Machining Head of Transfer Machines

Machining Head of Transfer Machines - Like many other types of special machine tools, the machining stations on transfer machines are often made up of unit heads, such as multi spindle drilling heads for example, the spindles of which are usually driven from a self contained electric motor through conventional reduction gearing.

The heads can be mechanically or hydraulically traversed along the slide ways while the cutting tools work upon the component.

In mechanical means, a cam or screw can be employed to traverse the head.

Mechanical writs are generally preferred:

(a) Where it is essential to maintain a definite chip per tooth on the cutting tool or maintain very accurate time cycles.

(b) Because they have a lower noise level, eliminate the possibility of hydraulic leaks,

(c) For longer tool life,

(d) As they can provide dwell functions and usually have built in torque limiting safety devices.

Hydraulically fed machining units

(a) May be preferred for rapid cycling.

(b) Have greater flexibility, since feed rates can be easily varied without the need for changing gears.

(c) Can be stopped during the stroke without damage in the case of jumps.
