Prototype and repeat production
Build the production route around quantity and feature relationships.
For prototypes, the priority is verifying fit, geometry and inspection access without overcommitting tooling. For repeat orders, bar stock, cycle sequence, tool-life monitoring, deburring and sampling become part of one controlled plan.
Share both the initial order and expected repeat demand. That context helps determine whether Swiss machining, conventional turning or another route is the practical choice.

Swiss machining or conventional turning?
Select the process from the complete part—not the name alone.
Swiss machining is especially useful for small slender geometry and complex bar parts. Conventional turning may be more efficient for larger diameters, shorter parts or simpler rotational profiles.
Ask for a Process ReviewPart geometry
Diameter, overall length, unsupported length and wall thickness influence the need for close guide-bushing support.
Feature density
Cross-holes, flats, slots, threads and back-end details may favor a multi-task Swiss route.
Order quantity
Setup and tooling effort must be balanced against prototype needs and expected recurring demand.
Inspection strategy
Small features and related diameters must be accessible to the selected gauges or measurement systems.
Swiss machining materials
Match the exact grade to machining and end use.
Material family alone is not enough. Grade, temper or condition, hardness, certification needs and required finish all influence tooling and quotation.
Stainless steel
Commonly selected for corrosion-resistant pins, shafts, fittings and instrument components. Specify the exact grade, condition and passivation requirement.
Carbon and alloy steel
Suitable grades can support mechanical pins, fasteners and wear components. Heat treatment, hardness and finish-machining sequence should be defined early.
Brass and copper alloys
Often evaluated for electrical contacts, connectors, fittings and components that need conductivity or favorable machinability.
Aluminum alloys
A practical option for lightweight small components. Grade, temper, anodizing and post-finish dimensions should be included in the RFQ.
Titanium alloys
Used for high-strength, corrosion-resistant applications where tooling, heat control, surface integrity and inspection require project-specific review.
Engineering plastics
POM, PEEK, PTFE and specified plastics can be considered when material stability, burr control, clamping and cleanliness are addressed.

Design guidance for Swiss parts
Give small features room to be machined and inspected.
A clear datum system and practical geometry reduce manufacturing assumptions before tooling and programming begin.
Length-to-diameter ratio
Identify straightness, runout and functional support requirements on long narrow parts so stock support and cutting loads can be planned.
Threads and thread relief
State the thread standard, size, pitch, class, handedness and gauge requirement. Provide practical relief where function allows.
Deep bores and small holes
Small tools need adequate access and chip evacuation. Define true depth, bottom form and the surface or flow requirement behind each bore.
Cross-holes, flats and slots
Dimension live-tool features from functional datums and identify their required orientation to the primary turned axis.
Burrs and edge condition
Call out edges that must remain sharp, receive a controlled break or be burr-free under magnification rather than relying on a broad note.
Critical fits and surface texture
Apply tight limits and roughness requirements where they protect motion, sealing, electrical contact or assembly—not automatically to every surface.
Swiss machining workflow
From drawing review to controlled delivery.
The process plan connects bar stock, machining sequence, in-process checks, finishing and final inspection to the current revision.
Drawing and quantity review
Confirm revision, material, annual or batch quantity, critical features, finish, inspection and packaging expectations.
Swiss process planning
Review bar size, guide support, tool access, main/sub-spindle sequence, live tooling, cut-off and back-working requirements.
Programming and first setup
Prepare tools, offsets, in-process checks and a stable operation sequence around the approved datum strategy.
Production and monitoring
Run the controlled bar-fed process while monitoring tool wear, burrs and characteristics that influence part-to-part consistency.
Inspection and finishing
Verify specified dimensions and functional features, coordinate approved finishing and package small parts to prevent mixing or damage.
Inspection for small precision parts
Measure the relationships that protect fit and function.
Small parts often combine miniature details, slender profiles and closely related front, side and back features. The drawing should identify which characteristics require special methods or records.
Explore inspection planningSmall diameters and micro-features
Optical inspection, microscopes, pins or appropriate gauges may be considered where conventional contact measurement is impractical.
Runout and concentric relationships
The inspection plan should reproduce the functional datum axis and identify which diameters, faces or threads must relate to it.
Thread verification
Define thread class and the agreed gauge or measurement method, including any allowance for plating or other post-machining finishes.
Burr and visual acceptance
Small cross-holes, slots and cut-off faces need explicit edge and cleanliness expectations, especially for fluid, medical-equipment or precision assemblies.
First article and sampling
State whether first-article results, dimensional reports, material records or recurring sampling are required before quotation.
Packaging and lot control
Miniature parts can tangle, scratch or mix easily. Quantity per package, separation, labeling and lot identification should be specified.

Swiss CNC machining FAQ
Answers for engineers and procurement teams.
For a feature-specific answer, upload the current model and controlled drawing with material, quantities and inspection requirements.
Request a drawing reviewWhat is Swiss CNC machining?+
Swiss CNC machining is a bar-fed turning process in which the stock is supported close to the cutting tool by a guide bushing. It is commonly considered for small, slender or feature-dense components that combine turning with drilling or milling.
How is Swiss machining different from conventional CNC turning?+
Conventional turning normally holds the workpiece farther from the cut, while Swiss-type equipment supports sliding bar stock near the cutting zone. That support can help with long small-diameter geometry. The most suitable process still depends on the complete part and quantity.
Which parts are good candidates for Swiss machining?+
Typical candidates include precision pins, miniature shafts, sleeves, bushings, screws, electrical contacts, nozzles, fittings and other bar components with several closely related features.
Can Swiss machined parts include milled features?+
Yes. Flats, slots, cross-holes and off-axis features can often be evaluated with live tooling. Tool access, feature orientation, cycle complexity and inspection requirements must be reviewed from the model and drawing.
Which materials can be reviewed?+
Projects can be reviewed in specified stainless steels, carbon and alloy steels, aluminum, brass, copper alloys, titanium and engineering plastics. Always provide the exact grade and condition rather than only a material family.
Can you support both prototypes and repeat orders?+
Prototype and recurring quantities can be reviewed. Share the first order quantity and expected repeat demand so material, tooling, inspection and production planning can be evaluated together.
What tolerances are possible with Swiss machining?+
Achievable tolerance depends on diameter, length, material, wall thickness, feature relationships, finishing and the measurement method. Mark only the function-critical limits on the controlled drawing for a project-specific capability review.
How are burrs controlled on miniature parts?+
Burr control starts with tool selection and operation sequence, then may include targeted deburring or finishing. Identify cross-holes, slots, threads and edges with special acceptance requirements in the RFQ.
What files are needed for a Swiss machining quote?+
Send a STEP or STP model and controlled PDF drawing when available, plus material grade, quantities, finish, critical dimensions, thread details, inspection records, packaging and delivery requirements.
What affects the cost of Swiss machined parts?+
Material and bar size, part length, feature count, special tooling, deep holes, threads, live-tool operations, deburring, tolerance, inspection, finishing and order quantity all affect quotation.
