4680 20HP Horizontal Band ReSaw
Olivers Hydraulic Single Head Horizontal Bandsaw Resaw is driven by a powerful 20HP motor. Hydraulic blade tension, hydraulic feed works and pressurized hold downs are
just a few of the features that make this saw a cut above. As well, heavy construction and superior design mean this saw will stand the rigors of any shop environment.
The massive solid steel saw wheels are precision balanced to eliminate vibration. The saw wheels are designed heavy to increase momentum and allow clean cuts for even
the toughest conditions. The heavy duty return roller set has been added for operator convenience. Adjustable air cylinder over shock absorbing system keeps the material securely planted on the
conveyor table giving a superior cut. The air over hydraulic system automatically keeps the correct blade tension under different loads.
Weighted scrapers keep the saw wheel free of debris and residue build up. A fully adjustable oil mist system keeps the blade cool and lasting long. The hydraulic pump
and reservoir are conveniently located under the machine frame to reduce the overall footprint of the machine.
The conveyor feed works is driven by a powerful hydraulic gear motor allowing for more torque thereby ensuring constant feed, unlike a conventional electric motor in
this situation. The well laid out control panel is mounted on a swivel post for the operator. Included in the panel is a Digital Thickness Controller that automatically raises or lowers the blade
to the desired height. Standard off the shelf components are readily available at local supply houses.
A dual pressure roller system before and after the blade and the full width of the conveyor, ensures material stability as it goes through the blade. The well laid out
electric control panel uses off the shelf, readily available components. A soft start is included for the main motor. Fully adjustable blade guides with grooved thrust bearing keep the blade
running straight and true. Special guide material dissipates heat quickly. Linear bearing guides support the massive band wheels to ensure longevity and negate saw vibration.

4685 30HP Hydraulic Single Head Horizontal Bandsaw Resaw
Olivers 4685 Hydraulic Single Head Horizontal Bandsaw Resaw has 16 inch W x 10 inch T capacity and is powered by a 30HP motor. For convenience, a return conveyor is
added and a programmable controller automatically adjusts for cutting thickness. Conveyors and blade tensioning are both hydraulically controlled. This machine is highly accurate due to the
hydraulic blade tensioning and pressured hold down rollers.
The hydraulic tank is located under the saw frame to minimize the saw foot print and a radiator has been added to dissipate heat from the hydraulic fluid. Heavy duty
hydraulic gear motors power the conveyor feed works. OMP-250 for the infeed; OMP-160 for the return. The hydraulic system is powered off the band wheel. A flow regulator ensures proper flow of
fluid.
Smartly laid out electrical box with wiring diagram. Easily serviced with readily available off the shelf components from local retailers. A soft start has been
added for the main motor. Rear hold down pressure is assisted by an adjustable air cylinder/shock absorber system to ensure positive and accurate feeding. Ergonomic control panel is conveniently
located. Digital PLC controls the cut thickness through a 1/4hp, 6 pole motor that raises or lowers the blade. The PLC can be programmed for repetitive cuts of a fixed dimension at a push of a
single button.
Fully adjustable blade guides help dissipate the heat as well as keep the blade running true. Back-up thrust bearing is grooved to further assist in keeping the
blade true.
-
Full width rubber hold down wheels apply pressure directly before and after the blade to ensure stability at the cut point.
-
A fully adjustable oil mist system keeps the blade cool and prolongs blade life.
Air over hydraulic system automatically tensions the saw blade for varying loads and can be adjusted for width of blade being used. Front hold down pressure is
adjustable by an air cylinder acting with a shock absorber to securely hold the material to the conveyor ensuring a superior cut.
Massive 2-3/8 inch chrome steeled lift rods are guided through a 15 inch long housing to ensure rigid support of the band mill. Heavy duty rubberized conveyor
working with the rubber hold down rollers ensure positive feeding with no slipping even with extra wide and hard woods. Conveyor run/stop control is located next to the operator for safety and
convenience. Linear bearing guides support the massive band wheels to ensure longevity and negate saw vibration. Band wheels are machined from solid steel and precision balanced afterwards.
Driven by a 30HP motor the momentum created by the solid steel wheels allows for the cleanest cut with no ââ¬Ëbogging downââ¬â¢ on even the hardest of materials.
