The horizontal measuring arm of the LY90 T series is structurally designed with a guide on a granite table. Compared to the HC90 series, the machine is made of aluminum materials. This type of machine is less accurate, but its acquisition costs are lower.
The horizontal measuring arm of the LY90 T/TR series is suitable for measuring large components in the automotive and aerospace industries. Unlike many HC90 R/TR machines, LY90 machines are made of aluminum materials and do not achieve such accuracy. The slides are made of granite material and laid loosely on the floor in the measuring rooms. The LY90 R series indicates single-column and LY90 TR two-column versions.
