4 Axis Horizontal Boring Mill
Both configurations use an ISO 50 spindle taper, 360° B-axis table rotation and a separate W-axis for boring spindle extension. The JMB110B provides a 5,000 kg worktable capacity, while the JMB130B increases the maximum table load to 10,000 kg.
Product Description
The JMB Series uses a horizontal spindle arrangement with the worktable moving along the X axis, the headstock moving vertically along the Y axis, and the table moving across the Z axis. The W axis provides additional boring spindle extension, while the B axis allows the table to rotate through 360° for machining different faces of a workpiece.
The JMB110B 4 axis Horizontal Boring Mill Machine has a 110 mm spindle, 1800 mm X-axis travel, 1600 mm Y-axis travel and 1400 mm Z-axis travel. Its W-axis travel is 600 mm, and the table accommodates workpieces up to 5,000 kg. The spindle runs from 10 to 2000 rpm, with a 15 kW main motor and maximum spindle torque of 1520 N·m.
The JMB130B increases the spindle diameter to 130 mm and the machining range to 2000 × 2000 × 1500 mm on the X/Y/Z axes. Its W-axis travel reaches 800 mm, while the worktable supports up to 10,000 kg. The spindle speed is 10–2000 rpm, with 15 kW motor power and 1420/1600 N·m maximum spindle torque.
For both configurations, the spindle taper is ISO 50 and the Y axis uses a linear guideway. Optional attachment milling heads and tool magazines can be added according to the machining setup.

Product Features
Two Spindle Specifications
The JMB110B 4 axis Horizontal Boring Mill features a 110 mm spindle, while the JMB130B utilizes a 130 mm spindle. Both configurations employ an ISO 50 spindle taper and offer a speed range of 10–2000 rpm.
Two Guarding Structures
JMB110B: Features an enclosed guarding system with protective panels and viewing windows surrounding the machining area; ideal for production environments requiring the separation of the machining zone from the operator zone.
JMB130B: Features an open work area without the fully enclosed guarding found on the other model; this provides more direct access to the machining zone, facilitating easier observation and workpiece clamping operations.
These guarding differences represent structural configuration variations; please confirm the final configuration before ordering if you have specific requirements regarding the guarding method.
Independent W-Axis
The JMB110B offers a 600 mm W-axis travel, while the JMB130B provides 800 mm. The W-axis corresponds directly to the extension and retraction of the boring bar, extending the spindle's axial machining range.
360° B-Axis Rotation
Both configurations are equipped with a 360° B-axis rotary table, allowing the workpiece angle to be adjusted according to the machining surface and reducing the need to reclamp the workpiece when changing machining directions.
Varying Table Load Capacities
The JMB110B has a maximum table load of 5,000 kg, whereas the JMB130B increases this capacity to 10,000 kg. The JMB130B offers a higher load capacity, making it suitable for heavy castings, box-type workpieces, or machinery bases.
Optional Accessories
Accessory milling heads and tool magazines are available as optional configurations. These can be selected based on specific machining processes rather than applying a standardized configuration to every machine.
Product Advantages
The primary difference between the JMB110B and JMB130B extends beyond just the spindle diameter.
For medium-to-large workpieces, the JMB110B offers X/Y/Z travels of 1800 × 1600 × 1400 mm and a table load capacity of 5 tons, making it suitable for machining housings, bases, and mechanical components with manageable dimensions and weights.
The JMB130B increases the X/Y/Z travels to 2000 × 2000 × 1500 mm and the W-axis travel to 800 mm, while boosting the table load capacity to 10 tons, making it better suited for larger and heavier workpieces.
Additionally, the JMB130B features X/Y/Z positioning accuracy of 0.012 mm and repeatability of 0.010 mm, whereas the JMB110B offers 0.02 mm and 0.015 mm, respectively. Customers can select the appropriate model based on workpiece dimensions, weight, and machining precision requirements.
