Made by JUARISTI, promise of reliability

One of JUARISTI’s most important hallmarks is its integral production philosophy. Conscious of how essential it is that all components and accessories are harmoniously integrated in machining solutions to guarantee the reliability and precision of the whole, the company has always sought to manufacture and assemble all structural components, tables, heads and automation systems that make up its machines in-house.

To consolidate this strategy and increase the quantity and quality of its own production, JUARISTI has invested heavily in a cutting-edge manufacturing center: the new Accuracy Cube. The new space occupies more than 1,200 m2 in the JUARISTI facilities and consists of a critical parts machining area, a dimensional verification room and a laboratory for head assembly.

The ensemble will be operational by the end of 2019 and has required an investment of more than 4 million euros. It is equipped with some of the most advanced systems on the market, including a multitasking machining center, two grinding machines and a high-precision three-dimensional machine.

In addition, it will be the place where all data is collected and analysed to constantly improve the Accuracy Best+ process: the state-of-the-art production method developed by JUARISTI to ensure a precise fit before and after assembly. The space has been designed to ensure that JUARISTI’s solutions meet all customer needs.

Precision Parts Center

The Precision Parts Center is a space dedicated to critical parts machining. It has been equipped with a high performance TH3 Jig Borer manufactured by JUARISTI and several top-of-therange grinding machines. These equipment guarantee perfect finishes on all critical components of our customers’ products, resulting in greater accuracy and reliability.

The TH3 Jig Borer is specially designed to ensure thermal stability and maximum precision in the pieces to be machined. It has technical details that make it an especially precise solution. RAM components, head bodies, etc. are machined on this machine.

The grinding units have the capacity to grind parts of up to 600 mm in diameter and 4,000 mm in length, carrying out both external and internal grinding operations. The latest purchased unit also enables threads and angles to be made, is capable of measuring in-progress pieces and is prepared for deep internal grinding. The aim of these new equipment is to extract maximum precision and productivity. A great deal of work has been done to improve the grinding process, drawing on years of experience, developing the right tools and looking for the best process properties to achieve the highest accuracy. Precision boring and grinding processes are built into our Accuracy Best+ quality process: the Jig Borer and grinders are connected in real-time to measuring machines and assembly units for maximum accuracy.

3D Verification Lab

El segundo espacio del Accuracy Cube está destinado a las verificaciones dimensionales. Estará equipado con una gran máquina de medición de coordenadas (CMM) de la marca Zeiss. Se trata de la más precisa del mercado para grandes volúmenes (logrando precisiones de 3-5 micras en volúmenes completos y menos de μm en 1 m.

The second area of the Accuracy Cube is dedicated to dimensional verifications. It is equipped with a large Zeiss coordinate measuring machine (CMM), the most accurate for this volume of work (achieving 3-5 μm accuracies in full volumes and less than 1 μm in small parts).

This equipment allows measurements to be made on parts up to 6,000 x 3,000 x 2,000 mm. It will be used to verify the geometry of all parts prior to assembly, achieving full tracking of components and a comprehensive quality control.

The White Room

The last area of the Accuracy Cube will be used for high precision mechanical assembly. It is a white room free of impurities and equipped with the most advanced production means to guarantee optimum assembly of precision mechanical units such as milling heads. The temperature inside is kept at 20ºC.

In a space adjacent to the White Room, we have a test bench where the milling heads are subjected to load cycles to ensure that the assembly’s end result has been successful.
