Jbm Auto Components Mechanical Engineer Interview Questions and Answers

Angular contact ball bearings are commonly used in CNC spindles due to their ability to handle both radial and axial loads.

• Angular contact ball bearings are used in CNC spindles because they can handle both radial and axial loads efficiently.

• These bearings provide high rigidity and accuracy, which are crucial for CNC machining operations.

• The contact angle of angular contact ball bearings can be adjusted to optimize per...read more

Backlash is the amount of clearance or play between two mating components in a mechanical system.

• Backlash is commonly found in gear systems, where it can affect the accuracy and efficiency of the system.

• To check backlash, one can use a dial indicator to measure the amount of movement between the components when they change direction.

• Backlash can be adjusted by tightening or loosening the components to reduce the cleara...read more

There are various types of hydraulic valves, including pressure relief and pressure reducing valves.

• Types of hydraulic valves include directional control valves, flow control valves, pressure control valves, and check valves.

• Pressure relief valves are designed to limit the pressure within a hydraulic system by diverting excess fluid when the pressure reaches a certain level.

• Pressure reducing valves, on the other hand, ...read more
