Model No. 65B Circle Shear
We began offering a "B" version of the 3/8" / 10 mm capacity Circle Shear about 45 years ago. This machine (Model 65B) has a deeper throat than the standard Model 65 Circle Shear.
This machine is able to shear a circle from a square blank in one pass. By shearing a circle, then shearing another circle from the first circle, you have a ring. When making rings it is sometimes best to multi-pass the material depending on the cross-sectional width of the ring in order to maintain flatness of the ring.
The Model 65B has a 36" / 915 mm depth throat. If you need to cut rings then this deep throat machine will allow for rather large cross-sectional width rings.
The Model 65B Shear has a 10 HP Main Drive Electric Motor.
This machine has one Hydraulic Cylinder and one Pneumatic Cylinder.
The two Shear Blades (Upper & Lower) are made of tool steel. They have a diameter of 6" / 152.4 mm when new. As these Shear Blades wear they can be resharpened.
The Model 65B Shear is very fast. A 138" / 3500 mm diameter circle can be cut in about one minute.
Couple the Model 65B with a 3/8" / 10 mm Model 4 Flanger, (or a larger Flanger) and you are able to produce many flanged heads during a work day. Or, this machine can supply flat circles which can be dished on a Model 1625 (or larger) Head Dishing Machine.
