Glebar Acquires Tridex Technology Ltd.
Tridex Technology Ltd. is a manufacturer of electrochemical grinding (ECG) technology.
Glebar chairman Adam Cook says, “Tridex further bolsters our core focus within the non-elective medical minimally invasive procedures market and expands our reach in aerospace and other industries.”
Tridex offers ECG technology as well as tube cutoff machines and other abrasive cutoff machines. ECG combines abrasive grinding with electrochemical machining to provide stress-free, low-force cutting with no burrs and no metallurgical damage such as recasting, heat-affected zone, burning or work hardening, the company says. ECG is widely used for tube cutoff of such parts as stainless-steel hypodermic needle tubing where deburring is not practical. ECG is also used for aerospace applications such as fragile honeycomb materials and turbine airfoils where the material is thin, fragile and heat-sensitive.
Two enabling technologies -- superabrasive wheels and high precision servo control -- come together to provide a contour grinding process that resembles an OD turning operation. For many medium volume OD grinding applications, this method may be a means to consolidate several manufacturing steps into a single setup.
Because of the high material removal rate creep-feed grinding can deliver in challenging materials, grinding might not be just the last step in the process—it might be the process.
Roughing and finishing on a single machine, using a single setup, has appeal for most shops. The advantages in time savings and accuracy are obvious. Eliminating the transport of workpieces between machines, as well as the setup for those secondary operations, is a boon for throughput. Critical features that need to maintain dimensional relationships can be much more reliably produced if machined complete in one clamping.
