The goals of the present paper are to introduce truncated Lupaş type operators
of max-product kind and give an estimation for the degree of approximation with respect to
first modulus of continuity function. We prove that this estimate can not be
improved; on the other hand, for some subclasses of functions, better degree
of approximation is obtained. We also showed the piecewise convexity of the constructed operators on the interval [0,1].
