About Our Factory
Deep Hole Drilling Machine Manufacturer in China
RuidCNC is a factory-direct deep hole drilling machine manufacturer in Dongguan, China, with 25+ years of engineering experience. We design and build custom gun drilling machines, BTA deep hole drilling systems, and multi-spindle CNC solutions for mold & die, automotive, medical, aerospace, and energy applications — all ISO 9001 & CE certified.
What We Offer
Our Manufacturing Services
Mold & Die Deep Hole Drilling
Cooling channels, ejector pin holes, and deep hole features for injection molds, die-cast dies, and plastic molds — up to 1600mm depth.
Multi-Process Integrated Machining
Deep hole drilling, milling, tapping, and angular hole machining combined in a single setup — eliminates part transfers and reduces cycle time.
Complex Angle Deep Hole Drilling
Multi-angle deep hole drilling for complex workpieces with 5-axis positioning. Gravity-assisted chip evacuation for cleaner holes.
High-Volume Production Drilling
Simultaneous multi-spindle gun drilling for volume production. Auto-loading reduces labor and increases throughput.
Large-Diameter Deep Hole Drilling
BTA single-tube system for large-diameter deep holes where conventional gun drilling reaches its limits. Diameters up to Ø100mm.
Custom Engineering Solutions
Custom-designed deep hole drilling machines for unique applications — crankshaft oil holes, medical micro-drilling, and special geometries.

Gun Drilling Aircraft Hinge Pins: Ø2.45mm × 1,100mm in One Pass
Gun drilling aircraft hinge pins: Ø2.45mm × 1,100mm deep holes in a single pass (~450:1 ratio). From six twist-drilled pins a day to one finished pin every 30 minutes.
Deep Hole Drilling for Die-Cast Die Cooling Channels
Three-axis CNC machine drills straight cooling circuits to 1,600mm in hardened H13 die-cast dies, cutting die-cast cycle time by 23%.
5-Axis Vertical Deep Hole Drilling for Curved Airfoil Cooling Holes
Cradle-type 5-axis vertical machine drills multi-angle deep holes in curved airfoils in one clamping — 85% less setup time, no custom fixtures.
Testimonials
What Our Clients Say
Trusted by 500+ manufacturers across 20+ countries worldwide
"RuidCNC's 6-axis machine transformed our production line. The ability to drill, mill, and tap in a single setup cut our cycle time by over 50% and eliminated three secondary operations."
"We purchased a custom gun drilling machine for our crankshaft oil hole application. The engineering team understood our requirements perfectly and delivered a solution that exceeded our quality targets."
"After struggling with inconsistent hole quality from our previous supplier, we switched to RuidCNC. Their BTA drilling system gave us straight, clean holes with repeatable accuracy — and their after-sales support has been outstanding."
