Custom CNC Milled Fixture Plates

Detailed Description

Custom CNC milled fixture plates are precision tooling components used to locate, support and secure workpieces during machining, assembly, inspection or automated production. Common designs include machining fixture plates, modular tooling plates, inspection bases and assembly jigs.

Fixture plates are typically manufactured from 6061-T6, 7075 aluminum, tool steel or stainless steel, depending on required rigidity, wear resistance and production environment. CNC milling can create threaded hole grids, dowel-pin holes, locating pockets, reference slots and clamping interfaces according to the customer's fixture layout.

For production tooling, flatness, hole position and datum relationships are particularly important. Precision probing, reaming and coordinate inspection can be applied to critical mounting and locating features.

Available Surface Finishes

• Precision As-Machined: Maintains accurate tooling and locating surfaces.
• Clear Anodizing: Provides corrosion protection for aluminum tooling plates.
• Black Anodizing: Suitable for general industrial fixtures.
• Hard Anodizing: Recommended for frequently used fixture surfaces.
• Electroless Nickel Plating: Available where additional surface hardness is required.
• Grinding Finish: Can be specified for selected precision reference surfaces.

Structural & Functional Breakdown

• Threaded Hole Grid: Supports flexible clamps and modular tooling components.
• Dowel Pin Locations: Provide repeatable workpiece or fixture positioning.
• Reference Datum Edges: Establish consistent setup coordinates.
• Machined Locating Pockets: Secure parts with controlled orientation.
• Clamping Interfaces: Allow toggle clamps, stops and custom tooling to be installed.

Key Features

• Precision Hole Positioning: Supports repeatable machining and inspection setups.
• Controlled Flatness: Important for fixture stability and workpiece positioning.
• Custom Grid Patterns: Hole spacing can be produced according to customer requirements.
• Reusable Tooling Design: Suitable for modular and dedicated fixture systems.
• Wear-resistant Finishes: Hard anodizing and plating options extend fixture service life.
• Prototype & Production Fixtures: Suitable for R&D, pilot production and regular manufacturing.
