Send the operation, workpiece, tooling, target speed, load, duty cycle and machine interface drawing for configuration review.
Final specifications depend on the workpiece, tooling, cutting load, duty cycle, motor and machine interface.
XT40-1 BT40 servo facing head
A BT40 servo facing head for machining faces, steps, contours and bore features on fixed or non-rotating workpieces with CNC interpolation.

Application fit
Start with the workpiece and process. The model name is only a starting point; final selection follows the tooling, load and real machine layout.
Fixed-workpiece machining
Machine a fixed or non-rotating workpiece when a conventional rotating table or lathe arrangement is not the right fit.
Interpolated faces and contours
Use CNC interpolation for controlled facing, steps, tapers and other radial tool movements.
Internal and external features
Evaluate internal or external faces, threads, linear boring, chamfers and multi-step boring in one process plan.
Turning-function retrofit
A servo facing head can support selected lathe-like or U-axis-like operations after the machine control and structure are checked.

XT40-1-BT40-SMB selection questions
Confirm these items before the drawing and quotation are approved.
What is the difference between a servo facing head and a conventional boring head?
A servo facing head adds controlled radial tool movement through a facing-head slide, enabling selected faces, steps, contours and bore features on a fixed or non-rotating workpiece. The machine structure and CNC interpolation must support the operation.
Which FA-408 or FS-620 option should I choose?
Choose from the workpiece diameter, required radial stroke, tool load, speed, accuracy and available envelope. The published data shows 8 mm / 20 mm slider-stroke options; confirm the exact model in the drawing and quotation.
Are 1,600 rpm and 1,200 rpm available on the same build?
They are published speed options associated with the facing-head data. The final limit depends on the exact head, bearing arrangement, servo, tooling, load and duty cycle.
Can the facing head replace a lathe or U-axis?
It can support selected lathe-like or U-axis-like operations, but it is not a universal replacement. Confirm interpolation, rigidity, workholding, tool access, control logic and the required acceptance test.
What information is needed for a servo facing-head quotation?
Send the workpiece drawing, feature diameters, required stroke, tool details, target speed, cutting load, interpolation method, servo/control system, machine interface, quantity and destination country.
Catalog source and configuration limits
JNYO product catalog, PDF page 30; Chinese edition, approximately 74 MB.
The facing-head table is a separate specification from the ordinary boring spindle. Where speeds, strokes or bearings are separated by a slash, the source does not fully map each value to each variant; confirm the complete combination rather than assigning values by their order.
Facing-slide repeat positioning, spindle roundness and finished-workpiece accuracy are different measures. Confirm test conditions and acceptance methods independently.
Weights describe pictured assemblies. Confirm the complete configuration, matching drawings, controls and supply scope before integration. Catalog values are not workpiece-accuracy or delivery commitments.
Move from product review to machine integration.
Use the model as a starting point. The approved dimensional drawing and configuration record remain the final integration reference.
Confirm mounting faces, center height, spindle interface and machine envelope.
