90 Degree Angle Head Side Milling Head 12Nm Cross Milling Head Right Angle Head

AG90 BT50 ER11 90 Degree Angle Head CNC Milling Cutter Side Milling Head 1:1 Ratio 5000RPM. This AG90 BT50-ER11-80-70 90 Degree Angle Head is a precision-engineered machining accessory designed to convert vertical spindle rotation to horizontal orientation on CNC machining centers. Built from high-grade 40Cr alloy structural steel with full heat treatment, this angle head delivers exceptional rigidity, accuracy, and durability for demanding side milling, slotting, face milling, and contouring operations. The 1:1 direct drive ratio transmits the full spindle speed and torque to the cutting tool without reduction, ensuring maximum cutting efficiency. Featuring a precision-ground BT50 taper shank input and ER11 collet output, this angle head supports tool diameters up to 7mm for precision machining applications. The integrated 360-degree continuous rotation mechanism allows operators to position the cutting direction at any angle around the vertical axis, significantly expanding the machining capability of standard vertical machining centers. With a maximum rated speed of 5000 RPM and torque capacity of 12 Nm, this angle head is suitable for milling steel, aluminum, and various alloy materials in mold making, aerospace, automotive, and general precision engineering applications.

Net / Gross Weight. 4.9 kg / 8 kg. Product Features & Advantages. Precision BT50 Taper Shank. Precision-ground 7:24 taper for perfect spindle fit and ATC compatibility. Ensures stable, vibration-free cutting at 5000 RPM with minimal runout. Engraved scale ring from 0-350° allows precise angle setting. Enables multi-directional machining without repositioning the workpiece. ER11 High-Precision Collet Output. Accepts tools 1-7mm with excellent gripping force and runout accuracy. Dynamically balanced for 5000 RPM operation. 40Cr Alloy Steel Construction. Full heat-treated chromium-alloyed steel provides exceptional strength, toughness, and wear resistance under heavy cutting loads. 1:1 Direct Drive Transmission. Spiral bevel gears deliver 12Nm torque and 1.5KW power at 5000 RPM. Smooth, quiet operation with minimal backlash. Complete Professional Tooling Set. Includes ER11A spanner wrench, 17mm wrench, mounting block, pull stud, and storage case for immediate installation. Inspection: Check taper surface for damage. Verify collet chuck rotates freely. Confirm all accessories present. Install Pull Stud: Tighten BT50 pull stud to specified torque. Loose stud can cause disengagement during operation. Set Output Angle: Loosen lock screws, rotate to desired angle using scale. Mount in Spindle: Clean spindle bore, load angle head via ATC or manual. Verify full seating and drawbar engagement. Install Cutting Tool: Insert collet, tool, tighten nut with ER11A spanner. Machine: Set speed? 5000 RPM. Start with conservative parameters. Use coolant as recommended. After Operation: Stop spindle, remove angle head, clean taper, apply rust preventive oil. WARNING: Rotating machinery and sharp tools. Can cause severe injury. Trained Personnel: Qualified machinists only. Do not operate without proper training. Speed Limit: Do not exceed 5000 RPM. Excessive speed causes bearing and gear failure. Torque Limit: Do not exceed 12 Nm. Overloading damages gear train. Secure Locking: Ensure rotation lock screws are tight before machining. Loose head causes tool breakage. Pull Stud Tightness: Verify pull stud torque before each use. Loose stud can separate from spindle. Taper Surface: Keep BT50 taper clean. Minor scratches cause runout and vibration. Tool Installation: Ensure tools are properly seated and collet nut tightened. Loose tools can eject at high speed. Guards: Always operate with machine guards closed. Never reach into machining area while spindle rotates. Inspection Schedule: Check before each use for wear or damage. Stop immediately if abnormal noise or vibration occurs. Storage: Store in clean, dry environment. Apply rust preventive oil. Do not stack heavy objects on top. No Modifications: Do not disassemble or repair. AG90-BT50-ER11-80-70 Angle Head Main Unit 1.
