Tackling Large Billets With a Vertical Saw

Pryor, OK … HE&M Saw V750

With capacities of 75 inches wide by 25 inches high, the HE&M V750 vertical billet saw can tackle large billet sizes with relative ease. The HE&M V750 saw has features that greatly improve performance over traditional horizontal billet saws. The vertical saw design facilitates the loading and unloading of large billets directly from the front, a feature that is not possible on horizontal machines. Also, using a horizontal style machine for large billet sawing requires the guide arms to be opened very wide, decreasing the beam strength of the blade which can result in shorter blade life, greater opportunity for crooked cuts, and slower cutting. This problem is generally improved by incorporating wider blades to increase the blade beam strength. By utilizing the 3-band wheel design found on the V750, and by utilizing the vertical saw design format, the guide arms can be placed much closer together. This increases the beam strength of the blade without necessitating the use of a wider, more expensive blade. Sawing on a horizontal band saw that would require a 3⅛” blade can be accomplished on the HE&M V750 vertical machine with a 2” saw blade, greatly reducing the cost-per-cut.

The swing-away control console, with touch screen controls, is conveniently located on the front of the saw for mechanical and all electrical functions. This allows the operator to control the cut while seeing the progress clearly. The touch screen’s easy to use operator interface allows the saw’s operator to easily set up for semi-automatic cuts by choosing the material shape, cut depth and feed rate. Adjusting and controlling the vises, blade speed, cutting force, coolant and other functions can be done by touching the various keys on the screen before starting the cut. Various applications, such as viewing the patented Cut Watcher, laser light and computer controlled traverse are also controlled with the touch screen.

A camera on the backside of the cutting area shows a video feed on the console to allow better alignment of the saw blade to the material. A “Zero” key is available on the touch screen to set the position of the blade to return to when retracting after a cut. This allows for quicker set up when

making semi-automatic cuts on the same material.

The control panel includes informational screens that provide maintenance and diagnostic displays that are accessed by entering a security code. The touch screen control panel provides access to the encoders, diagnostic switches, and parameter settings for troubleshooting and setting up certain options for the saw. The saw’s running information such as blade life and band motor hours can be viewed at this screen. A blade break-in mode is available to be used after changing the blade to properly hone the blade so that it can be completely broken in before going into optimum cutting efficiency.

Input and output conveyor tables support and move heavy material into the cutting area smoothly and with ease. The input table is 10’ with 6” rollers on 12” roller centers; and the output table is 8’ with 6” rollers on 8” roller centers. The material is in-fed, aligned and discharged with a roller toggle switch located on the console that controls the rollers. After the material is in place, vise top clamps are used to secure the material for the cut.

In addition to the specialized features of the V750, all HE&M vertical saws have unique design qualities that improve performance such as having the motor and gear box mounted above the cutting area. This locates the power components above and out of the way of the sawing area, safe from metal chips, coolant, and other debris that are not compatible with the drive unit.

Cutting large billets, slabs, bars, or blooms with longer blade life and faster cut times are easily accomplished with this newly designed vertical V750 from HE&M Saw.
