Deep Hole Drilling Machine DK-30-400-L2
Place of Origin：China
Brand Name：CDK
MAIN CHARACTERISTICS
• High Efficiency: Inverted structure ensures excellent chip removal, efficiency 50% higher than vertical/horizontal deep hole drills.
• High Precision: Equipped with roller linear guides and ball screws (good rigidity); spindle uses precision angular contact bearings (high precision).
• High Surface Finish: Drilling roughness 0.8-0.4 (close to boring), better than ordinary drilling.
• Through-Spindle Coolant System: U-drill has through-spindle coolant; paired with high-pressure pump, coolant reaches working area directly—cools inserts, flushes chips, prevents scratches and boosts finish.
• Easy Operation: CNC-controlled with one-button start; no drill regrinding—only alloy inserts replacement, ensuring stable quality and lowering operator proficiency threshold.
• Low Failure Rate: Eliminates traditional drill gear structure, simplifies mechanics; overload protection in transmission part.
• Overload Protection: Real-time monitors spindle/feed torque, sets corresponding protection values by drill size.
