This is a unit product of a tire testing machine used in automotive performance testing.
The tire testing machine is a testing device that verifies the durability of tires by running them on an outer circumference modeled after a road. Since the tests are conducted at up to 700 revolutions per minute, any runout tolerance can be extremely dangerous. Therefore, very high precision is required in the machining of the testing machine.
Our company has performed canning machining while considering runout during assembly, achieving a runout precision within 0.03mm. Additionally, it was necessary to apply electroless nickel plating to the outer diameter of φ3200mm, which is typically difficult for surface treatment processes, but we cleared the required specifications through collaboration with partner companies.
Togane Metal Industry can achieve high precision in large products like this one and in surface treatment processes that are usually challenging, thanks to our own technology and collaboration with partner companies.
