What Is CNC Drilling & How CNC Drilling Works
Drilling is the cutting process in which the workpiece does not move, making the cutter move, aligning the cutter center with the hole center, and making the cutter rotate. CNC Drilling is primarily done on CNC machines including CNC milling machines and lathes. CNC drilling service produces round holes, typically for machine screws and bolts. Drilling can process CNC drilling parts with metals, hard plastics, wood and most other rigid materials. There are several types of drilling machines available for CNC, including these drill presses: Upright, Bench and Radial. When in use, the step-by-step process for CNC drilling includes:
- The operator uploads and accesses the computer-aided design (CAD) or computer-aided manufacturing (CAM) file.
- The operator installs the appropriate drill bit and secures the designated material on the table.
- The operator starts the drilling process through the control panel or interface.
- The spindle lowers, drilling the appropriate hole sizes and diameters.

Junying CNC Machining Surface Finishes
Our CNC machining services provide a wide selection of metal surface finishing services after machining to improve the parts appearance, surface smoothness, corrosion resistance and other performance of your CNC machined parts.
- Painting: refers to an altering surface finishing process, spraying paint, pigment, or color to a solid surface as a colored protective layer, and can be done on metal or non-metal CNC machined components of any shapes, usually applied on aluminum, stainless steel and steel alloy parts. The purpose is to improve aesthetic appearance and prevent corrosion or oxidation.
- Passivation: a common chemical surface treatment method for steel and stainless steel, to remove ferrous contaminants or use a light coat of protective material to create a shell for enhancing the corrosion resistance or reducing the chemical reactivity.
- Electroplating/Plating: a process of using an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode, to change the properties of the metal surface or build up thickness for undersized parts.
- Powder coating/Powder coat: a functional and decorative finish, which is applied as a free-flowing, dry powder, employs electrostatically and then cured under heat, to create a hard finish that is tougher than conventional paint. The main applications including household appliances, aluminum extrusions, drum hardware, automobile, motorcycle, and bicycle parts.
- Anodizing/Anodized:an electrolytic passivation process of forming a thin layer of aluminum oxide on the exterior of aluminum CNC machined parts to increase the thickness of the natural oxide layer and protect the metal, as the layer has higher corrosion and abrasion resistance than aluminum.
- Polishing: also known as buffing, a process of rubbing the surface of parts or utilizing a chemical action to produce a smooth and shiny surface, make the surface get significant specular reflection or reduce diffuse reflection in some materials.
- Black oxide: also known as blackening, gun bluing or hot blackening, a chemical process of forming a black conversion coating on stainless steel, copper and copper based alloys, zinc, powdered metals, silver solder, and ferrous materials, to improve corrosion resistance and minimize light reflection.
- Conversion coating :also known as chromate conversion, the coating are used for metals converted to a protective layer through the chemical or electrochemical processes, primarily used as a corrosion inhibitor, decorative finish, or to retain electrical conductivity.
- Bead blasting/Bead blast: the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface.
- Abrasive blasting/sandblasting: the process or operation of propelling a stream of abrasive material composed of high-velocity sand-sizes particles against the metal surface under high pressure with blast equipment like air pressure system, to remove surface contaminants, clean metals or increase a texture, then change the smoothness or roughness of surface.
CNCLATHING also provides grinding, linishing, industrial etching, and more custom metal finishing service for presenting the best effect of your part.
