CMA tech presents the new one
ball grinding for series valves

Diamante - grinding machine

The series valve ball grinding machines DIAMANTE they were designed for machining balls with metal-to-metal sealing and coated in hard material or CBN.

The grinding tool cup can accommodate both abrasive stones and diamond pads and has been designed to process the widest range of spheres possible with the same cup.

All models are equipped with a SIEMENS 840 D CNC and are equipped with a RENISHAW probe for the fastest cup/ball centering operation.
The largest version can process spheres of ø2400 mm.

Our goal is to create technological solutions at the service of companies to optimize their production processes and their product.
We establish solid relationships with our partners by designing and implementing their ideas with extremely personalized and tailor-made support, trying to offer advantageous technical solutions.

Our machines are customized in consideration of the Customer's requests, which is possible thanks to the skills and experience of our Technical Office.
We are also able to make the 100% mechanical parts in-house at our machine tool department.
The complete assembly of the DIAMANTE is carried out in our workshop, then a team of specialized technicians takes care of the installation at the end customer.

The course is held by one of our electronic technicians and has the aim of instructing the customer on the correct use of the machine.
During this course, machining tests are also carried out on sample pieces.

Technical features

Chucks

the ball drive spindle has been designed to have maximum precision on
machining (roundness 0.01 mm) and motorized with a 70 kW Torque type motor, in the DIAMANTE 64" version, to guarantee maximum torque at low rpm.
The DIAMANTE 24" and 40" versions are equipped with a SIEMENS brushless motor.
The chuck is equipped with a universal gripping system designed to guarantee the workability of all types of spheres.
The cup holder spindle is mounted on an inclined and controlled axis (stroke ± 5 mm) to allow optimal cup/ball centering.

Grinding cup

the grinding tool holder cup has been designed to work the most with the same tool holder
wide range of valves. The tool is mounted on an adjustable stand.
The cup can be equipped with diamond pads or abrasive stones. It was designed with an extremely rigid structure which, during processing, allows obtaining roughness of less than Ra 0.2 mm.

Tailstock

designed to guarantee maximum rigidity and precision during processing, it is equipped with a hydraulic compensation system, controlled by CNC.
