The SDVEDON CW61125 is a flagship extra-heavy-duty horizontal engine lathe, specially designed for high-efficiency heavy turning of extra-large-sized shaft parts, disc sleeve parts, flange parts, and wind power components. As a top-of-the-line model in the CW series, it combines ultra-high rigidity, ultra-large processing range, and stable precision, making it an indispensable core equipment for heavy machinery manufacturing, wind power equipment, aerospace, and large-scale forging processing enterprises.
Built with a high-strength cast iron bed and 755mm ultra-wide guideway, the CW61125 has undergone strict finite element optimization and double artificial aging treatment, which effectively eliminates internal stress, ensures the stability of the machine body, and provides excellent vibration resistance during heavy cutting. The bed can withstand a maximum center load of 6000kg, ensuring consistent machining accuracy even under long-term high-intensity operation of extra-large workpieces.
Equipped with a 22kW high-torque main motor, this lathe delivers a spindle speed range of 3.15-315rpm (21 forward kinds, 12 reverse kinds), easily handling heavy rough turning and high-precision finish turning of various materials such as carbon steel, alloy steel, and stainless steel. The 130mm large spindle diameter and 140(1:20) spindle taper ensure reliable clamping of extra-large workpieces, and the spindle structure is optimized for ultra-high torque output, meeting the processing needs of extra-large through-hole parts and bar stock.
