Frequently Asked Questions

What is the spindle bore diameter on this lathe, and why does it matter?

The spindle bore measures 3-1/8 in., which is notably large for a lathe in this class. A larger spindle bore allows longer or larger-diameter bar stock to pass completely through the spindle, enabling you to turn longer workpieces without interruption and significantly expanding the range of jobs this machine can handle.

How many spindle speeds are available, and what is the speed range?

This lathe offers 12 spindle speeds ranging from 25-1,800 RPM. The Universal Gearbox allows you to change thread and feed rates without manually swapping gears, making speed and feed transitions fast and straightforward.

Does this lathe support both inch and metric threading?

Yes. The GH-1860ZX supports 61 inch thread pitches ranging from 1-5/8-72 TPI and 24 metric thread pitches ranging from .05-20 mm. This dual-thread capability makes it well suited for a wide variety of threading tasks in both measurement systems.

What safety and productivity features are built into this machine?

The lathe includes a large easy to use foot brake for rapid spindle stopping, an Electronic Chuck Key Holder to prevent accidental chuck key ejection, centrally located controls with a jog button for convenient operation, and a five position automatic carriage stop that increases productivity and part-to-part repeatability. A full length splash guard and coolant return system are also included to maintain a cleaner and safer work environment.
