Usually, flat grinding serves the purpose of creating completely flat surfaces of work pieces. There are several process variations for flat grinding. Usually peripheral wheels, cup wheels and grinding segments are used. Notches and profiles are usually created by peripheral wheels. Here most commonly pendular as well as deep grinding with special open-pored grinding wheels are used.
Cup grinding wheels are universally used and common for finishing of small surfaces.
Grinding segments are an alternative to cup grinding wheels or peripheral grinding wheels when those cannot be used due to the limited diameter. But also for small diameters they are used due to their cool grinding. Compared to grinding cups and grinding wheels, their advantage is above all the high removal rate.
CARBORUNDUM produces grinding segments in ceramic bond and artificial resin bond. They are available in many shapes and variations.
Circular Grinding
Circular grinding is the most common grinding technique to produce precise cylindrical outlines and high surface qualities. This technique is divided according to the work piece bearing and the main feed direction, e.g. longitudinal grinding, cross grinding and infeed grinding. Generally it is distinguished between external and internal circular grinding as well as variations of infeed grinding, grinding between centers and as a special process variation
centerless grinding which takes a special position owed to the special field of use. Because of the good economic efficiency and the optimal automation possibilities, the main field of use of centerless grinding is in large batch production.
CARBORUNDUM produces grinding wheels for circular grinding in ceramic and artificial resin bond as well as in rubber bond.
Roll Grinding
Roll grinding is mainly used in the steel industry, aluminium foil and paper industry, depending on the particular machine manufacturer and the drive power of the respective machines. Generally, grinding wheel 600 – 1,500 mm diameter and 65 – 150 mm width are used.
Typical for roll grinding are partly extremely high chipping rates during rough grinding of rollers, especially in steel industry.
In the aluminium industry as well as in the paper industry great demands are made on the quality of the rollers with respect to true rotation, parallelism and surface quality. Typical defects like commas, feed marks and chatter marks are to be excluded.
Here CARBORUNDUM offers the mainly used grinding wheels in artificial resin bond as well as grinding wheels in ceramic bond.
