Cylinder honing tools are used to polish engine cylinders, increasing durability and ensuring better vehicle performance.
Read this article to find out the main advantages of using this piece of equipment and the best options of cylinder honing tools for your garage.
Why do cylinders need to be polished?
To ensure that the inner surface of the cylinder is kept even and smooth, honing your engine cylinders removes minor irregularities or marks on the cylinder surface that can affect engine efficiency.
In addition to causing increased friction between the piston and cylinder, irregularities on the cylinder surface can trap dirt or carbon particles, which can damage pistons or piston rings.
By polishing your engine cylinders, you ensure that the inner surface of the cylinder is levelled and smoothed, reducing the friction between the piston and cylinder and helping prevent damage to the piston and piston rings.
The result may even be improved engine efficiency, increased engine service life, and reduced long-term maintenance costs.
In addition, polishing cylinders will contribute to fuel savings and reduced polluting gas emissions.
What is a cylinder honing tool?
Cylinder honing tools use a whetstone mounted on a rotating shaft, which is then inserted into the cylinder to polish it.
Whetstones used for this purpose are made of abrasive material, such as aluminium oxide, which is mounted to fit the diameter of the cylinder that needs polishing.
What are cylinder honing tools used for?
Cylinder honing tools are used to remove the surface layer of cylinders within internal combustion engines.
The process aims to improve the uniformity of the cylinder’s internal diameter and remove imperfections on the cylinder surface, such as scratches, wear marks, or material deposits.
Which types of cylinder honing tools are there?
There are two main types of cylinder honing tools: manual and automatic.
Manual cylinder honing tools
Manual cylinder honing tools are portable tools used to polish cylinders individually. This type of tool is generally more affordable than an automatic tool but requires more skill and physical strength to operate.
Automatic cylinder honing tools
Automatic cylinder honings tools are used for large-scale cylinder polishing, as they are more accurate and efficient than manual tools. You can even programme them to perform several different polishing processes.
How do cylinder honing tools work?
Work with a cylinder honing tool starts with preparing the cylinder, which usually involves cleaning its surface and measuring its diameter.
Next, the whetstone is mounted on the tool’s rotating shaft, which is adjusted to fit the diameter of the cylinder.
Turn the tool on, and the whetstone should start to rotate rapidly.
The operator should then move the tool along the length of the cylinder, applying consistent pressure so that the whetstone can remove the cylinder’s surface layer.
Once the surface of the cylinder has been polished, the operator should clean the area to remove any abrasive material residue that may have built up on the cylinder surface.
Why is it important to have a cylinder honing tool?
It’s essential for any garage to have a cylinder honing tool because it allows mechanics to polish engine cylinders efficiently and accurately.
Having a tool that does this means that mechanics can offer quality engine tuning and other services, as they are able to polish components accurately and efficiently.
In addition, a honing tool can help garages build their reputation and increase the costumer loyalty.
What are the advantages of having a cylinder honing tool?
There are several advantages to having a cylinder honing tool in any car garage, such as enabling mechanics to provide personalised services, as mechanics can adapt the polishing process to the specific requirements of each engine, in addition to boosting productivity.
What care and maintenance does a cylinder honing tool require?
To ensure cylinder hone tools work well and to extend their service life, it is essential to follow some basic care and maintenance, such as:
- Wiping your tool with a dry cloth to remove dirt. Avoiding using water or harsh chemicals;
- Lubricating parts, following the manufacturer’s lubrication instructions, and using the recommended lubricants;
- Checking the belt tension, taking into account the manufacturer’s instructions.
- Checking the tool’s alignment, as misalignment can cause excessive part wear and compromise polishing quality;
- Replacing damaged parts;
- Storing your tool in a clean, dry place, such as a tool cabinet.
