Maintenance and calibration of the Profi 750 LZ lathe

Spindle calibration on Profi 750 LZ lathe

The photo shows a technician adjusting a lathe. Specifically, the technician is using a pressure gauge, to check the accuracy of a spindle or the alignment of a part. The pressure gauge is attached to a bracket that extends beyond a transparent plate, probably to protect the operator from chips and working fluids. Below the pressure gauge, the lathe chuck is visible, a rotating part that holds the work piece. The lathe is the “Profi 750 LZ” model from the Bernardo brand, known for its robustness and precision. The machine is well maintained with obvious signs of regular use. The lathe appears solid and stable, with several adjustment knobs and levers to control the movement of the spindle and other lathe components.

Precision measurement on Bernardo Profi 750 LZ lathe

In this image you can see an operator's arm who is carrying out a measurement on a lathe to calibrate or verify the dimensions of the machined piece. The lathe is equipped with a chuck, which is the part of the machine that rotates the work piece. The operator is using a dial indicator, a precision instrument that allows the detection of very small deviations compared to a standard measurement, for example in the order of hundredths or thousandths of a millimetre.

The machine in question, It can be noted that it is equipped with linear guides, visible in the lower part of the image, which serve to ensure the precise movement of the carriage and other moving components of the lathe. The guides are protected by transparent plastic covers that prevent chips and processing fluids from settling and causing wear or damage. Additionally, part of the lathe's LED lighting is also visible, providing direct light on the work area to improve visibility during measurement and machining operations.

Alignment check with level indicator on the lathe

In the photo you can see an operator who is using a level indicator to check or adjust the lathe. The indicator is mounted on a bracket positioned above the lathe spindle. The indicator reading is used to determine the precision of the workpiece or the alignment of the spindle itself.

Details of the Spindle and Controls on the Profi 750 LZ Lathe

Key details of the lathe are clearly visible, such as the chuck, which is the component that holds and rotates the workpiece. You can see a scale graduated in millimeters on one of the moving parts, indicating the machine's ability to carry out precision machining.

 Under the protection you can see the tool carriage, which holds the cutting edge and moves along the linear guides to make precise cuts.

The linear guides themselves appear robust and designed to ensure stability and precision in the movement of the carriage. There are also control knobs and levers, which the operator uses to adjust the rotation speed of the spindle and the position of the carriage.

The attentive technician manipulates a pressure gauge near the spindle. The scene shows his hands making precise adjustments, highlighting the lathe's detailed control knobs and levers. The video also shows the guides and the tool carriage, underlining the robustness and complexity of the lathe. The transparent protection adds a level of safety while the technician works, and the machine reflects an active industrial environment.
