CNC Drilling Service
Our CNC drilling service doesn’t just punch holes — it creates precisely positioned openings with tolerances that would make a watchmaker jealous. We’re talking accuracy down to ±0.001 inches across materials that other shops avoid — from aircraft-grade Aluminium und rostfreier Stahl zu Titan and those tricky advanced composites. Our ISO 9001:2015 certification isn’t just a piece of paper on the wall — it’s your guarantee that every hole meets those exacting standards your project demands.
Where we really shine is handling the tough stuff — those deep holes extending up to 150 mm that would cause other shops to break out in a cold sweat. Using specialized techniques like gun drilling and BTA methodologies, we deliver results for industries where failure simply isn’t an option — aerospace components that absolutely cannot fail at 30,000 feet, medical devices that patients’ lives depend on, critical automotive systems, and electronics where microscopic precision makes the difference between success and failure. When a misplaced hole by even a few thousandths of an inch would mean disaster, that’s precisely when our multi-axis capabilities prove their worth.

How We Achieve Precision
Think of CNC drilling as a robot with superhuman patience and precision. The whole system works by combining automated positioning with real-time monitoring that catches issues human operators might miss. Our machines follow G-code instructions – basically digital recipes that control everything from how fast the drill bit spins to when coolant gets sprayed and how quickly the drill moves into the material. Behind the scenes, sophisticated CAD software plots out the perfect path for each hole, shaving seconds off cycle times while still hitting those crazy-tight specs your project demands.
Smart Factory Features
- Tiny IoT sensors constantly monitor vibration, temperature, and cutting forces – catching problems before they ruin parts
- Smart algorithms actually predict when tools are about to fail, eliminating those costly mid-job breakages
- Digital twin technology lets us run simulations before cutting actual material, working out bugs virtually
- Our cloud-based dashboards track everything happening on the shop floor across multiple machines
The system automatically picks the perfect tool for each job from libraries containing everything from standard twist drills to specialized micro drills smaller than a human hair. For those challenging deep holes, our high-pressure coolant systems blast cutting fluid at up to 3000 PSI – that’s stronger than many pressure washers – keeping chips flowing out and temperatures under control even during the toughest operations.

Why Choose Our Deep Hole Drilling Expertise?
Deep hole drilling at Yijin Hardware employs gun drilling and BTA drilling methodologies for depth-to-diameter ratios exceeding 10:1. Gun drilling utilizes single-lip cutting tools with internal coolant channels to maintain straightness tolerances within ±0.002 inches over extended depths. BTA systems provide faster material removal using larger diameter tools with external chip evacuation for small and large production runs.
Technische Daten
- Gun drilling capabilities: 2 mm to 50 mm diameter, up to 300 mm depth
- BTA drilling range: 20 mm to 100 mm diameter, depths exceeding 500 mm
- Straightness tolerance: 0.05 mm per 100 mm of depth
- Oberflächengüte: Ra 1.6 μm achievable with optimized parameters
Our high-pressure coolant delivery systems maintain cutting temperatures below critical thresholds while ensuring complete chip removal from deep bores. This precision CNC approach eliminates deflection during drilling operations on extended workpiece lengths.
