1. Introduction
Thank you for purchasing a Specac product.
The Atlas™ Automatic (Auto) 40 Ton (40T) Hydraulic Press is an
automatic and programmable hydraulic press which has been
designed for a wide variety of pressing applications within the
laboratory or heavy industrial environments, to apply a load up to 40
tons maximum. The press is specifically suited to the preparation of
solid sample discs using Specac evacuable pellet die assemblies, but
it may also be adapted to provide heated pressing surfaces by
installation of Specac Atlas™ Heated Platens P/N GS15515. (Limited
to 15 tons maximum load.)
The Atlas™ Auto 40T press enables the controlled application and
release of an applied load via push button or programmable timed
functionality and can accommodate large samples up to 240mm wide,
220mm deep
and 140mm tall. The press works by automatic motorised
pumping of a hydraulic fluid (oil) to raise a piston and compress a
sample held in the pressing area. The press consists of a motor, pump
and oil reservoir assembly from where the oil is transferred across to
the base of the pressing area and forced under the piston assembly.
As the oil pressure builds up in the press system the load being
applied to the sample will be registered on the electronic display. The
application of a load will continue until the required load is reached and
then held until released by the operator. Alternatively, the load can be
applied in a series of load stages via a specific program and
automatically released from a programmed time hold function and
controlled release rate. The power unit is extremely quiet and operates
below 62 dB(A) making the presses ideal for use in all environments.
The sample is held in the pressing area prior to compression by use of
a lead screw and top anvil pressing face mechanism. Incorporated into
this mechanism are compression disc springs that allow for a slow
release of any load to the sample pressing procedure. In the
compression process the disc springs will be initially compressed
before full resistance is met to stop the travel of the piston. When any
