Tool Magazine for 70 Grinding Wheels
The tool changers we usually equip our Multigrind® CA grinding machines with are enough for most applications. But the pressure of rising costs is now forcing manufacturers of aerospace components, medicinal products and machining tools – to name just three industries – to seek out new opportunities to save. So we developed the Haas storage magazine with an unbelievable 70 spaces.
Tool magazine minimizes setup costs
Minimizing setup costs is one option for reducing unit costs. In other words, workpieces should be machined in a single clamping if at all possible. All of the necessary grinding or milling tools therefore need to be at the ready in the tool magazine, for tool changing in a flash. Further benefits include increased dimensional accuracy and thus product quality, as errors resulting from re-chucking are eliminated.
Tool change in ten seconds
One side of the Haas storage magazine (2,000 × 2,400 × 3,200 mm, L × W × H) offers space for 70 grinding wheels with diameter of 300 mm. The other side features 20 coolant nozzles. The storage magazine stands on four levelling feet at the back of the grinding machine, but is not mechanically connected to it. It goes without saying that the new tool magazine is integrated into our Multigrind® Horizon grinding software.
The interface to the grinding machine is the shuttle table in the machine. The storage magazine’s linear handling is responsible for transporting grinding wheels and coolant nozzles. The linear axes offer a speed of 60 m/min and acceleration of 5 m/s2. The magazine is loaded via the loading door. Grinding wheels and coolant nozzles are lined up one behind the other and, once the door is closed, selected by the handling system and placed at the specified location. The machine’s shuttle table replaces the usual tool changer and, with a linear and swivel axis, takes over grinding wheel and coolant nozzle handling in the workspace. A safety door protects the storage magazine from oil mist. All in all, it only takes the grinding machine ten seconds to change the tool!
