Breton SpA's core business has been the production of stone processing machinery. When Breton decided to expand its product line, which is to increase the machine tool manufacturing business, they realized that this would place higher demands on their manufacturing accuracy. Nisau has introduced approximately 30 calibration and measurement equipment, including laser interferometers, rotary axis calibration devices, ballbars and trigger probes. Now, with Renishaw's expertise, Breton's high-speed five-axis CNC machining center series has successfully ranked among the world's leading products.

Renishaw technology assists Breton in calibrating production equipment and controlling product quality
background
　　 Breton SpA is headquartered in Castello di Godego, Italy. Since its inception in 1963, the company has come a long way. Breton initially focused on the design and manufacture of machinery for the processing of natural stone, and soon turned to a complete set of machinery for the processing of synthetic stone, which often contains 7% of polyester resin. In fact, the innovative material of polyester resin was invented by Breton and is the backbone of its many years of business development.
In the 1980s, Breton began producing CNC machines for the processing of marble, granite and synthetic slabs for kitchen countertops and bathrooms. In this special development period, the company developed the first five-axis machining system.

In the next decade, Breton used its expertise to diversify its business and began manufacturing high-speed CNC machining centers for the metal cutting industry. With a commitment to innovative technology and superior quality, the company has grown to become the industry's leading global manufacturer in just a few years. Breton's commitment to product quality is based on the full trust of Renishaw's technology: they are convinced that Renishaw's products can help ensure the precision of the production equipment and ensure that they produce high quality machine tools.
Prior to using Renishaw's latest technology, Breton used the ML10 laser system to measure the axis motion of CNC machine tools to compensate for linearity errors, and used another supplier's laser system to capture the straightness data of the machine tool guides. Pre-calibration. However, Breton encountered some problems when measuring machine axes longer than four meters—inconsistent measurement data.

challenge
　　 From stone processing to metal processing, it is necessary to greatly improve the processing accuracy. Samuele Salvalaggio of the Sales Engineering Department introduced how Breton's own production equipment and the machine tools it produces follow the same quality control and calibration procedures in production practice.
“If a precision machine component is not produced by another precision machine, then you can't say that you are producing precision machinery,†he said. “Our quality control process actually consists of three phases: linear control, Axis motion checks and overall control of the motion mechanism, all of which are performed using Renishaw products."

solution
　　 Breston's range of Renishaw products including laser interferometers, rotary axis calibration devices, ballbar systems and touch-trigger probes are used in many of Breton's internal quality inspection departments and technical support departments.
When a machine is assembled, Breton uses the XL-80 laser calibration system to test the machine's positioning, linearity, and angular errors. These quality control measures are performed on all machines manufactured by Breton. In addition, Breton performs this type of inspection on all production equipment every year, and repeats the test once accuracy deviations are discovered. After Breton used other suppliers' systems to detect machine axes longer than four meters and encountered inconsistencies in test data, they chose the XL-80 system because the system did not have such problems.
Renishaw's XR20-W rotary axis calibration device is used to check the rotary axis error. "Now we use Renishaw's XR20-W rotary axis calibration device to perform the rotary axis test. The results are much better than in the past because XR20- W uses a reliable interferometric method that is different from the test methods we used in the past. Renishaw's technical support and professional services have played an important role in helping us achieve quality control goals,†said Samuele Salvalaggio.

With Renishaw's QC20-W ballbar system, Breton also ensures rigorous quality control testing of machine axis accuracy. The QC20-W is used to quantify the perpendicularity between every two linear axes and to quickly detect the basic positioning performance of the machine.
When the maintenance department colleagues used the ballbar to perform regular inspections, they couldn't help but praise the ease of use and accuracy of the system, so QC20-W also became the standard tool for all quality control and calibration departments in the company. .
In addition, this is the first check that needs to be performed on the machine when providing on-site technical support to the customer. In Breton's 40,000-square-meter facility, inspection of the three linear axes of the production machining center has also become a fixed working procedure. The operator can check the condition of the machine in just 20 minutes and prevent possible machining errors. The company now uses the ballbar system to calibrate production equipment, and externally provides technical support to customers, especially when customers encounter machine collision problems, they can use the ballbar to test.
result
　　 Breton currently employs approximately 700 people and its core business is still manufactured for stone processing machinery; although the manufacturing accuracy requirements for such machines are lower than machine tool manufacturing requirements, the benefits of calibration are already evident. All natural/synthetic stone processing machines produced by Breton are now calibrated using Renishaw products to ensure optimum performance.
