Material grade refers to the specific type of material used in CNC machining, such as aluminum, stainless steel, or engineering plastics. Each material has unique properties, such as tensile strength and corrosion resistance, which impact the performance and durability of the final product. Selecting the right material grade is vital to ensure that the components meet the operational requirements of the intended application.

2. Tolerance

Tolerance indicates the permissible variation in dimensions of a machined part. For example, tolerances can be as tight as ±0.005 mm or as loose as ±0.5 mm, depending on the application. In industries like aerospace or medical, tighter tolerances are critical for functionality and safety. Understanding tolerance specifications helps buyers assess the precision of the machining process and ensures that parts will fit and function as intended.

3. Lead Time

Lead time is the duration from when an order is placed to when the finished parts are delivered. In the fast-paced world of manufacturing, quick lead times (e.g., as short as 2-7 days) can significantly affect project timelines. Buyers must consider lead times when planning production schedules, as delays can result in increased costs and missed market opportunities.

4. Surface Finish

Surface finish describes the texture and quality of a part’s surface after machining. Common finishes include as-milled, anodized, or bead-blasted. The choice of surface finish can affect both aesthetics and functionality, such as corrosion resistance or friction levels. Buyers should specify surface finish requirements to achieve the desired performance and appearance of their products.

5. Production Volume

Production volume refers to the quantity of parts required. CNC services often have different pricing and lead time structures based on whether the order is for prototypes, low-volume runs, or mass production.
