Frequently Asked Questions

What spindle speed range does the JET GHB-1340A provide?

The GHB-1340A offers 8 spindle speeds ranging from 70-2,000 RPM, giving machinists the flexibility to work with a wide variety of materials and part diameters at the appropriate cutting speed.

How many threading options are available on this lathe?

This lathe features 38 inch thread pitches ranging from 3-1/2-80 TPI, and 23 metric thread pitches ranging from .45-10 mm. The gear box gives wide inch threading and feed capabilities with gear changes, making it well-suited for both standard and metric threading work.

Can the tailstock be used to turn tapers on this machine?

Yes. The tailstock may be offset for turning taper, allowing the operator to produce tapered workpieces without the need for additional attachments.

What measures are taken to ensure the accuracy and longevity of this lathe?

The V-Way bed design is induction hardened and ground for a rigid machining surface. Hardened and ground gears are featured in the headstock and gearbox, compound and cross slide have backlash elimination for precise repeatability, and each machine ships with a tolerance test certificate confirming it meets precision standards. The headstock is also constantly oiled during operation, minimizing maintenance requirements.
