What is a TOS OHO 20 hobbing machine

The TOS OHO 20 is a shaper gear hobbing machine, a type of machine tool used mainly for the creation of internal gear hobbing on cylindrical pieces. Thanks to its robust construction and mechanical control system, it is ideal for the mass production of toothed components with high precision.

How to use it

The TOS OHO 20 gear hobbing machine is used for the production of internal gears. The machining process takes place using a tool (hob or knife) which performs a cutting movement along the axis of the piece. The workpiece is fixed on a chuck, while the tool performs the shaping movement in a controlled manner. The machine is adjustable to vary the number of strokes per minute, allowing the processing speed to be adapted to the type of material and the size of the piece.

Materials Used

This gear hobbing machine is designed to process mainly metallic materials such as:

• Steel : For resistant and long-lasting gears.
• Cast iron : Used for components that require good wear resistance.
• Aluminum alloys : For applications requiring low weight with good mechanical strength.

Main Industrial Sectors

TOS OHO 20 finds application in various industrial sectors, including:

• Automotive industry : Production of internal gears for transmissions.
• Precision engineering industry : Production of components for precision instruments and machinery.
• Tool industry : Production of gears for power tools and machinery.

Calculations and Formulas to Optimize Use

To optimize the use of the TOS OHO 20 hobbing machine, it is essential to take into account various processing parameters:

• Tooth Modulus (m) : m=dzm = \frac{d}{z} $m$ $=$ z d ​, dd $d$ is the pitch diameter of the piece and zz $z$ is the number of teeth.
• Cutting Speed ​​(V_c) : Vc=π⋅D⋅nV_c = \pi \cdot D \cdot n $V$ c ​= $\pi$ $\cdot$ $D$ $\cdot$ $n$ , where DD $D$ is the tool diameter and nn $n$ is the rotation speed in revolutions per minute.
• Strokes per Minute (CPM) : The regulation of strokes per minute (from 200 to 630) is crucial to adapt the processing to the type of material and production specifications, influencing the surface finish and precision of the piece.

Types of Similar Hobbing Machines

The TOS OHO 20 falls into the shaper gearing category. Other types of gear hobbers include:

• Hobbing machines : For external gears.
• Knife hobbing machines : For special hobbing.
• CNC gear hobbing machines : With numerical control for highly precise production.

Alternatives to HRT OHO 20

Alternatives to a shaper hobber such as the TOS OHO 20 can include:

• Milling machines with gearing accessories : For small productions or gears with unconventional shapes.
• EDM machines : For difficult to machine materials or complex shapes.
• Stamping : For mass production of simple gears.

Why It Is Better to Buy a Used TOS OHO 20

Purchasing a used TOS OHO 20 gear hobbing machine is advantageous for several reasons:

• Robustness and Longevity : TOS machines are known for their solid construction and long operational life. Even after years of use, they maintain high performance if well maintained.
• Reduced Cost : A used model offers significant savings compared to purchasing a new machine, while still maintaining high precision and reliability.
• Reliability : The TOS OHO 20 have been designed for continuous production and are able to withstand intense work cycles, making them an excellent choice even if purchased used.

In summary, the TOS OHO 20 hobbing machine represents an excellent choice for those looking for a reliable and precise machine for the production of internal gears, with the economic advantage of a used purchase that does not compromise the quality of the workmanship.
