Top 10 Questions for Reaming Machine Tender Interview

1. Explain the process of reaming a hole?

Reaming is a machining process used to enlarge or finish a hole that has already been drilled or cast. The process involves using a reamer, which is a cutting tool with multiple cutting edges, to remove material from the hole and create a smooth, accurate surface.

• The first step in reaming a hole is to select the correct reamer. The reamer should be the same size as the desired hole, and it should have the correct number of cutting edges for the material being machined.
• Once the reamer has been selected, it is inserted into the hole and rotated. The cutting edges of the reamer remove material from the hole as it rotates, creating a smooth, accurate surface.
• The reaming process is typically performed on a drill press or milling machine. The speed of the machine and the feed rate of the reamer are important factors in achieving a good surface finish.
• Once the reaming process is complete, the hole will be to the desired size and surface finish.

2. What are the different types of reamers?

Twist reamers

• Twist reamers are the most common type of reamer. They have a helical flute design that helps to remove chips and cool the reamer.
• Twist reamers are available in a variety of sizes and can be used to ream holes in a variety of materials.

Shell reamers

• Shell reamers are similar to twist reamers, but they have a larger diameter and a shorter flute length.
• Shell reamers are typically used to ream larger holes.

Adjustable reamers

• Adjustable reamers allow the user to adjust the diameter of the hole being reamed.
• Adjustable reamers are typically used for reaming holes to a specific size.

3. What are the factors that affect the accuracy of a reamed hole?

• The accuracy of a reamed hole is affected by a number of factors, including:
• The type of reamer being used
• The condition of the reamer
• The speed of the machine
• The feed rate of the reamer
• The material being machined
• The skill of the operator
• It is important to consider all of these factors when reaming a hole in order to achieve the desired accuracy.

4. What are the common problems that can occur during reaming?

• There are a number of common problems that can occur during reaming, including:
• Reamer chatter
• Reamer breakage
• Hole taper
• Hole bell mouth
• Hole out-of-roundness
• It is important to be aware of these problems and to take steps to prevent them from occurring.

5. What are the safety precautions that should be taken when reaming?

• There are a number of safety precautions that should be taken when reaming, including:
• Wearing proper safety gear, such as safety glasses and gloves
• Ensuring that the machine is properly guarded
• Using sharp reamers
• Reaming at a slow speed
• Using a coolant to keep the reamer and workpiece cool

6. What is the difference between roughing and finishing reaming?

• Roughing reaming is used to remove the majority of the material from a hole.
• Finishing reaming is used to create a smooth, accurate surface finish on a hole.
• Roughing reamers typically have a larger diameter and a shorter flute length than finishing reamers.
• Finishing reamers typically have a smaller diameter and a longer flute length than roughing reamers.

7. What is the difference between a reamer and a drill?

• Reaming is a finishing operation, while drilling is a roughing operation.
• Reamers are used to create smooth, accurate holes, while drills are used to create holes that are not as precise.
• Reaming is typically done at a slower speed than drilling.

8. What is the difference between a reamer and a tap?

• A reamer is a cutting tool used to enlarge or finish a hole, while a tap is a cutting tool used to create threads in a hole.
• Reamers have multiple cutting edges, while taps have a single cutting edge.
• Reaming is typically done at a slower speed than tapping.

9. What are the different types of materials that can be reamed?

• Reaming can be performed on a variety of materials, including:
• Metals
• Plastics
• Wood
• The type of material being reamed will affect the selection of the reamer and the cutting speed.

10. What are the applications of reaming?

• Reaming is used in a variety of applications, including:
• Automotive
• Aerospace
• Medical
• Electronics
• Reaming is a versatile process that can be used to create precise holes in a variety of materials.

Reaming Machine Tenders are responsible for operating and monitoring reaming machines, which enlarge or finish holes in metal workpieces. They ensure that the machines are properly set up and operated, and that the workpieces are produced according to specifications.

1. Machine Setup and Operation

Set up and operate reaming machines to enlarge or finish holes in metal workpieces

• Position the workpiece in the machine and secure it in place
• Select and install the appropriate reamer
• Set the machine to the correct speed and feed rate
• Start the machine and monitor its operation

2. Inspection and Measurement

Inspect and measure workpieces to ensure that they meet specifications

• Use precision measuring instruments, such as micrometers and calipers
• Compare the workpiece dimensions to the engineering drawings
• Make adjustments to the machine or workpiece as needed

3. Machine Maintenance

Perform basic maintenance on reaming machines to keep them in good working order

• Clean and lubricate the machine
• Replace worn or damaged parts
• Follow manufacturer’s maintenance instructions

4. Safety

Follow all safety procedures to prevent accidents and injuries

• Wear appropriate safety gear, such as gloves, safety glasses, and earplugs
