CNC Milling Services in China, CNC Precision Machining …

Product Details: IN3DTEC provides CNC Milling services using 3 axis, 4 axis, and 5 axis milling machines. This subtractive manufacturing process involves mounting a cutting tool on a rotating spindle to remove material from a block of raw substrate. The workpiece is rigidly mounted to a table that moves or rotates on different planes, allowing the tool to work at various angles. The process is controlled by G-code, which programs the CNC machine to mill out parts from the raw material. Metals such as steel, brass, aluminum, nickel, and titanium can be machined, as well as plastics like Derlin (POM), PC, and

ABS. Surface finishes include as-machined, anodizing, painting & color matching, blasting & polish, black oxide, and brushing[2].

Pros:
– High precision and accuracy down to +/-0.01mm with 3 and 5 axis CNC machines
– Ability to produce parts with complex geometries
– Various surface finish options such as anodizing, painting, blasting, and black…
– Fast production times, with parts delivered in as fast as 3 days
– Wide range of materials available, including multiple types of metals and plasti…
– ISO9001-2015 certified quality assurance

Cons:
– Higher labor costs due to frequent manual intervention
– Additional costs for programming, jigs & fixtures, and machine maintenance
– Limited design freedom compared to metal 3D printing
– Material waste due to the subtractive nature of the process
– More complex and expensive equipment for 5-axis machining
