B500 - Manual Component Saw with Digital Readouts.


The reliable, mechanical attributes of the DeSauw allow you to produce Consistently Accurate Components at Lower Labor Costs!

The DeSauw B500 is a solid saw! It is the heaviest saw on the market, and because of its physical attributes, it is sometimes referred to as being built like a tank. This makes the B500live longer, because its heavy framework absorbs the high-frequency vibration, which occurs during the cutting process.
The B500 gives the operator complete control of the setup process from one convenient location. Each of the Push-Button Controlled movements has a digital readout that shows the current position of the blades, as well as a backup, corresponding mechanical counter or scale on the saw.
This Extremely Reliable Component Saw is ideal for the small to midsize truss plant that requires a mechanically superior, time-proven reliable design. The DeSauw B500 excels in all areas, such as operator ease, versatility, durability, and return on investment.

Single Side Setup

The B500's Single Side Setup Controls are positioned, such that the operator may have every control for the entire saw in one convenient location, and within reach.

Swing Arm Panel

To increase the sawyer's productivity, the B500 is equipped with a Swing Arm Panel. It houses digital readouts, which display each blade's angle, vertical and horizontal position. There is also a digital readout, which displays the position of the Lumber Stop.

Operator's Control Panel

The Operator's Control Panel is in a permanent location at the in-feed conveyor. It houses the Lumber Counter, controls for Starting/Stopping the Blades, In-feed Controls, Hold-downs, and the Waste Conveyor.

Powered Carriage Board length is set by adjusting the moveable carriage. The carriage is equipped with a variable speed controller with an AC inverter drive.
This provides Speed Control with slow-speed fine-tune adjustment. A time delay provides an extra couple of seconds to use the fine tune knob. A full Length frame scale provides adjustment to 1/16th of an inch.
Automatic Position Lock keeps the moveable end stationary during cutting.

Horizontal Movement on the Front Quadrants

The Conveyor rails on the B500 are in fixed locations, so Horizontal Movement on the Front Quadrants allows an unused blade to be easily pulled out of the way and is quite useful in making square cutoffs.

Backup Mechanical Tracking

Mechanical counters & scales have been used on DePauw saws for 30 years. They have proven to be reliable and are a very accurate system of reading blade angulations. Other positions are tracked with scales and pointers. These mechanical tracking devices are used on the B500 for verification of the electronic digital readouts and reference during re-calibration.

Heavy Duty Wrapped Sprocket Design

Eliminates Chain lash and improves Multidirectional Accuracy.
The B500 utilizes direct-drive technology without chains and sprockets to adjust and less moving parts to lubricate. This method reduces lash and helps to ensure the extreme accuracy of your electronic digital readouts.
The Baldor saw-duty rated motors stand up to extreme forces such as high lumber feed rates and out-of-balance blades assuring maximum motor life and accurate cutting. The flat side shape of the motor housing allows longer cuts before breaking off the board.

Severe-duty signal encoders are oil/water proof, dust-tight, and are built on a substantial cast housing with heavy shaft bearings. All exposed wires are run in conduit. All encoders are directly coupled to the motors for accurate readings.

Calibration of Digital Readouts

The calibration panel is located on the side of the swing-away panel and allows re-calibration of the electronic digital readouts in a matter of seconds.

Duplicate Manual Setup Controls for Fixed End Blades

Setup Controls for Blades #1 - #5 are located on the Swing Arm Panel; however, Manual Setup Controls for Blades #1, & #2 are duplicated on the Fixed End Control panel.

Push Button Controls for the Lumber Stop (IN/OUT), an E-Stop Button, and the Fixed End Hold Down (UP/DOWN), are also located on this panel.

Heavy Duty Conveyors

The lumber conveyors are also similar to the rugged DePauw design. A gradual 30-degree incline promotes smooth material feeding. A direct drive system ensures consistent flight alignment.

A powered lumber stop is located on the fixed end of the saw but is controlled on the setup panel at the sawyer's station allowing quick setup during single angle cuts at the fixed end.

The operator guarding system self adjusts with different board dimensions and provides a safe area for the catcher, while allowing communication with the sawyer.

Blade Brakes

The Pneumatic puck-type brake was adapted from the machine tool industry. This pneumatic brake directly brakes the blade itself without creating any residual heat.
The lumber hold-downs are similar to the original rugged DePauw design. They're powered in sync with the lower conveyor chains, and they provide even pressure on the lumber; holding it firmly to ensure accurate cutting every time.
A sensor is located on the hold-down at the #5 location to prevent the 30¡¨ blade from crashing into the hold-down during angulation.

Additional Items:

An Aluminum Scarf Skid, and a Center Lumber Support are provided with the B500 to adjust for the natural sag of longer lumber.
