Advanced CNC Drilling Services for Global Markets


CNC drilling service is mainly used for drilling, reaming, chamfering and other processing. CNC drilling services are currently mainly used in the automotive, mould, shipbuilding, aerospace, and construction machinery industries, especially for some hardware parts with multiple holes that need to be processed. Of course, the precision CNC drilling shops small batch CNC machining service is also suitable for startups and designer teams, speeding up the time to market.


Although CNC drilling technology has been carried out in the global market for more than ten years, with the continuous development of mechanical automation, the CNC drilling service market has not only not decreased, but has become more and more popular so what advantages do CNC drilling services have so attractive? 



Online CNC drilling Services-Low Cost On Demand Manufacturing, On-Time Delivery



1. The traditional drilling service can only process some relatively simple and flat parts. In contrast, the CNC drilling service can process highly complex parts, such as complex curved and three-dimensional space surface parts, which is suitable for CNC drilling machines. Strong performance and flexibility are inseparable.


2. CNC drilling has high machining accuracy and stable quality. It only needs to do the workpiece clamping and positioning work at one time, and the parts can be automatically processed in multiple processes, which helps enterprises to improve production efficiency and save a lot of labour costs... ​​


3. CNC drilling service has good impact, toughness, hardness, and wear resistance and can drill, tap, and mill parts for a long time, so it is also called a multi-functional CNC drilling service

Available Surface Finishes for Tuofa CNC Drilling


Looking for metal stamping suppliers? You can choose a wide selection of metal surface finishing services after machining at Tuofa CNC machining manufacturer 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 machining 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 include 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.

More Custom Metal Finishing Service for Presenting the Best Effect of Your Parts


  • 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 is 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 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 a surface.

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.


Tuofa is an ideal choice if you are seeking the best CNC machining shop or CNC machining manufacturer for the fabrication of small, medium, large-sized products in low volume or mass production. Our exceptionally trained and experienced employees fabricate components in accordant.

CNC Drilling Services For Precision Machine Parts – China CNC Drilling Parts Factory, Supplier


Establishing a centering mark or feature before drilling, such as by:


  • Casting, molding, or forging a mark into the workpiece
  • Center punching
  • Spot drilling (i.e., center drilling)
  • Spot facing, which is machining a certain area on a casting or forging to establish an accurately located face on an otherwise rough surface.
  • Constraining the position of the drill bit using a drill jig with drill bushings


The surface finish produced by drilling may range from 32 to 500 microinches. Finish cuts will generate surfaces near 32 microinches, and roughing will be near 500 microinches.
