Overview of the 979-2
The Kval Model 979-2 Miter Trim Saw is designed to cut door stops and casing materials up to 26
pieces per minute. Similar to a portable powered miter saw, the blades of the 979-2 cut from above the
work pieces through the material face to achieve the best quality possible with all types of moulding
materials, including pre-finished casing. Air consumption is just 8 CFM.
The hopper feed system accommodates material up to 4½ inches wide and from 12½ inches to 100
inches in length. The precision parallel feed system guarantees parallel indexing of work pieces under-
neath saw blades. Saw motors are three-phase, 3HP.
Saws pivot between either 0- or 90-degree positions. The CNC index system will automatically com-
pensate for cut length by adjusting the distance between saws.
Notable features of this machine are its touchscreen control panel and CNC index system.
All machine programming is done from the 979-2 operator's station touchscreen interface.
The touchscreen panel features on-board diagnostic screens that allow the operator to quickly and easily
identify the source of any errors or failures, even after they have occurred.
Operation Description
Trim material is placed in the hopper. The feed system then moves the material to the saws where the
end cuts are made. The material is then moved to the kerf saws (optional) and out of the machine.
