Large-Bore CNC Pipe Threading Lathes

CNC Threading for Long Tubular Workpieces

Large-bore CNC pipe threading lathes are designed around the spindle capacity, support and rigidity required for long tubes, couplings and heavy threaded components. Typical applications include oil and gas pipe, drill collars, long tubular parts and large flanges.

This category currently includes the Handemo QK1322. Its model page provides the machine-specific information needed for detailed evaluation.

Define the Pipe and Thread Requirements

Provide the outside and inside diameter, length, weight, material, thread form, pitch, tolerance, end geometry, workholding and support method. These inputs are essential for assessing spindle capacity and planning a stable threading process.

Frequently Asked Questions

Why is spindle bore important?

It affects whether the tubular workpiece can pass through the spindle and how the part can be supported and clamped.

Can selection be based only on pipe diameter?

No. Length, weight, material, thread standard, chucking and support requirements are also critical.
