CNC Machined Plates

Core Advantages

Room for Integrated Mounting Features

Plate thicknesses from 2–150 mm cover thin mounting members and substantial base sections. For a base containing recesses or fastening features at different levels, a thicker section provides material for those features without building the entire foundation from stacked spacer plates.

Clear Upper Mounting Surfaces

Counterbores recess the specified fastener heads below the working plane. On a tooling base that carries another plate or fixture above the joint, this leaves the intended mounting area clear of projecting heads and preserves the planned assembly envelope.

Wear-Resistant Aluminum Surfaces

Hard anodizing is available for aluminum plates. On exposed surfaces subject to repeated rubbing or handling, the oxide layer provides a harder wearing surface than bare aluminum, protecting the substrate at frequently contacted areas around the mounting assembly.

Customization Capabilities

Plates are manufactured from the released drawing or physical sample. Stock preparation and face machining establish the base references, followed by the required hole-making and edge operations; drawing-specified grinding is included in the process route where required.

Quality Control

Incoming stock is checked for grade, dimensions, hardness and surface condition. The inspection plan identifies the reference face and the machined features that establish the plate's position during measurement.
First-article and in-process checks cover the mounting plane and the relationships between the attachment features. CMM results are assessed against the drawing datums, while surface inspection identifies machining marks or raised edges on the intended seating areas.
Final inspection follows the completed machining and finishing route. Each plate is checked for key dimensions, coating condition where applicable and handling damage before packing, with the measurement record linked to the drawing revision and production lot.
