Guhring is extending its Diver series of end mills for the micro-machining sector. Coined by the company as the ‘smallest diver in the world’, the new RF100 Micro Diver end mills machine small components of any material.

Providing plunging and milling in a single tool, Guhring says that the RF100 Micro Diver permits very high cutting depths that until now, were beyond the realms of micro-precision cutting tools. Available in two variants, the 6808 and 6809, the RF100 Micro Diver features a symmetrical drilling face for stability when ramping and drilling, a new transition geometry to improve rigidity, and a novel flute form that further enhances rigidity and eliminates vibration.

The RF100 Micro Diver 6808 series is a three-flute solid-carbide end mill suitable for cutting materials up to 48 HRc at depths up to 2.5xD. With a 40° helix angle to evacuate chips from the work area when conducting high-speed machining, the 6808 series is available with a H5 4 or 6 mm shank diameter and a H8 cutting diameter from 0.79 to 3.175 mm (with a multitude of dimensional increments available).

For the machining of pockets and slots up to 5xD, manufacturers can select the longer 6809 series, which offers an overall tool length from 45 to 57.15 mm with a 5.00 to 15.87 mm cutting length.

From a tool life perspective, both end mills have an optimised geometry that adds strength and rigidity, while Guhring says that its new HIPIMS Durox coating enables end users to achieve a very high surface finish with optimal chip-removal rates.

With the recent pandemic forcing more businesses to look at their costs, Floyd Automatic Tooling has given a UK launch to the MicroTurn eLine of boring tools from Ifanger. The MicroTurn eLine MTEE is an optimised universal boring tool that is 25% less expensive than Ifanger’s existing MTEC or MTEN tools.

Available as a right-handed boring tool in seven variants, the universal inserts are suitable for small-bore machining starting from 1.80 mm diameter. With the new eLine MTEE, the series incorporates a positive-cut 8° rake angle and a short neck length for rigidity and stability.

From a dimensional perspective, the MTEE line is available with a 4 or 6 mm diameter shank, and an overall length of 31 or 43 mm. Neck lengths range from 5 to 19.5 mm, while corner radii extend from 0.05 to 0.15 mm. MTEE-series inserts are currently available uncoated, which retains edge sharpness and precision when machining certain materials, and with a TiALN coating.

Complementing the MTEE line is the classic series of Ifanger boring inserts that incorporates the MTEC, MTEN, MTKE and MTKH boring and copying tools. For profiling applications, Ifanger has a diverse range of geometries and coatings to support manufacturers with all their threading, grooving, chamfering and axial plunging requirements.

Although the new MTEE line caters for the majority of small boring applications with the most commonly-used dimension ranges initially available, Floyd Automatic Tooling and Ifanger can customise this extensive range upon demand.
