CNC aggregate for maximum flexibility in machining centers
More performance for your existing CNC machine without expensive new investments: A CNC aggregate, also known as an adapter aggregate, expands your machining options immediately and precisely. Whether complex angle drilling or undercuts – as a specialist supplier, HS Drive TeC provides you with the technology that transforms your main spindle into a multifunctional machining centre. This reduces set-up times and downtime while significantly increasing productivity and cost-efficiency.
What is an adapter aggregate?
An adapter aggregate is an additional machining unit connected to a CNC machining centre to specifically extend the function of the main spindle. It performs operations that would be difficult or impossible to realize with the standard configuration. These include, for example, angle machining, cross drilling or specialized milling operations.
Depending on the design, a CNC aggerate can be used as a milling unit, sawing unit, or as a specialized module for specific machining tasks. It features an independent mechanical structure with gears, bearings, and defined interfaces to the machine control system. This allows additional axes to be implemented without changing the basic structure of the machine. In technical terminology, these modules are often referred to as machining units, as they significantly determine the functional diversity of the basic machine.
HS Drive TeC offers a wide range of processing aggregates.
Typical designs and functions of a CNC aggregate:
- angle heads (90°): for drilling and milling operations on workpiece edges
- swiveling angle aggregates: manually adjustable or infinitely variable via the C-axis for complex mitre cuts
- multi-spindle units: simultaneous drilling of multiple holes (e.g., hole rows)
- floating aggregates: for compensating thickness tolerances in the material by mechanically scanning the surface
- sawing units: for precise cutting and grooving operations, often with large blade diameters for high cutting depths
- planing units: for producing high-quality surfaces and precise profiles directly on the CNC machine
- cutting units: for precise cutting of soft materials such as foam, seals or textiles using oscillating knives
- grinding units: for the perfect finish of edges and surfaces, equipped with probing systems for uniform contact pressure
How does an adapter aggregate work?
The functional principle of an adapter aggregate is based on the mechanical redirection and transformation of the drive forces generated by the CNC machine’s main spindle. Once the aggregate is switched via the interface, a driver engages with the spindle. Inside the housing, a high-precision gearbox transfers the spindle’s rotational energy to the tool holder of the aggregate.
Depending on the design, the gearbox fulfills different functions:
- angular transmission: With an angle head, the axis of rotation is usually redirected by 90° to enable machining along workpiece edges. Dual-spindle units even allow the use of two different tools within one aggregate.
- speed conversion: Different gear pairings can increase output speed for high-speed applications or reduce it for powerful milling operations.
- torque optimisation: An adapter aggregate can be designed to deliver particularly high torque at low speeds, significantly improving machining capabilities in hard materials. Especially when used as a drilling unit, this reduction ratio provides the necessary power for large hole diameters.
A crucial technical detail is the torque support. Since the aggregate must be firmly seated in the machine while the tool spindle rotates inside, every adapter aggregate requires a locking pin. This secures the housing to the machine’s spindle box and prevents the entire unit from rotating. This is the only way to guarantee the absolute precision required for high-quality industrial components.
Efficiency through technology: precision and reduced set-up times
A high-quality CNC aggregate acts as a technological power booster. Since modern units are exchanged via the automatic tool changer, manual conversion work is almost completely eliminated, which drastically reduces set-up times.
To maintain this efficiency in the long term, the aggregates must meet the highest standards. Excellent concentricity and low-vibration bearings are the basis for the required industrial precision. Robust designs and integrated protection mechanisms also ensure maximum work safety and durability in shift operation.
Preserve value with professional spindle service
CNC aggregates are among the most heavily stressed components of a machine. Wear occurs not only through load but also through dust exposure. Regular maintenance is therefore essential to ensure long-term performance and precision. HS Drive TeC offers customized service concepts, including inspections to prevent unexpected failures and costly production downtime.
If a defect should occur, our comprehensive repair services come into play. Our team analyses the damage using state-of-the-art measuring technology and restores your unit using original spare parts. Our goal is to fully restore its original precision.
