We provides CNC Swiss machining services for custom small-diameter, complex precision components. We manufacture parts to your drawings and specifications, including inspection and finishing as required, for both low- and high-volume orders.
We machine slender components with stepped diameters, shoulders, reduced sections, and thin walls. Swiss-type machining supports the material close to the cutting point, helping reduce deflection when producing long, narrow profiles that are difficult to machine with conventional turning.
We manufacture custom Swiss-machined components with multiple diameters, cross-drilled holes, eccentric features, milled flats, and internal or external threads. Parts with different features on the front, sides, and back can be manufactured to your drawings, including non-standard geometries and application-specific designs.
Standard Dimensional Tolerance
±0.01 mm
Critical Diameter Tolerance
±0.005 mm
Roundness, cylindricity, position, and runout per drawing requirements.
Ra 0.8–1.6 μm
First-off parts are inspected against your drawings before production continues. Critical dimensions are monitored during machining, and finished parts are checked against the agreed dimensional and geometric requirements. Inspection reports and material certificates can be provided upon request.

We manufacture Swiss-machined components from stainless steel, aluminum, brass, carbon steel, and engineering plastics. Material and bar stock selection affect machining performance, burr formation, and finished surface condition.
Deburring, cleaning, passivation, anodizing, plating, and other specified finishes are considered according to the material and drawing requirements. Particular attention is given to intersecting holes, internal threads, and functional mating surfaces.
We manufacture custom Swiss-machined components for mechanical assemblies, precision instruments, fluid-handling systems, and industrial equipment.
Positioning, guiding, rotating and mechanical connection components with specified diameters, shoulders, and contact surfaces.
Components requiring internal bores, threaded connections, mating fits, and functional sealing surfaces.
Additional parts include precision fittings and custom Swiss-turned components manufactured to customer drawings, including non-standard configurations and specific assembly requirements.
For prototype and production orders, we review drawings, material specifications, quantities, and finishing requirements to determine the machining process and necessary secondary operations.
Repeat production uses established machining programs, tooling arrangements, and inspection criteria. Tool wear and dimensional changes require monitoring during longer runs, especially for small features and critical mating surfaces.
Combining machining operations can reduce additional setups and handling. Actual unit cost depends on the component design and order requirements rather than part size alone.
Send your drawings, material specifications, and estimated order quantity for a manufacturing review and quotation.
FREQUENTLY ASKED QUESTIONS
Swiss machining supports the bar stock close to the cutting tool using a guide bushing, reducing material deflection during machining. This makes it particularly suitable for long, slender components and small-diameter parts with demanding features. Conventional CNC turning may be more economical for shorter, larger-diameter, or less complex components. The appropriate process depends on part geometry, tolerances, and production quantity.
Yes. We manufacture custom Swiss-machined components based on customer drawings and specifications rather than fixed catalog designs. For quotation, please provide a 2D drawing or 3D model, material requirements, estimated quantity, and any specified finishing or inspection requirements. We review the design to determine machining feasibility and identify any details that need clarification before production.
Not necessarily. Part diameter alone does not determine whether Swiss machining is the best option. Length-to-diameter ratio, feature complexity, bar stock requirements, tolerances, and order quantity also matter. A short, simple component may be more economical to produce using conventional CNC turning, while Swiss machining can be advantageous for slender parts or designs requiring several operations.
Yes. Depending on the machine configuration and part design, Swiss-type CNC machines can combine turning with cross-drilling, milling, threading, and back-end operations. This can reduce the need to transfer components between machines. Features that require special tooling or additional setups are evaluated during drawing review.
We support prototype and production orders, with the manufacturing approach evaluated according to part complexity and quantity. For small batches, programming, tooling, and machine setup can represent a larger share of the unit cost. If the project is expected to move into repeat production, providing both the initial and projected quantities helps us assess the manufacturing approach and prepare an appropriate quotation.
Repeat production is based on established machining programs, tooling arrangements, and agreed inspection requirements. First-off inspection is used to verify critical features before continued production, while tool wear and dimensional variation are monitored during machining. Inspection frequency and documentation requirements can be determined according to the drawing and order specifications.
Cost depends on material grade, bar diameter, part length, geometric complexity, machining cycle time, tooling, order quantity, and any secondary finishing or inspection requirements. A small component is not necessarily inexpensive if it requires several cutting operations or difficult-to-access features. We evaluate these factors together when reviewing drawings and preparing a quotation.
Please send your technical drawings or 3D files, material grade, required quantity, and any finishing or inspection specifications. For parts with critical fits, threads, or assembly interfaces, clearly identifying those requirements helps us review the design accurately. If you have multiple production quantities in mind, include them so we can evaluate the quotation accordingly.
