The small and stable power for micro palling and the high power required for lapping of large molds can be handled with one ALL III machine.

Long-term Continuous Operation” and a “Wider Power Zone.”

Product_Supersonic Lapping Machine_LAPTRON ALLⅢ

Long-term continuous operation without interruption.

The newly developed transducer and the control circuit where heat generation is suppressed to the limit enabled stable lapping work without interruption triggered by the safety device even after many hours of use.

It ensured for large-size molds and micro-lapping

the high power of 50 μm maximum down to the extremely fine vibrations of 1μm minimum are achieved.  The wider power zone enabled wide-range lapping of large molds and precision lapping of micro-machined molds.

It ensures that the user will hardly feel fatigue even after many hours of use.

The newly developed φ25 ㎜ small diameter hand tool features the use of aluminum with excellent heat dissipation characteristics and a rib design that works as heat dissipation fins and a finger grip.

A wide variety of tips are available; for example, a ceramic stone, a metal bond-diamond tip, an electroplated diamond tip, softwood tip, and standard tips to support various types of lapping including from removal of unevenness generated at processing and hardened layer to finishing lapping of ebony and all kinds of metals, such as brass. In addition, a 120-degree chuck is also available to conveniently lap complicated portions. There are also many kinds of rubber grindstones waiting for you.

Research on Supersonic Polishing

The transducer is subject to flexural oscillations and it expands and contracts in the longitudinal direction.  Execution of the transducer movement simulation and analysis of behaviors of the lapping tip end reveal that flexural oscillation overlaps the vibration amplitude of vertical oscillation, thereby causing the tip end to make an elliptical motion. Supersonic lapping becomes possible by performing such motions 18,000 to 26,000 times a second.

Analysis of Heat Generation Mechanism

Even when a product boasts high power, improvement in efficiency would not be achieved after repeated operational shutdowns caused by heat generation. To solve this problem, we pursued complete heat dissipation. Starting from optimization of the oscillator, we repeated trial and error over reexaminations and redevelopment of the control circuit, in addition to the selection and shape of materials for the chassis. Furthermore, thermographic analysis was applied to the prototype machines, and infinite processes of trial and error were repeated before we could conquer the problems without compromise.

Simultaneous Achievement of Stable Micro-Vibration and High Output

To realize a lapping machine which is capable of performing a series of operations from handling of mirror finish that needs stable micro-vibration under the loaded condition, up to erasure of flaws by using a machine tool where the speed and the high output are demanded by only one machine. For such apparently contradictory needs, we succeeded in setting up the position, shape, and size of the transducer after repeating various analyses and simulations, as well as processes of trial and error. The result is the development of the ideal transducer that is persistent to micro-vibrations and is capable of seamlessly dealing with a wide range of outputs up to high output.
