Gibbs Gears has recently installed a Klingelnberg Höfler CNC external/internal gear grinding machine at the company’s Stoke Mandeville headquarters.
The Klingelnberg Höfler Viper 500K will further expand the busy concern’s gear-grinding capacity and enable the production of complex gear geometries to high standards. Klingelnberg Höfler machines are available in the UK from Micronz.
Explaining the purchase, Paul Stevens, operational director, says: “The acquisition of the Klingelnberg Höfler Viper 500K gear grinder was prompted largely by our growing business within the Formula One, Formula E and other motorsport classes. It was also driven by a significant increase in business from the hypercar and aerospace sectors. The common denominators between all of these industries is their need for the highest standards of precision and quality, the technically challenging nature of the complex gear geometries they specify and their frequent requirement for fast delivery times.
“Due to increasing business with these demanding sectors, we recently undertook a search for a cutting-edge gear grinder,” he continues. “Although a couple of the technically advanced gear-grinding machines that we considered ticked some of our boxes, the only machine that delivered on all of our requirements was the Klingelnberg Höfler Viper 500K. It also helped our decision that many of our customers use Klingelnberg machines and have been delighted with their performance.
“Now fully operational, in addition to manufacturing gears with the demanding standards of precision and quality that we require, the Viper 500K has the speed of operation and quick change-over characteristics that are now improving productivity and reducing delivery times.”

Master Abrasives is introducing further machines to its showroom in Daventry having installed an Alex Machine Tools’ NH-500 surface grinding machine, which is new to the UK.
The demonstration area at Daventry was initially set up to show the range of Master precision grinding products, including conventional and superabrasive grinding wheels, diamond dressers and superfinishing products. Master-branded products will be available to support any in-house demonstrations and display the potential of both Micromatic, and now, Alex machines.
Alex Machine Tools, which is headquartered in India, offers a range of surface grinding machines, including a reciprocating hydraulically-operated model, a high-power rotary surface grinder, creep feed machines and a series of double-disk grinders. The machines can incorporate CNC, automatic in-process gauging and material handling automation, depending on the customer’s application and requirements.
Martin Stevens, Master Abrasives’ applications engineer, is fully conversant with the latest developments at Alex Machine Tools and the most recent progressions in technology. With a background in grinding applications engineering, Stevens has the technical expertise to help customers find the best solutions for their precision grinding needs.
Ian Meredith, applications engineering manager at Master Abrasives, says: “Now that the Alex surface grinder is installed, we are able to offer demonstrations and potentially grind customer parts when required. The demonstration machine will be a great aid in promoting Alex Machine Tools
across the UK.”

A standard brush-based machine for the deburring of complex engine components such as crankshafts and camshafts has been introduced by Kadia.
EC-Brush has five programmable axes, each with a rotary drive providing right/left rotation for the brush and the workpiece. The component is clamped against a point in a three-jaw chuck, with the brush rotating at about 500 rpm, and the part at 30 rpm.
Kadia’s EC-Brush features linear axes that provide the brush’s back/forward and lateral oscillation movement, and a traversing range for the centre. The latter enables different crankshaft/camshaft lengths to be clamped, so that any variant for three- to six-cylinder engines (for passenger cars or small commercial vehicles) can be deburred in any desired succession. Loading and unloading can be carried out manually, semi-automatically or fully automatically to suit requirements.
The brush, which is at the heart of the machine, is equipped with long and short fibres made of abrasive nylon. Only one operation is required, as the shaft is completely immersed in the brush. The long fibres reach from the cheeks up to the connecting rod bearings, while the short fibres deburr the main bearings area. Particles and flaky burrs, which typically occur during drilling or grinding, are reliably removed, says Kadia. A choice of fibre type allows adaptation to the component material. EC-Brush also permits wet machining.

Anca’s iView now enables single set-up cutting-tool manufacture through the semi-automatic measurement and compensation of profile tools, end mills and drills.
A newly developed camera bracket increases the measuring capabilities of iView to inspect a tool’s end face, and measure land widths, lip distances and chisel angles, without the need for camera commissioning or qualification.
“To remain competitive in tool manufacturing, more and more businesses are looking towards automation or semi-automation,” says Thomson Mathew, Anca’s software product manager. “Taking the time to set up the infrastructure smartly is delivering significant business advantages, such as improved productivity, better access to machine data and lower production costs.
Tooling manufacturers use iView to take an image of the ground tool using the camera and then compare the data with an ideal overlay profile generated by the iView software, without having to take the tool out of the grinder. This capability means faster set-up time and better accuracy, as the ground tool is checked against the tool requirements in one clamping.
Accurate to 0.002 mm, iView allows the accurate comparison and measurement of the actual cutting tool against the profile. The technology automatically compensates the tool and, based on the overlay and profile error, it is adjusted and re-ground. This process also eliminates any accuracy loss that can occur when tools are transferred between grinding and measuring machines.
One iView camera can be used across multiple machines in Anca’s MX, TX and GX/FastGrind range. The latest bracket assembly, which is suitable for new and retrofit applications, allows the iView camera to be mounted horizontally, inside machine.

After over 50 years of providing industry with mounted points supported by technical application advice, Master Abrasives has released a new mounted point brochure.
The brochure is designed with the Master brand’s updated look, and contains a selection guide on Master grade types for use on materials such as aluminium, cast iron and unhardened steel. A page for W, A and B shape points provides a list of standard sizes, drawings and a code relating to each item’s dimensions.
Managing director Paul Batson says: “Master Abrasives has come a long way since it was established over 50 years ago to sell mounted points to the UK market. Nevertheless, this product is still a core part of our product offering, and a major aspect where we can offer customers better productivity and improved results. Our message is that we will work with customers to find the best solution for their application, whether that’s a standard stock item or a specially developed design for the task in hand.”
Master Abrasives’ vitrified and resin mounted points are manufactured to high standards of concentricity, dimensional accuracy and stability, in tightly controlled formulas. They are used in the investment casting, tool and die, precision and heavy-duty fabrication industries for specialised and general deburring applications, in addition to maintenance-based operations. Master mounted points are suitable for difficult grinding and finishing applications involving alloyed and unalloyed steel, grey and nodular cast iron, stainless steel, aluminium, and exotic metals.
Mounted points are manufactured by Master Abrasives in a range of aluminium oxide, silicon carbide and ceramic aluminium oxide grades with a vitrified or resin bond. To suit different applications, the company also offers Masterflex, rubber, unitised, superabrasive nickel electroplated and felt grades.
