Precision Hole Drilling
We provide CNC hole drilling for components requiring accurate hole positions, controlled depth, and repeatable dimensions.
Our CNC machines follow programmed toolpaths to manufacture single holes, multiple-hole patterns, and complex mounting configurations.
Typical applications include:
-
Precision mounting holes
-
Bolt and fastener holes
-
Equipment installation holes
-
Oil passages and fluid channels
-
Alignment and locating holes
-
Repeated hole patterns on industrial components
Standard hole positioning accuracy is ±0.01 mm, with precision positioning down to ±0.005 mm for suitable fixture plate applications.
CNC Tapping and Threaded Holes
Keywin supports internal thread machining for components requiring secure mechanical fastening.
Our metric thread capabilities range from M2 to M64, while UNC/UNF thread specifications are available from #2-56 to 2.5"-4.
Drilling and tapping can be completed within the same CNC setup to help maintain hole alignment and reduce positioning errors.
Typical applications include threaded mounting plates, machinery housings, connection brackets, and equipment frames.
CNC Reaming for Precision Holes
When drilled holes require improved dimensional accuracy or surface finish, CNC reaming can be used as a secondary machining operation.
Reaming is particularly suitable for locating holes, alignment features, and components requiring a controlled hole surface.
Our published reamed surface roughness capability is Ra 0.8–1.6 μm, depending on the material, hole diameter, and processing conditions.
Deep Hole and Blind Hole Machining
Keywin supports custom drilling requirements involving blind holes and selected deep-hole features.
These applications require careful control of drilling depth, chip evacuation, tool rigidity, and coolant delivery.
Our engineers review hole depth-to-diameter ratios and material properties before determining the appropriate machining strategy.
