Case Study

Automotive Injector Nozzle Manufacturer Cuts Cycle Time by 41%

A Tier 2 automotive supplier in Poland needed to drill 0.35 mm fuel injector spray holes in hardened stainless steel at 58 HRC. Their existing process required pre-annealing, which added 90 minutes per batch. After purchasing an edm drill for sale from our 6 kW series, the plant eliminated annealing entirely. Using tungsten carbide electrodes and our adaptive pulse control, they achieved a hole roundness of 0.008 mm and cycle time reduction of 41%. Scrap fell from 6.2% to 1.4% in the first quarter, and the edm drill for sale unit now runs 22 hours per day with only routine electrode changes every 400 holes. The customer has since ordered a second edm drill for sale machine for their new production line.

Medical Device Maker Achieves 0.2 mm Holes in Cobalt Chrome

A Swiss medical instrument manufacturer required burr-free 0.2 mm guide wire holes in cobalt chrome alloy. Their previous laser process produced recast layers that failed fatigue testing. We supplied an edm drill for sale system with a 0.1 mm minimum electrode capability and deionized water dielectric. After parameter optimization, hole taper dropped to 0.005 mm, and fatigue life improved by 35%. The edm drill for sale machine has produced over 180,000 holes with a consistent wear compensation accuracy of 0.002 mm. The client reports zero field failures across 14 months of surgical tool production.

Aerospace Turbine Blade Shop Reduces Electrode Cost by 58%

A UK aerospace subcontractor drills cooling holes in nickel-based turbine blades. Their old edm drill for sale equipment consumed 12,000 electrodes annually. Our high-speed edm drill for sale model with automatic electrode changer and reverse-polarity circuitry reduced consumption to 5,040 electrodes per year, a 58% saving. Hole entry burr height stayed below 0.01 mm, and positional accuracy held at 0.004 mm across a 700 mm blade platform. The shop now uses the edm drill for sale machine for three shifts daily and passed a NADCAP audit with zero nonconformances related to hole drilling.

A recent batch of 15 edm drill for sale machines shipped to Italy showed zero geometric deviations above 0.005 mm after a 72-hour running test. Our machining department uses five-axis CNC centers to finish the spindle head and worktable, ensuring that every edm drill for sale unit meets the same standard regardless of destination.
Application-Specific Parameter Libraries for Faster Edm Drill For Sale Adoption

Application-Specific Parameter Libraries for Faster Edm Drill For Sale Adoption

Every edm drill for sale machine from our factory includes a preloaded parameter library covering 48 material and electrode combinations. This library was developed from over 3,000 real drilling tests conducted in our application center, where we simulate aerospace, medical, and automotive conditions. For example, drilling 0.3 mm holes in 62 HRC D2 steel uses our P27 program, which delivers a feed rate of 12 mm per minute and wear ratio under 0.28%. A US medical device customer used this library to produce 0.25 mm holes in cobalt chrome on the first day of installation, achieving a surface finish of Ra 0.5 µm without any trial-and-error. The edm drill for sale interface also allows operators to save their own programs and share them across multiple machines, which is common in plants with two or three edm drill for sale units. In high-mix toolrooms, this feature reduces programming time by an average of 40%.
