Brass Plate for CNC Engraving

Name: Brass Plate for CNC Engraving
Brand: SGZ

Overview

What This Product Is

SGZ Brass Plate is cut specifically for CNC engraving rather than for general fabrication. It is supplied unpolished with around +0.13 mm on thickness, so the shop can grind or polish the blank flat on its own machine before the cutter touches it.

Grinding allowance built in

Around +0.13 mm thickness deviation, deliberately left for grinding and polishing.

Saves cutter life

The plate is specified for engraving, which helps knife life on long runs.

Wide gauge range

0.7 mm through to 50 mm.

Long blanks

Up to 2000 mm long and 400 mm wide.

Who it is for

Buyers Who Specify It

CNC engraving job shops

Shops that grind their own blanks and want the allowance left on.

Trophy, plaque and signage engravers

Work where the brass stays visible in the finished part.

Hot-stamping die makers

Brass dies for foil stamping on paper, leather and plastics.

Mould and electrode shops

Brass stock for engraved inserts and electrodes.

Problems it solves

What Goes Wrong Without It

Plate delivered at final thickness leaves nothing to correct a warped blank. SGZ leaves around +0.13 mm so you can grind it flat.
Brass that is not specified for engraving wears cutters faster. This grade is chosen for engraving performance and knife life.
Sourcing a single thickness limits what you can quote. This plate covers 0.7 mm to 50 mm.
Shops that do not know how to take the allowance off get a poor finish, so SGZ publishes a grinding and polishing video.

Comparison

How It Compares With the Alternatives

Polished Copper Plate for Photoengraving and Etching

Copper is mirror polished and bought for chemical etching in ferric chloride. Brass is unpolished and bought for mechanical engraving.

Polished Zinc Plate for Engraving and Etching

Zinc is softer and cheaper per sheet and is used where the plate is a tool. Brass is used where the engraved brass itself is the product.

Use Guide

Grind or polish the blank on your own machine first; the +0.13 mm is there for that.
Set your datum from the ground face, not from the as-delivered surface.
Engrave with your normal brass tooling and feeds.
