Polishing and lapping machines and accessories Polishing and lapping machines joke EL Table-top machines Polishing and lapping machines joke EL Our Series EL polishing and lapping machines have been a byword for quality and reliability in professional use for many years. Both bench-top units EL 300 and EL 380 were developed especially for machining small workpieces and individual parts in small series production. For example, these units have been successfully used in laboratories and research institutions for many years. The EL 300 machines can be fitted with an application arm or a pendulum arm. A pneumatic application fixture and a bottom cabinet are available as accessories for the EL 380 machine. The large production machines EL 600 and EL 700 were designed for series production. These machines already offer stepless speed control as standard. In addition for example, pneumatic application fixtures and other components allow you to make adjustments to exactly suit the individual application. Optional pendulum arm system: Pendulum arm with com- Processing of concave Processing of dies i joke EL - also available for special cases! The series EL machines can also be modified for special applications, for processing of concave or convex surfaces for instance.

7 9. Polishing and lapping technology // 9.2. Polishing and lapping 9 Polishing and lapping Basics High gloss with exact accuracy of form Polishing and lapping is used when there are very exacting demands placed on surfaces with regard to peak-to-valley height and flatness, with a high gloss finish being required at the same time. These results are achieved in a single work cycle with polishing and lapping. Most preliminary and subsequent work steps are no longer required, and the entire working process becomes noticeably more rational. The results can be examined immediately thanks to the reflective surface. Our polishing and lapping system consists of three components: Schematic representation of the polishing and lapping process Polishing and lapping disk Dosing and spray unit Bio-diamond emulsions LAM PLAN NEOLAP The polishing and lapping system can be used successfully on almost all materials. This involves using the polishing and lapping disks in conjunction with the Bio-diamond emulsions LAM PLAN NEOLAP. The dosing and spray unit carries the lapping medium at precisely defined intervals to the lapping disk in the correct consistency and in the optimum quantity. This optimum dosing reduces consumption costs to a minimum. Worn polishing and lapping disks can be re-lined by us at any time. Knee implant The diamond suspension can also be custom adapted on request. Simply tell us your special needs and we will make the right product for you at short notice and for a reasonable price.

Bi-Composite The new LAM PLAN M.M. Bi-Composite polishing and lapping disc consist of two different materials in a resin bond. Water-soluble and oil-soluble diamond fluids are used as lapping media. The diamond grit is subjected to a constant change in speed by the polishing and lapping disk segments of different hardness. This results in high stock removal and a polished surfaced in only one single processing stage! In plain language this means: you process your workpieces using these polishing and lapping disks taking markedly less time and in fewer processing stages. This is not the only advantage. The flatness of the lapping and polishing disk is also distinctly improved thanks to the dualcomponent technology and is guaranteed for considerably longer. All disks can also be re-lined at our works. Polishing and lapping disks LAM PLAN M.M.

Polishing and lapping Ceramic dressing rings with SPYLAP control system Ceramic dressing rings with SPYLAP control system The patented SPYLAP control system allows highly simple control over the temperature of the lapping disk (and the resulting flatness) during dressing. Each ceramic dressing ring is equipped with SPYLAP elements which change in colour from black to red in response to temperature increase during processing. Changes can therefore be detected at an early stage and the process parameters such as press, diamond fluid, etc. can be adapted in order to reduce the temperature again, thereby ensuring preservation of lapping disk flatness.

The brand new NEOLAP series from LAM PLAN is the new reference when it comes to performance, efficiency and userfriendliness. The products are biodegradable and VOC-free and can therefore be used without harm to humans and/or the environment. The emulsions achieve first-rate results on almost any material. They can also be used under conditions with very high contact pressure without any risk of running and the lubricant film tearing. The products are available in oil-soluble (series 100) and water-soluble (series 300) versions. The likewise water-soluble series 400 contains polycrystalline diamonds. These have a greater specific surface owing to their structure (multiple cutting) and provide high stock removal rates. This allows shorter processing times with simultaneous freedom from scratches!

17 9. Polishing and lapping technology // 9.3. Lapping 9 Lapping Basics Systematic Lapping is a metalworking process for improving the dimensions, shape and roughness of spherical or flat workpiece surfaces. Loose grit is used for lapping. Here, the lapping process itself involves metalworking with loose grit, which is distributed in a liquid or compound. This involves pressing the individual grit tips into the surface. The material is carried off in all directions, which produces the matt surfaces that are typical of lapping. Schematic representation of the lapping process The lapping process primarily enables two requirements to be fulfilled on the workpiece: High to very high surface qualities Extremely high accuracies of form Optimum adaptation of the three basic components is a prerequisite for achieving these requirements: The workpiece being worked Abrasive in the carrier liquid Lapping disk as the shaping element Sliding annular seal Magnetic winding Microphone diaphragm Type wheel Sliding seal Gas seal 17

Measuring and testing 9 Interference testing units LAM PLAN 18 W joke 35 W Interference testing units Reflective surfaces are required for measuring the surface quality obtained. Lapped, matt surfaces are therefore polished on the polishing table in order to carry out the test. The flatness can be reliably tested using optical plane face glasses. Our plane face glasses are made of glass ceramics. This material maintains its flatness even when temperatures fluctuate greatly, and it is very scratch-resistant. Plane face glasses are used in conjunction with an interference testing unit. The monochromatic light produced by a sodium vapour lamp has a wavelength of exactly mm (0.6 µm). Since only half the wavelength is used for the measurement, the measuring accuracy is 0.3 μm.
