Precision CNC Machining – Surface Finishing & Secondary Operations
Precision and Quality Highlights
| Precision & Quality | Details |
| Deburring & Edge Breaking | Every part passes through manual and mechanical deburring stations to remove sharp edges and machining burrs. We pay special attention to cross-holes, threads, and internal intersections. |
| Surface Finishing Options | We offer a range of post-machining treatments including bead blasting, brushed finishing, and passivation. Each process is selected based on your functional and aesthetic requirements. |
| Precision Cleaning | Parts intended for sensitive applications such as hydraulics and medical devices undergo multi-stage cleaning to remove cutting fluids, chips, and residues. Cleanliness levels are verified upon request. |
Product Range
Threaded Rods & Studs
Fully threaded rods, double-end studs, and custom fasteners machined from bar stock. We cut threads to class 2A or 3A tolerances, with options for chamfered ends and thread runout control.
Locating Pins & Dowels
Precision ground pins for fixturing, alignment, and assembly applications. Available with chamfered ends, tapped holes, or threaded bodies, in materials from tool steel to stainless.
Spacers & Standoffs
Custom-length spacers, standoffs, and bushings for panel stacking and mechanical separation. We hold tight length tolerances and provide clean, burr-free ends.
Machining Capabilities
| Machining Type | Details |
| Thread Rolling & Cutting | We cut or roll threads from 0.5 mm to 50 mm diameter, to class 2A, 3A, or custom specifications. |
| Broaching & Keyway Cutting | Internal and external broaching for keyways, splines, and special shapes |
| Knurling & Grooving | Straight and diamond knurling, plus precision grooving for retaining rings and seals. |
Production Process
Finish-Ready Design Review
Our team studies your design drawings, checking dimensions, tolerances, and materials. We identify features that may require secondary operations or special finishing.
Treatment-Compatible Material Selection
We pick the best material based on your needs, considering strength, cost, and machinability — with attention to how the material responds to surface treatments like plating or anodizing.
Post-Processing Aware Programming
Using CAD/CAM, we create detailed machining programs, optimizing tool paths and speeds. Features requiring post-machining finishing are clearly identified and programmed with appropriate allowances.
Surface-Conscious Machine Setup
Technicians carefully set up the CNC machine, ensuring proper workpiece fixture and tool alignment. Surface finish requirements are considered during tool selection and setup.
Finish-Ready Machining
Our state-of-the-art CNC machines work with high precision, making parts from raw materials. Parts are machined with appropriate stock allowance for post-processing if needed.
Pre-Finish Quality Verification
We check parts at every stage, using multiple inspection tools. Surface finish is verified before sending for secondary operations. Deviations are fixed right away.
Integrated Finishing & Protection
We coordinate all required finishing — polishing, plating, anodizing, passivation, heat treatment. After finishing, parts are cleaned, inspected again, and packaged carefully for safe delivery.
Customization Services
| Customization | Details |
| Custom Finishing | Choose from clear anodize, hardcoat, black oxide, zinc/nickel plate, passivation, or powder coating. |
| Heat Treatment | We coordinate annealing, stress relieving, hardening, and tempering to meet your mechanical property requirements. |
| Kit Assembly | We source fasteners, seals, or hardware and deliver complete assembled kits. |
| Custom Packaging | Individual bagging, foam layering, anti-static protection — we package to your handling requirements. |
