RH Series – Rack Hobbing Machine

Achieve next-level precision and high-efficiency performance in rack manufacturing with the CHARLES RH-1600 Rack Hobbing Machine, engineered explicitly for heavy-duty cutting and superior accuracy.

Features of Headstock

• Extended Service Life: All gears in the headstock are carburized by heat treatment and precision ground to ensure maximum durability.
• High Efficiency at Low Speeds: The spindle is driven by a wide speed motor, which provides high-efficiency machining even during low-speed operations.
• Heavy Load Resistance: High-capacity ball bearings used in the headstock feature a larger contact area, greatly enhancing resistance for heavier axial and radial cutting loads.

Quality Inspection & Rigorous Testing

To guarantee ultimate positioning accuracy and reliable field performance, every single machine undergoes strict international standard testing before delivery

• Dynamic Characteristics Testing for High-Speed Spindle: Conducted under various speeds to inspect and control dynamic balance, vibration, noise, temperature rise, thermal deformation, and high-speed rotation accuracy.
• Standard Mold Cutting Test: Every machine is subjected to a standard mold debugging cutting test to ensure the final output quality perfectly meets customer expectations.
• Ball Bar Testing: Executed according to strict ISO specifications to verify circular path performance and contouring accuracy.
• Laser Inspection: A dedicated laser unit is employed to inspect positioning accuracy and provide optimal compensation. We conduct 5 instances of back-and-forth inspection to collect comprehensive statistical data.

Various Spindles & Spindle Torque Output Diagrams

Each machining center from CHARLES comes equipped with a high-precision spindle, available in both #40 and #50 spindle tapers. To perfectly align with your specific machining requirements, we offer three types of spindle transmission methods:

• Belt Type Spindle BBT40
• Direct-Drive Spindle BBT40
• Built-in Type Spindle BBT40

Review our performance data charts—including configuration diagrams for βiI 8, βiI 12, βiI 15, αiI 8, αiI 12, and αiI 15—to match the exact torque output and motor speed required for your factory application.
