1 INTRODUCTION
1.1 MACHINE DESCRIPTION
Vertical single shaft milling machine, for machining wooden pieces by chip removal with
rotary tool installed on the shaft.
The machine has manual feeding, with a single vertical shaft, which can be fixed or in-
terchangeable, with fixed position during the machining and a horizontal supporting
plane, fixed during the machining. The shaft passes through the plane, and the driving
motor is positioned below. The machine can have one or more of the following configur-
ations:
•the possibility of choosing up to 5 rotation speeds for the tools depending on
their diameter and type of machining to be made;
•the possibility of adjusting the shaft in vertical position through the plane;
•the possibility of increasing the supporting surface by adding additional planes;
•motor direct starting by push button;
•the reversal of the shaft rotation direction;
•possibility of installing the interchangeable spindle.
1.2 CONFORMITY
The machine has been planned and built according to the norms ANSI 01.1: April 1991
SAFETY REQUIREMENTS FOR WOODWORKING MACHINERY.
