The latest addition to Guhring’s hole-making portfolio is the RT100XF. Created to reduce cycle times for difficult-to-machine materials and special applications in series production, the hard drilling line is said to be extremely resilient to potential breakages.

This bold claim is based upon the carbide grade developed by Guhring for the RT100XF, which performs a balancing act between hardness and toughness. The special structure of the grade has a re-sharpening effect, so breakages that normally accelerate tool wear no longer occur. This effect is supplemented by the company’s existing nanoFire coating system, which has been created by a specially designed pre and post-treatment that smooths the coating and makes it significantly more robust.
RT100XF supports the robust performance of the carbide grade and surface treatment with an early double margin support that enhances coaxiality to deliver the desired bore size and roundness. The drill is suitable for holes from 5xD upwards.
In terms of design, support chamfers are included to ensure running smoothness, while polished flutes reduce heat input and support the fast evacuation of chips. Additionally, the point geometry is protected by a negative chamfer, which makes the cutting edge robust and durable. Rounded edge preparation on the RT100XF produces a stable and efficient cutting edge; this rounding is produced with micron precision, something made possible by Guhring’s manufacturing competence.
Regarding workpiece materials, the through-coolant drills are suitable for structural and case-hardened steels, free-cutting and heat-treated steels, titanium, Inconel, Nimonic, and Hastelloy.
Offered in 5xD and 7xD, the drills can be purchased in diameters from 3 to 20 mm diameter, in 0.1 mm increments. The series is also available in all common imperial dimensions.

Available in the UK from Industrial Tooling Corporation (ITC) is the world’s smallest digital fine-boring head. Developed by company principal Big Kaiser, the EWE Downsize, also known as the EWE 04-7, aims to improve the machining process, making workpiece production safer, faster and simpler.

Ensuring compact dimensions, the EWE Downsize does not have its own display to show diameter adjustment. Instead, the device connects wirelessly via an app that has been specially developed by Big Kaiser for use on smartphones, tablets and smart watches. Capable of running on both iOS and Android operating systems, the external app simplifies the monitoring and configuration of fine-boring heads to make operators more efficient and reduce the risk of costly errors. Tolerance zones are indicated by changing colours on the display of the remote smart device.
EWE Downsize has a length of 26 mm and an outer diameter of 19.6 mm, which makes it suitable for machine tools with spindle sizes of ISO 20, HSK-E25 and larger. The head covers a diameter range of 0.4 to 7 mm, and allows infinite length adjustment of the tool holder and a maximum machining depth of 16 mm.
Big Kaiser’s head of R&D, José Fenollosa, says: “The EWE Downsize is the vanguard for future developments in the field of micro-machining, demonstrating the strength of our in-house development capabilities in both analogue and digital solutions. This boring head is just one of many new and innovative products developed and manufactured by Big Kaiser, positioning the company to grow with Industry 4.0 and the digital transformation of manufacturing.”

Framo Morat GmbH, a specialist in gear wheel and drive technology based in Baden Württemberg, is relying on grinding technology from Junker.

“We’ve been working with high-precision technology from Junker for a decade now,” confirms Alexander Denz, head of industrial engineering at Framo Morat. “As part of our growth strategy, we continue to develop our core skills – for cylindrical grinding operations we are much better positioned in terms of quality and process reliability. The two ‘Lean Selection’ high-speed grinding machines from Junker play a significant role in this.”
Junker’s two cylindrical grinding machines have proven their high speed in single or multiple-shift operations. Framo Morat wanted an economical and, above all, flexible machine concept which could fulfil all grinding assignments – from one-off production to the manufacture of small or large volumes. The machines are equipped with CBN grinding wheels and operate at peripheral speeds of up to 140 m/s. Some of the benefits of these machines include longer tool service life and extended dressing intervals.
“We grind diameters from 8 to 80 mm for shaft components with teeth, and component lengths of 40 to 460 mm,” says Denz. “Our production batch sizes range from 200 to 2000 workpieces per year. The new machines give us more flexibility with the peel grinding process, as opposed to grinding with corundum, as there is no need to change the grinding wheel between different workpieces.”
Notably, the high-speed grinding machines also deliver better quality by producing the entire outside contour in a single clamping set-up. The integrated measurement devices in the collar and longitudinal position are key control and monitoring systems during grinding.

Advanced Grinding Solutions (AGS) had no less than 10 of its machine manufacturing partners exhibiting at the recent EMO 2019 exhibition in Hanover: Rollomatic (tool grinders); Bahmuller and Tschudin (internal/external and centreless grinders); HandlingTech (automatic loading systems); Gerber and Magnetfinish (deburring machines); FLP (lapping and fine-grinding machines); Nova (external/internal grinders); Platit (coating machines); and Comat (filtration systems).

Rollomatic showed many tool grinders, including its six-axis 830XW for manufacturing large diameter cutting tools that has a novel combination of hydrostatic guides and linear motors for high levels of surface finish. Also of major interest was the Rollomatic LaserSmart 501 machine for machining PCD, CVD, and natural diamond tools. The 501’s machining speed is stated as being up to four times faster for processing multiple features such as cutting edges, chip breakers, and cylindrical lands in one operation. The machine has four cameras for complete and easy viewing of all laser operations. Rollomatic also used the show to debut its NP50 machine for the grinding of cutting-tool blanks.
Tschudin was exhibiting its latest ‘Cube’ grinder, which is stated as being the world’s smallest CNC centreless grinding machine, while HandlingTech displayed various loaders for machines, including its advanced palletZ and ecoZ models.
Platit exhibited its most flexible coating machine, the Pi 411 Plus, while Gerber focused on three brushing machines for deburring components, including the new Eco-Innovation, which received its worldwide debut.
