Precision machinist invests in Wenzel CMM

Subcontract machining specialist Barth Präzisionstechnik offers a broad component manufacturing capability range from 5 to 2500 mm, and from 5 g to over 2 tonnes. Serving customers in industries such as energy, construction and mechanical engineering, the company’s philosophy is based on maximum precision, a zero-defect mentality and absolute adherence to deadlines.

In keeping with this tradition of continuous quality optimisation, the Binzwang-based company opted for an LH 2015 CMM from Wenzel. The LH 2015 gantry measuring machine features WM Quartis software and the Revo five-axis multi-sensor probe system from Renishaw. The latter offers a combination of contact measurement and scanning, which enables fast and precise measurement of even complex components. Due to its high flexibility and accuracy, the combination of the Revo with the LH 2015 opens up considerable advantages and a wide range of possible applications.

WM Quartis software forms the heart of the measurement solution and enables the precise recording, analysis and visualisation of measurement data. Thanks to its intuitive user interface and versatile functions, Wenzel says the tried-and-tested measurement software is an indispensable tool for quality control.

The professional team at Wenzel supported Barth with the integration of the LH 2015, resulting in a smooth commissioning process. The machine enables the company to optimise its production processes and deliver first-class products to its customers.

The three generations of the Barth family currently actively involved in the business are unanimous: “Manufactured by a German family business for use at a German family business that handles high-precision measuring tasks, this measuring machine is not only sustainable for our company today, but also represents pioneering technology for future generations.”

Better on-site calibration with new capabilities

Calibrationhouse, a provider of UKAS-accredited calibration services, is commencing a £500,000 investment in an extensive suite of new capabilities to streamline and enhance equipment calibration for the manufacturing industry. The new services are set to offer a one-stop shop for calibration needs as it is possible to perform the majority of them at customer premises.

In 2023, Calibrationhouse rolled out new calibration capabilities including bore gauges, verniers, micrometers, height gauges, thermal imaging cameras and torque wrenches. The company also introduced inclinometer, protractor and expanded temperature calibration capabilities. This year, the company will offer calibration of force gauges, current transformers, high-pressure gauges, liquid flow, mass, gauge blocks and humidity devices.

A key advantage for manufacturers is the ability of Calibrationhouse to calibrate a wide range of equipment on-site, reducing lead times and equipment downtime.

Calibrationhouse’s engineers can deliver calibration services directly at customer premises, meaning crucial test equipment is unavailable for minutes rather than days. Alternatively, manufacturers can opt to send their equipment to Calibrationhouse’s base in Peterlee for back-to-base calibration completed within five working days from receipt.

Andrew Simpson, manager of Calibrationhouse, said: “We’re providing a comprehensive calibration solution of the highest quality that enables us to calibrate almost all of our customers test equipment, as recognised by our continuous accreditation as an approved vendor for the prestigious UK defence sector [JOSCAR]. Traditionally, manufacturers had to rely on multiple calibration companies who could each only handle a portion of their calibration needs. Our expanded capabilities mean manufacturers can now turn to Calibrationhouse as a one-stop shop.”

Renishaw launches RMP24-micro probe

Renishaw says its new RMP24-micro is the world’s smallest wireless probe for machine tools. The RMP24-micro measures just 24 mm in diameter and 31.4 mm in length. Despite its small form factor, the probe delivers measurement repeatability of 0.35 µm 2σ, which according to the company sets a new standard for wireless probes in this size category.

The micro-kinematic mechanism within the probe promotes ultra-low trigger forces, ensuring gentle contact with workpieces during probing. This capability not only minimises the risk of damage, but also reduces part deflection for enhanced measurement accuracy.

Designed for compact machines that manufacture high-value, high-precision components, the RMP24-micro is suited to applications in industries that include medical, dental, watchmaking and micro-mechanics. Tight measurement tolerances are easily achievable with the probe’s repeatability and lobing performance, while its short length and radio communication makes the RMP24-micro useable in confined spaces.

