Friction and wear-reduction technology

Applied Nano Surfaces (ANS) of Sweden has entered into a joint development programme with Sunnen that is focused on the patented ANS ‘Triboconditioning’ process, which is designed to reduce friction and wear on a variety of honed parts and components.

Chris Miltenberger, president and CEO of Sunnen, says: “ANS is at the leading edge of friction reduction technology. We’re excited about working with ANS on the development of new products and surface-finishing methods, which will bring unique solutions to all segments of the manufacturing industry.”
Triboconditioning is a combined mechanical/chemical surface-treatment process that uses a machining procedure to level off surface peaks and apply a friction- and wear-reducing compound to the component surface. Unlike spray coatings, the compound becomes an integrated part of the component structure at a nano level.
The process is mechanically simple and, in most cases, can be performed with Sunnen honing equipment. In addition, the process is said to be very cost-efficient in mass production environments, making it suitable for in-house manufacturing. Key applications include automotive engine components, such as valve train parts, cylinder liners, crankshafts and connecting rods, as well as industrial applications like hydraulic motors, rock drills, pumps, chains, gears and compressors.
“We’re looking forward to combining our knowledge of friction-reducing technology with Sunnen’s expertise in surface finishing,” says Christian Kolar, CEO at ANS. “The solutions under development have the potential to be real game-changers in component efficiency.”

Lapping gel for ball valves

Working closely with ball valve manufacturers, Engis UK has developed a lapping gel specifically for use in severe service ball valve lapping applications such as those found in oil and gas production and petrochemical refining.

Severe service ball valves are often installed in remote and difficult to access locations, and must withstand the harshest conditions, including high pressures, high temperatures and caustic materials, while providing tight tolerances and zero-leak characteristics.
Among the main benefits of Engis LD diamond gel is said to be a reduction in overall lapping times by up to 30-40%. In addition, less pressure is required using the LD gel, reducing scratching and operator fatigue in manual operations. This attribute results in less component scrappage, while test stand failures are significantly reduced – to near zero in some instances, reports the company.
The lapping gels contain specially controlled diamond particles that are micronised in Engis laboratories. In contrast, some conventional lapping compounds, particularly those not manufactured to the most exacting standards, incorporate rogue abrasive particles and can suffer from particle agglomeration or excessive ‘dry out’ during processing, resulting in surface scratches which compromise the zero-leak goal.
Engis LD gel is available in 18 or 100 g syringes in particle sizes ranging from 1 to 60 µm.

UK introduction for Comat with AGS

Advanced Grinding Solutions of Coventry has struck a partnership with the Italian filtration system manufacturer Comat.

Chris Boraston, MD at AGS, explains the rationale behind the new joint venture: “We’ve been importing a wide range of grinding and finishing machinery into the UK for decades, and have previously relied upon the choice of the machine builders that specify filtration units for their machines. This has worked reasonably well, but has proven to be problematic in recent years because either UK-based support for the filter units was non-existent or, if it was, we found it increasingly difficult to get good and fast support. This is because most UK-based distributors of filter systems are usually excluded from the purchasing process as filters are mostly bought turnkey directly from machine makers.”
It transpired that Rollomatic, which is AGS’ biggest agency and supplies many tool grinding machines into the UK every year, was working closely with Comat. AGS was therefore given excellent references for its systems and subsequently arranged to visit the company, which is based near Milan.
Comat manufactures super-filtration systems that deliver ≤2-3 μm filtration quality, making oil cleaner than new, unused oil. Importantly, this occurs throughout the entire working cycle, while minimising lifetime running costs and maintaining maximum coolant consistency.
Importantly for AGS and its UK end users, Comat filter systems use the company’s ‘Intelligent Performance Technology’, which allows remote monitoring in real-time during the manufacturing processes to ensure that optimum filtration quality is obtained at all times. Of course, remote diagnostics is part of this offer and overcomes most of the issues AGS had with other filter units. Furthermore, depending upon the model, the Comat filter units can be monitored, controlled and optimised by integrated controls, or externally by PCs, tablets or smartphones.

Gear-grinding centre installed

A leading European producer of helical and spur tooth pinion gears has selected a GTG2 gear-grinding centre from Holroyd Precision to test-grind a range of specialised gears and tooth forms.

Developed purposely for grinding precision spur and helical gears, worms, screws and rotors of up to 350 mm diameter and 160 mm gear face width, Holroyd GTG2 grinding centres use what is described as a unique machining system to achieve accuracy to DIN 2 levels and beyond.
Steven Benn, Holroyd’s regional sales director, says: “The customer required a machine capable of grinding a variety of gears to exacting tolerances. Products to be manufactured include spur and helical gears; gears with end tip relief and root fillet radius; worm tooth forms such as ZA, ZI, ZK and ZN; worms with sunken tooth forms; and dual lead forms with both cylindrical and tapered roots. The GTG2 was selected for its versatility, reliability and accuracy – the latter achieved through high levels of on-board machine intelligence and a machining process developed to compensate for helical twist.”
Helical Twist occurs when helical gears are ‘lead crowned’ to improve meshing and reduce noise and wear. Lead crowning varies the amount of material removed from the flank of a tooth, across the face width, by causing the tool motion
to deviate from a true helix.
The problem is that ‘in-form’ grinding has the undesirable effect of causing the profile of the tooth flank to vary across the face. Particularly in high precision and low noise applications, this variation affects gear wheel performance by concentrating loads on particular areas of teeth during meshing.
GTG2 machines correct this problem by calculating and controlling additional motions of the wheel during the grinding operation using dedicated software written by Holroyd engineers.
