For manufacturers that witness the scourge of stringy swarf when using small boring tools to machine materials such as unleaded brass or aluminium, Floyd Automatic Tooling is introducing the UK market to a new addition to the Ifanger MicroTurn internal boring system.

The new Ifanger MicroTurn is available in two different types: the MicroTurn MTEP for rough internal turning and boring; and the MicroTurn MTEF for finishing operations. Each of the designations comes in three product length ratios of 2xD, 3xD and 5xD that presents tools from 26 to 53 mm in length. Supplied with a through-coolant facility, the MicroTurn series is available with a 4 or 6 mm diameter solid-carbide shank that minimises vibration while enhancing strength, longevity, tool life and performance.

Ifanger’s MicroTurn MTEP for roughing is available in diameters from 2.5 to 6 mm diameter, enabling manufacturers to efficiently machine bores and intricate internal features from 2.5 mm diameter and upwards with high productivity levels. To achieve even greater results when machining non-ferrous alloys, Ifanger can offer the MicroTurn series with an optional diamond-like coating (DLC) that can ramp up productivity and tool life performance on a host of materials.

Complementing the MicroTurn MTEP for roughing is the MTEF for finish turning. The geometry of the MTEF presents high-quality surface finishes and performance when conducting turning operations on small bores. To maximise performance on the smallest and most detailed bores from 1 to 2.2 mm diameter, the MTEF has a sharp edge for high precision while tools from 2.5 to 6 mm incorporate a 0.05 mm corner radius to prolong tool life and reliability.

Among the highlights on the stand of tooling expert Mapal at the EMO exhibition in Hanover last month were the deep drills of the company’s new MEGA-Deep-Drill-Steel product range. Designed for machining steel and cast iron, users can achieve depths up to 40xD.

The solid-carbide deep drills feature protection via a coating with HiPIMS technology in the cutting edge area, ensuring frictionless chip removal. The remaining length of the MEGA-Deep-Drill-Steel remains uncoated. Thanks to its geometry, Mapal says the new deep drills stand for long tool life and high productivity. Compared with its previous-generation tools, it is possible to can attain up to 50% higher feed rates.

Mapal also presented a series of new cylindrical shank reamers with brazed cutting edges. A special feature of the FixReam 700 reamers is their high usability, derived from an expansion system. It is possible to re-grind a tool twice before new cutting edges require brazing-in. After that, the tool can benefit from two more re-grinds before replacing the cutting edges again and performing yet two further re-grinds. Tool costs reduce by up to 15% in comparison with a tool that does not have an expansion function. Furthermore, thanks to new (patented) geometries, users achieve up to 30% better roundness and cylindrical form, as well as improved chip removal, compared with other cylindrical shank reamers.

Also taking the spotlight at EMO was Mapal’s new OptiMill-Alu-Wave for aerospace customers, a tool that can deliver material removal rates of up to 21 litres per minute when machining aluminium.

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.
