Definitions
- the invention relates to the field of surface treatments. It relates more specifically to a method of satinizing a workpiece of a hard material, such as a ceramic, a cermet or a hard metal.
- Satin is a finishing operation of a surface, intended to give it a particular appearance between the glossy aspect and the matte appearance. It can be made on materials as diverse as glass, metal, plastic or even wood.
- the processes, aimed at obtaining a slight frosting of the surface, are of a chemical or mechanical nature, depending on the material to be treated.
- the glazing of the glass is, for example, generally carried out by etching in a bath based on hydrofluoric acid.
- metals such as steel, gold, brass, are usually satined by mechanical abrasion using a grinding wheel with grains of oxide or silicon carbide.
- hard material materials having a Vickers hardness greater than 1000 HV. These materials are generally chemically very stable, difficult to machine and resist chemical etching. In watchmaking, they are used for their mechanical properties, in particular because they scratch hard. They serve, for example, to make pieces such as boxes or bracelet links. Their surface condition is usually polished, which gives them a shiny appearance.
- the present invention provides this type of process.
- the method according to the invention makes it possible to obtain surfaces of hard material with a satin appearance.
- the installation represented in figure 1 typically comprises a handpiece holder 10 on which is fixed a piece 12 of hard material or having at least one outer layer of hard material, and an abrasive tool 14.
- the piece 12 is, for example, a watch strap link , of substantially parallelepipedal shape, the outer surface 16 is flat. Alternatively, the surface 16 could form a portion of torus, or sphere.
- the hard material is, for example, a ceramic material such as an aluminum oxide (Al2O3), a zirconium oxide (ZrO2), a carbide, a nitride, a cermet, a hard metal or any other Vickers hardness material. greater than 1000 HV.
- the piece 12 is previously polished by a method well known to those skilled in the art. In a variant of the process, it could be rough sintering or machining.
- the abrasive tool 14 is formed of an endless abrasive belt 18 and two guide rollers 20a and 20b, axes respectively AA and BB, at least one of which is rotated by a motor not shown.
- the strip 18 is mounted taut on the two guide rollers 20a and 20b distant by a distance greater than the sum of their radii, so as to be driven by the effect of friction.
- It consists of a substrate 22, such as a ribbon, and an active portion 23 integral with the substrate 22 and formed of abrasive particles agglomerated with a binder. According to the invention, it has particular structural characteristics which will be explained later.
- each particle of the strip 18 describes a path substantially in a plane perpendicular to the axes AA and BB.
- P1 the family of planes parallel to each other, in which the trajectories of the abrasive particles are inscribed.
- the abrasive belt 18 being driven by at least one of the guide rollers 20a and 20b, the surface 16 is brought into contact with it.
- the longitudinal axis of the part 12 is positioned perpendicularly to the planes P1. Depending on the desired saturation effect, the longitudinal axis of the part 12 could also be arranged parallel to the direction of movement of the particles, or form any angle with it. Regardless of the orientation of the part 12 with respect to the direction of movement of the particles, it must remain substantially constant during the satinizing operation.
- the part 12 is then slightly pressed against the abrasive belt 18 so as to engrave parallel micro-grooves, having a profile substantially V, about 2 microns depth.
- the piece 12 is held motionless, or moves, in a controlled manner, along a path in a plane P2 substantially parallel to the planes P1.
- This type of displacement of the part 12 makes it possible to form rectilinear grooves on the surface 16.
- the part 12 moves in a controlled manner, in a plane P3 that is not parallel to the planes P1, which makes it possible to generate parallel grooves more or less curved on the surface 16.
- the surface effect obtained is a satin effect with reflections according to the curves of the grooves.
- the relative displacement of the part 12 and the abrasive belt 18 must be such that the superposition of non-parallel micro-grooves on the surface 16 is avoided. Indeed, such a superposition destroys the desired saturation effect. It will be noted, in particular, that a displacement of the part 12 in the plane of the abrasive belt 18, no parallel to the trajectory of the particles, produces a non-satin appearance unattractive, due to the superposition of non-parallel grooves between them.
- a cam forming a gutter of radius of curvature R L or R I according to the orientation of the part 12 with respect to the strip 18, can be arranged behind the abrasive belt 18, so as to guide the latter and serve as a support in room 12.
- the abrasive belt 18 used for the process of satinizing a ceramic part according to the invention is schematically represented in FIG. figure 2a . It is formed of a flexible substrate 22 of fortified paper, canvas or cardboard, and an active portion 23 integral with the substrate and formed of abrasive particles 24 agglomerated with a binder.
- the abrasive particles 24 are calibrated diamond grains with a diameter of approximately 40 microns. Depending on the desired saturation effect, a grain size greater or less than 40 microns will be chosen.
- the active part 23 comprising the abrasive particles 24, does not cover the substrate 22 uniformly, but non-uniformly and nonrandomly.
- the active part 23 is distributed on the substrate 22 in aggregates forming patterns regularly distributed on its surface.
- this distribution is periodic, as is the case in figure 2a where the active part 23 forms circular pellets 26 arranged staggered on the substrate 22.
- the pellets 26 have a diameter of about 0.7 mm, and are 1 mm apart.
- Each consists of a large number of particles 24 agglomerated together with a metal binder, in this case nickel.
- the active part 23 is distributed on the substrate 22 in aggregates forming two horseshoes back to back. As before, these patterns are staggered on the substrate 22.
- Such abrasive belts are sold by the company 3M under the references 6400 J N40 F and 6480 J N40, and the company Meister Abrasives under the references Dia-Pellet N40 and Dia-Link N40.
- the use of these strips combined with the described procedure makes it possible to obtain, on pieces made of hard material, a particularly aesthetic satin effect.
