CNC Lathe
A CNC lathe is a Computer Numerical Control lathe—an automated machine tool that rotates a workpiece while cutting tools shape it into precise cylindrical parts.
CNC auto lathe
A CNC auto lathe is a high-speed, automatic CNC lathe designed for mass-producing small, long, precision parts (like pins, shafts, screws, bolts, connectors).
CNC engraving and milling machine
It’s a multi-purpose CNC machine that combines two functions:
engraving + milling .
Simple definition , A CNC engraving and milling machine is a computer-controlled machine tool
4 axis machining center
A 4-axis machining center is a CNC machine that can move and cut a part in 4 directions at the same time.
Sawing machine
A sawing machine is a machine that uses a saw blade to cut materials into pieces by moving the blade up and down or back and forth.
image measuring instrument
It’s a precision optical measuring machine (also called a vision measuring machine / 2.5D image measuring instrument).
It uses a high-resolution camera + lens + light source to take a clear picture of a part.
The computer software then automatically measures size, distance, angle, radius, profile, etc
No touching the part → non-contact measurement.
Laser Engraver
A laser engraver is a machine that uses a high-power laser beam to etch, mark
Turning And Milling Composite Machine Tool
A Turning and Milling Composite Machine Tool (also called Mill‑Turn Center / CNC Turn‑Mill Machine) is an advanced CNC machine that fully integrates turning and milling functions in one platform, enabling complete or near‑complete machining of complex parts in one clamping.
