Offering the most powerful output in the LAPTRON series.
The super-high output LAPTRON 75R offers a maximum 48W. The featured rotary function produces high-frequency vibrations of 28,000 times per second. This supersonic lapping machine is most appropriate for lapping large-size molds.

Pursuing ultimate quality

Best ultrasonic die lapping machine
LAPTRON 75R is a high-grade lapping machine with a supersonic amplitude of 45 microns, a high power output of 48w max., and a 28,000c.p.s. frequency makes possible high-precision lapping with minimum force. The newly incorporated rotary mechanism further boosts operability, ensuring even novice user's of simple and high quality work performance.

High power output up to 48W max!!

High performance output patented around the world
The powerful supersonic oscillator which is the heart of the machine has been patented by Japan, the U.S.A., Germany, Switzerland and other developed countries.

Four-stage power output adjustment
High power output of 48 W maximum. Appropriate power selectable depending on operating conditions through four-stage power adjustment.

Varying frequency automatically controlled
Varying frequency depending on thickness and length of tips automatically traced. Vibration is controlled by the feedback frequency to maintain the optimum lapping condition.

Notable Work Examples
Lapping narrow slits (0.5 mm)
(Using SL tip)
Lapping deep and narrow slips (up to 180mm depth)
High quality finish easily achieved!!

Complex shapes and forms lapped with ease
Shapes difficult to lap using conventional manual work, such as rib, slit, deformed hole, concave bottom surface and precise angles at corners can be achieved with highly accurate lapping.

Work efficiency raised and high precision achieved

Work efficiency drastically raised because the work speed increases five to seven times manual work. Even beginners can perform mirror finish easily and speedily.

Wide lapping after oscillation discharge-proofing
Mirror finish with diamond paste
From precision molds to large sized molds!!

Deal with every type of mold
Every type of mold, such as plastic, die cast, press, as well as rubber and glass, can be lapped speedily.

Performance applicable to every material
Speedy and highly accurate lapping applicable to every material, from non-ferrous metal to cemented carbide. Particularly excellent in lapping after electric discharge machining.

Equipped with rotary mechanism
E Equipped with a high speed, high-torque motor
Employs a high torque motor (900g/cm) that can withhold heavy loads of work. What's more ,up to 15000 r.p.m. (DC 30V) is also ensured.
E High efficiency in curved surface work
Lapping work on round holes, radius surfaces and U-shaped grooves can be performed faster and more easily. Various tips available that can be attached and detached in one motion.
E Superior Safety Features
The mechanism is designed to automatically shutdown to maintain safe operation. It can easily be restarted by pressing the reset button.
