long throat windmill
The long-neck pneumatic end mill is a precise and lightweight tool for machining metals, engineering plastics, and composites in hard-to-reach areas. The overall tool length typically ranges from 120 to 200 millimeters, with the long neck measuring 60 to 120 millimeters. Shaft diameters are produced from 2 to 12 millimeters, and rotational speeds at 6 bar air pressure reach 18,000 to 32,000 RPM. Pneumatic motor power ranges from 0.3 to 0.6 kilowatts, allowing fast and precise material removal. The tool weighs between 0.6 and 1.5 kilograms, ensuring operator control during complex and long operations while minimizing vibration.
This end mill uses 3- or 6-millimeter collets with coaxial runout accuracy below 0.01 millimeters. Helix angles range from 25 to 40 degrees, and the number of cutting edges varies from 2 to 4, suitable for mild steel, aluminum, and engineering plastics. Bearing life with proper lubrication can reach up to 2,500 operational hours. Manufactured according to ISO 2768 standards, it guarantees quality and precision for aerospace, automotive, and mold-making industries.
