CNC grinder improves pump case quality

Suppliers, too, are beginning to feel the draught, and are being forced to change their ways of thinking and action taken.
How is it possible, though, to supply outstanding quality at a lower price? At Maegerle a cost-effective alternative has been developed for the process used to manufacture steering gear racks.
Traditionally this always involved a number of processes with broaching, milling, deburring and hardening stages followed by straightening.
A simpler and more economic way of achieving the same effect is to replace the broaching and milling with grinding.
The advantages are obvious: * The grinding wheel can be easily adapted using shaped dressing rollers.
* There is often no need for deburring as the rods are subjected to lower compressive forces.
* Induction hardening before grinding minimises deformation of the rods, greatly reducing the amount of straightening required.
* Short machine changeover times.
* Variable gear racks can be ground with up to three modules.
* Grinding at different angles of inclined axis with one and the same machine.
* No high investment costs for broaching or milling machines, no need to stock and sharpen expensive broaching tools.
The extremely and torsionally rigid deep grinding machines from Maegerle with their pre-stressed hydrostatic counterstay guides and powerful grinding spindle drives offer ideal, and highly economical, solutions to the problem faced when grinding steering gear racks.
Maegerle has two designs of machines to offer, depending on what their customers require: the MFP surface grinding and profile grinding machine or the MGC grinding center with its 180 rotary swivel table for loading and unloading during the grinding cycle.
Maegerle also offers both designs with fully automatic loading and discharge of the steering gear racks.
