Knowledge
What is CNC Drilling?
CNC drilling is a machining process that uses a rotating drill bit to create holes in a workpiece. As the drill bit cuts into the material, its cutting edges remove excess material, resulting in the desired hole. Our CNC drilling services can produce holes in metal or plastic parts based on customer-provided drawings, CAD files, or technical specifications. By selecting appropriate drill bits, configuring specific parameters, and planning the machining sequence, we can create a wide variety of hole types. Furthermore, we offer supplementary secondary operations, including boring, reaming, and tapping.

We have established a comprehensive quality management system covering IQC, IPQC, FAI, OQC, SPC, and CAPA. Supported by our in-house coordinate measuring machine (CMM), we conduct rigorous dimensional verification and inspection of machined features.
Hole Diameter & Geometric Feature Inspection
Control Standards: Through holes and blind holes are inspected according to applicable ISO 2768 general tolerances. Countersunk and counterbored holes are carefully checked for included angles and depths. High-precision H7 fit holes are achieved through precision boring or honing.
Inspection Methods: CMMs, precision pin gauges, and air gauges are used for 100% dimensional and geometric tolerance verification.
Positional Accuracy & Concentricity Control
Control Standards: True position and critical concentricity of locating pin holes are controlled to ±0.005 mm; positional accuracy of 5-axis machined hole features is maintained within ±0.01 mm; micro-hole accuracy on small components (less than 10 mm) reaches ±0.003 mm.
Inspection Methods: CMM measurements verify datum surfaces and deviations in hole-axis coordinates to ensure assembly alignment and repeatable fixture positioning.
Cross-Hole & Runout Inspection for Turned Components
Control Standards: We verify the concentricity and runout of center holes and eccentric cross holes located on outer diameters (OD) and end faces.
Inspection Methods: Taking advantage of the single-setup machining capability of turn-mill equipment, we use the turning datum as a common reference for runout and positional inspection, minimizing errors associated with secondary positioning.

Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.
How Accurate Is Xtmade's CNC Drilling Service?
Hole accuracy depends on the material, hole diameter, depth, tooling, and machining conditions. Xtmade evaluates these factors during the engineering review and selects suitable drilling and finishing processes to meet drawing requirements. For critical hole dimensions and positional requirements, we use CMMs and appropriate measuring instruments for dimensional verification.
Can Xtmade Machine Deep Holes and Complex Hole Patterns?
Yes. Our 3-axis, 4-axis, and 5-axis CNC machining centers support a range of hole configurations, including deep holes, angled holes, and multi-surface hole patterns. During process planning, we evaluate the hole depth-to-diameter ratio, tool accessibility, workpiece positioning, and chip evacuation requirements to determine an appropriate machining strategy.
What Is the Difference Between Drilling, Reaming, and Boring?
Drilling creates an initial hole in solid material, while reaming improves the dimensional accuracy and surface finish of an existing hole. Boring enlarges and refines an existing hole, offering greater control over its diameter and alignment. At Xtmade, these operations can be incorporated into the machining plan when a part requires tighter hole tolerances or specific internal geometry.
How Does Xtmade Ensure Hole Position and Dimensional Accuracy?
We review drawing datums, hole coordinates, tolerances, and workpiece clamping requirements before machining. For holes distributed across multiple surfaces, 4-axis and 5-axis machining can reduce repeated setups and help maintain positional consistency. During inspection, CMMs and suitable gauges are used to verify critical hole diameters, depths, and positional requirements against the drawing.
