What is thermal deburr?

Thermal deburring (TEM) is a process of removing burrs caused by production (due to milling, drilling, etc.) from various machine parts. For this purpose, the workpieces are placed in a bell-shaped deburring chamber which is hydraulically closed by a closing plate.

What is a deburring machine?

What does a deburring machine do? A typical deburring machine contains one or more tools for smoothing burrs out of the machined metal. The orientation of the tools allows for consistent, quality deburring. Many deburring machines use brush, disc or belt heads for grinding burrs out of workpieces.

What is Thermal Energy Method?

The thermal energy method (TEM) process deburrs components by igniting a volatile gas mixture within a pressurized chamber containing the work piece gear. This creates a combustion heat wave that almost instantaneously reaches temperatures up to 3500°C that is then subsequently only sustained for a few milliseconds.

Why do we need deburring?

Deburring eliminates ease sharp edges so that the worker can handle it without the possibility of getting cut or injured because of it. Additionally, a deburring machine also helps to maintain the safety of other important machines.

What is electrochemical deburring?

Electrochemical deburring is a method that finishes the workpiece surfaces by means of anodic metal dissolution. The deburring tool is the cathode (-) that acts under DC current and in the presence of an electrolyte fluid to create the anodic reaction that removes workpiece (+) surface material in a precise. manner.

How is deburring done?

Mechanical deburring machines create abrasion imparted by an abrasive media placed together with the part inside a chamber. The chamber is agitated by vibration or tumbling. Thus, tumbling is a deburring process that uses abrasive media and the rotation of the chamber, known as a barrel, to scrape part burrs.

Why is deburring necessary?

When being cut, metals leave very sharp, rigid edges. Deburring eliminates ease sharp edges so that the worker can handle it without the possibility of getting cut or injured because of it. Additionally, a deburring machine also helps to maintain the safety of other important machines.

How is thermal energy measured?

Thermal energy can be described as the amount of energy a body stored due to its being at a higher temperature than its surroundings . It is measured using something called a calorimeter.

Which file is commonly used for deburring?

For deburring, you will need a single cut file. As you will only be filing edges, you will find that you can most often use a flat file for material of any shape. This process is known as ‘breaking the edges’.

How is electrochemical deburring different from machining?

Deburring is the process of removing the small imperfections known as burrs from machined metal products. Machining processes shape a piece of metal in different ways. Stamping, for instance, presses the workpiece in a die set, while milling uses a rotating tool to shave metal off a workpiece.

Why electrolyte is used in ECM?

The electrolyte has three main functions in the ECM process. It carries the current between the tool and the workpiece, it removes the product of the reaction from the cutting region, and it removes the heat produced by the current flow in the operation.
