A core focus of our contract manufacturing services is precision center grinding for demanding high-accuracy components. We machine workpieces up to 3000 mm in length and 1000 kg in weight, enabling cost-effective processing of large and heavy industrial parts. By utilizing our in-house center grinding machines, we achieve highly precise center holes and optimal concentricity conditions for all subsequent machining operations.

Our CNC subcontract machining services are complemented by turning, milling, as well as internal and external grinding to provide complete machining solutions from a single source. Comprehensive quality inspections — including dimensional measurement, roundness testing, geometric inspection, and surface finish control — ensure repeatable precision, high process reliability, and consistently superior component quality.

If you require short-notice center grinding services, precision machining of complex components, or flexible outsourcing of manufacturing capacity, Henninger is your reliable partner for high-precision subcontract manufacturing, CNC machining services, and premium contract center grinding solutions.
