CKH(J) 61125/160/200 heavy-duty CNC lathe

Max capable of handling workpieces weighing up to 16,000 kg

Guideway width of 1100mm

Description

The CKH(J) 61125/160/200 series heavy-duty CNC lathe is a high-performance machine with a wide range of applications and notable advantages. Its semi-closed-loop control system and 16-ton load-bearing capacity make it ideal for machining complex parts in various shapes. Below are its main structural features:

  1. Bed Structure:

    • The bed is an integrated box-type structure made of high-grade cast iron (HT300), cast in one piece and subjected to secondary aging treatment, ensuring strength and stability.

    • The guideways have a width of 1100 mm, enhancing the machine’s load-bearing capacity and stability.

  2. Spindle Box:

    • The box-type structure provides high rigidity, suitable for heavy-duty cutting operations.

    • The spindle gears are subjected to high-frequency quenching and precision grinding, ensuring high accuracy, smooth operation, and low noise.

    • The large spindle diameter is supported by precision heavy-duty bearings in a three-point support configuration, providing stable rotation for both heavy cutting and precision turning.

    • The automatic forced circulation lubrication system ensures smooth operation of the transmission system and effective cooling.

    • The machine supports stepless speed regulation and constant linear speed cutting, accommodating various machining needs.

  1. Feed System:

    • The Z-axis sliding guideways are equipped with TSF soft strips, greatly reducing the friction coefficient and improving servo response performance.

    • The X-axis feed is driven by an AC servo motor connected to the ball screw through a flexible coupling, ensuring high machining accuracy, positioning precision, and accuracy retention.

    • The machine features an automatic lubrication system for all motion pairs, which ensures proper lubrication during operation.

    • For longitudinal (Z-axis) feed, the system uses an AC servo motor and high-precision planetary gearbox, ensuring stable and precise feed motion.

This heavy-duty CNC lathe is not only highly accurate in machining and repeat positioning but also performs efficiently and stably under heavy-load conditions, making it ideal for machining complex parts. It is widely used in industries such as aerospace, shipbuilding, metallurgy, and petrochemical industries.
