Model No. 45B Circle Shear


Picture
We began offering a "B" version of the 1/4" / 6 mm capacity Circle Shear about 45 years ago. This machine (Model 45B) has a deeper throat than the standard Model 45 Circle Shear. 

The 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 45B has a 30" / 760 mm depth throat.  If the cross-sectional width of a ring is very large, then you may need to consider the Model 65B which has a deeper throat. 

The Model 45B Shear has a 3 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 4 1/2" / 114.3 mm when new.  As these Shear Blades wear they can be resharpened.

​The Model 45B Shear is very fast.  A 120" / 3050 mm diameter circle can be cut in about 55 seconds. Couple the Model 45B with a 1/4" / 6 mm Model 3 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.
