Actuating tool with four inserts for stator bores

Actuating tools are the means of choice for creating turning geometries on machining centres. When it comes to machining stator bores on electric motors, tools with indexable inserts and fine boring tools were state-of-the-art until now. Mapal has developed a complex four-blade actuating tool to round off its solution portfolio for stator drilling.

With its solution, Mapal has come up with a highly productive machining process for the series production of stator housings used in electric motors. The solution offers productivity and precision as well as short cycle times with a process of three steps: pre-machining, semi-finishing and fine machining at machining diameters of more than 220 mm and with an HSK100 connection. A sophisticated actuating tool is part of the solution.

“With an actuating tool, the internal machining of the bore can be handled by a machining centre, which means turning is no longer necessary,” says Oliver Müller, customer service specialist at Mapal’s centre of competence for actuating tools. The entire machining process is thus executable with a single set-up. The only thing needed to use the actuating tool is a spindle with a drawbar – a so-called Uaxis in the machining centre.

“When it came to machining parts for electric cars, we were at our customers’ side with our tools from the very beginning,” says Müller.“Today, we help them to increase flexibility while machining the parts reliably and with short cycle times.” The actuating tool achieves more flexibility by ensuring both fast machining of varying contour trains in the bore and micron-level precision.

Strong sales at injection moulding machine specialist

Despite a difficult trading environment, Sumitomo (SHI) Demag Group, a specialist in all-electric injection moulding solutions, generated a sales turnover of €762m last year, aided by “substantial growth” in countries such as theCzech Republic, Hungary and Italy. This figure was only 6% lower than the historic accomplishments reported in 2021, when the group achieved its highest turnover to-date. CEO Gerd Liebig cites the dramatic impact of material availability and costs as the rationale for the sideways development, reporting that this inevitably had a negative effect on the company’s overall sales and profitability.

Business behind Covid memorial invests in youngsters

An engineering business behind a striking Covid-19 memorial is investing in young people as it looks to build a bright future.R.A.F Engineering, like many businesses, put its expansion plans on ice to ensure it could deal with the economic impact of Brexit, Covid-19, war in Ukraine and increased energy bills.Now, the Workington-based companyis setting its sights on the growth and diversification that itpreviously planned.

Rafal Gibki and Aneta Gibka took over the company, formerly Hudson Swan, five years ago, with ambitious plans to develop the business.They are already ahead of schedule on their revised plans after reaching a £1m turnover target in February 2023.“We’ve also continued to recruit young people and apprentices from Lakes College and trained them up ourselves,” says Gibka. “Rafal has a lot of engineering experience so young people and apprentices who come here are gaining expertise and knowledge that is standing them, and the business, in good stead.”

GrindingHub launchesdigital platform

Trade fair organizer VDW (German Machine Tool Builders’ Association), in co-operation with the IndustryArena business network, is now offers the grinding technology industry a top-tier platform under the 360°SPECIAL brand, even in the years when no trade fair is held. On 23 May 2023, companies will have the opportunity to pitch their new products and technologies to an international online audience and make contact with potential customers. The event will be presided over by an expert moderator and include scientific presentations on current topics.

Bystronic provides retail therapy for Crown

Founded in the late 1990s, Crown Manufacturing has evolved into a true manufacturing success story, overcoming adversity and growing to become a business with a presence at two locations in Somersetand a team of over 60 staff. Bystronic has travelled this journey with Crown Manufacturing almost since its inception.

Disaster struck the business in 2018 when a fire caught hold of the paint department, creating catastrophic damage. However, one thing that the fire did provide, was an opportunity to review processes, workflow and production equipment.

“The fire also gave us the realisation that we could work smarter with the people and suppliers that we have,” says Paul Read, works manager at Crown Manufacturing.

Since the fire, Crown Manufacturing has invested in three machines from Bystronic, the latest of which is a ByTube 130. This machine features a fully automatic set-up, bundle loading, six-axis control and high-speed and precision cutting that allows Crown Manufacturing to take on and efficiently complete high-quantity orders to a high standard.

“The tube laser takes away our dependency on a third-party supplier that we ended up struggling with,” states Read. “Integrating the ByTube 130 into our arsenal of machinery has been revolutionary, as it removes bottlenecks in the manufacturing process by allowing us to schedule and prioritise tube laser work in-line with due dates and urgency.”

In conclusion, Read says: “As much as the fire was a disaster, we bounced out of that to create far more productivity from being better organised. Having a new factory layout will help us to move onto the next level.”
