In this article we will talk about the restoration of the working surfaces (grinding) of the variator pulleys, but first we will tell you a little about what it is, a variator, and how it differs from the classic hydromechanical transmission. The main structural element of the variator is a V-belt transmission, it consists of 2 pulleys with dynamically variable the diameter of the cones and the belt that runs along them.
The animation shows the process of changing the gear ratio; any modern variator works according to this principle with minor design differences - for example, some manufacturers (Audi and Subaru) use not a pushing belt, but a pulling chain, but the principle of operation itself remains unchanged.
During the operation of the transmission, the surface of the pulleys is damaged, this can happen for many reasons: dirty oil starts to work as an abrasive material, start without heating (variators do not like starting off to a cold one, because cold oil does not perform its functions and the belt can slip, slip, unnecessarily high load (transporting a trailer or towing another car), breaking the belt. The problem is that new pulleys are not sold as spare parts, the manufacturer only offers the box assembly. We offer the option of restoring the pulleys, which consists in grinding the working surface on a high-precision circular grinding machine with CNC.
The photo below shows typical damage to the pulley, scratches on the surface and chips on the edge.
We use such a cylindrical grinding CNC
Installing pulley
Grinding. First, we make 2-3 passes and remove 0.01 mm each, then final grinding - 0.002 mm per pass.

We get the following result
Let's take a closer look, the surface is perfect, the edge is now chip-free.
This technology of CVT pulleys restaration has already been tested in operation on many cars and has shown its reliability.
