- Low-volume CNC machining
- Small and medium production batches
- Scalable production for larger quantities
- Engineering support before production
- Secondary finishing and surface treatment
02
Precision CNC Parts Without Unnecessary Process Complexity
Dimensional accuracy depends on more than simply putting a drawing into a CNC machine. Material selection, machining strategy, workholding, tool selection, tolerances, inspection, and finishing can all influence the final component.
Boraco supports high precision CNC machining parts with 3-axis, 4-axis and 5-axis machining capabilities. For complex geometries, 5 axis CNC machining parts can reduce multiple setups and provide better access to difficult features.
For applications requiring tight dimensional control, our engineering and quality teams review drawings and production requirements before machining. This helps identify potential manufacturing issues before they become expensive production problems.
For applicable components, Boraco can work toward machining tolerances down to approximately ±0.005 mm, depending on material, geometry, dimensions, tolerance requirements, and production conditions.
03

04
Production Capacity That Matches Your Order Size
A common problem with CNC sourcing is finding a supplier that is suitable for both today's order and tomorrow's production requirements.
Boraco operates a 2,000 m² manufacturing facility and has more than 50 CNC machines supporting different machining requirements. Production capability can range from individual prototypes and engineering samples to high-volume orders of 1 to 1,000,000+ parts, depending on component complexity and project requirements.
This gives procurement teams more flexibility when moving from CNC prototype machining to low volume CNC machining and eventually larger production programs.
Instead of selecting a supplier purely by the lowest prototype quotation, buyers can evaluate whether the manufacturer has the engineering, equipment, quality control, and production capacity required for the complete project lifecycle.
What Problems Does Our CNC Parts Machining Service Solve?
Most frequent questions and answers
Prototype machining and repeat production require different levels of process control. Boraco uses engineering review, production planning, dimensional inspection, and quality control procedures to help maintain consistency as order quantities increase.
Many CNC projects require more than milling or turning. A finished part may also require surface treatment, heat treatment, laser engraving, sheet metal components, die casting, or other secondary processes.
Boraco combines CNC machining with multiple supporting manufacturing and finishing capabilities, reducing supplier coordination for suitable projects.
Engineering changes are common during product development. Material substitutions, tolerance adjustments, geometry revisions, and production-volume changes can affect cost and manufacturability.
Boraco provides engineering support during quotation and production so buyers can discuss manufacturability before committing to a production run.
You can submit your 3D CAD files (STEP, IGES, or x_t) along with 2D drawings specifying tolerances via our secure portal. As a direct China CNC machining supplier, Boraco delivers detailed quotes and DFM feedback within 24 hours.
