Loadpoint-dicing-machine-macroace-II-2

The MacroAce II

MacroAce II for heavier duty applications requiring high power spindle delivery and large work areas. The MacroAce II offers a unique combination of dicing machine performance with CNC-like power and work area capability.

The spindle’s drive profile has been optimised to give maximum 4KW power delivery in the 1,000 – 10,000rpm range, exactly where it is required for heavier duty ceramic and metal cutting applications.

Additionally, cut depths of up to 55mm with cut lengths of up to 450mm help make the MacroAce II a best-in-class leader.

The MacroAce II is frequently the first-choice system for cutting bulk ceramics and lower frequency PZT sonar arrays.

The performance of the MacroAce II is underpinned by the Loadpoint NanoControl control system; a common control platform used across all  machines.

 NanoControl can be tailored to a customer’s application. This could be taking the hassle out of calculating complex cut patterns or the easy generation of 3D cutting profiles.
