High pressure cooling of grinding wheels in machine tools
This application note provides an overview of the successful use of a hydraulically flexed diaphragm pump to cool machine tools.
The cooling of machine tools is vital to ensure that heat is dissipated adequately and hence the product being worked on is not damaged by the process.
A leading UK manufacturer of stainless steel small hand tools had previously used a high flow, low pressure centrifugal pump for coolant transfer on grinding processes; however this pump was unable to wet the grinding wheels sufficiently. This often resulted in clogging and over-heating, and hence reduced production.
Michael Smith Engineers supplied the client with a high pressure, low flow triplex diaphragm pumps as an alternative. The high pressure capability of these pumps ensures that the grinding wheels do not clog, and the client has since reported a 15% increase in production as they have been able to increase the grinding speed. Downtime has also been reduced as the grinding wheels require less frequent cleaning.
|Stainless steel pump head||Corrosion resistant||Long pump life|
|Triplex diaphragm design||Virtually pulse-less flow||Smooth, consistent spraying|
|Hermatically sealed diaphragms||Zero leakage of coolant||No spillages, no wastage|
|Hydraulically balanced diaphragms||Stress on the diaphragms is significantly reduced||Reduced down-time|
|High pressure capability||Better removeal of build up from the grinding wheel||Reduced down-time|
|Grinding wheels do not clog||Increased production speed|
|Close coupled||Compact design||More plant workspace|
