Parts 2 clean: new solutions and know-how

Companies from every sphere of industrial manufacturing need to improve their product quality and cost efficiency on a continuous basis, while simultaneously cutting down on the consumption of energy and resources. Here, optimal and bespoke cleaning processes can provide a significant contribution, making a trip to the 20th edition of the Parts2clean exhibition essential. The show will take place on 26-28 September 2023 at the Stuttgart Exhibition Centre.

Whether it involves degreasing, classic component cleaning or high-purity applications – as varied as those tasks may be – technological and social trends are introducing new requirements to parts cleaning. In order to offer competitive products in the long run, cleaning must also be as economical, energy-efficient and resource-efficient as possible. In a growing number of cases, the stability of the cleaning processes must also be verifiable.

“As the world’s foremost information and procurement platform for industrial cleaning technology, Parts2clean offers ideas, solutions and services for adapting all of the steps involved in parts and surface cleaning to meet this increased set of demands and make them future-proof,” explains Christoph Nowak, project director at the Deutsche Messe group of companies. “In the same vein, effective knowledge transfer for parts cleaning that meets these requirements and is both process-secure and sustainable is the focus of the supporting programme.”

One proof of this is the presence of practically all market and technology-leading companies from the industrial cleaning technology sector at the event.

“Many of these exhibitors will be using the anniversary edition to introduce new and refined products and services to an international trade audience,” reports Nowak. This includes new system concepts for degreasing and classic cleaning tasks, as well as for precision cleaning and high-purity applications.

OSG UK adds another Walter tool grinder

The success of tooling specialist OSG UK continues apace, with the company recently installing another Walter Helitronic tool grinder to meet rising monthly volumes of tool regrinds and orders for new tooling, and to satisfy plans for its latest range of carbide tooling. These tools are joining the company’s own-brand series of taps, thread mills and end mills, as well as drills and reamers.

Supplied by Walter Ewag UK the company’s latest Walter Helitronic, a Power 400, joins existing Helitronic tool grinders and Helicheck Pro tool measuring machine at OSG‘s Basildon site. The ongoing investment by OSG means the company is “superbly equipped to meet all current and immediate future demands”, says director Tony Cooper.

Importantly, the fact that all of OSG’s Helitronic machines have pallet systems and robot loaders makes it possible to pre-load variable size batches of tools ready for effective and efficient processing overnight, unmanned, in batches of up to 30-off. The company says this capability provides the ultimate in order responsiveness for a wide customer base, including aerospace and automotive clients throughout the UK, Ireland and mainland Europe.

The multi-axis Helitronic Power 400 features a mineral cast machine bed and gantry design, and it provides 26 kW (up to 24,000 rpm) of spindle power. Coupled with sophisticated drive technology and X, Y and Z axis travels of 650, 350 and 720 mm, respectively, the machine can handle tools of 3 to 315 mm diameter, up to 520 mm long and weighing up to 50 kg.The robot loader can accommodate tools up to 125 mm diameter and weighing 5 kg.

Electron Engineering chooses Apex gearboxes

When Electron Engineering Services,a machine tool company specialising in machine refurbishment and CNC retrofitting, was retrofitting a grinding machine to turn it into an accurate grinder by installing servo systems instead of hydraulics, the company turned to Apex Dynamics and its range of precision planetary gearboxes. Electron selected AB115 and the PAII115 gearboxes for their high precision, hightorque and competitive price.

As part of the project, Electron determined that it needed a precision planetary gearbox fitted to the servo in order to get more accurate performance from the grinding machine and higher torque from a smaller motor.Good availability of parts was essential for timely delivery of the final machine design as Electron had previously encountered problems with other components as a result of supply chain shortages. Other key considerations included high levels of customer support, availability of 3D models for design, and assistance with calculations, in order to meet the project deadlines.

The AB115 is part of Apex Dynamics’ highest precision, highest torque range, while the compact, lightweight PAII115 is an economy precision planetary gearbox with accuracy of less than 6 arc-minutes and reduced backlash.

By installing in-line planetary gearboxes on servo axes, Electron was able to use a much smaller motor in the grinding machine to get similar torque and thrust, with lower backlash and quieter operation.

Phillip Denison, senior mechanical designer at Electron Engineering Services, says: “Having used Apex Dynamics products for some time now, they are really good at what they do and they understand what we do, helping when needed with things like calculations and 3D models. We were really pleased with the levels of service for this project.”

Grinding range elevates safety and performance

Fein is now offering a new grinding product range, revealing new safety and performance features to meet the latest user needs. Following the launch, power tool operators working across disciplines will be able to choose from the extended range of over 40 grinding tools, with corded and cordless options available. The range arrives as a result of first-hand industry feedback, to provide a product suitable for every application, including angle grinding, die grinding and stainless-steel processing, for example.

The portfolio includes the launch of the CG 15 compact angle grinder, the first of its class to feature a fully encapsulated, brushless Fein PowerDrive motor. The tool’s 1500 W motor and notable power-to-weight ratio allow user to operate with efficiency and endurance, reports Fein. Furthermore, the angle grinder requires fewer wearing parts, has longer service intervals and incurs lower maintenance costs throughout its life.

Fein’s new CG 15 grinder also offers users extensive protection through a variety of safety features driven by user feedback, including restart protection, kick-back check, jam monitoring and an efficient brake which brings the tool to a stop in less than 2 seconds.

Another tool in the range is the Protago high-safety angle grinder, created in collaboration to set new safety standards in the industry. Bouygues, the construction giant, had previously banned the use of compact angle grinders following a serious accident. However, together with Fein, the teams developed the Protago with safety features that almost fully eliminate the serious risks associated with improper operation.

The Protago, in addition to nine other tools in this launch, is now available on the 18 V AMPShare battery platform, powered by Bosch.
