• Maximum Torque: 34 Nm
• Gear Ratio: 1:1
• Orientation: 360° Manual Adjustment
• Origin: Made in the United Kingdom by Centreline (CTL)

Key Performance Features

• Superior Rigidity: Features an integral drive shaft and high-precision spiral bevel gears. These gears are hardened and ground to ensure maximum power transmission with minimal vibration and noise.
• Compact High-Power Design: Despite its 9.3 kW rating, the TCL series maintains a streamlined profile to allow for machining in tight bores and complex internal geometries.
• Advanced Thermal Management: Engineered to withstand the heat generated by 7,000 RPM continuous duty cycles. The high-quality bearing arrangement ensures long-term spindle accuracy and minimal thermal growth.
• Versatile Mounting: Designed to be compatible with most standard CAT50 machining centers. (Note: Requires a standard or custom stop block for installation).

Primary Mounting Dimensions

• Location Pin Center Distance: The most critical dimension for mounting to your machine's spindle face (stop block). Standard options for the TCL series are:
• 80 mm (Common for standard CAT50/ISO50)
• 100 mm
• 110 mm (Heavy-duty standard)
• Location Pin Diameter: Typically 18 mm or 20 mm (tapered pins are standard for CTL to ensure maximum rigidity).
• Shank Taper: CAT50 (7/24 taper) with standard pull stud threads.
• Body Diameter: Approximately 120 mm to 124 mm (designed to maintain a slim profile for bore entry).
• Reach (Gauge Line to Spindle Center): Standard length is typically around 160 mm to 200 mm, though "Extended" versions are available at 240 mm, 280 mm, or up to 800 mm.

Technical Integration Details

• Orientation Pin Height: The pin is usually adjustable or spring-loaded to engage with the Stop Block on the machine spindle nose.
• Automatic Tool Changer (ATC) Compatibility: The TCL series is generally equipped with a "V-Groove" and spring-loaded interlock, allowing it to be swapped by the machine's ATC if the weight (approx. 8.5 kg to 12.3 kg) is within the machine's limit.
• 360° Adjustment: The head can be manually rotated 360° relative to the shank, allowing you to align the 90-degree output to any radial position.
