rolled spindles
Thread rolling or thread rolling is a non-cutting manufacturing process. So it is a cold deformation. At least 1 roller carriage generates the feed to penetrate the workpiece. At the same time, the tools roll off the workpiece by rotation. The thread geometry is reproduced on the raw part through the profile of the tool.
We manufacture both in the grooving and in the continuous process.
Advantages of this procedure:
- Economical manufacturing
- Uninterrupted grain of the workpiece material
- Press-polished thread flanks
- Higher wear resistance
- Reduced notch sensitivity
- Higher flexural fatigue strength
- Improved tensile strength
- Better corrosion resistance
whirled spindles
Thread whirling is a metal-cutting manufacturing process. In the whirling process, the thread profile is created using a ring-shaped tool with inwardly directed cutting bits.
Advantages of this procedure:
- high precision
- The tools are independent of diameter, profile and pitch
- All machinable materials can be used
- Inexpensive for small batches
- Low tool costs
- Optically higher quality surface than with thread rolling
- Spindle lengths greater than 6 meters can be produced
cut / turned spindles
Thread cutting or thread turning is a metal-cutting manufacturing process. With thread cutting, the thread profile is introduced with a die, with thread turning with an indexable insert
Advantages of this procedure:
- Economical for large quantities, especially in combination with other turning and milling operations
- All machinable materials can be used
- The tools are independent of diameter, profile and pitch
ground spindles
Thread grinding is a cutting manufacturing process. The tools used for the grinding process are grinding wheels, the grinding surface of which consists of a layer of grains. Different abrasive grains are used depending on the nature of the workpiece. It is the classic manufacturing process for machining threads in hardened material. However, due to the long processing times, this process is costly. Grinding is also used for precision trapezoidal screw drives that are required in a hardened version.
Advantages of this procedure:
- Extreme profile, pitch and shape accuracy
- Hardened materials can also be processed
- Low surface roughness
- Optically higher quality surface
- Spindle lengths greater than 6 meters can be produced
