Applications & Industries

Used KEN SABER 2840 is designed for large-component machining applications that require multi-axis tool positioning, a substantial worktable capacity, and high spindle torque. Its double-column construction and HEIDENHAIN 5-axis control make it a potential solution for complex milling operations across several industrial sectors.

Aerospace Component Machining

Suitable for machining selected aerospace structural components, aircraft frames, support structures, and complex housings. Its 5-axis configuration allows access to multiple machining angles, helping reduce repositioning during complex operations.

Automotive Mold & Die Manufacturing

Designed for large automotive stamping dies, injection molds, body panel tooling, and complex mold surfaces. Multi-axis tool positioning provides greater flexibility when machining contours, cavities, and angled features.

Heavy Machinery Manufacturing

The 4,000 × 2,000 mm worktable and 8,000 kg rated load capacity make the machine suitable for large machinery components, equipment housings, structural parts, and industrial tooling within its working envelope.

Energy Equipment Manufacturing

Applicable to selected power generation components, turbine-related housings, and other large industrial parts requiring multi-angle milling, drilling, and finishing operations.

Large Precision Engineering

The HEIDENHAIN TNC 640 controller, BT50 tooling system, and 5-axis milling head support complex machining operations for manufacturers producing large, intricate metal components.

A Cost-Conscious Choice for Expanding Machining Capacity

For manufacturers looking to add large-format 5-axis capability without purchasing a comparable new machine, the used KEN SABER 2840 is worth considering. Its suitability for a particular project should be evaluated against workpiece dimensions, materials, tooling requirements, and verified machine condition.

FAQ

Can the used KEN SABER 2840 perform simultaneous 5-axis machining?

Yes. According to the supplied specifications, the KEN SABER 2840 is equipped with a HEIDENHAIN TNC 640 CNC controller supporting simultaneous X, Y, Z, B, and C-axis control. The actual operating condition of the 5-axis system should be confirmed during machine inspection.

What is the maximum worktable capacity of the KEN SABER 2840?

The machine has a 4,000 × 2,000 mm worktable rated for 8,000 kg. This provides capacity for large molds and heavy industrial components, including their fixtures. The maximum machinable workpiece size depends on spindle orientation, tool length, fixturing, and machine clearances.

What spindle and tooling system does this used CNC machine have?

The KEN SABER 2840 uses a BT50 spindle with a maximum rated power of 37 kW, maximum torque of 1,200 Nm, and maximum speed of 4,000 rpm. It also has a 40-position automatic tool changer. The number of toolholders or cutting tools included in the sale should be confirmed separately.
