Confirm the front-side installation envelope, guarding, service access, spindle interface and machine connection drawing before ordering.

Drawing-led configurationApplication reviewGlobal project support

Final specifications depend on the workpiece, tooling, cutting load, duty cycle, motor and machine interface.

XT30-1 motor-mounted configuration

Front-mounted motor layout for application-led machine integration.

XT30-1-MF combines the XT30-1 spindle platform with a front-mounted motor arrangement. Select it after checking front-side space, guarding, service access, tool interface, target speed and connection dimensions.

Where XT30-1-MF fits

The motor position must match the real machine envelope and service plan.

Special-purpose machines

Dedicated boring or milling stations that can accommodate the front-mounted motor envelope.

Modular CNC units

Slide-table and modular assemblies requiring an XT30-1-class spindle and defined motor position.

Automation cells

Integrated machining modules after the front guard, belt path and maintenance access are checked.

Retrofit projects

Replacement or upgrade work where the existing front-side envelope and interface can be verified.

Published selection data

Model	XT30-1-MF
Motor arrangement	Front-mounted
Housing material	Confirm the housing material and treatment on the configuration drawing; the cited XT30-1 catalog table does not specify a material grade.
Spindle material	Confirm spindle material, heat treatment and inspection requirements for the ordered configuration; the cited XT30-1 catalog table does not specify a material grade.
Spindle interfaces	NT30, MT3 or ER32
Catalog spindle speed	4,500 rpm; 8,000 rpm with NSK bearings as listed in the catalog. Confirm the permitted speed for the selected spindle, bearings, motor, drive ratio and operating conditions.
Catalog motor range	1.1–2.2 kW, with three-phase asynchronous or servo spindle motor configurations. Confirm the motor rating, electrical specification and drive ratio.
Bearing arrangement	Catalog designations: 7207AC/TBT and 7206AC/DB. Confirm bearing brand, quantity, arrangement and precision class on the configuration drawing.
Catalog roundness	≤0.004 mm. This catalog value is not a spindle-runout specification or a guarantee of finished workpiece accuracy; confirm the inspection method and acceptance conditions.
Drive options	Synchronous belt, multi-rib belt or V-belt pulley configurations
Engineering files	Request the matching dimensional and compatible 3D files before integration

The cited catalog provides preliminary selection references. Confirm dimensions, materials, bearing arrangement, speed limits, motor and acceptance conditions on the configuration drawing and quotation. Roundness and spindle runout must be specified and checked separately.

Catalog reference: See the JNYO product catalog, printed pages 07–08 (PDF page 7) for the XT30-1 spindle table and front-/rear-mounted motor layouts. Chinese edition, approximately 74 MB. Request the configuration drawing before ordering.

Compare the arrangement before ordering

MF and MB share the XT30-1 platform data but place the motor differently.

Current modelXT30-1-MFFront-mounted motor arrangement. Confirm front-side space, guarding and service access.

Five inputs that prevent a wrong configuration

Operation

Boring, milling, drilling or combined process.

Workpiece

Material, feature size and expected cycle.

Performance

Target speed, cutting load and required accuracy.

Front envelope

Available space, guarding and service access.

XT30-1-MF questions

These answers define what must be confirmed before quotation.

What is the difference between XT30-1-MF and XT30-1-MB?

MF denotes a front-mounted motor arrangement; MB denotes a rear-mounted arrangement. Compare both drawings against the machine envelope, belt path, guarding and maintenance access.

How should I choose the spindle interface?

Choose NT30, MT3 or ER32 from the tooling, cutting load, changeover method and accuracy requirement. Send the tool specification and operation for review.

Is the motor included?

This page represents a motor-mounted configuration, but the exact motor type, power, speed, voltage and supply scope must be confirmed in the quotation.

Can every configuration operate at 8,000 rpm?

No. The catalog lists 4,500 rpm and 8,000 rpm with NSK bearings. The complete configuration, including the drive ratio, motor, load and duty cycle, must be confirmed before operating at the selected speed.

What should be included in the drawing request?

Provide the machine interface, available front-side envelope, spindle center height, mounting orientation, guarding limits and maintenance access.
