CK61100E/125E/140E/160E Series Large CNC Lathe

Description

The CK61100E/125E/140E/160E series are large CNC lathes with semi-closed-loop control functionality. These machines can handle workpieces up to 6 tons and are ideal for machining a wide range of complex-shaped shafts, sleeves, and disc-like components. They can perform turning operations on inner and outer cylindrical surfaces, conical surfaces, arc surfaces, end faces, grooving, chamfering, and thread cutting, making them perfect for heavy-duty machining tasks.

Main Structural Features:

1. Bed Structure:

   • The machine bed is of an integral box-type structure made from high-standard cast iron (HT300), cast in a single step and processed with secondary aging treatment for enhanced stability.

   • The guideway width is 755mm, offering strong rigidity and vibration resistance.

2. Headstock:

   • The headstock is designed to withstand heavy cutting operations, making it ideal for both rough and finish machining.

   • The gears are high-frequency quenched and precision ground, ensuring high precision, smooth operation, and low noise.

   • The spindle has a large diameter and is supported by precision heavy-load bearings arranged in a three-point support structure, ensuring stable rotation, high rigidity, and accuracy. The spindle also supports step-less speed variation and constant linear speed cutting.

3. Feeding Mechanism:

   • The X-axis and Z-axis use precision ground ball screw assemblies, ensuring high machining accuracy, positioning accuracy, and accuracy retention.

   • The automatic lubrication system provides centralized intermittent lubrication for all moving parts, ensuring smooth and reliable operation.

   • The longitudinal feed (Z-axis) is driven by an AC servo motor through a high-precision planetary reducer for specifications from 1000mm to 6000mm. For models exceeding 6000mm, the feed mechanism uses a rack and pinion drive system.

   • The machine boasts high positioning accuracy and repeated positioning accuracy, ensuring excellent consistency during operation.
