DedTru® Centerless Grinding Units are designed for use with your surface grinder to increase your machine’s capability for throughfeed, infeed and second operation plunge work for tool room lot sizes at a high level of precision at a lower investment cost. DedTru® Precision Centerless Grinding Units are designed to be used in high volume production grinding or job shop applications and produce one-of-a-kind prototype parts in either small or large quantities. Operators do not need specialized skills to operate this equipment.
The DedTru® Grinding Unit consists of a rugged cast base that supports the precision regulating roll, the work blade, guide, rest plate for throughfeed work and pressure roll for plunge work. A patented spindle design supports the regulating roll which is driven by a variable speed DC drive.The resulting spindle design locates the regulating roll while rotating it with precise accuracy. It forms the foundation for the DedTru® System’s precision in roundness, straightness and concentricity.
The Model C Fixture is used for throughfeed, infeed and secondary operations and has a 4” wide regulating wheel.
The Model C6 Fixture is built to handle longer parts and is used for throughfeed, infeed and secondary operations equipped with a 6” wide regulating roll.
Model PGF Fixture is used for infeed and secondary operations of parts which have multiple diameters, gears, splines, etc. that require a relieved regulating roll, blade, etc. The Model PGF allows the operator easier access to the end of the part for ID grinding applications.
Model IGF Fixture is designed for applications that require grinding the ID of parts closely concentric to the OD. Since concentricity tolerance of 1-3 microns have always been difficult to maintain, Unison offers users a simple solution.
