Q1. Which bearing used in CNC spindle? And why ?
Ans. 
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

Q2. What is Backlash?and how to check it ?
Ans. 
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

Q3. How many types of Hydraulic valve are there ? Diffenciate between pressure relief and pressure reducing valve.
Ans. 
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

Q2. Define the ohm law
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.
• Ohm's Law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• It is named after the German physicist Georg Simon Ohm w

Q1. What is voltage define it?
Ans. 
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
• Voltage is the force that pushes electric current through a circuit

• It is measured in volts (V)

• Voltage is the potential difference between two points in a circuit

• Higher voltage means more energy available to move electrons

• Voltage can be DC (direct current) or AC (alternating current)
