Three lathes acquired in five years

Based in Steinhagen, Germany, wastewater pump manufacturer Pentair Jung Pumpen, has invested in three CNC lathes from CMZ in the just five years, mainly for turning steel and cast-iron components.

“We have found the ideal partner in CMZ,” states managing director Stefan Sirges. “Just like at Jung Pumpen, for them, quality is a crucial element in the manufacturing of their lathes. Our third CNC lathe in just five years; I think that says it all. The whole package – the product, service and consultation – is excellent.”

The trio of CMZ CNC lathes at Pentair Jung Pumpen comprises TD-35-Y-1350, TC-30-Y-800 and TC-30-Y-800-L-servo+GL20II models.

Pentair Jung Pumpen started operations in 1924 when the business was founded by plumber Heinrich Jung in Steinhagen.” That humble plumbing business is now a premium manufacturer of wastewater pumps that employs over 350 people, with a yearly turnover of €78m. Since 2007 it has belonged to Pentair Plc, a global supplier of water technology solutions.

Quality is not just a cornerstone of business strategy, it is written into the company’s DNA and forms its main motto. When the moment came to renew its existing machine tools, quality was a non-negotiable condition for choosing a suitable partner.

Sirges admits that when he came across CMZ and learnt about the painstaking manufacturing process of the lathes in depth, his mind was made up. For customers such as Pentair Jung Pumpen, for which quality at every stage of the process is fundamental, this aspect is a deciding factor.

Vixen takes first Star SX-38 Type A

Star Micronics GB is reporting a high level of demand for its SX-38 Type A model, with the first UK machine ordered prior to its arrival from the factory.

The latest offering from Star – the SX series – represents years of machine-tool research and development to produce the next generation of sliding-head lathe technology.

For machining on the main spindle, the 12-axis SX-38 features a 10-station turret and an opposing four-station gang-type tool platen. In addition, the fully programmable swivelling B axis offers four driven tools for machining on the main and four counter spindles for the sub-spindle model. Mounted on an independent Z3 axis, the turret utilises Star’s quick-mount tool units, which maintains compatibility with existing models.

The very first of the new SX machines has been pre-ordered by Vixen CNC, a specialist supplier of mill-turn components located in Gwynedd. With 20 existing Star models on-site offering up to 42 mm diameter capacity, the acquisition of a new SX-38 further enhances its machine-tool portfolio and marks another significant milestone in the growth of the business.

Vixen CNC’s managing director Jake Wood says: “Remaining at the forefront of the turned-parts industry is of great importance, and our continued investment in the latest Star technology allows us to offer unparalleled response times, superior quality and full manufacturing flexibility.

“The SX-38 offers significant benefits and further increases our sliding-head capabilities,” he adds. “We work with a vast range of materials and supply finished parts to a wide array of sectors, including automotive, medical, marine and fasteners. Our new SX machine will give us the ability to explore additional business opportunities.”

Long association pays dividends

Established in 1982, Daventry-based Hi-Force is a UK specialist in hydraulic torque wrenches, bolt tensioners, jacks, crimpers and cutters, as well as nut splitters and flange spreaders.

Having previously subcontracted its component production, the company decided in 2008 to open its own machine shop and bring the majority of its metal cutting in-house.

The first machine-tool purchases were a five-axis machining centre and NL3000 lathes from DMG Mori, closely followed in 2010 by an NT 4250 turn-mill centre. Earlier this year the latter machine was replaced by a NTX 3000 seven-axis multi-tasking version. More than 80% of the 20 CNC machine tools on-site are from this supplier.

Chris Dickinson, group operations director, says: “The previous NT 4250 gave us remarkable service, but we thought it prudent to upgrade to the latest model from DMG Mori, which incorporates newer technology, provides greater flexibility and is more economical to run.”

The primary reason for buying the former turn-mill centre was for the production of aluminium housings used by higher torque tools in the Hi-Force product programme. However, the replacement machine is cutting a variety of materials, mainly aluminium but also alloy steels including EN24T and EN30B in an annealed condition. Some 100 tools in the magazine provide flexibility when setting up a new job, as the required cutters are normally already present.
The manufacturer’s relationship with this machine-tool supplier has grown over the years. Equipment from other suppliers has been considered along the way and, indeed, some has been purchased. However, for top-end production plant, Hi-Force has decided to standardise on DMG Mori due to the reliability of its machines and the quality of service.

TWP installs used sliding-head lathe

Despite starting out more than 25 years ago, Dudley-based TWP Manufacturing only opened its CNC machine shop at the beginning of 2019 to produce in-house most of the components needed for its proprietary products.

Vertical machining centres and a single-spindle, fixed-head bar auto are to be found on the shop floor, but in May 2020 the company bought its first sliding-head twin-spindle lathe, a 20-year-old Citizen Cincom M32 equipped with an Iemca Boss 432r bar feed. The machine was originally sold in 2000 by the Japanese manufacturer’s agent for the British and Irish markets, NC Engineering, which in 2008 became a wholly-owned subsidiary, Citizen Machinery UK.
Phil Stanley, a director of TWP Manufacturing, says: “The speed and surface finish we are achieving are just incredible, and the fact that there is no operator intervention means we’re able to implement lights-out production, which we are looking to do later this year.”

In the first few of months of operation, the Cincom M32 was devoted to large-volume production of one particular component, but another four part numbers have now been added. All are machined from 1” hexagonal steel bar, and annual production will exceed 200,000.

Pre-sales time studies and cutting trials carried out by Citizen Machinery UK showed that all five components could be produced within tolerance at the required speed. The calculations were performed following a visit by managing director Edward James and regional sales engineer Warren Garratt to the Dudley factory, during which the company was advised on how best to proceed with its in-house turned parts production strategy.

“Even though the machine was 20 years old and we bought it independently on the second-hand market, from the outset Citizen have been behind us,” says Stanley.

Tornos aids automotive fortunes

Identifying a business opportunity is one thing, but turning an opportunity into a profit centre is quite another. When the founder of Wuxi Fortune Technology decided to pursue manufacturing certification with one of the world’s largest automotive technology powerhouses, he chose Tornos as his partner for turning machines and the respective application and process support.

Managing director Jian Wang says: “We saw there was a place for high-end turned part production. To fulfil the great potential this opportunity represented we needed high-end, reliable and effective turning machines that would guarantee our ability to serve automotive customers. We knew that using advanced production equipment and technologies would help identify us as an excellent supplier, allowing Wuxi Fortune to deliver parts earlier than expected and even become an exclusive supplier of certain components.”

Jian Wang specifically wanted multi-spindle turning machines to gain higher efficiency and product consistency, while reducing manpower and production costs.

Wang visited and compared several turning machine manufacturers before purchasing from Tornos. Today, there are two MultiSwiss 6×14, one MultiSwiss 8×26, an SAS 16.6 and a MultiSigma 8×28 for small precision parts on site at Wuxi Fortune.

“Our Tornos machines are reliable and efficient,” he says. “Tornos provides completely integrated services, application knowledge, machine maintenance, training and spare parts to the Chinese market.”

Collaborating with Tornos helped pave the way for Wuxi Fortune to become the exclusive, worldwide supplier of a diesel injector pin shaft to a leading automotive technology player. The 23 mm long part has a maximum outer diameter of 9 mm and a minimum groove diameter of 1.3 mm, and requires a tolerance of ±0.03 mm on the outer diameter.
