Q2. What is the use of accumulator in tube mill
Ans. 
Accumulator in tube mill is used to store and regulate the flow of strip during continuous production.
• Accumulator helps in maintaining a constant speed of the tube mill by storing excess strip during high-speed operation and releasing it during low-speed operation.

• It also helps in reducing the number of welds required in the production process by allowing continuous feeding of strip into the mill.

• Accumulators can be of...read more

Q1. What is the lathe machine and their working function?
Ans. 
A lathe machine is a tool used for shaping materials by rotating them against a cutting tool.
• Lathe machines are used for turning, drilling, cutting, sanding, and knurling materials.

• They work by rotating the material on its axis while a cutting tool is applied to shape it.

• Examples of lathe machines include CNC lathes, engine lathes, and turret lathes.
