Precision aluminum plate FAQs

Q: What production equipment is needed for precision aluminum plates?

A: Chalco utilizes stable gantry milling machines with over 2 meters wide milling heads to create precision, accuracy, and unique surface characteristics. Each plate undergoes checks for thickness, flatness, and surface roughness, and is finally surface-protected with black and white films.

Q: How are tolerances achieved in precision aluminum plates?

A: Precision aluminum plates provided by Chalco adhere to very strict tolerance controls (± 0.002 inches), aiding in saving spindle time, simplifying clamping processes, and avoiding concerns about cutter taper and secondary operation fixtures.

Q: How does precision aluminum plate improve production efficiency?

A: Aluminum billets, after precision grinding, significantly enhance dimensions and accuracy, eliminating the need for adjustments to the parts before final machining, thereby improving the production rate or throughput of machining centers.

Q: What are the advantages of using precision aluminum plates?

A: Chalco's precision aluminum plates reduce setup and preparation time, eliminating the need for self-grinding, sawing, flattening, and squaring of blanks, significantly improving production efficiency and reducing labor costs.

Q: Are there processing standards for precision aluminum plates?

A: Chalco's precision processed aluminum cast plates meet high standards regarding thickness tolerance, flatness, parallelism, surface roughness, and give significant attention to basic values such as physical, metallurgical, and technical performance.
