SIRIUS PROFILE PROJECTORS Ø 500 MM HORIZONTAL PROJECTION

The Sirius model is characterized by a worktable set placed in front of the projection screen.
This model is fitted with same heavy duty 650x150 mm worktable with powered horizontal and vertical displacements of 300x200 mm. Taking into account its constructive principles of sturdiness, accuracy and reliability, the Sirius find its optimal use among tool makers and automotive manufacturers.

For the Sirius Model the special Version U/T dedicated for tools checking is available. To this purpose a dividing head for tool fixing can be used allowing to check the following features: profile – angle – diameter – rakes – chamfers – eccentricity – thread pitches.
