Gun Drill Spindle
150ZD20G3.7
Purpose-built spindle for deep hole gun drilling. 20,000 r/min, 3.7 kW, coolant-through-spindle. Max drill depth 1500mm. IP65 protected for wet machining environments.
150ZD20G3.7 Gun Drill Spindle
The 150ZD20G3.7 is a specialized spindle designed explicitly for gun drilling and deep hole machining operations. Работает на скорости до to 20,000 r/min with 3.7 kW of power, this spindle is optimized for the unique demands of deep hole drilling -- including high-pressure coolant delivery through the spindle, consistent feed force, and reliable operation during extended drilling cycles up to 1500mm depth.
The spindle приспосабливается к gun drills for hole diameters from 3mm to 25mm, making it suitable for a wide range of deep hole applications from small-diameter coolant passages to deep hydraulic manifold drilling. P4 precision angular contact шарикоподшипники provide the axial and radial жёсткость necessary to maintain hole straightness and diameter accuracy throughout the drilling cycle. The water-cooling system гарантирует stable thermal conditions during continuous operation, while sub-micron runout accuracy contributes to precise hole positioning and superior surface finish inside the bore. With защита IP65 for wet machining environments, the 150ZD20G3.7 is built to withstand the demanding conditions of deep hole drilling with high-pressure coolant. Housed in a 150mm diameter body and weighing approximately 42 kg, it интегрирует into dedicated gun drilling machines, CNC deep hole drilling centers, and custom deep hole machining setups for mold канал охлажденияs, hydraulic manifolds, automotive crankвал oil passages, and aerospace component drilling.
