Hartford's PBM-115A Horizontal Boring & Milling Center has been successfully installed and commissioned in South Africa and is now fully operational, helping the customer improve machining efficiency, process stability, and long-term manufacturing competitiveness for large components.


Designed to address the challenges of machining large workpieces—including heavy cutting loads, dimensional accuracy, extended machining cycles, and high structural rigidity requirements—the PBM-115A combines a rigid machine structure, high spindle torque, and stable machining performance to deliver reliable results for demanding manufacturing applications.

A Horizontal Boring & Milling Center Built for Large Workpieces

Large mechanical components are typically characterized by their size, weight, multiple machining surfaces, and substantial material removal requirements. These applications demand exceptional machine rigidity, spindle performance, and positioning accuracy.


The PBM-115A is specifically engineered for machining large mechanical components, structural parts, energy equipment, mold bases, and heavy industrial workpieces. Its robust construction enables long-term stable operation while maintaining excellent performance under heavy cutting conditions.


Insufficient machine rigidity can lead to vibration, dimensional inaccuracies, inconsistent surface finishes, and shortened tool life. Featuring a highly rigid machine structure and stable feed system, the PBM-115A minimizes cutting vibration, improves surface quality, and enhances dimensional consistency, providing an ideal balance between heavy-duty roughing and precision finishing.

Four-Speed Gearbox Delivers Powerful High-Torque Cutting Performance

The PBM-115A is equipped with a four-speed gearbox that automatically provides the optimal combination of spindle speed and torque for different machining conditions.


Compared with a single-speed transmission, the four-speed gearbox maintains stable power delivery during low-speed heavy cutting, high-load roughing, and precision finishing operations.


With a maximum spindle torque of 2,005 N·m (26 kW), the PBM-115A is well suited for machining large workpieces requiring high cutting forces. Whether performing deep cuts, high material removal, or machining tough materials, it delivers consistent cutting performance that helps reduce machining time and improve productivity.

Stable Performance from Heavy Cutting to Precision Finishing

Large-part machining requires not only high material removal rates but also excellent dimensional accuracy and surface quality. The PBM-115A supports the complete machining process—from roughing and semi-finishing to final precision finishing.


Its rigid mechanical structure and high-torque spindle minimize vibration and machining deviation throughout the cutting process, resulting in improved dimensional accuracy and superior surface finishes.


For manufacturers, consistent machining performance means more than producing high-quality parts. It also contributes to higher machine utilization, more predictable production schedules, lower manufacturing costs, and greater long-term competitiveness.

Supporting South Africa's Large-Part Manufacturing Industry

The successful commissioning of the PBM-115A in South Africa demonstrates Hartford's continued commitment to supporting manufacturers worldwide with reliable machining solutions for large workpieces.


South Africa's mining, energy, heavy industry, and large equipment manufacturing sectors require robust machining capabilities for oversized components. With its high rigidity, powerful spindle torque, and precision machining performance, the PBM-115A is well suited to meet the demanding requirements of these industries.


For Hartford, every successful machine installation represents more than equipment delivery—it reflects a long-term partnership with customers to improve manufacturing efficiency, strengthen production capabilities, and advance smart manufacturing.


Looking ahead, Hartford will continue delivering reliable, high-performance machine tool solutions that help manufacturers worldwide achieve greater productivity, precision, and manufacturing excellence.
