What is a ground part?

‍

In the industrial sector, all parts can be ground.

A ground part is a part that has undergone a machining treatment called "grinding". The treatment consists of removing material from the part using a grinding wheel to restore the desired size and shape. 

‍

A ground part is synonymous with precision, because a ground part is often used in applications with strict tolerances and requirements.

The grinding wheel is a machine used to machine materials. It holds a disc or strip of abrasive material in :

‍

• Corundum: capable of machining a wide variety of materials, including plastics
• Diamond: used when machining very hard materials such as ceramics
• Silicon carbide: used for hard materials such as steel.

‍

At LGC, we offer a range of different grinding wheel shapes, each with its own specific features:

‍

• Cylindrical grinding wheel: for flat surfaces
• Conical grinding wheels: for conical surfaces
• Flat grinding wheel: for flat surfaces

What is a ground cylindrical pin?

‍

The ground cylindrical pin is a pin has undergone a grinding process, enabling it to meet the requirements and standards demanded by our customers.

As this pin is used in very specific sectors with very strict requirements, grinding is carried out to the nearest micron.

For example, we can find a ground cylindrical pin to meet the needs of different fields of application:

‍

• On machine tools
• Measurement equipment
• Medical instruments.

‍

How is an LGC ground cylindrical pin made?

‍

The LGC method for manufacturing a ground cylindrical pin is similar to that for other pins, since the basic steps are the same:

‍

• Step 1: As with all all pinsthe first step is to cut the bars from the raw material, generally in the case of a ground cylindrical pin, the steel is stressed.
• The second step is a machining process called "turning". This involves turning the material to obtain the desired cylindrical shape.
• The third step is to carry out a treatment on the part, called "grinding", to obtain the desired smooth surface and adapt the part to the dimensions required by the customer.
• Step 4: As with the manufacture of all parts, LGC carries out quality control at the end of the manufacturing process, using high-tech measuring tools and the expertise of our staff (three-dimensional laboratory, 100% control machine, digital profile projector).

‍

Once these 4 stages have been completed, we ship the parts to the customer by the means of transport that requires the lowest possible CO2 emissions.

What are the advantages of a ground cylindrical pin?

‍

When we say "ground cylindrical pin", we're referring to both the DIN 6325 ground cylindrical pin and the ISO 8734 ground cylindrical pin. What's the difference between these two pins?

These two pins are identical, the only difference being their standard names: the DIN 6325 cylindrical pin conforms to the German standard, while the ISO 8734 conforms to the international one.

They may have different standard names, but their benefits are identical:

‍

• Aesthetics: The function of grinding is to improve the aesthetic appearance of a pin, providing a smooth, shiny surface.
• Precision: The precision offered by grinding guarantees precise positioning of the pin in the assembly.
• Resistance: After grinding, the cylindrical pin considerably increases its resistance to wear and friction, thus reducing maintenance requirements. Grinding also provides greater resistance to corrosion.
• Comfort: The smooth surface of the ground cylindrical pin reduces noise and vibration.
