High-Precision Multi-Axis EDM Drilling For Medical Device Assemblies

A Titan 30 system with precision rotary indexing and custom multi-station fixturing for delicate, thin-wall medical components.

THE APPLICATION:

Micro-Features That Protect Life-Critical Performance

Miniature medical housings use radial cross-holes for fluid flushing, crimping, and sensor-lead routing. Each hole must intersect the center bore precisely without deforming the thin wall.

Titan engineered the process around titanium, stainless steel, cobalt-chromium, and nitinol while protecting the 32-microinch surface-finish requirement before passivation.

THE CHALLENGE:

Microscopic Features. Macroscopic Consequences.

01

Inner-Bore Clearance

A burr inside the narrow I.D. can block the functional path or interfere with internal components.

02

Radial Accuracy

Cross-holes must intersect the center bore at 90 degrees within a narrow axial land.

03

Thin-Wall Distortion

Mechanical cutting pressure can deform the outer cylindrical profile around the bore.

04

Surface Integrity

Manual deburring can scratch sealing surfaces and delicate outer flanges.

THE TITAN SOLUTION:

Machine, Motion, And Workholding Engineered Together

Titan paired a production-ready Force 30 with integrated rotary positioning, corrosion-resistant workholding, and automatic coordinate correction.

INTEGRATED FILTRATION + AEC

THE RESULT:

Consistent Micro-Holes Without Compromising The Component

The integrated process removes cutting pressure and manual alignment, delivering repeatable radial features while safeguarding inner-bore clearance and surface quality.

01

No Mechanical Distortion

Spark erosion produces the feature without applying cutting pressure to the thin wall.

02

Automated Repeatability

Probing and exact so-degree indexing correct alignment before every cycle.

03

Lifecycle Support

Calibration, dielectric service, wear parts, field engineering, and rapid repairs protect uptime.
