CNC Precision Machining Capabilities and Swiss-Type Specialization

Direct answer

Senhold supports drawing-based CNC precision machining projects. Its documented Swiss-type specialization uses a dedicated Citizen fleet for small-diameter, slender and multi-feature turned components. The machining route, material, tolerances, inspection and lead time are confirmed from the drawing and project requirements.

CNC precision machining and Swiss-type specialization

From machine structure to project RFQ

Machine structure and work support: A sliding headstock feeds bar stock while a guide bushing can support it close to the cutting zone. The drawing and documented machine configuration determine whether that arrangement is suitable.; Main/sub-spindle and combined operations: Turning, milling, drilling, tapping and cut-off may be combined when features, tooling access and the actual machine configuration permit. A sub-spindle handoff is a planning option, not an assumed capability.; Channel synchronization and collision control: Parallel operations can introduce shared-axis, tool-clearance, transfer and wait-state conflicts. A synchronized plan needs program review, machine-specific validation and a controlled first run.; Process planning and time study: A useful time study separates cutting, positioning, transfer, waiting, inspection and external operations. It supports comparison of routes without publishing unverified cycle-time or savings claims.; First article and inspection: The first article links drawing revision, setup, tool condition, datum strategy and measured results. Inspection scope and records must be agreed for the project.; Controlled RFQ handoff: The review handoff includes drawings, material, quantity, critical characteristics, finishing, inspection documents and application context. It does not create an automatic quotation.

Suitable Swiss-machined parts

Small-diameter parts with a high length-to-diameter ratio; Turned parts combining grooves, threads, cross holes or milled flats; Parts requiring repeatable concentric features in one setup; Medium-to-high volume parts where process stability matters

Other machining routes

Large-diameter plate or disc components; Box-shaped housings dominated by large milling features; Heavy roughing parts with large stock removal; Projects without a controlled drawing, material grade or inspection basis

Drawing checklist

Latest 2D drawing and optional 3D model; Material grade, condition and traceability requirement; Prototype quantity, batch quantity and estimated annual demand; Key tolerances, surface finish and special characteristics; Surface treatment, cleaning, packaging and inspection documents

Choose your project need

All three paths use the same RFQ workflow. The team follows up after submission; no automatic quote or fixed response time is promised.

Drawing and DFM support：Use this path when geometry, datum strategy, tool access or process routing needs engineering input.
Prototype or production quotation：Use this path when drawings, quantity and commercial scope are ready for quotation.
Quality documents or active-project support：Use this path to request project-specific inspection records, document scope or support for an existing project.