The probe uses Renishaw’s updated radio transmission protocol to communicate with the machine tool controller via the RMI-QE radio interface. With an operating range of up to 5 m, it employs a 2.4 GHz FHSS protocol, compliant with radio regulations worldwide. This FHSS technology has excellent power efficiency and allows the probe to co-exist harmoniously with other radio sources such as Wi-Fi, Bluetooth and microwaves.

Will Fenn, product marketing engineer for Renishaw’s Machine Tool Products Division, expresses his enthusiasm for the RMP24-micro: “Since we first previewed the product at the EMO exhibition in Hanover last year we’ve had an overwhelmingly positive reaction from the market. We’re now delighted to announce the full release of RMP24-micro and eagerly await showcasing it at upcoming exhibitions throughout 2024 and beyond.”

Thread gauges aid custom race car solution

Bowers Group’s precision measurement expertise played a crucial role in supporting the University of Wolverhampton Racing Team (UWR) with the manufacture of an adaptor plate. Used by OEMs such as Morgan, Mini and Toyota, adaptor plates convert the standard oil heat exchanger on the BMW B48 variant engine into an external oil cooler system. To ensure the accurate measurements of critical components, Bowers Group supplied an XT3 Holematic thread gauge, aiding UWR in achieving optimal performance.

UWR and the Morgan Motor Company were in an ongoing partnership to help convert two CX platform Plus 4 cars from road production vehicles into racing cars. The UWR team scheduled track test days to gather performance data on the new racing cars, where they discovered high engine and oil temperatures that could impact performance.

After exploring additional venting options that did not provide the desired impact, UWR designed an adaptor plate to replace the standard heat exchanger on the oil filter housing. This plate would enable the installation of an external oil cooler system, which was much better suited to lower both oil and engine temperatures in unison.

The team sought assistance from its partners and sponsors, including Bowers Group, Quickgrind, and Tungaloy UK, for the tooling and manufacturing of the plate. With time critical to resolve the issue as quickly as possible, Bowers Group promptly supplied an XT3 Holematic thread gauge to test the connections of the adaptor plate and ensure the team could build it accurately. Precision measurement was crucial for plate, which acts as a fluid barrier and pathway for both oil and engine coolant.

Extra stability for portable measuring arms

All 34 portable measuring arms offered in six-axis touch-probing and seven-axis multi-sensor variants by LK Metrology, are now available as standard with a 4.5-inch diameter mounting ring that allows the unit to sit on a larger base (3.5-inch ring previously). The new Version 3 Freedom arms are subsequently capable of measuring to higher precision. LK can supply a mounting ring adapter if an existing user already owns an LK tripod or stand with a 3.5-inch mount. Mechanical, magnetic and vacuum fixing alternatives are available.

As previously, the latest mobile metrology solutions feature a lightweight carbon-fibre tubular construction. Position feedback arrives courtesy of absolute rather than incremental rotary encoders, with the arms available in three accuracy categories: Classic, Select and Ultimate. Each is now capable of significantly higher accuracy measurement of size, position and form, whether using a tactile probe or laser scanner. Probing accuracy carries certification to ISO 10360-12 with functionality guaranteed up to 40°C.

The work-hardened six-axis arms offer full IP54 protection from water splashes and the ingress of dust and particles, delivering reliable, repeatable 3D inspection and measurement in harsh industrial environments. Also provided is enhanced RDS v6.4 software running on Windows for communicating with the arm via Wi-Fi or USB. The software offers improved monitoring of parameters such as ambient temperature and stress on the articulated joints, as well as base vibration, displacement, tilt and inclination.

The seven-axis Freedom Arm v3 does not offer IP54 protection but is able to deploy a laser scanner and a tactile probe to enable multi-sensor metrology. An OLED touch-screen display provides the operator with convenient fingertip control, raising inspection productivity by avoiding having to go back and forth between the arm and a computer.
