Precision CNC Machining for Semiconductor Equipment
Tik Precision manufactures custom semiconductor equipment components to customer drawings, including valve bodies, gas blocks, chamber components and precision fixtures. Our services combine CNC milling, turning and 5-axis machining with specified surface finishing and dimensional inspection.
Machining, Surface Finish and Inspection Requirements
Semiconductor equipment components often combine complex geometry, precision fits and specified surface requirements. We review machining methods, finishing requirements and inspection criteria together before production.
Early drawing review identifies machining access, critical dimensions, surface requirements and inspection methods. This helps align manufacturing with the part design and agreed acceptance criteria.
Complex Geometry & Machining Access
Plan machining access for cavities, intersecting passages, angled holes and multi-face features in valve bodies, gas blocks and chamber components.
Critical Dimensions & Fits
Control specified bore sizes, hole positions, flatness and mating dimensions to support component fit and alignment.
Material & Machining Review
Review the drawing-specified material grade, stock condition and machining behaviour before selecting tools, setups and the manufacturing sequence.
Surface Finish & Critical Areas
Identify specified roughness, polishing areas, surface treatment requirements and masking boundaries before machining and finishing.
Burr & Edge Control
Review cross-holes, internal passages, edges and sealing areas for burr removal while preserving drawing-defined geometry.
Inspection & Acceptance Planning
Agree critical dimensions, inspection methods and required records before production, with checks at appropriate manufacturing stages.
CNC Machining and Precision Finishing for Semiconductor Parts
Tik Precision supports semiconductor equipment components with CNC milling, turning, precision grinding and polishing. Machining routes, finishing requirements and inspection checkpoints are reviewed against customer drawings.
Drawing-Based Manufacturing for Semiconductor Equipment Parts
Valve bodies, gas blocks, flanges, housings and fixtures require different machining routes. We review geometry, material, tolerances and surface requirements to plan manufacturing and inspection for each part.

Material Review and Surface Finishing for Semiconductor Parts
Material grade, operating environment and surface requirements guide the machining and finishing route. Critical surfaces, polishing areas and acceptance criteria are reviewed before production.
Match the Material and Finish to the Drawing
Surface finishing can affect dimensions, fit and surface condition. We review polishing areas, treatment specifications, masking requirements and finishing allowances together with the part drawing.
- Confirm material grade and stock condition.
- Define polishing, treatment and masking areas.
- Account for finishing allowances on critical dimensions.
For semiconductor CNC machining quotes, please provide the material grade, tolerances, polishing or treatment requirements and inspection needs together with your drawing or 3D model.
Semiconductor Materials
Material selection depends on cleanliness, dimensional stability, insulation and equipment environment.
| Material | Typical Use | Review Focus |
|---|---|---|
| Aluminum Alloys | Semiconductor equipment frames, plates, chambers, brackets and precision housings. | Flatness, anodizing, visible surfaces and dimensional stability after machining. |
| Stainless Steel | Vacuum-related parts, equipment hardware, support components and durable interfaces. | Corrosion resistance, passivation, edge quality and surface cleanliness. |
| PEEK / Engineering Plastics | Insulating parts, spacers, precision plastic blocks and special functional components. | Deformation, clamping, burr control and dimensional changes after machining. |
| Copper / Brass | Thermal, electrical and conductive components used in equipment assemblies. | Conductivity, oxidation, tool marks and surface finish expectations. |
Surface Finishes
Finish requirements should be reviewed together with cleanliness and critical surfaces.
| Finish | Suitable For | Notes |
|---|---|---|
| Anodizing | Aluminum semiconductor equipment parts, panels, plates and housings. | Color, corrosion resistance, surface consistency and masking areas should be reviewed. |
| Passivation | Stainless steel components requiring cleaner and more corrosion-resistant surfaces. | Useful for selected stainless steel parts after machining and cleaning preparation. |
| Precision Deburring | Small holes, slots, sealing areas, sharp edges and precision assembly interfaces. | Burr control is important for cleanliness, assembly and inspection readiness. |
| Cleaning Preparation | Semiconductor equipment parts requiring controlled surface condition before delivery. | Cleaning expectations should be confirmed before quotation and production. |
Engineering Note
Material grade, surface treatment, polishing areas, burr control and inspection requirements should be confirmed before production. Any special cleaning or packaging requirements must be reviewed and agreed before quotation.
