FAQ's > Finishing and Grinding Machines
Question: How will a belt or disk grinder help me work with my materials?
Answer: A well made belt grinder will quickly and smoothly remove stock, shape, contour, and modify the finish of many material types.
Question: What abrasive speeds are best for which materials?
Answer: In general abrasive speeds from 4000 to 8000 surface feet per minute are recommended for mild steels and aluminum. Abrasive speeds from 3000 to 6000 surface feet per minute work well with stainless steels and cast irons. Exotic materials such as titanium generally prefer speeds below 2000 SFPM. Plastics and other polymers usually prefer speeds below 2000 SFPM. Woods and similar fibrous materials are often best ground below 6000 SFPM. Grinding speeds are determined by the material to be ground, the finish desired, and the abrasive used.
Question: What abrasive types are available for use on Burr King grinders?
Answer: Every major abrasive manufacturer in the world manufactures abrasives that are suitable for Burr King grinders. Abrasive materials include diamond, aluminum oxide, silicon carbide, and other mixes and compounds often referred to under proprietary trade names.
Question: Do Burr King grinders use standard commonly available belts and discs?
Answer: Yes, all Burr King grinders use belts and/or disks that are readily available around the world.
Question: What is a well-made belt or disk grinder?
Answer: A well made belt or disk grinder incorporates the following:
1. Balanced, smooth running belt or disc tract for an ideal; fatigue reducing, abrasive to work piece interface.
2. Versatile modes of operation that include contact wheel, platen, work rest, and slack belt grinding and finishing.
3. Ample horsepower to drive the abrasive past the work piece.
4. Abrasive speed (surface feet per minute) designed for modern abrasives and a wide variety of materials.
5. Rugged design for better performance and long life.
Question: Can Burr King grinders be used under "wet" conditions?
Answer: Yes, however grinders used under "wet" conditions must be configured to meet NEMA 4 or 4X standards. These standards specify design requirements for electrical safety in wet use.
Question: When should I use a serrated contact wheel?
Answer: A serrated contact wheel is a wheel with groves place in the wheel face to speed material removal, extend abrasive life, and reduce temperature build-up. Use serrated wheels when you require rapid material removal and finish is of secondary importance.
Question: Are serrated contact wheels available on Burr King grinders
Answer: Yes, all Burr King grinders are available with smooth faced or serrated contact wheels.
Question: Do Burr King grinders conform to common safety requirements such as belt guarding and pinch point protection?
Answer: Yes, all Burr King machines are designed to comply with OSHA and other safety definitions.
Question: Are Burr King grinders available in international electric power configurations?
Answer: Yes, all Burr King products will operate, or may be adapted to most AC main voltage and frequencies. Please consult with our factory. All are available in popular 60 hertz power options.
Question: Can Burr King belt grinders be used in other ways than belt grinding?
Answer: Yes, most Burr King grinders are designed to accept buffing wheels, nylon wheels, and similar de-burring/polishing devices. Stone wheels and other similar hard wheels must never be used on a Burr King belt grinder.
Question: Can Burr King belt grinders reach into small cavities, radii, and other hard to reach places?
Answer: Yes, all Burr King belt grinders are designed to either do this type of grinding directly, or to accept adapters to gind/finish in this manner.
Question: Will Burr King grinders deliver finishes in the low RA, or micro region?
Answer: Yes, finishes from coarse to low RA, or low micron finishes are readily achieved by matching the machine, abrasive speed, and abrasive material to the material type to be ground.
Question: Can Burr King belt grinders be used for "on center" or "centerless" grinding?
Answer: Yes, most Burr King models can be adapted for either mode of grinding.
Question: How is grinding/polishing residue that is generated by the grinding machine dealt with?
Answer: All Burr King grinders are readily adapted to in-house dust collection systems. Burr King also supplies a comprehensive line of stand alone dust collection systems ideally suited for your finishing needs.
Question: Where can I get technical assistance in selecting the best grinding/polishing machine for my application?
