THIS WEEK’S HIGHLIGHTS

Investments critical to future growth plans

Mills CNC, the exclusive distributor of DN Solutions’ (formerly Doosan) and Zayer machine tools in the UK and Ireland, has supplied subcontract specialist JTB Pressings with two new, FANUC-controlled CNC lathes.The machines, a 6”chuck/51mm bar capacity Lynx 2100LYSA and, a similarly sized Lynx 2100, are now in place at one of the company’s three production facilities in Willenhall.

Since their arrival, both lathes have been put through their paces machining, almost exclusively, a range of small, precision turned parts for JCB. These high-volume, short-cycle parts, include six individual components made from a range of materials that include steel, bronze andnylon.

JTB’s decision to invest in the two Doosan lathes was made to help the company increase the range of manufacturing services it provides to existing customers, as well as spearheading a drive to secure new business from different sectors.

Explains Ivan Evans, JTB’s managing director:“We are always looking to improve, diversify and grow.We did consider sliding-head as well as fixed-head models, but ultimately decided on the Lynx 2100 LSYA from Mills CNC owing to its compact size, proven reliability and multi-tasking capabilities.”

With both Lynx lathes’ capacity taken up machining parts for just one customer, JTB has now made the decision to invest further.

Says general manager Steve Lounds: “To free-up capacity on our Lynx machines we hope to invest in another two pre-owned Emi-Mec CNC lathes in the near future. These two-axis lathes will handle the high volume of turned parts currently machined on the Lynx lathes and, as a consequence, enable us to fully exploit the true potential of the Lynx machines and diversify our operations – as was originally intended.”

CGTech grows sales team

CGTech, the developer of VERICUT verification, simulation and optimisation software, has expanded its sales team. The internal promotion of Dave Woolams from technical support engineer to sales engineer, will ensure even better support for customers in the UK.In 2022, CGTech succeeded in growing its UK customer base, deeming it necessary to create an extra sales engineer position and take the team from five to six. The company has also recruited two new technical support engineers.

Woolams, who will cover Gloucestershire, Worcestershire, Bristol, Somerset, Dorset, Devon,Cornwall,Wales and Northern Ireland, says: “My responsibilities include sales and account management; looking at ways to help customers grow their business, as well as our own. Double-digit growth is always where CGTech wants to be in the UK. We achieved it in 2022, so it would be nice to do the same again this year.”

Transforming five-axis machine tool calibration

Renishaw has incorporated its new off-axis rotary measurement mode into the CARTO software suite, providing a single source for testing off-axis measurement using the XR20 rotary axis calibrator and XL-80 laser system. The latest release of CARTO, version 4.7, streamlines the measurement of rotary positioning accuracy for five-axis machine tools, where the XR20 rotary axis calibrator cannot always mount on the centre of rotation.

CARTO is a single software solution for Renishaw’s range of calibration products. Data collection takes place using the CARTO Capture application, while the CARTO Explore application is for data analysis. The new off-axis rotary measurement mode in CARTO Capture is a licensed option and allows the XR20 rotary axis calibrator, combined with the XL-80 laser system, to capture off-axis measurements in one session.

Dan Throup, product owner – calibration software, says: “A single test record is created in the CARTO database, significantly reducing the number of steps in the measurement process. This improved method gives greater data integrity and traceability from the Explore application to analyse the results. In addition, the Capture application now uses a new automatic sign detection move when capturing the angular errors associated with an off-axis test. This simplifies the process and reduces the chance of user error.”

First launched in 2012, the Renishaw XR20 rotary axis calibrator aids the direct measurement of rotary errors for stages, jigs and machine tools. The off-axis rotary measurement mode in the CARTO software suite provides a simple, accurate check for the alignment and positioning performance of rotary axes of any configuration.

Okuma announces green credentials

Since October 2022, production at Okuma’s three main machine tool factories in Japan has used only carbon-neutrally generated electricity, a goal achieved earlier than expected. The firm’s machining centres, CNC lathes and grinders are available in the UK and Ireland through sole agent NCMT.

Okuma also says that, from April this year, it will be labelling certain of its products ‘Green-Smart Machines’ if they are able to cut energy consumption considerably. These machines reducepower usage thanks to a trio of advanced technologies: the Thermo-Friendly Concept, whichnegates the need for a warm-up period; ECO Suite plus, which provides autonomous energy saving by monitoring spindle temperature and the pump; and systems for spindle cooling, which Okuma says reduce energy consumption by as much as 68% due to optimised control.

CADCAM suite adds new tool-making function

In the mould and die industry, Open Mind says that its hyperMILL CADCAM suite is regarded as a completeend-to-end solution as it can cover aspects such as electrode manufacturing and wire EDM. Now, it is the introduction of the five-axis radial machining function that takes centre stage.

The new function is suitable for the process-optimised production of round moulds, where surfaces cannot undergo hand finishing or polishing operations. For components such as blow moulds that are applied in vehicle bumper production or consumer goods bottles, high-quality machined surfaces are critical as secondary hand finishing can introduce optical facets and surface inconsistencies that may appear in downstream processing.

According to Open Mind, improvements to the current version of hyperMILL – combined with five-axis radial machining – are setting standards in blow-mould machining. Thanks to a new radial projection method, it is possible to calculate toolpaths extremely quickly, and the user can apply various machining strategies to respond flexibly to the component conditions.

The new ‘Flow Equidistant’ infeed strategy is the first of its kind that supports the generation of toolpaths with a constant infeed for vertical and challenging surfaces. This capability means that surfaces can integrate into the overall machining sequence, with processing taking place in a single step. Seamless machining with a very high surface quality is guaranteed, reports the company. Every machining sequence needs to produce sharp corners at the junction of the upper and lower halves of the mould to avoid problems during the moulding process. An automatic tangent extension feature eliminates the manual CAD steps needed to extend the numerous surface elements found in complex designs.
