Marking your material can be useful to identify cut plates to ease up the production and assembling process. The Voortman V320 can be used for layout marking by plasma or layout marking by milling. The choice of which marking technology to use depends on several requirements, such as:
- Allowed (or disallowed) heat distortion
- Required marking speed
- Required number of characters and data size
- Depth of marking based on post processes
- Technology or marking costs
Marking by plasma
Marking by plasma creates a surface discoloration and vaporizes a small amount of material. The advantage of plasma marking is that it can be done with the same plasma unit that is used for plasma cutting. The plasma unit will automatically switch to Argon gas for optimum marking results. Marking by plasma will increase your consumable costs and is more expensive than marking by milling. The speed of marking by plasma depends on the depth of the mark but goes up to 7,5 m/min (24-1/2 ft/min).
Marking by milling
From all marking types milling creates the highest quality mark which is even visible after shot blasting, painting or galvanizing. A high air output motor in the marking tool runs at 20.000 rpm to rotate the carbide milling tip to mark with a depth of approximately 1 mm (3⁄64”). The depth can be manually adjusted with the VACAM control software. The carbide milling tip has four useable sides which minimizes the marking costs. Marking speeds are possible up to 6,5 m/min (21 ft/min).
