older blades dressed as required based on the properties of the
sample material being cut. (See Maintenance: Blade Dressing.)
Cooling and Lubrication
Two different methods of applying coolant/lubricant are provided with
the ISOMET™ 2000 Saw. For most applications the self contained
recirculating system will provide adequate coolant flow. For optimum
cooling at extremely high cutting speeds with hard materials, the
ISOMET™ 2000 Saw can be connected to an external water supply
and drain. A water overflow protects the cutter in the event that the
drain becomes clogged or inadvertently closed. (See Accessories)
NOTE The unit's motor and recirculating system operate only when the cover
is closed. These machines have a water spray deflector built into the
hood, but if the cooling discharge water valve is opened too far, the
directional nozzles may force water between the hood and the top of
the cabinet. This water may well over the lip of the cabinet and run
down the sides of the machine.
Internal Coolant/Lubricant Recirculating System
When using the internal coolant system, fill the coolant tank with the
correct mixture of ISOCUT
® PLUS Cutting Fluid Concentrate and
water. The fluid level should be approximately 5.0 cm (2
″
) deep or 4
liters.
ISOCUT ® PLUS Cutting Fluid has been formulated for optimum cooling
and lubrication in medium and high speed cutting applications. It is a
water soluble concentrate which enhances the cooling properties of
water with effective lubrication and anti-corrosive properties.
ISOCUT ® PLUS Cutting Fluid promotes clean cutting with diamond
blades or abrasive wheels for faster, superior quality cuts. A flow
control valve is provided at the base of the coolant tubes to prevent
excessive coolant from over-flowing at the hood, etc. (See Accessories
and Supplies for part numbers.)
Internal Pump
The Plumbing Assembly contained in this unit is only used with the
internal coolant/lubricant system. (See Figure 3). When external
coolant is used, the plumbing will be modified. Instructions are supplied
with the Accessory kit.
Check and change the cutting fluid as required.
NOTE When using abrasive cut-off wheels with the ISOMET™ 2000 Saw, the
coolant tank should be cleaned frequently, not exceeding the life of 3
wheels. (See Maintenance Section.)
