USER GUIDE Setting Methods There are two optional setting methods - comparison REAMERS micrometer and setting device. Comparison micrometer with dial gauge, although a low cost solution and readily available for small workshops, is prone to damaging the cutting edge and therefore not recommended. Using a Comparison Micrometer Set the micrometer to the correct diameter using the precision blocks. Adjust the frontal diameter and back taper by turning the adjustment screw clockwise. The frontal diameter should be larger than the rear diameter by approximately 0.015 mm.(0.6 µin) Using a Setting Device ISCAR’s mechanical setting device enables easy, quick and accurate adjustment. Due to its modular construction, it can be used for standard, special and more complicated reamer adjustments. Setting Device Located Between Centers • Shorter setting time • Modular system • Higher accuracy • No risk of damaging the cutting edge H-REAM Cutting Conditions evaluated by examining the results and changing the The cutting conditions in the table below should machining conditions accordingly. be used to start a new application.
