of raw materials and finished workpieces
① Moving the raw material to the machining location
② Workpiece machining
③ Moving the machined workpiece to the finished product storage area
Case B) Workpiece changeover on a 5-axis lathe machine
① Workpiece machining
Clamp the workpiece with the main spindle
Push the center to the sub spindle and hold the workpiece
② Center removal / transport
Switch tool to material handling holder
Remove the center from the second spindle and store it in the tool magazine
③ Changing the workpiece
Transferring the workpiece from the main spindle to the sub spindle
④ Opposite side processing
The opposite face is machined
Development / product concept
“Current status and challenges”
Conventionally, jig changeover and workpiece attachment and transfer have been performed by robots or manual labor.
However, robots are expensive and difficult to install, while manual work is time-consuming and needs the equipment to stop, resulting in a lower equipment utilization rate.
“Development points”
The “material handling series” utilizes three types of power sources (coolant pressure, air pressure, and spindle rotation) to enable workpiece transfer and jig changeover in the same equipment as the machining center, realizing “automation”, “investment reduction”, and “improvement of investment utilization rate”.
