In the era of industry 4.0, there are many advancements are made in the field to increase the work efficiency of the plant and also improve the productivity rate of the industry. The various advanced machine is used for assembly purposes so the quality of the product will also increase significantly. Time-saving is one of the most important factors in all the manufacturing industries because with the efficient time-saving method there is improvement in all other standards of the manufacturing industries.
Metal is used as a raw material for various major manufacturing industries and the most important part of the automotive industries for building frames for various automobiles and metal is also used for various things other than in the industries. Metal is a major part of industrialization and is also used to make bridges, large iron frames, ships, boilers, and in construction also.
As the most common metal used for various large-scale production and construction is iron as it is the most abundant metal found in the earth's crust. Iron is also reactive and reacts with air and moisture to form rust. Rust can weaken the integrity of the structure and to prevent the iron from rusting proper care is also taken of the iron structure. Paint is applied to the structure to prevent its contact with the air & moisture. Rust can be removed from the iron structure as it forms on the iron surface and slowly made its way into the metal.
YOKOTA which is a respected Japanese brand has a wide range of air tools that are used to remove the rust and paints from the ships, iron frames, and boilers with excellent efficiency without any load on the operator.

YOKOTA SCALING HAMMER
Yokota scaling hammer is an air tool that runs on compressed air and is commercially used in industries for removing the rust and paints from ships, large-scale iron frames, bridges, and boilers. These applications are very large compared to a human manually working on them to remove the rust and paint.

Yokota Scaling hammer is an efficient ergonomic air tool that can remove paints and rust from metal. It can provide blows up to 8000 B.P.M and consume very small compressed air in comparison with other conventional tools used for the same purpose.


• YOKOTA SCALAR
Yokota scalar is another model for removing the rust and the paint from metal applications. It is different from the scaling hammer because the scaling hammer uses hammering action for chipping out the rust whereas the scalar uses friction to remove the rust & paint.

Yokota scalar uses accessories along with the tool to remove the rust and the paint. It is an ergonomic tool and can cover large-scale applications very efficiently. It rotates at a speed of around 3000RPM with small air consumption.

YOKOTA Pulse Tool Motor
YOKOTA is a respected brand all over the world for providing assembling solutions their pneumatic system wrenches are one of the best in their respective field. The YOKOTA system wrench comprises tools with torque ranging from 4Nm ~ 500Nm and pulse tool with torque ranging from 4Nm ~ 300Nm.
YOKOTA pulse tool can do tightening at a very high speed and without any reaction force due to its special pulse unit and its double chamber motor working simultaneously to provide a smooth experience to the worker and tightening result is very accurate with an accuracy rate of 6% in system wrenches.

Working of Pulse tool Motor
The pneumatic motor uses air to produce rotational motion to a shaft. The primary rotating part is a rotor with slots on its surface which is mounted on the main drive shaft. Each slot in the rotor is fitted with sliding rectangular blades. The vanes get extended to the housing walls by the cam action, or air pressure, depending on the different motor designs. Air is injected into the motor input which pushes the blades in the slots creating the rotational motion of the central shaft. Rotation speeds of the Pneumatic motor can differ between 100 and 25,000 rpm depending on various parameters which include air pressure at the motor inlet and the continuous pressure provided by the compressor. Pneumatic pulse tools are powered by air that is delivered by a compressor at a high pressure ranging from 3bar ~ 8bar. The air is sent to the tool through a regulator which is set at a certain level required by the tool. The air required by the tool should be free from moisture. Once the air enters the tool, it’s fed to a rotor chamber where the compressed air hits the blades due to which the rotor begins to rotate. The rotor can rotate in either direction only the intake direction of the air is changed.

YOKOTA uses a variety of motors for their tools: -

· In YEX models the motor used a cylindrical eccentric motor or the plate eccentric motor, which has a power output with the feature of lightweight and compact.
In TKA & YED models the motor used has a double chamber air motor, and the generated torque is increased by two times due to the use of multiple blades.
In the YLA series the motor is newly designed for higher efficiency. It requires no lubrication due to its self-lubricating blades and cylinder that last 2 times longer than the conventional ones.
YOKOTA has introduced their new generation Pneumatic and electric system wrenches in India Market through Microntech. Microntech offers the most elegant solution for the most critical applications on assembly lines.
