Toolmaker dives into cost savings with Guhring

As a family-run business, Canterbury Tools has been involved in the design and manufacture of press tools since it was established almost 50 years ago. To optimise the production of specialist press tools, the Walsall-based subcontract manufacturer utilises cutting tools supplied by Guhring. 

The company specialises in the production of single operation tools, progression tools, transfer tools, as well as components and assemblies for automated and robotic processes in sectors as diverse as agriculture and construction, through to medical, IT, aerospace and automotive.

Canterbury Tools is always looking for opportunities to accelerate performance and productivity. Josh Bennett, operations team leader, says: “When you are cutting materials like D2 tool steel and running intricate forms with a high material removal rate, you can burn through tools quite quickly.”

Based on an ethos of continuous improvement and progressive strategies, the company took notable steps forward after it was introduced to cutting tool manufacturerGuhring at the MACH 2022 exhibition.

“Our first Guhring tool was the Diver series of end mills,” says Bennett.“We trialled the tools and to our surprise they delivered three times the performance of the apparently high-end tooling we were using at the time. From this point onwards, we took Guhring seriously. We found we could increase our cutting depths and stepovers by 1 to 1.5 times and increase our speeds and feeds while achieving a much higher tool life.”

He adds: “With a much higher material removal rate, jobs are on machines for less time, which is massive in the world of CNC machining.Additionally,not having to change the cutters as often reduces the downtime incurred by tool changeovers.”

Ceratizit wins prestigious environmental award

Ceratizit has received the Prix de l’Environnement 2023 from Luxembourg industry association FEDIL for the process used to manufacture carbide grades in the upGRADE product family. By using secondary raw materials from an optimised recycling process, upGRADE carbide grades not only offer a particularly low carbon footprint, but also the high performance of a premium carbide grade.

“Mining ore containing tungsten at a content of 0.06%means it requires the transportation of around 200 tonnes of ore to obtain 1 tonne of metallic tungsten, which requires a lot of energy,” explains Dr Ralph Useldinger, head of group analytics and fundamental R&D. “This is why Ceratizit only uses secondary raw materials from the zinc recycling process for our upGRADE grades in order to minimise the carbon footprint of the products.”

The zinc deployed to break up the carbide structures is reused, meaning that the process produces emissions almost exclusively as a result of the necessary electricity. However, Ceratizit also scores points in this area: “Since the beginning of 2023, we’ve only been purchasing green electricity from sustainable sources,” saysexecutive board member Frank Thomé, who adds: “The upGRADE product family is an important component of our sustainability strategy. They prove that more sustainable carbide products are possible without having to compromise on performance.”

The upGRADE product portfolio currently includes the CT-GS20Y carbide grade for metalworking, which has already won the Best of Industry Award. It forms the vanguard of a product family that, according to Thomé, is set to become increasingly sustainable in the coming years: “Our goal is to be the leader in sustainability in the cemented carbide and cutting tool industry by 2025.”

Tungaloy adds more mini boring bars to range

Tungaloy is adding 146 new solid-carbide mini boring bars to its TinyMiniTurn series. The new mini bars are available in a wear- and fracture-resistant grade SH725, and with through-coolant.

TinyMiniTurn incorporates a variety of small-diameter boring tools, including solid-carbide mini boring bars for as small as 0.6 mm diameter boring and boring bars with a brazed CBN tip. The series also offers an indexable solution which comes with a tiny insert featuring an optimised pressed-in chipbreaker, enabling boring down to 5 mm diameter.

Tungaloy’s TinyMiniTurn solid-carbide miniboring bar line includes10 different geometry types for internal turning, profiling, grooving, deep facing and thread-turning operations. Furthermore, the JBBS-4N tool sleeve designed to hold TinyMiniTurn solid-carbide boring bars features four periphery coolant outlets situated on the tool periphery that direct the coolant to the optimal positions close to the cutting zone. This capability provides improved coolant supply and predictable tool life, reports the company.

The new solid-carbide mini boring bars are available in SH725 grade, a PVD-coated grade that Tungaloy says provides the boring bars with an excellent balance of wear and chipping resistance. In combination with through-coolant, the boring bars enable high-performance chip evacuation and long tool life. The use of JBBS-4N tool sleeve will further improve chip evacuation for minimum machine downtime by preventing chips from ‘bird nesting’ around the tool and workpiece, which is a common cause of machine stoppages.For further information www.tungaloy.com

Hole-making is no bore with new heads from ITC

Industrial Tooling Corporation (ITC) is further enhancing its portfolio of bore machining products with the expansion of the Big Kaiser EWN monoblock range. The ability to improve productivity and performance arrives thanks to the introduction of Big Kaiser’s Smart Damper technology, which reduces chatter and, subsequently, cycle times.

The EWN Monoblock fine boring heads now include the new CK1 and CK2 products for the machining of diameters from 20 to 36mm and 25 to 47mm, respectively. The full EWN monoblock family of products ranges from the smallest CK1 to the largest CK7,today supporting fine boring from 20mm to over 200mm in diameter.

The Smart Damper mechanism helps to absorb vibration, essentially eliminating chatter and thereby achieving higher levels of precision with superior surface finishes. Thanks to its inherently stiffer design, ITC says the Monoblock boring head ensures high precision even when machining long bores.

EWN Monoblock CK1 and CK2 heads do not have an interface, enabling users to achieve significantly tighter tolerances. A major advantage of Big Kaiser’s Smart Damper technology is that it eliminates the need to reduce cutting speedsin order to manage vibration. This categorically increases metal removal rates and raises productivity levels.

 
Giampaolo Roccatello, chief sales andmarketing officer for Europe at Big Kaiser, says: “These new boring heads are ideal for achieving deep, chatter-free boring in challenging materials. Together with our EWB and EWB-UP ranges, the EWN boring heads represent some of the most advanced and sophisticated tools available on the market.”

Mapal improves machining of axial piston parts

Mapal has carefully examined critical components of the fluid power industry and their potential for complete machining. An example is axial piston pumps and motors, a central component of which is the cylinder block, made either of steel (C45 or 42CrMoS4) or spheroidal cast iron (EN-GJS-500-7 or EN-GJL-400-15. Mapal experts have developed a solution that reduces the machining time for a customer’s cylinder blockby 19%.

“One customer was struggling with high costs for manufacturing cylinder blocks,” says Tobias Stolz, component manager for general machining at Mapal. “A great deal of effort was required to ensure the defined surfaces, which had to be between Rz = 27 and 37 µm, as well as the high quality of liners with tolerances for roundness, straightness and parallel alignment of 3 µm.”

The customer today machines the pressure and suction kidney with the Mapal OptiMill-Uni-Pocket solid-carbide milling cutter as part of a new process. This tool supports the boring operation by way of inclined plunging. The machining of these inlets and outlets therefore does not require any other tools.

A step drill with Tritan-Drill geometry offers similar benefits when pre-machining the piston bores, dispensing with the requirement for a spot face. Furthermore, thanks to sharp cutting edges, the bottom of the bore no longer requires deburring. The multi-stage Mapal fine-boring tool ensures optimal quality before pressing in the brass bush. It is not only very precise during machining but also particularly economical thanks to the HX insert’s six cutting edges. These three tools alone reduce machining time by 19% compared with the previous method.

“We offer our customers economical processing solutions to their machining challenges for all functionally relevant parts in the fluid power industry,” summarisesStolz.
