RATCHET
1. Cutting: flat steel is cut into the right shape using a machine; the accuracy of the
cutting ensures the minimum consumption of quality material.
2. Forging: forging parts are made using drop forging technology. Drop forging
allows diverse ergonomic product shapes. The appropriate course of the fibres,
already present in the rolled blanks, is maintained using the appropriate forging
processes.
3. Trimming: removing superfluous materials.
RATCHET CASING
4. Cnc working on a CNC machine is carried out using special clamping devices
that ensures the accuracy of the dimensions and functionality in terms of the
coordinated movement of all elements.
5. Heat treatment (quenching and tempering): heat treatment with hardening
and tempering is intended to improve the structure of the steel, to provide greater
hardness and toughness of the product and other properties required to overcome
the strains that work with this product requires.
6. Sanding: cleaning the surface before chroming is important for the sake of quality
and durable surface protection.
7. Chroming: the housing of the ratchet is plated with a thin, hard coating of
chromium oxide, which protects against corrosion and wear and other mechanical
damage. At the same time, it gives the entire product - the Unior ratchet - a brilliant
and professional appearance.
PINION
8. Cnc working is carried out on a CNC machine, which ensures the required
accuracy. The pinion is one of the essential elements of the ratchet and the
individual sizes have to be made within very narrow tolerance margins.
9. Teeth broaching is an operation for shaping the teeth on the pinion. The geometry
of 72 teeth guarantees the required two-sided shifting of the Unior ratchet.
10. Heat treatment (quenching and tempering):
heat treatment with hardening and tempering is intended to improve the structure
of the steel, to provide greater hardness and toughness of the product and other
properties required to overcome the strains that work with this product requires.
11. Sanding: cleaning the surface after heat treatment
12. Shift lever
13. Closing element
14. Shift button
15. Cover
16. Ejector pin
17. Assembly
18. Final assembly: the trained, skilled and meticulous workers performing the final
assembly will assemble the product into a whole that ensures the functionality and
high quality of the product.
