PTG Holroyd chooses gearboxes from Apex Dynamics

PTG Holroyd is using the APC and ADseries of high-torque, low-backlash planetary gearboxes from Apex Dynamics as part of its ultra-precise CNC helical rotor and gear grinding machines.

Gearboxes are an integral part of PTG Holroyd’s technology as they drive the machine’s axes, making precision key. The company had very specific requirements for output torque, accuracy and product dimensions, and was seeking the optimal gearbox solution. PTG Holroyd approached planetary gearbox specialist Apex Dynamics with a set of tight specifications for its helical grinding machines, which Apex was able to meet with its APC and AD series.

Working alongside PTG Holroyd’s engineers and design teams, Apex Dynamics UK identified the optimalsolutions for the machine tool manufacturer’s helical grinding machines.

The specific Apex Dynamics’ high precision planetary gearboxes best-suited to PTG Holroyd’s helical grinders were from the APC series of rotary flange style gearboxes (with 55:1 ratio) and the Apex AD series of compact gearboxes (with 50:1 ratio). Both product ranges deliver high torque, low backlash of less than 1 arc-minute and high levels of accuracy.

The APC series comes with a patented curvic coupling output, giving a high-concentricity, low run-out, high-torque, zero-backlash connection. Its case-hardened and ground gearing offers high accuracy and high wear resistance for the gear train and, by adding a fourth planetary gear, boosts torque capacity by up to 25%.

The compact, helical, one-piece planetary cage design of the Apex AD series provides PTG Holroyd with a range of benefits. These includea stiff and accurate rotating flange design that supports accuracy of less than 1 arc-minute,and a flange to flange distance as short as 70mm, making it capable of fitting into the smallest spaces.

GrindingHub will be bigger and more international

Five months before the event opens, it is already clear that the next GrindingHub will be bigger and more international. Some 375 companies from 28 countries have already secured a place at the trade fair for grinding technology, which will take place on 14-17 May 2024 in Stuttgart.

The increase in exhibitors from Asia is particularly impressive. The organiser has received just under 50 registrations so far. The first GrindingHub was still suffering from the after-effects of the pandemic, whereas freedom of travel today allows companies from all over the world to make their way to Stuttgart. This is particularly evident among the Chinese: the number of exhibitors from China has grown from four to 32. China is currently the largest national producer and largest market for grinding technology.

As another trend, more abrasives manufacturers will be represented in 2024 than at the launch event, for instance. The broad range on show – including everything from grinding machines themselves to appropriate software tools, process peripherals and measuring and testing systems – raises the appeal of the trade fair for users of grinding technology.

Martin Büsch, head of marketing for central Europe at Saint-Gobain Abrasives, says: “As far as we’re concerned, GrindingHub has established itself as the leading trade fair for grinding technology within a very short space of time. We therefore see it as an excellent and useful opportunity to engage with our customers, potential interested parties and top-class experts.”

Markus Heering, executive director at the VDW, adds: “The VDW will begin the layout planning shortly. We are delighted about having to open a fourth hall thanks to the increase in the number of exhibitors.”

Latest sharpening solutions for tool production

Sharpening specialist Vollmer used last month’s EMO exhibition in Hanover to present automated grinding, eroding and laser machines for manufacturing tools made of ultra-hard cutting materials such as PCD, CBN and carbide.

This year’s product highlight on the Vollmer stand was the VHybrid 260, which can grind and erode tools up to 100% in a single set-up. The VHybrid 260 features multi-level machining realised via two vertically arranged spindles, where the lower spindle is for both grinding and EDM. With the new V@dison booster solution, the VHybrid 260 achieves a surface quality of up to 0.05 µm Ra when eroding PCD tools.

Thanks to the digital application, it is possible to integrate EDMinto tool production as a complete manufacturing process. According to Vollmer, with the Vpulse EDM generator, users can even producemicro-tools with diameters of 0.5mm and smaller with high precision, performance and surface quality. High accuracy is deliverable via the integrated ‘Laser Check’ measuring system, which achieves required tolerances of ±2µm in fully automatic closed-loop machining.

Also in spotlight at EMO was the Vollmer VGrind 360S tool grinder, which again features the concept of multi-level machining. At the show, Vollmer focused on the machining of CBN tools and how tool manufacturers can use the machine to configure and equip their production, regardless of whether they manufacture special tools or produce tools in high volumes.

Using appropriate automation such as the new HP 170 pallet magazine, the HPR 250 free-arm robot or HC4 chain magazine, the VGrind 360S is suitable for unmanned machining around the clock. With the HP 170, customers can also opt to integrate optical detection of the cooling channels.
