What You Will See in This Video
• 63mm U Drill in Action – Live cutting demonstration on thick component block
• Material Removal Rate – High MRR through optimized RPM, feed rate, and tool geometry
• Surface Quality and Hole Integrity – Precise hole formation without chatter or deflection
• Chip Evacuation and Coolant Flow – Flood coolant supports clean cutting edge and thermal control
Why Use a U Drill on CNC Gantry Milling Machines
• Faster Cycle Times – Achieve deep hole drilling in fewer passes
• Less Tool Wear – Indexable inserts optimize cutting edge contact
• Reduced Spindle Load – Balanced chip load per insert ensures longevity
• Consistent Hole Size – Maintains concentricity across the full depth of the hole
• Process Integration – Part of roughing sequence before finish boring or pocket milling
Applications of CNC Gantry Milling with U Drills
• Railways – Machining underframe structures, base plates, bogie support housings
• Energy Sector – Windmill flanges, hydro turbine brackets, generator bases
• Construction Equipment – Structural housings, weldments, crawler base machining
• Shipbuilding – Stern tube blocks, support ribs, long base machining
