CNC Drilled Components
Core Advantages
Finished Locating Bores
Drilled holes can be reamed as part of the machining route. Where a dowel or locating pin establishes an assembly position, the finished bore provides the specified seating diameter instead of relying on an unfinished drilled surface for the fit.
Recessed Fastener Seats
Countersinking and counterboring create dedicated seats for the specified screw heads. Where another component crosses the mounting surface, a correctly dimensioned recess keeps the fastener head within the permitted envelope rather than projecting into the adjacent assembly space.
Coordinated Hole Patterns
Multiple holes are machined against a common part datum. When a connecting plate joins two mating patterns, this controls the relationship of the holes to one reference rather than accumulating independent measurements from one hole to the next.


Customization Capabilities
We produce drilled components from the approved drawing or sample, using the specified hole function to establish the machining sequence. Drilling is followed by the required finishing operations, and thread or edge details are completed before final inspection.
Customizable Items
- Material: aluminum, carbon steel, stainless steel, copper or engineering plastic
- Hole diameter: Ø0.5–Ø50 mm
- Through-hole and blind-hole depth
- Hole count and center coordinates
- Metric or imperial thread designation
- Thread pitch and full-thread length
- Entry chamfers and edge breaks

Quality Control
- Incoming inspection verifies material identity, stock dimensions and hardness before the hole-making operations begin. The first-article check establishes the datum used to measure the pattern rather than accepting individual diameters as evidence of correct location.
- CMM measurement checks the drawing-defined centers and their relationships to the part. In-process sampling follows bore size and machining condition, with thread details and recessed features checked against their respective drawing callouts.
- Every part receives final appearance and key-dimension inspection. Entry and exit edges are checked for burrs, and holes are cleared of residual chips before packing; the resulting inspection records remain linked to the production lot.
FAQ
Q: What is the MOQ for drilled components?
A: The MOQ is 10 pieces; smaller quantities are negotiable.
Q: What is the lead time for custom production?
A: Custom production takes 10–15 days.
Q: Are full-thread depth and total drilled depth the same?
A: No. Specify full-thread length and the additional unthreaded clearance separately.
Q: Will a standard drilled blind hole have a flat bottom?
A: No. Specify an additional flat-bottom machining operation.
