Machine Architecture and Structural Components
CNC wood cutting machines feature a rigid gantry-style frame constructed from welded steel or aluminum extrusions. The base platform typically consists of a vacuum table or T-slot bed measuring 1.2m x 2.4m to 2.5m x 5m for industrial models. Heavy-duty linear guide rails with recirculating ball bearings support the moving gantry, which houses the spindle carriage system. The Z-axis assembly incorporates a counterbalance mechanism to maintain positional stability during vertical movements.
