Overview of the 979-2 Miter Trim Saw System
KVAL model 979-2 Miter Trim Saw is designed to cut casing for doors and windows at rates up
to 25 pieces per minute for softwood material. Saws pivot between either 0- or 45-degree posi-
tions. The CNC index system will automatically compensate for cut length by adjusting the dis-
tance between saws.
The 979-2 saw heads cut down from above the face of the casing to eliminate any tear out on the
face.
There is also a chip-out support below the saw to prevent any deflection in thin casing as the saw
passes through it. This is especially important when cutting MDF casing, or pre-finished casing.
This design allows the scraps to drop below the machine into waste bins (Not included) without
assistance from compressed air nozzles. The air consumption of the 979-2 operating at maximum
capacity is only 8 CFM.
The 979-2 will miter side casing, with a 90 degree trim on the bottom, up to 98” long on the short
side of the miter. Head casing, mitered on both ends, can be cut as short as 12-3/8” measured on
the short side.
The feed hopper may be easily adjusted to accommodate material up to 4-1/2” wide and up to 1-1/
4” thick. The pieces of casing are fed from the hopper by a reciprocating dog system. The feed
dog systems on each carriage are tied together with a timing shaft to insure that each piece of cas-
ing is precisely positioned under the saws every time. Each cutting head is equipped with a 3 HP,
3450 RPM, TEFC, three phase motor. The saw motors have 1” diameter arbors.
Types of options available Are:
Option A: Spline Saw System
Cuts slots for kerf nail in head and leg casing miter.
Option B: Mitered ends on Door stop
Is capable of cutting mitered ends on door stop.
The Option G: Auto Calibrated Stops
Is an air operated system with calibrated stops that automatically adjust the movable carriage
when the saw heads are rotated.
Option Z: Computer Controlled Positioning
The 979-2 will be equipped with a computer driven servo motor to position the movable head.
The system will automatically compensate for the offsets when the cutting heads are switched
from 90 degrees to 45 degrees. The system will be controlled by a touch screen that will allow the
operator to simply enter the short side length of casing to cut. The finished length of the casing
will be correct for all saw head configurations.
