HELLER H 4500 HORIZONTAL MACHINING CENTER

Technical Description

The HELLER H 4500 is a high-performance horizontal machining center offering precision and versatility for complex milling operations. It features equal X, Y, and Z-axis travels of 31.496 inches, enabling substantial workpiece handling within a 4-axis configuration controlled by a CNC Siemens system. Powered by a robust 51 hp motor, it operates at a maximum spindle speed of 10,000 RPM, suitable for a wide range of materials and machining tasks. The machine employs an HSK100A tool taper, a high-speed, high-precision hydraulic tool holder standard known for exceptional clamping stability and low runout, ideal for heavy-duty roughing and finishing applications. Its automatic tool changer accommodates up to 50 tools, enhancing productivity through minimal tool change times. The pallet system supports dimensions of 19.685 inches by 24.803 inches, allowing efficient part setup and repeatability. Overall machine dimensions measure 7300" x 3350" x 3650", reflecting its industrial-scale footprint. This combination of rigid construction, advanced CNC control, high-capacity tool management, and precision taper tooling makes the HELLER H 4500 a reliable solution for aerospace, automotive, and mold/die manufacturing sectors requiring high accuracy and throughput. The HSK100A taper ensures excellent vibration damping, repeatability below 0.0001” runout, and stability critical for high-precision machining.
