The Process of Manufacturing Precision Steel Blocks

TLDRLearn how precision steel blocks are manufactured through a meticulous process involving cutting, deburring, grinding, and EDM wire threading. This capability is crucial for producing molds used in plastic injection molding.

Key insights

⚙️Precision steel blocks are made by selecting steel, cutting it with a bandsaw, deburring, and then squaring it up and bringing it to size using a mill.

🔩Grinding is an important step in making precision steel blocks, requiring the use of a surface grinding machine with a coolant and deburring between grinds.

🧲A magnet holds the steel block on the table while the surface grinding machine is in operation, and a hose is used to wash away steel particles.

EDM wire threading is a crucial process in precision steel block manufacturing, which involves using a brass electrode to burn holes and threading brass wire that creates an electrical arc to burn away conductive material.

🌊The water used in EDM wire threading is deionized and the waste material is flushed away, making the process environmentally friendly.

Q&A

How are precision steel blocks made?

Precision steel blocks are made by selecting steel, cutting it, deburring, and grinding it to the desired shape and size. They are then threaded with brass wire using EDM technology.

What is the purpose of grinding in the manufacturing process?

Grinding is essential in manufacturing precision steel blocks as it helps to remove any sharp edges, bring the block to the correct size, and ensure its surface is smooth and uniform.

What is EDM wire threading?

EDM wire threading is a process used in precision steel block manufacturing. It involves using a brass electrode to burn holes in the block and threading brass wire that creates an electrical arc to burn away conductive material.

What is the role of the coolant in surface grinding?

The coolant used in surface grinding helps to cool down the grinding process, lubricate the grinding wheel, and flush away any debris or particles generated during the grinding process.

Why is precision important in the manufacturing of steel blocks?

Precision is crucial in the manufacturing of steel blocks as they are often used as molds in plastic injection molding. The precision of the blocks ensures the final product meets the required specifications.
