A well-established manufacturer of heavy-duty lathes and mills based in Gipuzkoa, Spain, BOST Machine Tools Co (BOST) is reducing machine set-up time by 50% and improving rotary axis accuracy with Renishaw’s XR20-W rotary axis calibrator and off-axis rotary software.

With an increasingly demanding market, BOST was facing the need to verify and improve the precision of rotary axes – the primary challenge being the calibration of rotary B axes. B-axis calibration is critical in five-axis machine performance verification to maintain quality, but due to the design of the rotary heads, it was not possible to mount equipment at the centre of these axes to confirm performance. BOST also wanted to improve the performance of C axes, which the company measured previously using a pentaprism system. This method offered no measurement flexibility; a 360° test is limited to capturing 12 positions at 30° intervals.

Renishaw engineers demonstrated the XR20-W rotary axis calibrator on various machines at BOST. The XR20-W offered complete flexibility with test method set-up. It became possible to configure tests with capture intervals and measurement ranges to suit the requirements of the axis in question. Furthermore, Renishaw’s off-axis rotary software allowed BOST to mount the XR20-W away from the centre of axis rotation, providing a simple solution for the calibration of rotary B axes. In fact, this flexibility enabled the company to see improvements in specification for both rotary B and C axes.

BOST decided to purchase the XR20-W rotary axis calibrator as it offered the best five-axis calibration solution for its requirements. When used in conjunction with the company’s existing XL-80 laser interferometer it provides high accuracy of ±1 arc seconds, easy set-up, and fast data capture.

Additive manufacturing and machining engineers at the National Manufacturing Institute Scotland (NMIS) have created a low-cost remanufacturing solution that can extend the life of components by 120%, helping UK manufacturers to embrace the circular economy, boost sustainability and save costs.

The two-year £1.2m DigiTool project was part-funded by Innovate UK and focused on the remanufacture of dies, which are commonly used across the hot forging, stamp and press, moulding, and oil and gas industries to shape metal during production, but are typically subject to high costs and long lead times. The framework incorporates a three-stage remanufacturing process using a hybrid platform that combines additive manufacturing and machining. It can also be retrofitted to a legacy machine tool to save entry costs.

The Nuclear AMRC will work with Rolls-Royce on the next phase of its small modular reactor (SMR) development programme, and help prepare critical components for commercial production in the UK. In unison, the pair will develop the manufacturing capability for a variety of advanced processes, using the state-of-the-art machining, joining and testing facilities of the Nuclear AMRC’s research factory in Rotherham. The centre will also support the design of a new UK factory for large SMR components.

Following this development, the Nuclear AMRC will continue working with Rolls-Royce to create a fully integrated pre-production proving facility for SMR manufacturing. The proving facility will produce large-scale prototypes of the reactor pressure vessel and its closure head.

Hurco’s UK and Ireland subsidiary will stage its traditional Christmas open house at its High Wycombe headquarters on 7-8 December. Visitor numbers at these end-of-year events are always high because, in addition to having 12 machines cutting metal in the showroom, supply partners will exhibit for the first time since the start of the Covid-19 pandemic.

This year there will be 16 specialist stands covering tooling, work holding, CADCAM software, metrology, automation, mist extraction, rotary tables, angle heads and machine tool finance. As a result, visitors to the event will be able to discuss a wealth of auxiliary items to extract the best from their Hurco machine tools.
