At the heart of the new routing system is a powerful, robust spindle with pneumatic clamping. It delivers up to 3.6 kW of power and a maximum torque of 0.7 Nm.

Zünd has introduced what it describes as robust routing option, called the RM-L router, for working with heavy-duty materials like acrylics, plexiglass, aluminums, polycarbonates, Dibond, Forex, and MDF. The spindle delivers 3.6 kW of processing power and is well suited for print service providers running diverse work that is typically processed via different tools.

In response to this ever-growing application range, Zünd’s new RM-L system is capable of routing, engraving and polishing a range of materials with what the company describes as a powerful spindle with pneumatic collet.  With a maximum torque of 0.7 Nm, in addition to 3.6 kW of power, the tool allows for dense, hard materials to be processed at greater speeds and cutting depths. It essenetially reduces the number of passes required to increase throughput.

The RM-L spindle is water-cooled for run longevity and uses what Zünd describes as a high-performance dust extraction system to keep the working area clean. The new router module is equipped with MQL, a minimal quantity lubrication system that keeps the bit lubricated to minimize friction. As a result, Zünd explains very little heat is generated during routing, which can affect bit life. This lubrication system also allows for greater acceleration and processing speeds.

The technology relies on a surface compensation system to determine the thickness of materials and detect inconsistencies. During processing, the system compensates for any variances by making the necessary depth adjustments. Particularly for engraving applications, Zünd explains this prevents quality issues arising from differences in material thickness by maintaining constant routing depths.

The system uses a ER-16 collet for concentricity and to maintain reliable retention. To accommodate different shaft diameters, HSK-E25 collet holders are used, which allows for the use of a wider range of bits with one and the same router module. The ARC HSK automatic tool changer of the system takes care of handling and changing router bits. The magazine can accommodate up to eight different preloaded collet holders.
