Precision Engineering for Demanding TasksThe TOS OHA-12A is purpose-built for high-speed, high-precision gear shaping, making it ideal for workshops and manufacturing plants requiring consistent, accurate gears. Its rigid construction and integrated coolant system ensure smooth, reliable operation even under demanding conditions, while its flexible controls allow operators to handle a variety of workpieces with ease.
Versatile and Efficient Gear CuttingWith its automatic cycle operation and adjustable spindle speed (64 - 320 RPM), the TOS OHA-12A adapts easily to different gear sizes and types. It accommodates standard shank toolholders, has a wide range of feeds, and handles gears up to 125 mm in diameter. The combination of hydraulic and manual clamping further streamlines setup and ensures maximum stability during cutting.
FAQ's of TOS OHA-12A Auto-Cycle High-Speed Gear Shaper Machine:
Q: How does the TOS OHA-12A Gear Shaper operate?
A: The TOS OHA-12A operates using a gear-driven main spindle and semi-automatic mechanical controls. After securing the workpiece using hydraulic or manual clamping, operators set the cycle parameters. The machine then automatically performs the shaping process, using its integrated coolant and lubrication systems to ensure smooth and precise cuts.
Q: What types of gears can this machine cut?
A: This machine is suitable for both external and internal gear cutting, accommodating gear diameters up to 125 mm and modules up to 4 mm. It is commonly used for shaping precision gears required in automotive, machinery, and industrial applications.
Q: When is it beneficial to use an auto-cycle, high-speed gear shaper like the TOS OHA-12A?
A: Using the TOS OHA-12A is particularly advantageous when high production speeds and consistent quality are essential. Its automatic cycle function and high-speed operation enable efficient batch production, reducing manual intervention and downtime while enhancing repeatability and accuracy.
Q: Where is the TOS OHA-12A typically used?
A: This gear shaper is widely used in manufacturing plants, gear workshops, and by exporters, importers, and suppliers dealing in precision mechanical components. Its robust construction and versatility make it a reliable choice for both job shops and larger-scale gear production facilities.
Q: What is the process for changing gears or adjusting settings on this machine?
A: Change gears are included with the machine, allowing operators to adjust the ratio and achieve different gear profiles and feeds. The semi-automatic controls and multiple feed steps facilitate quick changes between different operations, enhancing productivity and customization.
Q: How does the integrated coolant and lubrication system benefit the operation?
A: The integrated coolant system cools the tool and workpiece during cutting, minimizing thermal deformation and tool wear, while the automatic forced lubrication ensures all critical components run smoothly. This results in longer machine life, improved accuracy, and reduced maintenance requirements.
