1. Introduction
Thank ou for purchasing a Specac product.
The Atlas™ Automatic (Auto) 40 Ton (40T) H draulic Press is an
automatic and programmable h draulic press which has been
designed for a wide variet of pressing applications within the
laborator or heav industrial environments, to appl a load up to 40
tons maximum. The press is specificall suited to the preparation of
solid sample discs using Specac evacuable pellet die assemblies, but
it ma also be adapted to provide heated pressing surfaces b
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
functionalit and can accommodate large samples up to 240mm wide,
220mm deep and 140mm tall. The press works b automatic motorised
pumping of a h draulic 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 assembl from where the oil is transferred across to
the base of the pressing area and forced under the piston assembl .
As the oil pressure builds up in the press s stem the load being
applied to the sample will be registered on the electronic displa . The
application of a load will continue until the required load is reached and
then held until released b the operator. Alternativel , the load can be
applied in a series of load stages via a specific program and
automaticall released from a programmed time hold function and
controlled release rate. The power unit is extremel 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 b 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 an load to the sample pressing procedure. In the
compression process the disc springs will be initiall compressed
before full resistance is met to stop the travel of the piston. When an
