USED SUNFIRM MAXTEC MAXTEC

The Sunfirm Maxtec series lathe is engineered for large-diameter and long-length turning applications, especially in oilfield, heavy equipment and large component manufacturing. For example, the CST-42160 version offers a 42″ swing over bed, a 55″ swing over gap, and a machining length of 160″. Its massive structure, wide bed and strong spindle make it ideal for heavy cuts, long shafts, and large diameter workpieces.
The machine is typically equipped with a spindle bore of 7″ , a swing over bed of 42″, and X/Z travel that support high rapid traverse rates. The spindle nose is A2-20 in the example listing.  With CNC control, an 8-station turret and optional hydraulic tailstock, the machine offers a combination of size, automation, and rigidity.
