CK61140X3000 Heavy Load Horizontal Flat Bed CNC Lathe | Premium 3000mm Machining Lathe

The CK61140X3000 is a upgraded heavy-duty horizontal CNC lathe engineered for high-load, long-size metal turning tasks, specially designed for medium and large processing enterprises that need stable precision and strong cutting capability for 3-meter-long workpieces. Different from standard ordinary CNC lathes, this CK61140 series 3000mm model adopts thickened bed structure, reinforced transmission assembly and anti-deformation machining design, which can run continuously 24/7 for hard alloy, cast iron, carbon steel and stainless steel workpiece turning. It is a cost-effective large machining equipment replacing imported heavy lathes for global manufacturing workshops.

1. Unique Upgraded Design of CK61140X3000 Industrial CNC Lathe

1.1 Anti-deformation Integral Cast Bed Structure

This CK61140X3000 long CNC lathe adopts HT300 high-grade cast iron one-piece casting, finished with secondary natural aging treatment and vibration stress relief processing. The widened hardened guide rail reaches HRC52 hardness after intermediate frequency quenching, with wear-resistant plastic pasted on the sliding surface. It effectively reduces friction loss, avoids rail abrasion after long-term heavy cutting, and keeps overall machine geometry precision unchanged for more than 8 years. Compared with ordinary welded bed lathes, this model owns better shock resistance during deep cutting and intermittent cutting work.

1.2 Low-speed High-torque Spindle System

Tailored for large hard metal rough turning, the CK61140X3000 equips enhanced mechanical gear spindle with stable low-speed torque output, no spindle stall under full-load cutting status. Key spindle parameters for reference:

• Spindle through hole: Φ140mm, support continuous bar feeding processing

• Spindle speed: 2.2rpm - 280rpm, wide speed adjustment range

• Gear shift mode: automatic 4-grade mechanical gear shifting, bigger cutting torque than frequency conversion single drive

• Max workpiece bearing capacity: 6 tons between centers

1.3 Reinforced Hydraulic Tailstock & Feeding System

Equipped with upgraded heavy hydraulic tailstock with MT8 taper sleeve, 125mm effective sleeve travel, which can firmly support ultra-long shaft workpieces to eliminate bending deflection during high-speed turning. X-axis and Z-axis adopt high-precision C5 grade ball screw paired with original servo motors, achieving smooth feeding and low noise operation. The whole feeding system reduces tool vibration, greatly improving workpiece surface finish for fine turning process.

1.4 Flexible Tool Configuration Options

Standard 4-position electric tool holder for regular turning jobs; optional 6-position / 8-position hydraulic turret for multi-angle composite machining. Fast tool switching shortens workpiece clamping time, improves batch production efficiency for cylindrical parts, grooving, threading and chamfering integrated processing.