- the method according to the invention does not not limit to the use of the bands described above. Any other abrasive strip having a spatial distribution of the active portion 23 in regular aggregates distributed on the surface of the substrate, is within the scope of the invention.
- FIG. figure 3 A photograph taken under a scanning electron microscope of a view of the surface 16 after the satinizing operation is given in FIG. figure 3 .
- the surface 16 is striated with micro-grooves substantially parallel to each other, having a substantially V profile, a depth of between 0.1 and 2 microns and a width of between 1 and 30 microns. The interaction of the visible light with the micro-grooves produces the satin aspect of the surface 16.
- FIG 4a schematically represents a first numerically controlled machining machine used for the automatic satin process according to the invention.
- the machining machine conventionally comprises a cylindrical carrier 30 of axis CC and an abrasive tool 32 with cylindrical symmetry, axis DD parallel to the axis CC.
- the part 12, with an outer surface 16, is fastened loosely to the workpiece holder 30, its longitudinal axis being parallel to the axis CC of the piece holder 30.
- the radius R pp of the workpiece carrier 30 is such that the radius of curvature transverse R I of the workpiece 12, is equal to the sum of the radius of the workpiece carrier 30 and the thickness e of the workpiece 12.
- the abrasive tool 32 is formed of a cylindrical support symmetrical aluminum, on which is attached an abrasive belt 18.
- the abrasive belt 18 is of the type of strip used for the manual process described above.
- the active part 23 is distributed on the substrate 22 in regularly distributed aggregates. These form patterns arranged periodically on the substrate 22.
- the abrasive tool 32 is a grinding wheel formed of a support 34 having cylindrical symmetry of aluminum, and an active portion 23 integral with the support and consisting of particles 24 taken in a binder.
- the distribution of the active part 23 on the support 22 is uniform.
- the binder is vitrified. It is formed of a ceramic compound based on SiO2, Al2O3, B2O3, Na2O, K2O, CaO and ZnO. This type of grinding wheel is known and marketed under the name vitreous bonded grinding wheel.
- the piece holder 30 and the abrasive tool 32 are separated by an initial distance greater than the sum of their two radii. They are rotated about their respective axes CC and DD by a motor not shown.
- the abrasive tool 32 mounted to move in translation along a path that is straight at first until it comes into contact with the workpiece 12, then circular so as to remain tangent to the workpiece 12.
- the distance of the tool 32 to the carrier 30 is slightly less than the thickness e of the part 12, in order to exert a slight pressure thereon.
- the distance d is set according to the desired saturation effect.
- the workpiece holder 30 and the tool 32 rotate about their respective axes CC and DD, and simultaneously, the abrasive tool 32 moves in translation on its trajectory.
- the particles and the part 12 describe trajectories forming in planes parallel to each other and perpendicular to the axes CC and DD.
- Note P1 the family of planes in which the trajectories of the particles and P2 the plane in which the trajectory of the part is inscribed.
- the satin process thus described is optimal for conditions of speed of rotation and advance of the tool 32, and speed of rotation of the workpiece carrier 30, determined.
- the axes CC and DD respectively of the workpiece holder 30 and of the tool 32 can be arranged perpendicularly or in a completely different orientation, without leaving the framework of the invention.
- the geometry of the workpiece carrier 30 and the tool 32 must be adapted to the chosen arrangement.
- the satin obtained then has a particular effect, due to the curvature of the grooves.
- the automatic glazing method according to the invention can also be applied to parts 12 whose outer surface 16 is flat.
- the part 12 is fixed to the cylindrical carrier 30, or to a flat workpiece. Whatever type of workpiece holder is used, it is immobile.
- the abrasive tool 32 is driven, as previously described, a rotational movement combined with a translational movement.
- the trajectory of the abrasive tool 32 is rectilinear.
- the workpiece holder 30 is arranged so that the surface 16 is placed on the trajectory of the tool 32, parallel to its speed of advance.
- the profile of the tool 32 is straight so as to conform to the surface 16.
- the optimum values of the rotational speed of the tool 32, and of the translation speed are possibly different from the values mentioned above.
- FIG 5a schematically showing a second installation for the method of glazing a ceramic according to the invention.
- the installation comprises a fixed holder 38 and an abrasive tool 32 as used for the automatic method described above.
- the abrasive tool 32 is rotatably mounted on a fixed frame 40, its axis EE being disposed horizontally.
- its axis EE is mounted mobile in translation along a path forming a circular arc of radius of curvature the transverse radius of curvature R I of the workpiece 12.
- the workpiece holder 38 is disposed in the vicinity of the frame 40 so that the surface 16 of the part 12 is tangent to the tool 32 over the entire trajectory thereof.
- the tool 32 sweeps its path in a movement back and forth, while turning on itself. It presses weakly on the part 12 so as to form rectilinear grooves parallel to each other on the entire surface 16. This then takes on a satin appearance.
- the workpiece holder 38 is formed of a disk 42 of axis FF comprising four supports 44a, 44b, 44c, 44d regularly distributed at its periphery, as shown, in a view from above, on the figure 5b .
- a part 12 is automatically loaded before the satinizing operation, and then discharged in the same way after this operation.
- the disk 42 performs a quarter turn, in order to present a new part to the abrasive tool 32.
- the second installation for a satin process according to the invention may, like the first one, be adapted for the satinization of flat surfaces.
- the profile of the abrasive tool 32 is straight, and the path followed by its axis is rectilinear.
- the automatic process of satinizing a piece of hard material can be performed using an abrasive tool 32 as used for the satinization of a metal part. It is possible, for example, to use a grinding wheel with diamond particles or silicon carbide, and a binder made of synthetic resin. However, the result obtained with such a grinding wheel is of a quality substantially lower than the quality obtained with the choice of abrasive tools according to the invention.
