Engineering components for special-purpose machines

XT30-2 XT30-2 Series

XT30-2 Boring & Milling Spindle Unit with Motor (Rear-Mounted)

XT30-2 spindle unit with a rear-mounted motor arrangement for compact CNC special machines, modular machining stations and retrofit projects.

  • Motor arrangementRear-mounted
  • Spindle interfacesNT30 / MT3 / ER32
  • Maximum listed speedUp to 8,000 rpm
  • Motor range0.55–1.5 kW (catalog range)

Confirm the rear clearance, drive path, 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.

XT30-2 motor-mounted configuration

Rear-mounted motor layout for a clear front-side envelope.

XT30-2-MB combines the XT30-2 spindle platform with a rear-mounted motor arrangement. Confirm rear clearance, drive routing, guarding, service access, tool interface and connection dimensions before selection.

Where XT30-2-MB fits

The rear-mounted layout should follow the complete machine structure.

01

Dedicated stations

Compact boring or milling stations that benefit from keeping the front side clear.

02

Modular CNC units

Slide-table assemblies with sufficient rear clearance for the motor and drive.

03

Automation cells

Integrated modules after rear guarding, cable routing and access are checked.

04

Retrofit projects

Replacement work where the rear envelope and mounting interface can be verified.

Published selection data

Model XT30-2-MB
Motor arrangement Rear-mounted
Housing / spindle Confirm housing and spindle material grades, treatment and inspection requirements on the configuration drawing; the cited XT30-2 catalog table does not specify material grades.
Spindle interfaces NT30, MT3 or ER32
Maximum listed speed Up to 8,000 rpm; configuration dependent
Catalog motor range 0.55–1.5 kW, with three-phase asynchronous or servo spindle motor configurations. Confirm the motor rating, electrical specification and drive ratio.
Bearing arrangement 7007AC/DB is listed for both bearing positions in the catalog. Confirm bearing 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 03–04 (PDF page 5) for the XT30-2 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 XT30-2 platform but place the motor differently.

Five inputs that prevent a wrong configuration

Operation

Boring, milling, drilling or combined process.

Workpiece

Material, feature size and production cycle.

Performance

Speed, load, finish and accuracy.

Rear envelope

Clearance, guarding and drive path.

Interface

Mounting drawing, orientation and control.

XT30-2-MB questions

Confirm these items before quotation.

How does XT30-2-MB differ from XT30-2-MF?

MB places the motor at the rear; MF places it at the front. Compare both drawings against the machine envelope, drive 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.

Is the motor included?

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

Can every configuration operate at 8,000 rpm?

No. The published maximum depends on the spindle, bearings, drive ratio, motor, load and duty cycle.

What should be included in the drawing request?

Provide the interface, rear clearance, spindle center height, mounting direction, guarding, drive routing and service access.

Send the rear envelope before choosing XT30-2-MB.

JNYO will compare the application, interface and motor space before confirming the configuration.
