Let Titan Solve Your Production Challenges
Bring your part geometry, material, tolerance, and throughput requirements to Titan EDM’s application engineering team.
A full-table batch process for deep, concentric cooling and vent passages in hardened core pins—after heat treatment.
Core pins form cavities, threads, and undercuts in molded parts. Internal cooling or vent passages help control cycle time and quality— but are difficult to drill in fully hardened steel.
Titan replaced fragile mechanical drilling with non-contact EDM and replaced one-at-a-time setup with a full-table V-block workholding grid.
Drilling at 50 to 62 HRC causes cutter wear, work hardening, and breakage.
Aspect ratios from 20:1 to 50:1+ push mechanical micro-drills off center.
Contoured pin tips make mechanical drills skid before a stable cutting path.
Single-part collet setups create high labor cost and a major throughput bottleneck.
Titan integrated an iSeries machine, automatic probing, electrode management, and a corrosion-resistant full-table fixture around the complete pin range.
Non-contact EDM creates deep passages in fully hardened material without cutter wear or entry skidding.
A 420 stainless fixture holds pins from 0.062 to 1.000 inch in parallel alignment.
A multi-point probing macro scans each pin and updates the work coordinate system before drilling.
The iSeries combines fast-hole EDM performance with the flexibility needed for a varied part family. Titan’s fixture and probing logic let the machine find, align, and process every pin as a batch.
The cell makes it practical to finish and heat the pins before hole making, while batch workholding and probing keep the process productive across diameters and positions.
Cooling holes are created after final hardness, avoiding later heat-treatment distortion.
Non-contact drilling helps maintain concentricity across long, small passages.
Operators load many pins and let probing, selection, and drilling proceed automatically.
