About this machine

This Heller X 800 - Y 800 - Z 710 MM CNC Machining Center is a used machining center — sometimes referred to as a machining centre or CNC mill — dating from 2000 and currently located in Belgium. Machining centers are multi-axis computer-controlled machine tools designed to perform milling, drilling, boring, and tapping operations on metal and other materials with high precision and repeatability, typically using automatic tool changing to carry out complex work in a single setup. Heller is a well-established German manufacturer of CNC machining centers and transfer lines, serving industries such as automotive, aerospace, and general mechanical engineering.

Listed under the type designation MCP-H 250, the machine is configured for four-axis simultaneous machining, giving it the ability to execute complex contoured and angled cuts in a single pass. Motion on all axes is delivered through high-precision ballscrews driven by AC servo drives, ensuring accurate and repeatable positioning throughout the working envelope.

The spindle measures 100 mm in diameter and accepts ISO 50 toolholders, a robust taper size suited to heavy-duty cutting. Spindle speed ranges from 45 to 6,000 rpm, and the principal motor is rated at 62 kVA. Spindle power is quoted at 43 kW at 40% duty cycle. High-pressure through-spindle cooling is fitted as standard, directing coolant directly to the cutting zone for improved chip evacuation and tool life, and a dedicated cooling system is included. An automatic toolstore accommodates 52 tools, allowing extended unattended operation with minimal manual intervention.

The machine features four pallets, each measuring 630 × 500 mm, enabling workpieces to be loaded and unloaded on one pallet while machining continues on another, significantly reducing non-productive time. The NC rotary table offers a division resolution of 36,000 × 0.001 degree, providing highly precise angular positioning for multi-face and indexed machining operations. Machine control is provided by a Siemens Sinumerik CNC system, a widely used and well-supported platform in production environments.
