machine's foot and head are cut from the solid,
all bearing surfaces are mechanically machined
machine's columns are prestressed free from play
Pistons hardened and micro finished
bearing surface face grinded
Load measuring by electronic pressure transducer (DMS) on compression frame,
highly precise, shear force-insensitive load cell on bending frame
Compression test cylinder single acting; cut from the solid – no screwed-in bottom;
Testing Machine integrated in machine's foot
platens machined on all sides, hardened and on both sides face grinded
upper platen spherically seated to allow an inclination up to 3°
Straintest- upper platen spherically seated to allow an inclination up to 3°
Execution all transmission surfaces are additionally plane parallel treated and ultra-fine turned
EN 12390-4 universal ball joint in special execution, since the balance, the centrical force and
the blocking must be granted within prescribed limit values
ball plate suited in oil-bath
inclusive an extra calibration certificate for the Straintest
Bending test cylinder single acting; cut from the solid – no screwed-in bottom,
Testing Machine screwed to the machine's foot
bending table machined on the top-side and equipped with a T-nut,
in witch both bearings for the bending edges can be adjusted
below 2 adjustable bearings for the bending rollers,
1 bearing fix and 1 bearing tiltable seated.
The bending rollers are rotatable seated.
The bearings for the bending rollers are equipped with T-nuts,
which are for guiding and clamping of the bearings.
The bearings have marks, so that you can adjust the distance
between the bending rollers according to the measuring rule
at the bending table
the basic equipment includes the insert for 3-point load
Protective Grid around the compression testing chamber; on bending frame as option
absolutely necessary for "CE"-sign
on all sides pane made of macrolon, mounted on aluminium profile
profile frame door at the front side with pane made of macrolon
electric safety switch= the testing machine just works if the door is closed
