Emuge’s solid carbide micro end mills are specifically designed to meet the requirements of micromachining applications. A geometrically optimized cutting edge combines with a slim, concave, tapered neck to provide flexible, high-performance milling solutions in materials ranging from 66 HRc hardened steel to graphite.
The 300 new micro end mills are available in 24 designs encompassing ballnose, torus and flat-end styles. For added versatility, the tools can be uncoated or coated with TiAlN. An optional diamond coating is also available. The tools are available with cutting diameters ranging from 0.2 to 2 mm (0.008" to 0.080") with length-to-diameter ratios of 2.2:1, 5:1 and 10:1. The tools are manufactured to optimize performance, durability and tool life, the company says.
According to the company, the end mills feature the latest developments in tool design, carbide selection and coating technology. They are designed for milling injection molds and extrusion dies, and graphite and copper electrodes. They are also said to be well-suited for high-precision surface structuring of macroscopic components as well as micro-mechanical parts production.
Hitting the Coolant Sweet Spot
Toolholders with integrated cutting fluid delivery channels offer threaded, fixed-position nozzles that direct parallel streams of coolant to pre-defined positions at the top of the cutting tool.
