| The Press is deigned to accept various types of Dumb Bell and Sample Dies for cutting the sample. Description The Press can be used with various Dumb Bell and other types of dies to cut the sample from sample sheets. The press is designed to minimize the human effort required to cut the sample, by using the heavy wheel. When the operator turns the wheel, the wheel gains the momentum due to its weight and applies large force on the cutting die. . This type of cutting press is very simple and useful to operate especially for harder sample materials. The press can be installed on top of a table and operated by a single person. The Die cutter can be interchanged by just loosening one LN screw. |
