Cutting & Grinding Oils
Cutting & Grinding Oils

Cutting work is to make a shape that people want by
trimming unnecessary parts of material with hard knife
harder than the material, and grinding work is to finish the
surface of material, which is ground by abrasive particles in
a grinding wheel. Cutting and grinding oils are used to
prevent tools from damage, to preserve facilities, and to get
top-quality products by enabling appropriate cooling and
lubrication.
Features
Use of multi-functional materials based on the top
synthesizing technology enables to solve the existing
problems such as unstable emulsion, bubbling, short
lifetime, rust, etc. They are economical and efficient because
of long-term use without being affected by the hardness of
material or water. Furthermore, they are eco-friendly and
not harmful to humans due to the decay-free feature in spite
of no preservatives used.

Cleaning Oils
Cleaning Oils
After cutting, forming, rolling, etc. end, the following
processes are painting, coating and assembling. Cleaning
oils are used to remove used pollutants (process oils)
remaining in processed materials. They are classified into
solvent type and water-soluble alkali type according to the
amount and status of pollutants.
Features
Buhmwoo’s cleaning oils have excellent cleaning power
because of the use of special alcohol surfactant and
complex degreaser, minimize the amount of bubbles in
using a high-pressure washer, and prevent the
reattachment of oil, fine dust and ground powder, leading to
keep the cleanness of processed materials.

Anti-Rusting Oils
Anti-Rusting Oils
Anti-rusting oils are used for anti-rusting to prevent metals
from being contacted with moisture or acid. When applying
this oil, it forms a powerful adsorbing film on the metal
surface, which blocks water, air and current flow.
Features
With good anti-rust, degreasing, water displacement, and
anti-oil stain, Buhmwoo supplies diverse and environmental-
friendly products suitable for various work conditions of
customers.

Heat Treatment Oils
Heat Treatment Oils

In case of metals, their physical and chemical properties
may be changed by a heating and/or cooling method. Heat-
treatment is a thermal process of using such properties of
metals. To increase the strength of metals, it needs a heat-
treatment process through a cooling medium which is heat-
treatment oil.
Features
Buhmwoo supplies custom-made products for each
customer after reviewing the working conditions and the
required property, analyzing the metal structure and
process, and selecting and developing proper oils. Our
products are designed and manufactured to have long-term
stability in the cooling function and luminance and in the
resistance to heat and oxidation by combining advanced
base oils and functional additives.

※ In Korean Industrial Standards, heat treatment oils are classified by their use and its corresponding performance. In other overseas standards, similar
conditions are used to classify them.
1-2. Cooling Property of Heat Treatment Oils

Water-insoluble/soluble heat treatment oil has three cooling steps when cooling hot metal; vapor barrier, boiling, and
convection. The step is decided by various elements such as its viscosity, oil temperature, additive, concentration,
degradation, and field agitation condition.

Rolling Oils
Rolling Oils
Rolling is a process to reduce the thickness of a material by
passing between rolls. In this process, rolling oil enables to
work smoothly by controlling heat generation and wear
caused by friction and lubricating the metal and the rolls to
prevent plastic deformation on the strip.
Features
Buhmwoo’s rolling oils implement both eco-friendly work
environment and improved steel quality by minimizing the
pollutants on the surface of the steel and facilities using
properties of super clean. In addition, with the design for the
products optimized for customer’s facility and to meet
customer’s requirements, Buhmwoo supplies the products
customized for its customers for productivity enhancement
and cost reduction.

improves the color of PO by decreasing the speed of corrosion on iron during pickling process, pickling accelerator that
increases the speed of pickling by accelerating the speed of removing scale, and carbon deposit inhibitor that prevents steel
carbon deposit during BAF annealing process after degreasing.

chemical resistance, and forming, etc. In addition, it is eco-friendly and reduces cost because it can be applied to a
steel sheet thinner layer than the existing high temperature curing and thick film (3-coat, 2-bake, about 30㎛).

Forming Oils
Forming Oils
When external force is applied to an object, its shape is deformed while
tension occurs. If the force is small, the shape of the object will return to its
original. However, if the force exceeds certain level, the shape is not recovered
and plastic deformation is created. This property is called plasticity. The
process of a material using this property is called plastic deformation.
Features
Buhmwoo produces and supplies forming oils through optimized design
(chlorine free) for automobile parts, large machinery parts, and aircraft parts,
which are hard to process, considering and the working property of each
product type and the environment safety of customers.

1. Forging Process
Forging process is used to mold desired shape and improve mechanical property of a metal material by putting the material
into between tools or metal molds and attaching them to compress the material. Depending on the work temperature,
forging process is classified into cold forging, warm forging, and hot forging.

2. Press Process
Press process is called stamping. It indicates all processes such as shearing, bending, deeping drawing, which is used to
create a container by putting into a die hole with punch, stretch expand, which is molded on a curved surface by applying
surface pressure on a board, forging, and extrusion. In this press, its friction conditions such as surface pressure, friction
surface temperature, and surface area increase rate between tool and material surface are not more severe than those of
warm forging, drawing, and extrusion, but this process has larger surface area against product volume than those
processes. Thus, if lubrication condition is not proper, this process may cause the damage of a material or metal mold.

5. Gear Oils
BW GEARLUBE BHG series are industrial gear oil with extreme pressure resistance, corresponding to KS industrial type 2.
They are used ranging from various airtight reduction gears to large gears (splash oil lubrication type) and to heavy load
hydrostatic pressure bearings (circulating lubrication). Carefully selected additives such as sulfur-based extreme pressure
additive are mixed with high pure lube base oil to effectively protect facilities in equipment where heavy load is applied.
