Types of Resurface Cylinder Head Machines
Cylinder head resurfacing machines come in different types, each with its unique features and advantages. Choosing the right one depends on the specific needs of the workshop or garage, including the type of engines handled, the level of precision required, and the available budget.
In general, resurface cylinder head machines can be categorized into manual and automatic types. This distinction is primarily based on the level of human intervention and control required during the resurfacing process.
Manual Resurface CylinderHead Machines
Manual resurface cylinder head machines are simple, cost-effective solutions that rely on human precision and control. These machines typically consist of a base plate, a spindle, and a grinding stone. The user must manually position the grinding stone on the cylinder head, apply the correct amount of pressure, and monitor the resurfacing process to prevent over-grinding or under-grinding.
The advantages of manual resurface cylinder head machines include:
- Less expensive upfront cost compared to automatic machines
- No need for complex programming or electronics
- Greater flexibility for fine-tuning and adjustments
However, manual machines also have some limitations:
- Requiring skilled operators with good eye-hand coordination

Pre-Resurfacing Preparation: Resurface Cylinder Head Machine
Before resurfacing a cylinder head, it’s essential to prepare it properly to ensure a smooth and accurate resurfacing process. This involves a series of steps, including cleaning and degreasing the head, inspecting for damage, and positioning it correctly.
Cleaning and Degreasing the Cylinder Head
Cleaning and degreasing the cylinder head is a crucial step in preparing it for resurfacing. This process involves removing dirt, grime, and old gasket material from the head’s surfaces. A thorough cleaning and degreasing will help ensure that the resurfacing process is accurate and that the head’s surfaces are free from contamination.
- Use a degreaser to remove grease, grime, and old gasket material from the cylinder head’s surfaces.
- Wipe down the head with a soft cloth to remove any remaining debris.
- Rinse the head with water to remove any remaining degreaser.
Inspecting and Assessing Cylinder Head Damage
Inspecting the cylinder head for damage is an essential step in preparing it for resurfacing. This involves checking the head’s surfaces for wear, damage, or cracks.
- Check the head’s surfaces for wear, damage, or cracks using a visual inspection or specialized tools.
- Use a micrometer to measure the head’s surface finish and identify any areas that require additional attention.
- Assess the head’s core shift and core shift pattern to determine if it’s a contributing factor to the head’s wear.
Positioning the Cylinder Head
Properly positioning the cylinder head is crucial to ensure accurate resurfacing. This involves setting the head on the resurfacing machine and adjusting its position to ensure that the resurfacing process is even and accurate.
- Place the cylinder head on the resurfacing machine and ensure that it’s securely fastened.
- Adjust the head’s position to ensure that the resurfacing process is even and accurate.
- Use a level to ensure that the head is properly aligned with the machine.
Resurfacing Techniques
Resurfacing a cylinder head is a delicate process that requires a combination of precision, patience, and the right techniques. The outcome of this process can have a significant impact on the engine’s performance, efficiency, and longevity. With the right techniques and tools, it’s possible to achieve a smooth, even surface that meets or exceeds OEM specifications.
Lap-Joint Resurfacing
Lap-joint resurfacing is a traditional technique that involves using a grinding stone or a lap joint wheel to remove material from the surface of the cylinder head. This method is effective for removing small imperfections and can produce good results, but it has some limitations.
The lap joint wheel is a metal wheel that is coated with a grinding stone or other abrasive material. The wheel is designed to be held against the surface of the cylinder head, and the grinding action removes material as the wheel is turned.
While lap-joint resurfacing can be effective, it does have some limitations. The process can be time-consuming and may require multiple passes to achieve the desired results. Additionally, the lap joint wheel can be prone to overheating, which can damage the cylinder head or other engine components.
Water-Jet Resurfacing
Water-jet resurfacing is a more modern technique that uses a high-pressure jet of water to remove material from the surface of the cylinder head. This method is faster and more efficient than lap-joint resurfacing and can produce very smooth results.
The water-jet resurfacing machine uses a high-pressure pump to create a jet of water that is directed at the surface of the cylinder head. The abrasive properties of the water and the high-pressure jet work together to remove material and smooth the surface.
Water-jet resurfacing has several advantages over lap-joint resurfacing. The process is faster and more efficient, and the results are often smoother and more even. Additionally, the water-jet resurfacing machine is easier to maintain and operate than the lap joint wheel.
Correct Pressure and Speed Settings
Achieving the correct pressure and speed settings is crucial for successful resurfacing. The pressure and speed of the resurfacing machine will depend on the specific machine being used and the type of material being removed.
In general, it’s best to start with low pressure and speed settings and gradually increase them as needed. This will help to prevent damage to the cylinder head or other engine components.
The pressure and speed settings should also be adjusted based on the specific material being removed. For example, if the material is particularly hard or abrasive, higher pressure and speed settings may be required to achieve the desired results.
Maintaining a Consistent Surface Finish
A consistent surface finish is critical for ensuring the proper sealing and operation of the cylinder head. To achieve a consistent surface finish, it’s essential to follow a few key guidelines.
First, the resurfacing machine should be regularly maintained and calibrated to ensure that it’s producing consistent results. This may involve adjusting the pressure and speed settings, cleaning the resurfacing wheel or water jet, and replacing worn or damaged components.
Second, the cylinder head should be thoroughly cleaned and degreased before resurfacing to remove any dirt, grime, or other substances that may interfere with the resurfacing process.
Finally, the resurfacing process should be carefully monitored to ensure that the surface finish is consistent and meets or exceeds OEM specifications. This may involve checking the surface finish with a micrometer or other measuring instrument and adjusting the pressure and speed settings as needed.
