Angle Plates & Setup Blocks - Tooling, Jigs & Fixtures

Angle Plates & Setup Blocks

Ground angle plates and setup blocks that put a workpiece on a known plane.

Angle plates ground square on every face, so a part clamped to them is on a known plane. The squareness is what everything downstream measures from, so it is checked, not assumed.

What drives the price of this part

Derived from the callouts on this page. Where a driver is not on the drawing, it is not on this list.

Tolerance
Face flatness at 0.01 mm is the tightest callout this family carries. Tightening a callout is a process decision, not a machining decision: below the standard ±0.005 mm the work moves to grinding or jig boring, and the price moves with it.
Order size
Minimum order is 1 piece, so on a first order setup and programming are spread over very few parts and they are most of the price. Repeat orders at the same quantity are cheaper without anything on the drawing changing.
Certification and paperwork
ISO 9001:2015. On a certified family the inspection and documentation work is part of the price: first article inspection, material traceability and the dimensional report are produced per order, not per sample.

How these parts are inspected

Matched to the callouts above and the instruments actually on the floor.

  • Coordinate measuring machine (Zeiss CONTURA G2, two machines, GR&R 8.4% on the critical feature)
  • Dimensional report against the drawing, with a 100% check on critical features rather than a sample
  • Certificate of conformance and the mill certificate with every shipment

The full equipment list, with counts, is on the capability page; the inspection sequence is on quality and inspection.

Questions buyers ask

Why is cast iron preferred for a reference plate?
Because it is stable and it damps. Steel plates move as residual stress releases, and an angle plate that moves stops being a reference.
