Our hit model has an added rotary function.
The rotary function added to the LAPTRON 55 has been used worldwide. The LAPTRON 55R is a dual role supersonic lapping machine.

LAPTRON 55R equipped with a rotary mechanism

The rotary mechanism, effective on curved surface work, adds to the basic functions of LAPTRON 55.
Efficiency further increased. Further high quality and extreme precision realized. Able to deal with any complicated shape in a wide range of work.

The exclusive hand-piece makes lapping work easy even on curved surfaces! !

Employs a high-output, high-torque motor.
The high-output, high-torque motor ensures speeds up to a maximum 15,000 rpm and a torque of 900g/cm.
The model displays its greatest force when lapping round holes, rounded surfaces, and U-grooves.
A range of chips can be used with the LAPTRON 55R, and an exclusive holder is provided on the main unit.

Four-stage power output adjustment

High power output of 45 W maximum. Appropriate power selectable depending on operating conditions through four-stage power adjustment.

A new circuit precisely controls chip status.
Frequencies that change according to the length and the thickness of chips are automatically traced and monitored.
Data are instantaneously fed back to control vibrations, thus maintaining optimum processing status.
In addition, the control circuit also prevents abnormal heating of chips, thus eliminating damage to ceramic chips.

Notable Work Examples
Lapping narrow slits (0.5 mm) (Using SL tip)
Lapping with ceramic stone
Just one single unit for any type of lapping work!!

Handling any shape
In addition to conventional chips for lapping, rotary chips can also be used.
As a result, round holes, rounded surfaces, and U-grooves can be lapped accurately. Furthermore, the lapping of ribs, slits, irregular shaped holes, surface grinding of dented areas, and angle work on corners can be achieved easily.

Simultaneously achieving workability and high precision

he LAPTRON 55R offers high efficiency requiring one-fifth to one-tenth the time to accomplish the work manually.
Even a beginner can quickly achieve high-precision processing from rough lapping to mirror finish.

Lapping deep ditches (Using diamond electrode tip)
Mirror finish with diamond paste

Easy finishing of both precision molds and large-size molds! !

Accepts any type of mold
The LAPTRON 55R model can handle any type of mold, including plastic molds, die- cast molds, press dies, and molds for rubber and glass, ensuring quick lapping.

No worry about mold materials
Lap both nonferrous metal and hard metals, ensuring high precision lapping whatever the mold material.
Excellent performance is ensured during lapping after electric-discharge machining.

Equipped with rotary mechanism
E Equipped with a high speed, high-torque motor
LAPTRON 55R is equipped with a rotary mechanism driven by a high-torque(900g/cm) , high-power motor with a maximum speed of 15000 r.p.m. (DC 30V).
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.
