Recently, a new customer reached out to the team at Duval Precision Grinding for rotary surface grinding on aluminum plates for a vacuum chuck. Duval has many years of experience grinding non-ferrous materials and grinding vacuum chucks for clients, so we immediately recognized ourselves as a perfect fit for the job. It wasn’t a task without its challenges, but Duval used expertise, precision, and skill to overcome every last one of them.

The Challenges of Grinding Aluminum Parts

The customer provided detailed information in their drawing design which made their requirements and dimensions crystal clear. The diameter was to be around 12″ and the height, which was ground, was around 1″ +.0005 with a 16 micro-inch finish.

The challenge involved determining the optimal fixturing to hold the part in the machine. One of the most important things to understand about precision rotary grinding for aluminum parts is that it’s a far more delicate process than many people realize. Working with a malleable, non-ferrous material like aluminum requires a stable means of holding the workpiece to ensure accurate grinding without scratching or denting the surface. 

To overcome this challenge, we take several strong magnetic blocks and place them strategically to brace the piece in place. This means that the part in question is held securely throughout the grinding process without causing damage to the surface of the metal.

Precision Grinding Results That Speak For Themselves

Thanks to the detailed instructions provided by the client, and Duval team’s experience with grinding non-ferrous materials, we were able to turn those parts around in just four days, exceeding the customer’s expectations with a speedy turnaround time given the scope of the project required.

In the end, the client was delighted with the work— once again proving DPG to be a reliable precision grinding service provider that will go the extra mile to ensure our customers’ satisfaction.
