Capabilities
- Trumpf L-3050
- Trump L-3030
- LiftMaster Sort
With two Trumpf Trumatic L3050 & L3030 Lasers we have the ability to make parts that are repeatable and accurate. Trumpf laser technology helps to ensure consistency from part to part with cleaner cutting. GK Machine has special fixturing and prefabricated parts to help us achieve fast turnaround and meet delivery times.
GK offers fast and efficient services with our two Trumpf Liftmasters. They can automatically load and unload sheets of metal to and from the laser cutting machines – for lights-out operations. This enables GK to achieve faster and more efficient production runs.
