smoothed particle hydrodynamics simulation and experimental analysis of sic ceramic grinding mechanism - sciencedirect

Crack induced surface/subsurface damage in SiC ceramic grinding limits the industrial application. A single-grain scratching simulation based on the smoothed particle hydrodynamics (SPH) has been used to analyze the SiC grinding mechanism, including the material removal process, scratching speed effect on crack propagation, ground surface roughness, and scratching force. The simulation results showed that the material removal process went through the pure ductile mode, brittle assisted ductile mode, and brittle mode with the increase of the depth of cut. The critical depth of cut for ductile-brittle transition was about 0.35m based on the change of ground surface crack condition, surface roughness, and maximum scratching force. Increasing the scratching speed promoted the transformation of deep and narrow longitudinal crack in the subsurface into the shallow and wide transverse crack on the surface, which improved the surface quality. The SPH simulation results were indirectly validated by the cylindrical grinding experiments in terms of the critical single grain depth of cut for ductile-brittle transition, and the trend of ground surface roughness and grinding forces.

ceramic - grinding in seconds: dvs now

Where technical development constantly finds new, innovative solutions, traditional materials such as plastic or metal are increasingly reaching their limits. For this reason, ceramic workpieces are increasingly being used in modern brakes and clutches in automotive technology, but also in future-oriented industries such as e-mobility, aerospace, medical technology, microelectronics, semiconductor technology and many more. This also creates new, demanding challenges for their processing.

Modern technical ceramics are produced in a sintering process. The advantage of this process is that the specific preparation of the ceramic starting material allows the workpieces to be manufactured precisely according to the desired technical properties. The disadvantage: after sintering, the workpieces can only be formed mechanically by machining. A special task for modern grinding processes.

The pioneers and namesakes of the double face side grinding process also offer convincing solutions in this demanding field: DISKUS WERKESchleiftechnikGmbH supplies a variety of sizes and techniques for grinding ceramic workpieces with diamond grinding tools.

Depending on the geometric dimensions, required dimensional tolerance, surface quality and cycle time, DISKUS WERKE can offer suitable machines from the DISKUS double face grinding machine series "DDS ... XR": A total of four different sizes and five different grinding processes are available.

Double-sided surface grinding offersparticular advantages. Since the workpieces are not clamped in the workpiece holders (transport wheels or masks) during the grinding process, the often thin and filigree workpieces are not subjected to any additional mechanical clamping forces.

In continuous grinding, ceramic workpieces from 0.8 to approx. 30 mm thickness and, depending on the size of the grinding machine used, up to 180 mm diameter can be processed. The maximum stock removal per grinding cycle is 0.2 ... 0.3 mm. Dimensional tolerances of up to 0.002 mm can be achieved. This process is suitable for large quantities.

In KDE grinding, the workpieces are moved loosely from the input point through the grinding chamber in a limited number of pockets from a round transport disc to the output point. During machining, the workpieces are located unclamped between the end faces of the grinding tools, pass through the grinding passes in succession and are ground down to the target dimension. When it approaches the finished dimension, the upper measuring probe of the disk-based process control computer IONIC 18 is activated and the workpieces are ejected from the machine when the finished dimension is reached by opening the output plate of the table.

Ofparticular importancefor the double surface grinding of ceramic workpieces is the specification of the diamond grinding tools required for the special recipe of the ceramic material as well as a controlled removal of chips and abrasive abrasion. This is where the interdisciplinary know-how within the DVS TECHNOLOGY GRUOP once againprovesits worth: In this case, DISKUS uses the expertise of the DVS abrasives manufacturer NAXOS-DISKUSSchleifmittelwerkeGmbHButzbach. Together, grinding tools have been developed in which the chip spaces between the abrasive grains can absorb the machined material volume of a workpiece and the resulting abrasion of the grinding tools and transport it out of the contact zone. As soon as the workpiece no longer covers the chip space, the chip spaces between the abrasive grains are cleaned again.

Thus, this process enables targeted, plane-parallel grinding of even very thin and sensitive workpieces within very narrow toleranceswith regard tothickness, flatness, parallelism and surface finish. With this grinding process hourly outputs of up to 5,000 pieces can be achieved. A further advantage of the KDE process is that workpieces with largeoversizescan be machined while the machine is running. For these workpieces, the grinding machine can also be equipped with an automatically following hold-down plate. This ensures that the workpieces are also guided safely outside the grinding area.Thusthe KDE process also represents an alternative to fine grinding with lapping kinematics.

The DISKUS product portfolio offers a double surface side grinding machine of the type DDS 750 XRE in a special version with a large table for simultaneous machining of both sides of flat surfaces, for example on large ceramic shaped parts with a diameter of up to 425 mm and a workpiece height of up to 80 mm. This grinding machine with vertical arrangement of the motor grinding spindles efficiently and precisely brings the workpieces with any desired oversize to the desired final dimension during machine operation thanks to special planetary kinematics in plunge grinding with controlled rotation of the workpieces.

Technical ceramic materials have become indispensable in many forward-looking industries - solutions from DISKUS WERKE and DVS TECHNOLOGY GROUP ensure that ultra-modern workpieces can be machined precisely.
