Product FAQ’s
Q. What are the key technical specifications of gear hobs?
Key specifications include module, DP, pressure angle, helix angle, and number of starts. Outside diameter, bore size, and cutting length define tool capacity. Accuracy classes follow DIN or ISO standards. Material grade and coating determine tool life and performance.
Q. How much load can a gear hob handle?
Load capacity depends on hob material, module size, coating, and machine rigidity. Higher-accuracy hobs with proper coating can handle greater cutting forces and resist wear under continuous production. Multi-start hobs reduce cycle time but increase cutting forces. Proper parameter selection ensures safe and stable operation.
Q. Can gear hobs be customized?
Yes, gear hobs can be customized as per customer drawings and gear specifications. Customization includes profile correction, coatings, and special dimensions. Special hobs are made for non-standard gears. This ensures exact fit for specific applications.
Q. Do gear hobs meet international export standards?
Yes, STC gear hobs are manufactured as per DIN, ISO, AGMA, and customer-specific standards. Export tools are inspected for accuracy and material quality. Heat treatment and testing follow global norms. Compliance ensures acceptance in international markets.
Q. What is the load capacity of a gear hob?
• The load capacity of a gear hob depends on hob material, module size, number of starts, and face width.
• HSS and coated hobs handle moderate to high cutting loads, while carbide hobs support heavier loads.
• Proper cutting speed, feed rate, machine rigidity, and lubrication maximize safe load capacity.
Q. What drawings are required to manufacture a gear hob?
Gear drawings with module, pressure angle, and tooth details are required. Workpiece material and hardness must be specified. Machine details help optimize design. Clear drawings ensure accurate manufacturing.
Q. How are gear hobs installed on machines?
Gear hobs are installed by mounting them securely on the machine arbor or hob spindle with correct alignment and clamping. Proper concentricity and axial positioning are set to match the gear parameters. Cutting speed, feed, and depth are then adjusted as per the hob and workpiece material.
Q. What is the role of helix angle in gear hobs?
Helix angle defines the gear tooth inclination. It affects load distribution and noise levels. Gear hobs are designed to match helix requirements. Incorrect angles cause gear mismatch.
Q. Why is Super Tools Corporation recognized as a Top HSS Hob Cutter Manufacturer in India?
Super Tools Corporation is recognized as a Top HSS Hob Cutter Manufacturer in India due to its precision manufacturing and consistent quality. The company uses premium HSS grades and advanced production technology. Strict quality control ensures reliable performance in high-volume gear cutting. Global OEMs trust Super Tools Corporation for accuracy and durability.
Q. How does the gear hobbing process work?
Gear hobbing is a continuous cutting process where the hob and workpiece rotate in synchronization. The hob progressively forms gear teeth along the blank. This method allows high productivity and precision. It is suitable for both external and internal gears.
