Steel Angle Plates for Machining & Milling

Machined Angle Plates

Machined Angle Plates

We manufacture non-standard, custom, and specialized steel angle plates for grinding machines, manual mills, and CNC machining centers.  Precision machined angle plates are used to clamp and to hold work-pieces in a precisely vertical, 90-degree position for precision boring, milling, drilling or otherwise machining in the vertical plane. Non-Standard Precision steel angles can be fabricated to within 0.005″ squareness per 4-foot linear side length, forming a nearly true vertical plane for machining large fabrications and plates. We cut A36 steel plate to size, stress relieve the parts, weld the pieces together, grind and machine these angles complete to your specifications at our shop. We machine T-slots, channels, grooves, and holes, and we can attach hand-holds and lifting chain ring attachments, when required. All of the angles to the right are manufactured from A36 plate and fabricated complete at our shop.

Large capacity precision grinding shops, machine shops, short-run steel part manufacturers and various job shops require custom steel angles built to 30°, 45°, 90°, and custom angular requirements. Whether you need precision ground angles, machined to close tolerances or to less critical tolerances, we can handle your order.

Large, Custom-Built Steel Angles

Larger than 24″ x 24″.

We fabricate machined angles to as large as 48″ x 96″ from whatever grade of steel you need, however you need them built.

Precision Grinding, Inc. specializes in manufacturing large, custom-sized angle plates that are used to machine large fabrications. We manufacture large angle fabrications, workpiece tombstones, jigs, fixtures and workholdings to your custom specifications. Small standard angle plates, small T-Slotted angle plates, small universal right angle irons, and small stacked boxed angles are usually cast to a standard size during large production runs by one of several angle manufacturers who manufacture standard sizes, smaller than 24″ x 24″.
