10+ Bebitz Maintenance Engineer Interview Questions and Answers

To check machine backlash in a CNC machine, perform a backlash test by moving the machine's axis in both directions and measuring the difference in position.

• Perform a backlash test by moving the machine's axis in one direction and measuring the position

• Then move the axis in the opposite direction and measure the position again

• Calculate the difference in position to determine the backlash

• Repeat the test for each axis of the CNC machine

• Adjust the machine's backlash compensation...read more

A valve is a device that regulates, directs or controls the flow of a fluid by opening, closing, or partially obstructing various passageways.

• Valves are used in various industries such as oil and gas, water treatment, chemical processing, and power generation.

• They can be used to control the flow of liquids, gases, and even slurries.

• Valves can be manual or automated, and can be operated by hand, electric motors, or pneumatic actuators.

• Examples of valves include ball valves, ga...read more

A hydraulic pump is a mechanical device that converts mechanical power into hydraulic energy by generating flow or pressure in a hydraulic fluid.

• Hydraulic pumps are used in various applications such as hydraulic systems in heavy machinery, automotive brakes, and power steering systems.

• They work by creating a vacuum at the inlet, which draws in hydraulic fluid, and then pressurizing the fluid to generate flow or pressure.

• There are different types of hydraulic pumps, including ...read more

The lubrication system is responsible for providing lubrication to the moving parts of a machine to reduce friction and wear.

• It ensures smooth operation of the machine

• It reduces friction and wear on moving parts

• It prevents overheating of the machine

• It extends the life of the machine

• Examples include oil and grease lubrication systems

Machine parameters can be checked through various methods

• Use sensors to monitor temperature, pressure, and vibration

• Check for abnormal sounds or smells

• Inspect machine components for wear and tear

• Compare current readings to manufacturer specifications

• Perform regular maintenance and calibration

• Use software to analyze data and identify trends

Spindle bearing is a type of rolling-element bearing used to support a rotating spindle.

• Spindle bearings are commonly used in machine tools, such as lathes and milling machines.

• They are designed to handle both radial and axial loads.

• Spindle bearings are typically made of high-quality materials, such as chrome steel or ceramic.

• They are often lubricated with oil or grease to reduce friction and wear.

• The specific spindle bearing number refers to the size and type of bearing used...read more

To check bearing size, measure the inner and outer diameter and width of the bearing.

• Use a caliper to measure the inner and outer diameter of the bearing

• Measure the width of the bearing using a ruler or micrometer

• Refer to the manufacturer's specifications to confirm the bearing size

• Check for any markings on the bearing that indicate the size or part number

Hydraulic pressure is the force exerted by a fluid on an object due to the pressure of the fluid.

• Hydraulic pressure is created by a fluid, typically oil or water, being forced through a system of pipes or hoses.

• The pressure is measured in pounds per square inch (PSI) or bar.

• Hydraulic pressure is used in many applications, such as in hydraulic brakes, lifts, and machinery.

• The pressure can be controlled by adjusting the flow rate of the fluid or by using valves to regulate the ...read more

An axis is an imaginary line around which an object rotates or revolves.

• An axis is a reference line used to describe the position or movement of an object.

• It is commonly used in geometry, physics, and engineering.

• Examples include the x, y, and z axes in a three-dimensional coordinate system.

• In machinery, the axis refers to the direction of movement of a tool or workpiece.

• Proper alignment of machine axes is crucial for accurate and efficient operation.
