Precision Water Jet Cut 6061 Aluminum Frame for the Medical Industry

Putting our precision water jet cutting service to expert use, Rochester Technology and Manufacturing Association (RTMA) manufactures a 6061 aluminum frame used within a medical equipment application. In addition to water jet cutting carried out on our Jet Edge Model 55-100 multi-head water jet machine, we also use a Gardner double Disc Grinder SG-6 with oscillating feed to apply a fine finish to the frame. The outer frame of the part measures 5" x 6.5", with a thickness of 0.120". All four internal legs are 0.100" wide, with the outer two measuring 5.125" long and the inner two measuring 4.125". All dimensions are water jet cut to within a ± 0.001" tolerance.

The process involves one water jet cutting procedure for each part, cutting out the component in one single operation. The piece is then ground flat with a fine finish, to 63 RMS. We typically turn around an order in 10 work days, supplying our customer with 250 pieces per production run and manufacturing 2,000 of these frames per year.
