CN Columns

 

All CN columns are fabricated from parts made from high tensile steel. The conical coupling parts are precision machined from a high grade Chrome-Molybdenum steel combining low weight with strength and durability.

The female/male columns (F/M) are fitted with a female conical quick release coupling at one end, and a male coupling at the other end. 

 

To mount a column on a base plate or to join two columns, an eccentric bolt is inserted in the hole in the column, and tightened Clockwise with a ½” handle or ratchet.

 

To release the column, the eccentric is turned Counter Clock Wise until it lifts from the cone, the eccentric bolt is removed and the column can be removed.


Three types of CN columns are available:

a) F/J Columns with a female coupling in one end, and a Jack Screw in the other end. It can be extended only in the end with the female coupling.

b) F/M Columns with a female / male configuration, meaning that each column is fitted with a female conical quick release coupling at one end, and a male coupling at the other end. It can be extended in each end.

c) F/B Columns with a female coupling in one end, and a blanking plug in the other end. It can be extended only in the end with the female coupling.

The columns are available in four lenghts, 0.5 m, 1.2 m, 1.5 m and 2.0 m (20”, 47.2” 59” and 79”). The column with blanking plug in one end is available in 2.0 m length.

The columns, with the conical quick release coupling unlocked, can rotate around its own axis, and great flexibility is offered to simplify set-up.

An extendable column (F/M) can be joined with another column in both ends. It can be joined with as many columns as is needed for the job in question.
 
  Columns with a JackScrew (F/J) in one end, where the male coupling sits on an extendable column, can be used to jack the machine against ceiling or wall.
           
With the adjustable coupling the conical quick coupling can be swivelled sideways in increments of 5° for angular drilling operations.
 
  The columns fitted on the conical quick release coupling can be swivelled around its own axis. Great flexibility is offered to simplify set-up.
