Guhring is extending its Diver end mill series into the micro-machining sector. Claimed as the ‘smallest diver in the world’, the new RF100 Micro Diver end mills provide plunging and milling in a single tool. 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 special 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. This range has an overall length from 38.1 to 50.8 mm and a cutting length from 1.97 to 7.93 mm, with the choice of four or six peripheral through-coolant channels available. To enhance tool life further, the end mills incorporate a 45° corner chamfer to prevent edge chipping when machining challenging materials.

Guhring’s new RF100 Micro Diver 6809 series is for the machining of pockets and slots up to 5xD. Like the shorter length variant, the 6809 series offers the choice of four or six peripheral through-coolant channels, a H5 4 or 6 mm shank diameter and a 45° corner chamfer to prevent edge chipping. In comparison to the shorter 6808 variant, the 6809 offers an overall tool length from 45 to 57.15 mm with a 5.00 to 15.87 mm cutting length.

According to Floyd Automatic Tooling, the Applitec TOP-Line 700 series is the tool of choice for precision turning, parting, grooving and profiling on small turning centres and sliding-head lathes. Applitec,which has its headquarters in Switzerland,isexpanding its range with the introduction of an entire line of PCD-tipped inserts that are now available in the UK from Floyd Automatic.

With the introduction of this line of PCD inserts, Floyd Automatic can present the benefits to manufacturers machining a diverse range of non-ferrous materials, including precious metals, copper, brass and bronze, through to more challenging materials such as aluminium alloys, composites, thermoplastics, graphite and lead-free brass.

With its serrated insert teeth, corresponding tool-holder and two insert screws that combine to deliver precision and repeatability, Floyd Automatic says the Applitec 700 series provides rigidity, stability, high performance and astounding surface finishes. Utilising Applitec’s proprietary twin-screw offset teeth insert location system, the two clamping screws pull the teeth together so the insert does not vibrate.

Like the existing carbide version of coated indexable inserts in the 700 series, the new 700 PCD line is available with a range of parting-off inserts, front and back turning inserts, and grooving and turning inserts. Each of the cutting tools for the respective processes is available in a range of geometries, insert widths, lengths and radii, with both left and right-hand designations to cater for the diverse needs of the marketplace.

The TOP-Line 700 PCD series will extend tool life and deliver more consistent results when compared with solid-carbide tools, reports Floyd Automatic: months rather than weeks or days. In addition, the latestseries can run at machining parameters up to 10 times faster than solid-carbide tools, reducing lead times and increasing throughput.
