Used machine tool equipment

lathe CNC machine tool Iron bed

Used machine tool equipment refers to industrial processing machinery that has already been put into actual production in the machining industry and, after professional disassembly, inspection, repair, component replacement, precision adjustment, or complete refurbishment, can still stably perform metal cutting, forming, grinding, drilling, boring and milling, turning, and other machining operations. Such equipment is widely used in sectors such as automotive parts manufacturing, mold making, hardware processing, aerospace, and general machinery. Common types include CNC lathes, machining centers, grinders, milling machines, drilling machines, punching presses, and shearing machines.

Product Details

I. Technical Principles

The machine tool is powered by an electric motor or a servo motor, and operates through the coordinated work of the spindle drive, feed system, hydraulic system, and CNC control system:

The spindle drives the cutting tool or workpiece to rotate at high speed, achieving the primary cutting motion.
The feed mechanism uses ball screws and linear guides to drive the worktable or tool holder for precise displacement.
The CNC machine tool relies on CNC programming to control the coordinate trajectory, automatically completing the machining of complex shapes.
The entire machine ensures stable cutting processes and dimensional accuracy through rigid bed support, guide rail guidance, and lubrication systems that reduce wear.

II. Performance Data and Status Indicators

1. Machining Accuracy

After calibration, the positioning accuracy of ordinary machine tools can be controlled within 0.01–0.05 mm, while the repeat positioning accuracy of CNC machine tools can reach 0.005–0.01 mm, meeting the requirements for precision part machining.

2. Spindle Performance

The spindle speed, output torque, and runout are restored to factory standards. The speed range covers several hundred to over ten thousand revolutions per minute, with smooth operation and no obvious vibration.

3. Operating Efficiency

Key parameters such as rapid traverse speed, cutting feed rate, and tool change time reach 85%–95% of the new machine’s rated values, enabling continuous, stable batch production.

4. Structure and Electrical Systems

The bed, guideways, and worktable show no severe wear, deformation, or cracks; the servo system, frequency converter, control system, limit switches, and other electrical components function normally without fault alarms.

5. Scope of Application

It can perform various processes such as turning, milling, drilling, boring, grinding, and tapping. The processing diameter, stroke, load capacity, and other specifications comply with the original manufacturer’s design standards, allowing direct integration into the production line for machining operations, significantly reducing enterprise equipment procurement costs and commissioning time.
