The Emuge Thriller/MoSys modular tooling system does the work of four tools at a fraction of the machining time and operating cost.
A single thread-milling tool is making short work of drilling operations by threading, chamfering, and spot facing in one pass. According to developer Emuge Corp., Northborough, Mass., shops using the new MoSys toolholder system with the Thriller thread-milling cutter increase productivity 70% compared to conventional thread-milling tools.
The MoSys system, in effect, combines four cutters into one tool to slash cycle times, tooling changeovers, and machine downtime. The Thriller, which has been available for several years, is a solid-carbide cutting tool with a twist-drill point, a thread-milling element, a chamfering portion, and a straight cylindrical shank with a flat for clamping. For spot facing (counterboring), users simply insert the Thriller into the MoSys holder, which incorporates an interchangeable, bolt-on, solid-carbide face-milling head.
The company reports that the cutters produce high-quality threads with good fit, form, and finish and run at high cutting speeds and feeds. Tools work best in CNC machines with helical interpolation, a minimal spindle rotation of 5,000 rpm, and an internal coolant supply delivering at least 221 psi.
One tool works for both left and right-hand threads and for through and blind holes. Because Thrillers eliminate the need for self-reversing tapping attachments, no spindle reversal is necessary.
Emuge offers a dozen tools covering three different lengths as well as UNC, UNF, metric coarse, and metric fine threads. It also custom engineers tools in terms of size, threads, machining speed, and coatings.
