Torchmate CNC Plasma Cutter
Description:
The tool consists of a CNC gantry with a 48"x96" table that carries a Hypertherm PowerMax85 plasma torch. Cuts are made vertically over a water tank. Four levels of torch power are available so that mild steel sheets ranging from 0.018" (26-Ga) to 1.25" thick may be cut. Maximum cut speed is 350 inches per minute.
This is a RED tool! Users must be trained and tool-tested before they are permitted to operate it.
Materials qualified for general use are: Mild Steel, Stainless Steel, and Aluminum. Other materials that have been successfully tested are: Titanium and Brass.
Driver software is called Torchmate 4 located on the attached computer and several installations around the Asylum. Input data is in the form of a 2-D sketch, either as G-Code (*.txt or *.fgc) or DXF (*.dxf). DXF files may be prepared on any convenient CAD syatem, including a resident program "Torchmate CAD" located on the drive computer. Alternatively, G-Code may be prepared separately as a text file and opened by "Torchmate 4" application.

Artisans Asylum Antwerp Building, 55 Antwerp Street, Allston. Adjacent to the Metals Shop in the northeast corner of the building.
