Gear Hobbing Machine: High-Precision Industrial Gear Manufacturing Solution
The Gear Hobbing Machine is a heavy-duty, high-precision machine tool designed for the efficient production of cylindrical spur gears, helical gears, worm gears, and spline shafts. Built for industrial-grade reliability, it is widely used in automotive, aerospace, heavy machinery, and general mechanical manufacturing industries. This machine offers exceptional structural rigidity, stable performance, and excellent repeatability, making it ideal for both batch production and small-batch, high-precision manufacturing. All machining processes comply with international gear manufacturing standards, such as ISO 21771-1, to ensure consistent precision and reliable results for industrial applications.
Main Performance and Structural Characteristics
- Rigid & Stable Structure: The machine tool is mounted on a heavy-duty bed with a large column, with the worktable moving both horizontally and radially for high-precision positioning.
- Versatile Machining Capability: Supports both up and down milling operations, and features a manual hob shifting device for flexible gear machining.
- Vibration-Free Axial Movement: A pressure balance oil cylinder eliminates screw-nut backlash, effectively suppressing vibration caused by cutting forces during the tool post’s axial movement.
- High-Efficiency Hydraulic Worktable: The worktable is hydraulically driven, with a 50mm rapid approach/exit mechanism to significantly reduce non-cutting auxiliary time.
- Adjustable Rear Column Support: A manually controlled hydraulic three-position valve allows the outer support of the rear column to lock securely at any desired height.
- Flexible Speed & Feed Adjustment: Spindle speed and axial feed rate are controlled via a combination of manual shifting and exchange gears. Both split and differential gear transmission chains use exchange gears for versatile adjustments.
- Durable Indexing Worm Gear: The high-precision indexing worm gear pair is made of bronze alloy, offering excellent wear resistance and long service life.
- Precision Ground Transmission Gears: High-precision ground gears ensure accurate power transmission with minimal noise during operation.
- Premium Rolling Bearings: Key components in the main shaft and transmission chain use high-precision rolling bearings for smooth, reliable performance.
- Accurate Manual Tool Post Rotation: The tool post’s manual angle adjustment uses a self-locking worm-and-worm gear structure for precise, repeatable readings.
- Controllable Cooling System: A dedicated cooling pump delivers coolant to the tool post via a delivery pipe, with a nozzle-mounted switch to easily adjust coolant flow rate.
- Semi-Sealed Protection & Chip Management: The semi-sealed machine enclosure prevents coolant leakage, while iron filings are collected in a dedicated box for easy, regular removal.
