Milling Titanium Ti6Al-4V with 8 cutting edges per insert!

Up to 8 cutting edges per insert. That’s helical milling at the lowest possible cost-per-edge. HARVI Ultra 8X helical milling cutters are designed to deliver the highest metal removal rates (MRR), especially in high-temperature alloys (Titanium).

Gundrilling Improves Accuracy of Medical Components

The Eldorado M75-30T is a twin-spindle gundrilling machine widely used for the manufacture of orthopedic implants, including femur nails and bone screws. The machine has greatly improved the accuracy of the components while also reducing the drilling cycle time.


The M75-30T has a 0.75-inch (19.1 mm) drilling capacity and a 30-inch (762 mm) drilling depth. It features two drilling spindles with independent spindle control, allowing two different drilling cycles at the same time. The machine also utilizes precision chucks and tailstock counter-rotation of the workpiece to improve drilling performance. Tailstock position is controlled via programmable servo to accommodate different part lengths.


The machine features a durable design that incorporates flame-hardened and ground cast iron box ways and hand-scraped spindle housings (versus linear guide ways and milled surfaces). This results in superior vibration damping, extended tool life, and improved hole accuracy and surface finish. Standard elements are also included on the M75-30T, such as a high-pressure coolant system, Beckhoff controls, and a full machine enclosure.


Eldorado gundrilling machines are built-to-order by Kays Engineering in their Marshall, Missouri facility. The Eldorado M75-30T will be on display at IMTS 2016 in Booth #S-8376.
