Abstract
To provide a laser machine allowing size reduction and space saving while guaranteeing a high degree of configurational freedom. A laser machine comprises: a numerical controller; a motor current controller that controls a motor; and a basic unit that supplies DC power to a laser excitation current controller that controls a laser excitation part. The basic unit comprises: an AC input part that receives AC power; an AC/DC converter that converts the AC power supplied from the AC input part to DC power, and supplies the DC power to the motor current controller and the laser excitation current controller; and multiple connection parts that connect the basic unit to the numerical controller, the motor current controller, and the laser excitation current controller mechanically and electrically.
Claims10
A laser machine comprising:
- a numerical controller that controls motion of an axis for moving a machining point and output of a laser beam;
- a motor that causes the motion of the axis;
- a motor current controller that controls a driving current for the motor;
- a laser excitation part that generates the laser beam;
- a laser excitation current controller that controls a driving current for the laser excitation part;
- a basic unit that supplies DC power to the numerical controller, the motor current controller, and the laser excitation current controller;
- one or both of a power supply regeneration part that feeds counter-electromotive force of the motor back into an AC input part, and a power generation part that recovers heat energy generated by laser machining and converts the recovered heat energy to electric energy;
- and
- a power storage part that stores power supplied from the power supply regeneration part and/or the power generation part,
- the basic unit comprises:
- the AC input part that receives AC power;
- an AC/DC converter that converts the AC power supplied from the AC input part to DC power, and supplies the DC power to the motor current controller and the laser excitation current controller;
- and
- multiple connection parts that connect the basic unit to the numerical controller, the motor current controller, and the laser excitation current controller;
- and
- communication means and power transmission means, the communication means establishing communication between the numerical controller, the motor current controller, and the laser excitation current controller, the power transmission means transmitting power from the AC/DC converter to the motor current controller and the laser excitation current controller, wherein
- the power supply regeneration part, the power generation part, and the power storage part are connected to the power transmission means, and
- the communication means further establishes communication between the power supply regeneration part, the power generation part, and the power storage part.
