LATHE PARTS

LATHE PARTS

1. advance box: allow a range of transmission ratios with respect to the spindle, producing different speeds of rotation to the bar and therefore different advances

   • SPEED BOX: They are a series of sprockets mounted on three or more shafts, which are enclosed in a box and have a selector mechanism

2. SPEED BOX: They are a series of sprockets mounted on three or more shafts, which are enclosed in a box and have a selector mechanism

3. ADVANCE BOX: allow a range of transmission ratios with respect to the spindle, producing different speeds of rotation to the bar and therefore different advances

4. FIXED HEAD: it is in charge of supporting the plate that supports the body or object to be machined and that prints the adequate continuous rotational movement that is the main movement; which seeks to extract material in the form of chips with a cutting tool that operates peripherally.

5. MOVING HEAD: It is a tool or elements of the parallel lathe. It is a biconic piece, which is used in turning processes in long pieces.

6. BENCH: Serves as a support for the other units of the lathe.

7. SPINDLE: it is a tubular piece that has a pulley connected to one of its ends that receives the movement of the motor, and the plate is connected to the other end.

8. NORTON BOX: used to adjust the speed revolutions by means of levers that operate a set of gears found inside the box.

9. TOOL HOLDER TROLLEY: these are the trolleys that allow the cutting tool to be moved.

   • conta de 3 tipos de carros
     • MAIN TROLLEY: this moves along the bench, either to the left or to the right. It produces the advance movement of the piece, moving manually or automatically parallel to the axis of the lathe.
     • CROSS TROLLEY: moves forward or backward perpendicular to the main car. It is used to give depth. It is moved perpendicular to the lathe axis manually by turning the cross feed handle or engaging the automatic cross feed lever. On this carriage is mounted the adjustable carriage or auxiliary carriage.
     • AUXILIARY TROLLEY: it is a 360 ° rotating base and is mainly used to make tapers or penetrate the tool at a certain angle. The auxiliary carriage can only be moved manually by turning the screw handle to advance it.

10. MAIN AXIS AND PLATE: the part is placed on this axis to rotate. At one end it has a pointed shaft that is mobile, called tailstock, to hold the piece at one point, at the other end the piece is held with a plate. The plate can be changed by the spindle. The lathe has several plates for clamping of the piece to be machined and that will make it rotate around an axis. The piece is held by a one end through the plate and the other through the tip of the tailstock. The piece is placed on the plate and move the tailstock until it tightens the part.
