STRONG BLADE SYSTEM.

TOOLHOLDERS FOR PARTING, UNDERCUTTING, GROOVING.

Blade 155.19-..-.

USING:

The toolholders – partings-off 155.19-..-. with changeable inserts PSN clamped toolholders by restoring forces are modern tools for parting objects with large diameters and for making depth radial undercuts.

The insert is fastened in the tool seat with a special key (155.19-KEY) by which the fastening surfaces are “unclenched”.

ADVANTAGES:

The position of the insert on two prismatic surfaces and one flat surface, and the simultaneous installation by using restoring forces ensure very good fastening stiffness, precision and repeatability, which guarantees durability of the changeable insert and the entire tool.

1. PTND and PTNn holders should be used for the fixing of the 150.19-..-., 151.19-..-., 155.19-..-. blades.

2. Ensuring a perpendicular position of the tool in relation to the axis of the machined object is one of the most important conditions of the correct operation of the tool – fig. 1.

    The cutting edge should be positioned at a height of +/-0,1 in relation to the axis of the machined object  (the position above the axis is more favourable) – fig. 2. 

Coolant should be strongly fed directly onto the cutting edge while machining.
