When a router is cutting, it’s making money. When it’s idle, it’s not. That simple proposition is one basis of the appeal of Techniks Inc.’s modular aggregate heads, which can hold multiple cutting tools. They expand a CNC router’s capabilities by allowing use of the same aggregate with a variety of saw, router bit, collet, and arbor options. Loading these heads into a tool-changer allows it to combine routing, drilling, sawing, and mortising operations. This can increase CNC router productivity.

Modular aggregates are available for any CNC router, and come in one, two, or even four outputs, compatible with ER25 and/or ER32 collets, cutters, and saws. Techniks says it also will also custom-build aggregates.

Indianapolis-based Techniks, which will be exhibiting at AWFS Fair (Booth 4315), has been manufacturing tool holders for all popular machine spindles since 1997. Each of its tool holders comes with a full report documenting its inspection, and Techniks says it is certified to meet highest standards for runout, taper accuracy and balance. Each holder is factory balanced to 25,000 rpms, with custom balancing is available. Techniks says it uses a special “Power Coat” nut that holds 75 percent tighter than standard nuts for improved safety.

“Aggregate heads enable CNC routers to perform tasks they could not do before, like shaping, sawing, and drilling at difficult angles”, says Greg Webb, sales manager at Techniks. “Combining different tasks into one, and reducing the number of tool changes needed can have a big impact on production runs”.

Techniks makes hundreds of different types of aggregate heads to suit specific operations, but a popular choice is its modular aggregate head (shown here). The modular output option allows use of the same aggregate with a variety of saw, router bit, collet, and arbor options. For example, the same output you use for an ER32 router bit, can be used to run a saw or cutter just by changing the modular connection. This is a good way to increase CNC router productivity and reduce the number of aggregates needed.

Another popular option is the floating aggregate head that Techniks says accurately follows the contours of the stock so cutting depth remains constant, even if the surface varies by as much as 10mm. This aggregate comes standard with a floating bell, and an ER 25 or ER 32 spindle output, and such options as a variety of floating bells, shoes, and sleighs that are all interchangeable, and various spindle outputs. For improved dust control, Techniks recommends the chip guide, which evacuates dust straight up into the exhaust hood.
