Understanding Head Resurfacing
What is Head Resurfacing?
Head resurfacing is the process of machining the surface of an engine head or block to restore its flatness and finish. Over time, surfaces can become warped due to heat, corrosion, or mechanical stress, which can lead to serious engine issues, including head gasket failure.
Importance of Surface Finish
A proper surface finish is critical for ensuring a good seal between the head and the engine block. Late model engines often require a mirror-like finish to accommodate modern MLS (Multi-Layer Steel) head gaskets, which demand tighter tolerances.
Types of Head Resurface Machines
Dedicated Resurfacer
Dedicated resurfacing machines are specifically designed for the task of surfacing cylinder heads and engine blocks. They typically feature robust construction and are equipped with CBN (Cubic Boron Nitride) or PCD (Polycrystalline Diamond) cutting tools, making them capable of achieving high-quality finishes quickly.
CNC Machining Centers
For shops that require versatility, CNC machining centers offer a multi-functional approach. These machines can perform a variety of tasks, including surfacing, boring, and drilling, all in one setup. This can significantly reduce setup time and improve accuracy, making it a smart choice for high-volume operations.
Manual Resurfacer
Manual resurfacing machines are often more affordable options for smaller shops or those just starting out. While they may require more operator skill and time, they still provide the capability to achieve good results when properly used.
Automatic Resurfacer
Automatic resurfacing machines are designed for high-volume applications. They automate the resurfacing process, ensuring consistent quality and reducing the need for manual intervention. This can be a game changer for busy shops that need to maximize efficiency without sacrificing quality.
Key Features to Consider
Power and Performance
When selecting a resurfacer, consider the horsepower and torque ratings. Machines like those from jamisonequipment.com often feature powerful motors that allow for efficient material removal and can handle both cast iron and aluminum surfaces effectively.
Fixturing Options
Proper fixturing is essential for accurate resurfacing. Machines should allow for quick and easy mounting of various head types. Look for machines that can accommodate a wide range of head and block sizes, such as those from www.rottlermfg.com.
Surface Finish Quality
The desired surface finish will dictate the type of cutting tools used. High-quality machines can achieve surface finishes as low as 10 RA, which is critical for modern engines. Make sure to assess the machine’s capabilities against your specific needs.
Maintenance and Support
Consider the availability of maintenance services and customer support from the manufacturer. Brands like theultimatetooling.com provide ongoing support and parts for their machines, ensuring longevity and reliability.

Choosing the Right Machine for Your Shop
Assess Your Needs
Before making a purchase, assess your shop’s specific needs. Consider the volume of work you anticipate, the variety of engine types you’ll be servicing, and your budget constraints.
New vs. Used Equipment
When deciding between new and used equipment, weigh the benefits of modern technology against potential savings. New machines typically come with warranties and support, while used machines can be more cost-effective but may lack reliability.
Brand Reputation
Opt for machines from reputable manufacturers like www.comecpn.com and tnsmachines.com to ensure you’re investing in quality equipment that will last.
