How To Use - Hitachi Koki CN16SA - 998030 Punch For CN16 Instruction Manual

6. Die inspection
Inspect for looseness of the M8 hexagon socket set screw used for mounting the die
holder, the
Fig. 4) and the M5 hexagon socket set screws used for mounting the punch (see Fig. 8).
Caution should be exercised because, if any of these screws are loose, not only does
cutting performance deteriorate but the machine can also be damaged.
7. Lubrication
Before use, carefully lubricate the sliding surfaces around the die and punch (see Fig.
1) with a suitable amount of machine oil or spindle oil.

HOW TO USE

CAUTION:
●
Never try to cut materials that are too large for the capacity of the machine since this
may cause damage.
●
Applying cutting oil (spindle oil, machine oil, and so on) along the shearing line may
decrease wear of the punch and die.
Use care to prevent cutting oil adhering to the housing since the surface may be
damaged.
1. Cutting plates
As shown in Fig. 2, hold the plates being cut parallel with the machine and apply a light
force while cutting. When pocket cutting, make a hole 29/32" (23 mm) in diameter or
larger, as shown in Fig. 3, and start cutting with the tip of the die holder.
2. Cutting corrugated and trapezoidal
plates
(1) The cutting direction of this machine can
be rotated in 90° increments in 3 directions
(A, B and C) (see Fig. 4) by loosening the
M8 hexagon socket set screw mounting the
die holder. Set the cutting direction in the
B or C direction to cut trapezoidal plates.
After that, securely tighten the M8 hexagon
socket set screw.
