Block Tolerances

Microform Standard Manufacturing Block Tolerances

The following tolerances will be applied, unless otherwise specified prior to order. If looser tolerances are permissible, please notify your account representative — it may be to your price and/or lead time.

Laser Cutting

Laser cutting is well-suited for mild steel (including pre-plated steels like galvanized steel), stainless steel, and aluminum. Fiber optic laser cutting is the best choice for non-ferrous metals like brass and copper.

Feature Location +/- 0.005″
Hole Diameter +/- 0.005″

Waterjet Cutting

Materials that are too thick, or not conducive for laser cutting often fit well with waterjet cutting. A major advantage of waterjet cutting is that it does not produce Heat Affected Zones (HAZ).

Feature Location +/- 0.005″

Forming

CNC forming is a highly efficient and repeatable means of bending raw metal into parts through applied force. Forming is used in a wide variety of industries, including aerospace, automotive, architectural, construction, lighting, agricultural, machinery, and solar.

For Materials Up To 1/8″ Thick

Angle +/- 1°
Bend to Bend +/- 0.015″
Bend to Feature +/- 0.01″
Flange Length +/- 0.007″

For Materials Up To 1/2″ Thick

Angle +/- 1°
Bend to Bend +/- 0.03″
Bend to Feature +/- 0.015″

Weldments

Welding is a metal fabrication process that joins metal components by using high heat to melt the base pieces together. After cooling, the two components are fused.
