Book

CNC milling machine: CNC STEP USA S720

This cutter can be used to create different shaped models out of softer materials (e.g. wood, plastic) and/or soft metals (e.g. aluminum). The models are created by removing material from the chunk of material we start off with. A piece of the material from which we want to create the final product is placed into the machine (of course, the piece needs to be larger than the final product). The machine uses a fast rotating tool, not dissimilar to a drill, to cut the desired shape.
This cutter can be used to produce anything from models of buildings, streets or settlements or even a 3D picture (profile) that can be created from a 2D picture or painting with the use of different software.
Models can measure up to 720 x 420 mm in and 110 mm in height.
The entry data is CNC code, which is generated from a 3D computer model.
