We want to enhance our competitiveness by introducing a more productive production line.
Using Muratec’s flexible gantry loader to compactly integrate the current production line!
Minimizing human intervention to build a highly productive line!
- First of all, we started reviewing the conventional machining processes performed by the “2 lathes and 1 machining center.”
In order to integrate several machining processes into one machine, we proposed a plan to use an index chuck that allows four surfaces to be machined in one chucking. Although the cycle time per spindle became longer due to the above process integration, the line takt-time has been shortened as much as possible by using the twin-spindle turning machine to perform the same machining operations with two spindles.
- In the automatic production of odd-shaped workpieces, it is generally difficult for the loader to handle the workpieces, but our “twin-jaw chuck loader” enables smooth handling.

The loader-based production system has allowed for more stable operations than the conventional manual handling line. Errors caused by workers and quality variation due to re-chucking of workpieces between processes have been eliminated, resulting in a significant improvement in productivity.
Initially, the customer had a plan to connect the previous three machining units with robots.
However, our system has enabled to save the floor space by as much as 50% compared to that plan. As a result, the productivity per unit area has increased significantly.
The product in the case study introduced here is the Twin Spindle CNC Chucker ”MW120Ⅱ”
