The plasma cutting machine of the invention includes a constant height plasma cutter, a rolling table and cutting system support. The plasma cutter and the rolling table are supported by the cutting system support. The rolling table is adapted to be positioned on the cutting system support at a loading position at a cutting position. The cutting position is beneath the plasma cutter.The plasma cutting system of the invention optionally includes an additional rolling table. Each rolling table includes adjustable pins supported on transverse channel members.
In the plasma cutting system of the invention the constant height cnc plasma cutter is carried by a gantry driven from opposite sides. The rolling table is loaded in a loading position where the operator positions metal sheets thereon. The operator then rolls the loaded table to a cutting position beneath the plasma arc cutter. The plasma arc cutter is held at a constant height above the rolling table. Each metal sheet loaded onto the rolling table is supported on the adjustable pins. The entire cutting area is enclosed and vented thus protecting the operator from fumes produced during cutting.
In the plasma cutting system of the invention a cutter housing supports a transparent curtain, and the transparent curtain encloses the plasma cutter. A gantry is supported by the cutter housing, and the gantry supports the plasma cutter. The rolling table is adapted to be positioned on the cutting system support at a loading position and at cutting position. The cutting position is beneath the plasma cutter. The rolling table includes a table frame, adjustable pins and table wheels. The adjustable pins and the table wheels are connected to the table frame. The adjustable pins extend above and below the pin supporting channels of the table frame. The cnc plasma cutting machine includes a constant height plasma arc cutter and a cutter positioner. The plasma arc cutter includes a plasma arc cutting portion and a programmable cutter control. The cutter position includes a cutter support and a programmable cutter position controller. The cutter support includes a gantry and a rotatable pinion at each end of the gantry.
