FAQ's

1. What’s the difference between CNC milling and CNC turning?

CNC turning is primarily used to create conical or cylindrical surfaces.

It involves the use of a lathe, which is a machine tool that rotates the workpiece around an axis of

rotation.

Various operations like cutting, drilling, turning, and threading are performed using a single-point

turning tool (SPTT) that maintains direct contact with the workpiece throughout the process.

In contrast, CNC milling is employed to produce flat surfaces using a milling machine. This process

utilizes a multi-point cutting tool or milling cutter. Unlike turning, milling relies on intermittent cutting

and involves multiple machine steps.

2. A quick guide to CNC machining parameters

Many of the crucial machining parameters are established by the machine operator during the

generation of G-code.

Among the primary parameters we will discuss are the CNC machine's build size and its precision.

CNC machines are equipped with a relatively spacious build area, particularly when compared to

3D printers.

CNC milling systems are capable of machining parts with dimensions of up to 2,000 x 800 x 100 mm

(78” x 32” x 40”), while CNC turning systems excel at machining parts with diameters reaching up to

Ø 500 mm (Ø 20’’).

CNC machining empowers the creation of components with exceptional accuracy and stringent

tolerances.

These machines are capable of achieving tolerances even finer than half the diameter of an average

human hair, with a precision of ± 0.025 mm or .001’’.

In cases where tolerances are not explicitly specified in the technical drawings, operators typically

machine the part with an accuracy of 0.125 mm (.005’’).

3. Post-processing and surface finishes for CNC machining

CNC-machined parts as they emerge from the machine often exhibit visible tool marks, a feature

that may not align with your specific part requirements.

Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the surface

appearance and elevating attributes such as wear resistance, corrosion resistance, and chemical

resistance.

Methods like anodizing, bead blasting, and powder coating present viable options for refining the

final presentation of your custom parts, allowing you to achieve the desired surface quality and

performance characteristics.
