Application fit

Start with the workpiece and process. The model name is only a starting point.

Special-purpose machines

Dedicated boring, milling or combined stations designed around a defined part and cycle time.

Modular machining units

Integrate the spindle with a slide, column, fixture and CNC or special-purpose control.

Production cells

Concentrate compatible operations after tooling, load, guarding and service access are reviewed.

Retrofit projects

Compare center height, mounting, machine envelope and maintenance access with the existing machine.

XT60-2-BT50-MB selection questions

Confirm these items before the drawing and quotation are approved.

How should I choose the spindle interface?

Start from the holder, tool-change method, cutting load and required accuracy. Send the tool specification and operation for review.

Are all published speed values available on every build?

No. The approved limit depends on bearings, motor, drive ratio, tooling, cutting load and duty cycle.

What changes with the motor arrangement?

MF and MB layouts change the motor envelope, belt path, guarding and maintenance access. Compare the matching drawing with the real machine.

Can JNYO provide a dimensional drawing or 3D model?

Yes, compatible files can be requested after the exact spindle interface, motor layout, ATC and coolant requirements are identified.

What information is needed for a quotation?

Send the workpiece material, operation, tool details, target speed, cutting load, accuracy requirement, machine drawing, quantity and destination country.

Catalog source and configuration limits

JNYO product catalog, PDF page 25; JNYO product catalog, PDF page 26; Chinese edition, approximately 74 MB.

The catalog separates NT50 rear-drawbar configurations from BT50 automatic tool-change configurations. The 1,500 and 3,000 rpm spindle options have different bearing arrangements. XT60-1 and XT60-2 mounting dimensions must be checked against their respective annotations in the shared drawing.

Weights describe pictured configurations. Catalog roundness is not a workpiece-accuracy guarantee. Confirm the complete assembly, dimensional drawing, measurement conditions and supply scope before integration.
