What is CNC Drilling
CNC drilling is an automated machining process that uses computer numerically controlled equipment to create accurate holes, countersinks, counterbores and tapped holes on workpieces. It is often combined with CNC turning or milling to complete multi-operation parts in one setup.
Our CNC Drilling Capabilities
Our CNC Drilling Capabilities support high‑precision hole machining for diverse materials based on customer drawings.
Through-hole Drilling
Produce holes penetrating fully through the workpiece.
Blind-hole Drilling
Drill holes with specified depth without breaking through the part.
Countersinking
Machining tapered recesses for countersunk head screws.
Tapping
Produce internal threads inside pre-drilled holes.
Why Choose Our Machining Services?

Metal Drilling Parts
Custom metal drilled machining parts with precise hole‑making for mechanical assembly, available in multiple metal materials per customer drawings.
Aluminum alloy
Easy to drill with good chip removal, widely used for lightweight precision structural components.
Carbon & Alloy Steel
Excellent general machinability, ideal for conventional mechanical parts with moderate strength demands.
Stainless Steel (304/316/303)
Corrosion-resistant material; special cutting tools and coolant are required during drilling to avoid built-up edge.
Brass & Bronze
Highly machinable metal, delivering smooth hole surface finish for fittings and small precision components.
Cast Iron
Brittle material with good chip breaking performance, suitable for housings, bases and mechanical castings.
Titanium Alloy
High strength and lightweight; low drilling speed and dedicated tools are needed due to poor thermal conductivity.
Non-Metallic Drilling Parts
Custom non‑metallic drilled machined parts with precise hole‑making for mechanical assembly, available in multiple non‑metal materials per customer drawings.
ABS
ABS can be easily drilled and machined for general structural non-metallic components.
Nylon (PA)
Nylon allows stable drilling work and features good wear resistance for mechanical fittings.
Wood
Wood is available for drilling, commonly used for simple fixture plates and wooden tooling, with average dimensional stability and susceptible to moisture deformation.
POM (Delrin)
POM supports precise drilling and delivers low friction for gear and bushing parts.
PTFE (Teflon)
PTFE can be drilled to produce anti-adhesive fittings, sealing and insulating non-metal parts.
UHMWPE
UHMWPE allows drilling machining and has ultra-high impact and wear resistance for conveyor wear blocks and supports.

Frequently Asked Questions
Here you can find answers to frequently asked questions about custom CNC & EDM machining, material options, tolerances, quotation and delivery. Our team is ready to assist with any extra concerns.
Yes. CNC equipment can accurately process multiple holes, bolt patterns, cross holes, and closely positioned features. CNC programming and fixture control help maintain consistent hole location and repeatability across the entire component.
We can drill a wide range of materials, including aluminum, carbon steel, alloy steel, stainless steel, brass, copper, and engineering plastics. Cutting tools and drilling parameters are optimized according to material properties and hardness.
Hole accuracy depends on material, hole diameter, depth, machine capability, and required geometry. For tighter requirements, drilling can be combined with reaming, boring, or other secondary operations to achieve the specified dimensional and positional tolerances.
We can produce various hole diameters and depths, including precision blind and through holes. For deep or high-aspect-ratio holes, tool selection, chip evacuation, coolant delivery, and drilling strategy are carefully controlled to maintain accuracy and surface quality.
Yes. We support prototype, low-volume, and high-volume production. CNC programming and standardized process parameters help maintain repeatability while improving production efficiency for larger quantities.
Depending on the drawing requirements, drilled components can undergo reaming, tapping, countersinking, counterboring, deburring, chamfering, or surface finishing. These operations can be integrated into the manufacturing process to reduce secondary handling.
MOQ and lead time depend on part complexity, material availability, hole specifications, quantity, tooling, and inspection requirements. Prototype quantities and recurring production orders can both be accommodated.
Provide your 2D drawing or 3D model, material specification, hole diameter and depth, positional tolerances, quantity, and finishing requirements. Our engineering team can review the design and recommend an appropriate drilling process and production approach.
