Abstract
A process for the low-wear micromachining of workpieces made from metal or metal alloys, in particular steel, in which a workpiece (1) is micromachined using at least one machining apparatus (5) that has a diamond tool (6), in particular an ultraprecision turning, milling or grinding machine, and prior to the micromachining the workpiece (1), in a first step, is subjected to a thermochemical surface zone treatment, and that in a second step the thermochemically treated surface zone (2) of the workpiece (1) is machined using the machining apparatus (5).
Claims10
A process for the low-wear micromachining of workpieces made from metallic materials or metal alloys in which a workpiece (1) is micromachined using at least one machining apparatus (5) that has a diamond tool (6), comprising the steps of:
- a) prior to the machining, subjecting a surface region of the workpiece (1) to a thermochemical surface layer treatment so as to create a thermochemically treated surface zone (2) within the surface region of the workpiece (1) by introducing a selected element or combination of elements to the surface region of the workpiece (1) and by allowing the selected element or combination of elements to penetrate into the surface region of the workpiece (1) so as to create the thermochemically treated surface zone, and
- b) machining the thermochemically treated surface zone (2) of the workpiece (1) using the machining apparatus (5).
