Penta enhances inspection capabilities

Fareham-based CNC machining company, Penta Precision, has increased its measurement capabilities by investing in a Baty R400 shadowgraph profile projector supplied by Bowers Group.

In 2021, Penta Precision devoted significant investment into new, larger premises, as well as boosting its workforce and its capital equipment to include five-axis machine tools and the Baty R400 profile projector.

The R400 is used daily by the quality department for first-off checks and final batch inspections of CNC milled and turned parts, and by machinists to carry out in-process checks. Notably, the projector enables the company to measure a much wider range of parts due to the increased measuring range available when compared with the previous projector.

Penta Precision’s Baty R400 bench-mounted profile projector is suitable for both the shop floor and the standards room, combining high accuracy non-contact measurement with inspection with a large 300 x 150 mm measuring range. Offering a choice of digital readouts and optional automatic profile edge detection, the R400 ensures a projector that fits a wide range of requirements.

Mike Steppens, lead quality inspector at Penta Precision says: “We have a high mix of work, and so there are high demands on inspection. The R400 has helped to free up our CMM and prevent delays in first-off inspection. For the majority of the parts which can now be measured on the R400, we were having to use the CMM as the previous projector had too small a working window.”

The team at Penta are highly impressed with the Fusion software and its ease of use, with the ability to create a pictorial image of the part being measured.

Machine shop boosts production by 80%

Some years ago, ebbing oilfield business conditions spurred LeanWerks, based in Ogden, Utah, to pursue work in other industries (including aerospace and high-speed automation) to establish a more balanced customer base and steadier work flow.

Reid Leland, company president and co-founder, points to one example: an aluminium investment casting for a jet engine fuel filter housing. LeanWerks considered how it might take advantage of the milling capability of its Mazak Integrex i200S turn-mill to minimise the number of times the part is touched during machining. However, the part with its complex datum structure requires tight tolerances, including true-position tolerance of 0.25 mm on some widely separated features, and size tolerances of 0.01 mm and true position tolerances of 0.05 mm for other, less separated features.

To enable the effective machining of five faces of the investment casting in a single set-up, one of the measures adopted by LeanWerks was the integration of a touch-trigger probing system. As the turn-mill featured only one probing channel, LeanWerks retrofitted the machine with a Renishaw RMI-Q radio receiver and installed a PLC card in the main machine control panel to handle a second probe signal. The short probe uses a 25 mm long stylus, while the long probe uses a 50 mm long stylus mounted on a 200 mm extension. Both use a Renishaw RMP60 probe body.
The probing routines were programmed using Renishaw’s Inspection Plus software, and the resulting code was added to the machine program at the appropriate locations.

Alongside other measures, the process LeanWerks developed to machine this investment casting job on its turn-mill machine improved the production rate from 10 hours per part to less than two hours.

Industry urged to be COSHH compliant

A UK-based oil mist extraction expert is urging manufacturing and engineering companies to ensure they are COSHH compliant. Telford-based Filtermist Systems is making its customers and wider industry aware that the HSE is continuing to run its Fabricated Metals inspection programme. Inspectors are paying particular attention to exposure to metalworking fluids and welding fume, both of which can cause respiratory and skin conditions.

Craig Woodward, divisional sales director at Filtermist, says: “Despite COSHH regulations being introduced in 1989, we’re still seeing many companies who either don’t use local exhaust ventilation [LEV] at all, or don’t think they need it on every machine tool. However, LEV can lead to many benefits, including increased productivity, lower cleaning bills, consistent component quality and support in the recruitment and retention of employees.”

New capabilities for spring manufacturer

When Sertec made the decision to close its springs and wire forms division and put some assets up for sale, Emma Burgon, engineering director at Stalbridge-based William Hughes Ltd, spotted an opportunity to not only bolster her company’s existing capabilities, but introduce new ones.
“Because of the transfer of assets we’ve been able to increase our welding capacity, while we’ll also be adding a further four bending machines, taking us up to 10 in total. In addition, we’ve introduced a three-axis XYZ vertical machining centre and an EDM wire eroder, which we’re in the process of refurbishing. We’ve never had EDM capability before, but our tool-room manager is convinced that it will speed us up because it can pre-cut blocks prior to CNC milling. Our customers don’t normally give us very much time to make weld jigs, but if we can get off tools quicker than anybody else, we’ll win the project, so speed of weld jig design and manufacture is definitely a big plus.”

Strong 2021 for Mazak

The economic rebound from the Covid-19 lockdowns enabled Yamazaki Mazak to record a strong year for machine sales in 2021, including its highest monthly order intake across Europe in its history in October.

“The combination of a rebound in general subcontracting, strong sales in food and packaging, resilient yellow goods and agriculture sectors, and continued strong levels of investment from energy sector customers have all delivered outstanding sales growth,” says Alan Mucklow, managing director of UK sales, Eire and national distributors, who is cautiously optimistic about the year ahead. “The economic situation is not without challenges, but we’re expecting a rebound in aerospace and further growth in turnkey automation solutions to help machine users navigate the skills challenge.”
