While we're having an interesting year, we thought we'd lighten things up a bit with a good old fashioned contest.
The Rules are simple!
- Must be photos using a Goodson koozie
- Photos will be judged on creativity and location
- No entry limit, send as many as you want!
- Deadline is June 21st at 11:59 pm
- Email photos to Goodson or post them in the comments section below.
Winner will receive a Goodson 75th Anniversary t-shirt, Goodson 75th Anniversary koozie and a Goodson racing hat!
Get those creative juices flowing and think of some awesome photos to capture once life gets back to normal! We can't wait to see them! Good luck!

As you know the flywheel grinder in your shop should be one of the most profitable machines in your business. With basic skills, training and the following information, just about anyone in the shop can grind a flywheel properly. The set up is simple and the job itself is very fast. In most cases you should be able to average about $100 per hour if you can keep the work coming in from your customers.
Here’s a quick overview of how to set up and use your flywheel grinder.
CBN Flywheel Grinding Wheels are a relatively new addition to the flywheel grinding arsenal. Since they are so new, there’s been some confusion about them that we’d like to clear up.
- CBN Flywheel Grinding Wheels are constructed as an aluminum or graphite substrate and form into a cup (type 11) with CBN (cubic boron nitride) material cemented to the flair.
- CBN Flywheel Grinding Wheels are recommended only for use on ferrous materials; specifically cast iron.
- Because there is no real porosity in the CBN Flywheel Grinding Wheel, use them with large amounts of clean flywheel grinding coolant pointed at the wheel contact area. This will lubricate, cool and carry away swarf created during grinding. We also suggest you use a filter sock on the coolant returning to the sump to help minimize swarf returning to the wheel through the sump. Never crowd the machine or use a power feed while grinding as this will build heat and chunk the wheel.
- CBN Flywheel Grinding Wheels are great for finishing 90 degree steps in flywheels.
- CBN wheels create less dust
- CBN wheels can last 8 times longer compared to vitrified wheels on average.
- CBN wheels will last longer and create less heat when used with fresh, clean coolant.
As always, if you have questions about the Goodson CBN Flywheel Grinding Wheels, Flywheel Grinding in general or any other Goodson product, feel free to contact the Goodson Tech Services Department at 1-800-533-8010 or shoot us an email.
CBN and PCD, the Newer Alternatives
By Dave Monyhan
There has been quite a rush to CBN (Cubic Boron Nitride) in cutting iron in the last ten years. Some machines are just wet grinders converted to use a CBN bit. Others have been designed to be a CBN cutting machine. Set up is critical when using CBN. The aggressive cutting action it delivers is directly related to how true the set up is and how conscientious the operator is.
CBN, an ultra-hard cutting material consisting of polycrystalline cubic boron nitride with a metallic or ceramic binder is primarily used to machine hardened ferrous material. It’s available either as a tip brazed to a carbide insert carrier or as a solid insert.
CBN has its limitations. It likes to cut large amounts of material with out interruption. Guess what? The average cylinder head or block has many holes that interrupt the cutting action of the tool bit. With that in mind it’s even more critical to have correct speeds and feeds on your surfacer to adjust for machining cylinder heads and blocks. CBN must be driven by rigid machine tools with secure holding fixtures. As I stated earlier, some CBN machines are simply converted wet grinders, and others are designed as CBN machine. But not all CBN tips are the same. The purity of CBN content separates price from quality. I recommend the titanium coated CBN tips, due to the witness mark left on the tip after you have surfaced a workpiece. Plus the titanium coating delivers longer life. These tips can be rotated about every 2-3 degrees so you can get the maximum life out of the tip. Plus if you’re using a solid CBN tip, after one side is worn out you simply flip it over and use it again. It’s essential that when you rotate the tip, that the holder is clean and the holding finger is sound. There’s nothing worse than having your machine throw a $250 tool bit somewhere in the shop, because chances are you are not going to find it. CBN can also be sharpened. If the tip isn’t fractured, it can be lapped back to spec, extending the life of the tip.
PCD (Polycrystalline Diamond) is an ultra-hard tool material (substrate) consisting of a synthetic polycrystalline diamond tip brazed to a carbide insert carrier. Primarily used to machine non-ferrous materials at high speeds, PCD has been developed specifically to machine aluminum. CBN only smears the aluminum when removing metal without producing the necessary finish today’s aluminum heads require. To extend the life of your tooling, use adequate lubrication.
