    Quality hydrualic cylinders options

    Prices are as follows, the parker brand cylinder is a 6.00-JJ2HLT14A-24.00 6" bore, 2.5" rod,3000 PSI 24" stroke. Parker = 3444.00 Milwaukee = 2245.40 Bosch Rexroth = 2666.70 Still waiting on quotes from Hanna Cylinders, seems a little out there to me for this hydraulic cylinder, I've rebuilt...

    Quality hydrualic cylinders options

    We have been using parker cylinders for our hydrualic needs for 10 years or longer, and I personally have always chosen them, because I knew they were a quality cylinder that I could trust to be problem free in the field. That being the case I know we pay alot for the name when we purchase them...

    Looking for a knife-edge splitting formula

    Thanks for input guys, the attached PDF is a blade style that produces decent results. I've seen and tested machines like these many years ago for production, and they did well. This machine will only be used for shearing/splitting pipe into smaller lengths so it can be re-ground and reused...

    Looking for a knife-edge splitting formula

    The blade will be ground from tool steel, the design is basically a hydrualic driven guillotine cutter. I have a ballpark idea of how much force would be needed, based on the largest length of blade contact x depth of cut x shear strength of HDPE. I may try to set up a test cut using a hydraulic...

    Cutting a Groove in a cylinder

    1.Make a new plane in the center of your shaft. 2.create sketch of profile on new plane. 3.Cut-revolve your sketch, using your existing axis.http://files.engineering.com/getfile.aspx?folder=ba062f3b-f42f-4503-a191-76c9599dd2a6&file=Part1.JPG

    Looking for a knife-edge splitting formula

    I've searched high and low to try and find a formula that would fall under this situation, with no luck. I'm trying to find the force required to push a knife edge blade through a piece of polyethlene pipe, like the hand held plastic pipe cutters. I know how to calculate the force required to...
