Cnc sharpening machine
Most companies which business consists mainly of machining and manufacturing need of sharpening machines
and CNC grinding machines
, which offer an additional performance and reliability.
The grinding machine
is indeed of capital importance for plants required to produce precision workpieces, especially in the mechanical, automotive and aeronautics industries, and must be able to rely on tools that maintain a good quality machining as long as possible.
The main role of the grinding machine and its CNC variety, the CNC sharpening machine
, is to guarantee gear cutting and grinding of carbide or polycrystalline cutting tools. Put differently, the grinding machine permits the sharpening of the blades and the tools which are subjected to wear down because of their repeated contact with the materials - mainly metals - which constitute the workpieces to be machined.
The sharpening of carbide tools is based on abrasion and grinding techniques. The grinding wheels used in the sharpening are made of diamond powder, silicon carbonate or emery paste. They are put into contact with the metal at a very high speed removing material to "sharpen" it. The system is generally cooled by a water bath or by ventilation.
Depending on the models, the brands and the applications for which they are intended, sharpening machines
and CNC sharpening machines
are equipped with a variable number of axes; it may be equipped with two to nine axes.
For polycrystalline tools, the machines are equipped with an "electroerosion" function improving their productivity.
These devices are used, for example, sharpening saw blades. In this case, they are characterized by the outer diameter of the circular saw blade. These machines can also be used for grinding spindles, drills and mills.
Whatever the tool to grind is, the objective is to maintain its sharpness, its cutting ability, and therefore its efficiency as much as possible.
Enterprises productivity depends, partly, on the performance of their grinding machines and CNC grinding machines.
ANCA, EWAG, Schneeberger, Vollmer
WerkeMaschinenfabrikGmbH, Wood-Mizer, and Monnier & Zahner AG are among the leading designers of CNC grinding machines. On the second-hand market
, these machines are rigorously inspected and maintained in order to provide optimum grinding quality of machining tools.
