Abstract
A mill system broadly comprising a cutting system and a substrate feeder system. The cutting system broadly includes one or more bases, a mill frame, a mill housing, a motor, a power supply, a rotatable shaft, and a mill head. The mill frame supports the mill housing and may be vertically adjustable on the bases. The mill housing houses the motor, the rotatable shaft, and the mill head. The rotatable shaft transfers power from the motor to the mill head. The mill head may be a cylindrical drum or similar shape and includes a plurality of teeth formed of diamond carbide or similar material. The teeth may be positioned in a helical pattern around the mill head for evenly removing material from the substrate and may have different effective lengths for creating grooves in the substrate.
Claims20
A mill system for effecting uniform thickness of a substrate, the mill system comprising:
- a cutting system comprising:
- one or more bases;
- a mill frame supported on the one or more bases;
- a mill housing attached to the mill frame;
- a motor;
- a power supply for driving the motor;
- a rotatable drive shaft rotatably coupled to the motor;
- and
- a mill head housed in the mill housing and rotatably coupled to the rotatable drive shaft, the mill head having a plurality of teeth for removing excess material from the substrate;
- and
- a substrate feeder system for conveying the substrate past the mill head and urging the substrate into contact with the teeth of the mill head.
(canceled)
A method of removing excess material from a substrate, the method comprising the steps of:
- providing a mill system comprising a cutting system and a substrate feeder system, the cutting system having a vertically adjustable rotatable mill head having a plurality of teeth;
- rotating the rotatable mill head;
- conveying the substrate via the substrate feeder system from a starting position towards the plurality of teeth to a finishing position so that the plurality of teeth removes a layer of excess material from the substrate as the substrate is conveyed to the finishing position;
- shifting the substrate back to the starting position;
- lowering the vertically adjustable rotatable mill head;
- and
- conveying the substrate via the substrate feeder system from the starting position towards the plurality of teeth to the finishing position at least a second time so that the plurality of teeth removes at least an additional layer of excess material from the substrate as the substrate is conveyed to the finishing position the at least second time.
A mill system for effecting uniform thickness of a substrate, the mill system comprising:
- a transport trailer;
- a cutting system comprising:
- a mill frame supported on the transport trailer;
- a mill housing attached to the mill frame;
- a motor;
- a power supply for driving the motor;
- a rotatable drive shaft rotatably coupled to the motor;
- and
- a mill head housed in the mill housing and rotatably coupled to the rotatable drive shaft, the mill head having a plurality of teeth for removing excess material from the substrate;
- and
- a substrate feeder system for conveying the substrate past the mill head and urging the substrate into contact with the teeth of the mill head, the substrate feeder system comprising a cart configured to be shifted along the transport trailer for conveying the substrate past the plurality of teeth of the mill head.
