Frequently asked questions.

We work with a wide range of custom CNC materials, including stainless steel, carbon steel, alloy steel, brass, and aluminum. Each material offers unique strengths. Stainless steel provides excellent corrosion resistance. Carbon steel ensures high strength at competitive cost. Brass and aluminum are valued for precision and machinability.

Our machining team selects the best custom CNC materials based on your project requirements. This guarantees accuracy, durability, and efficient performance in industrial applications.

For more details about stainless steel properties, you can check the ISO Standards.

In CNC Machining Tolerances is the difference between the design size and the final part. It determines how accurate the part will be.

At Lebo Metal, we can achieve ±0.01 mm (±0.0004 in) for critical dimensions. This level depends on the material, part size, and geometry.

For general machining, we follow ISO 2768-m standards. This ensures reliable and consistent quality for both prototypes and batch production.

Hole tolerances can reach H7/H8, while shafts can be machined to h8/h9. With strict QC and advanced machines, we guarantee every part meets your tolerance needs.

Yes, we provide CNC surface finishing services. These processes improve part durability, resistance, and overall appearance.

We offer multiple finishing options: anodizing, zinc plating, nickel plating, passivation, phosphating, electrophoresis, powder coating, and polishing.

Materials like stainless steel, carbon steel, aluminum, and brass can all be finished. Each option ensures better performance or a decorative look.

Our finishing solutions help your CNC parts meet strict quality standards while matching your design needs.

Yes, we support small quantity CNC machining orders. Many customers need prototypes or trial runs before mass production.

Our minimum order quantity (MOQ) is flexible. This allows startups and R&D teams to test designs without high costs.

We provide the same precision and quality for small orders as for bulk production. Each part meets your design and tolerance requirements.

Fast lead times and flexible production ensure you receive reliable CNC parts, even for low-volume projects.

To prepare an accurate CNC machining quotation, we need the following details:

Part Drawings or 3D Models – CAD files (STEP, PDF, or DXF) with clear dimensions.

Material Requirements – Stainless steel, carbon steel, aluminum, brass, or other alloys.

Tolerance and Standards – ISO, DIN, or specific precision levels.

Surface Finishing – Polishing, anodizing, plating, or coating options.

Order Quantity – Prototype, small batch, or mass production.

Lead Time or Delivery Needs – Expected timeline or urgent requests.

Providing these details helps us calculate machining time, material cost, and ensure we meet your quality and delivery expectations.
