About High-Rigidity CNC Machine for Heavy-Duty Roll MachiningCK84100 CNC Roller Lathe

Overview

The CK84100 CNC Roll Lathe is a heavy-duty, high-precision machine tool designed for machining large, heavy rolls and cylindrical parts. Built with advanced European-inspired design principles, it combines mechanical, electrical, and hydraulic technologies to deliver exceptional rigidity, stability, and performance for both rough and finish machining operations.

It is widely used in the machinery manufacturing industry for processing planes, curved surfaces, holes, and rotary parts, including outer circles, end faces, grooves, and profiles on rolls and similar components.

Core Features

High-Rigidity Structure

Three-way modular design with a heavy-duty four-rail bed ensures exceptional rigidity, vibration resistance, and long-term precision retention, even under heavy cutting loads.

Advanced & Reliable Performance

Adopts proven European design and process technology, with a standardized, interchangeable component structure. The machine offers reliable performance, easy operation, and low maintenance requirements.

Multi-Process Machining

Supports three-axis linkage (longitudinal, cross, and radial motion) for a wide range of operations, including turning, milling, boring, drilling, rigid tapping, reaming, and countersinking.

Superior Machining Quality

Achieves high precision up to IT6IT7 and surface roughness down to Ra0.8 m, meeting the requirements for precision parts and high-quality roll finishing.
