430 Engraving Milling Bare Machine
Product Description
TH430 bare machine is integrally formed by precision casting through HT250 cast iron resin sand cores, and is totally aged. The DX430 bare machine is difficult to deform because the gantry and the stanchion are integrally cast and the rigidity is large. The worktable of the bare machine is movable. The guideway and the screw rod are produced by Hiwin, wherein the screw rod adopts C3-grade grinding ball screw rod. All bearings are imported bearings in pair and are matched with national well-known automatic lubricating devices. The stainless steel protective shield is provided in Y axis. All precision items shall strictly comply with the national standard before leaving factory. The appearance of bare machine shall be painted with required colors. The bare machine does not contain any electrical apparatuses.
