Production > Tenoning Machines
|
|
Tenoning machines use cutter
heads and/or saw blades to form projections (tenons) on pieces of stock. Each tenon can be inserted
into a cavity (mortise) on another piece of wood to form a mortise
and tenon joint. The figure to the right shows a single-end tenoning machine. |

| Hazards/Solutions |
 |
|
Potential Hazards:
-
Point of operation - Contact with cutter
head or saw blade may occur.
-
In-running nip points - Clothing, hair, or
hands may be caught by and pulled into the
in-running rolls of the automatic feed.
-
Flying chips - Wood splinters and chips
may be thrown by the cutting action.
-
Kickbacks - Stock may be thrown back at
the operator after being caught by the cutter
head or saw blade.
|
Possible Solutions:
Engineering Controls
-
Enclose feed chains and sprockets of double end
machines, except for the portion of the chain
conveying stock [1910.213(k)(1)].
-
The cutting head and saws must be guarded with
metal guards. Cover the unused part of the
periphery of the cutting head. If an exhaust
system is used, the guard must form part of the
exhaust system [1910.213(k)(3)].
