Floor Type Boring Mills

Floor Type Boring Mills are heavy-duty machine tools developed for machining oversized components that require long-axis movement, substantial workpiece capacity, and flexible boring access. Unlike conventional enclosed machining centers, the floor-type configuration provides an open working area that can accommodate large components and support machining requirements across extended distances.

The JFB series includes JFB130B, JFB160B, JFB130BZ, and JFB160BZ, with 130 mm and 160 mm spindle diameter options. The machines are designed for demanding industrial applications where large workpieces require boring, milling, drilling, and other machining operations within a stable production environment.

With a maximum X-axis travel of up to 20 meters, table load capacity of up to 30,000 kg, and a 360° B-axis, these Floor Type Boring Mills provide a flexible machining solution for manufacturers working with large-scale machinery and complex industrial components.

Large workpieces can present challenges in terms of positioning, accessibility, machining range, and stability. Floor Type Boring Mills address these requirements through an extended floor-type machining layout that allows large components to be positioned within a spacious working area.

The JFB series can accommodate table loads of up to 20,000 kg on the JFB130 models and up to 30,000 kg on the JFB160 models. This makes the equipment suitable for manufacturers processing heavy mechanical components that require substantial support during machining.

The extended machining range is also beneficial when working with long structural parts or components with multiple machining locations. Instead of repeatedly moving a large workpiece between machines, the extended travel allows more machining operations to be completed within the same setup.

Boring is commonly required when large components need accurate internal holes, bearing seats, mounting holes, or other precision-machined surfaces. The horizontal spindle arrangement allows the cutting tool to access large components effectively while maintaining a suitable machining orientation.

In addition to boring, the machine can support a variety of machining operations according to the selected configuration and tooling system, including:

This combination makes Floor Type Boring Mills suitable for production environments where several machining processes need to be performed on large industrial components.

The JFB130B and JFB130BZ models use a 130 mm spindle, while the JFB160B and JFB160BZ models are equipped with a 160 mm spindle.

The different model configurations allow manufacturers to select equipment according to the required spindle capacity, workpiece size, table dimensions, machining range, and production requirements.

The spindle system uses an ISO 50 taper and provides a speed range of 10–2,000 rpm. Depending on the model, spindle motor power ranges from 25/30 kW to 31/30 kW.

For applications involving demanding cutting conditions, the available spindle torque and axial thrust provide the machining capacity required for large industrial workpieces.

The 360° B-axis provides additional positioning flexibility when components require machining from different directions. Combined with the available axis movements, this configuration can help operators reach different machining areas without repeatedly changing the workpiece setup.

For production involving large housings, structural assemblies, or irregular industrial components, reducing setup changes can be particularly valuable. It can simplify the machining process while maintaining a consistent reference position throughout multiple operations.

The available milling head configurations include:

The machine can also be equipped with a 40-tool magazine, with 60-, 80-, and 100-tool options available for applications requiring a larger selection of cutting tools.

Floor Type Boring Mills are commonly suited to industries where large components and heavy machining operations are part of the manufacturing process.

Depending on the machine configuration and process requirements, Floor Type Boring Mills can be considered for:

The actual suitability of a machine should be confirmed according to the dimensions, weight, material, hole requirements, machining accuracy, and production process of the workpiece.

The JFB series can use SIEMENS 828D or FANUC 0i CNC control systems. This provides customers with a choice based on their existing machining environment and operator familiarity.

For manufacturers already operating CNC production lines, selecting a familiar control system can simplify machine integration and operator training.

The machine can also be configured with optional tooling and supporting equipment according to the intended machining process.

A suitable Floor Type Boring Mill should be selected based on the complete machining requirement rather than a single specification.

Important factors include:

For large or irregular workpieces, providing a 2D drawing, 3D model, workpiece dimensions, weight, material, and required machining operations can make the machine selection process more accurate.

Every large-part machining application can have different requirements. The JFB series supports configuration adjustments based on the actual production process.

Customers can discuss requirements for spindle configuration, milling head type, tool magazine capacity, rotary table, load-bearing table, CNC control system, and other auxiliary equipment.

The final machine configuration can therefore be evaluated around the customer's actual workpiece rather than relying solely on a standard machine specification.
