Read the following questions and their answers in this section. They will teach you how grinding wheels are helpful in the real world.
Answer. Choosing the right wheel is crucial to ensuring grinding effectiveness. First, we need to select the appropriate grinding plate material. Also, we must consider the processing requirements of the workpiece material. Not only this, it’s important to pay attention to the hardness and bonding type of the grinding disc. Thus, it will help you to ensure its stable performance and shape during the grinding process.
Answer. Grinding disks wear out during use, making regular dressing and maintenance essential. Dressing involves using tools such as oilstones, diamond pens, or dressing rollers. Thus, it will help you to restore the performance and precision of this wheel. Additionally, it is necessary to clean the grinding plate surface at regular intervals. It will finally prevent damage from impurities and coolant residues. Proper storage of grinding discs to avoid moisture, heat, or impact is also necessary.
Answer. Common equipment failures include excessive spindle vibration and motor overheating. These failures may happen due to equipment aging, improper installation, or incorrect operation. To avoid these issues, inspect the equipment at regular intervals. Moreover, you also need to replace old parts. Apart from this, you must ensure the secure and proper installation of the grinding wheel. Also, you must follow standard operating procedures. During operation, control grinding parameters to avoid overloading.
Answer. Grinding disc breakage or bursting is a serious safety issue. Also, it is often related to improper grinding disc selection or insecure installation. To prevent such incidents, ensure that the grinding disc matches the equipment. Moreover, you should follow proper installation procedures. Next, check the grinding disk's condition during operation as well. After that, stop the machine and inspect it to see if you detect any abnormalities.
Answer. Substandard surface quality of workpieces can result from several factors. These factors include severe grinding wheel wear. Moreover, it also includes improper grinding parameter settings or incorrect coolant usage. To address this issue, consider the grinding plate condition and grinding process. Furthermore, you should choose the coolant with care. Moreover, you should make necessary adjustments and optimizations.
Answer. Rapid grinding disc wear increases production costs and affects grinding efficiency. To tackle this issue, optimize grinding parameters. Then choose more wear-resistant grinding plate materials. It also enhances the dressing and maintenance of grinding discs.
If you landed on this page, there’s a strong chance you are either participating in a test grind, or are getting ready to participate in a test grind with the team at UNITED GRINDING North America, or one of our competitors. If this is the case, and your test grind doesn’t meet your high standards, or your find yourself making concessions or getting delayed due to lack of preparation, contact us and we’ll get your test grind done right – the first time.

Whether you’re looking to test a tool grinding machine from WALTER, a cylindrical grinding machine from STUDER or a surface and profile grinding machine from BLOHM or MÄGERLE, our skilled US-based sales and engineering teams will work with you to help pinpoint the correct machine and define the process required to deliver the parts you need.
Our US-based Application Engineering Team at UNITED GRINDING North America has centuries of combined experience, and we tapped into that experience to bring you this cheat-sheet to help you make sure your next test grind earns a passing grade.
These are the elements that go into a successful test grind.
For best results, make sure you have an open line of communication between yourself and the Application Engineers conducting the test grind. They’re briefed thoroughly on the project, but questions always come up once they dive in.
Once lines of communication are established, we move onto the goal of the test grind. This is simply the key condition that needs to be met, and it can vary. Can the machine grind the part in the cycle time quoted, within the specified tolerances, and hold repeatability?
If steps 1 and 2 are done well, the test grind usually runs pretty smoothly. The correct parts are on hand to properly test, the objective is clear and it’s easy to communicate with each other about anything that comes up.
Our Application Engineers gather all the info that they can during the test grind, with a crucial factor being the accurate measurement of the parts. At UNITED GRINDING North America, we have an inspection lab with millions of dollars worth of measuring equipment in a room that’s specifically climate controlled for gathering precise measurements. In the off-circumstance where we don’t have the right piece of equipment to gather the required measurements, we’ll ship the part to a specialist who is able to gather these measurements for final confirmation.
