Engineering embraces a fine, interesting, an outstanding world. Every single machine used
now days derive from contributions made by people who have dedicated their lives to discover
the world of engineering. A very interesting feature is the development and evolution of these
machines used. As many current engineers can account, before the impeccable breakthrough in
technology, most machines available in the market had to be used manually. This represented a
great loss in production due to the extended time it would take to create a piece of work, as well
as the common human errors that made the pieces ineffectual. On my visit to the 24th Taipei
International Machine Tool Show held in Nangang Exhibition Center, I was able to experience the
technological advances that have made these machines work-friendly and efficient. Most of these
apparatus are equipped with software that will make the machine able to maximize their
production. Another outstanding feature is that almost every machine in the show was certified by
the International Organization of Standardization, which makes them more liable for the labor.
While I was cruising through the aisles there were two machines that caught my eye. One of them
was the CNC Turning Milling CT2-65YM developed by ChiahChyun Machinery Co., LTD. and the
Heavy Duty Precision Lathe X-33210 created by Win Ho Technology IND. CO., LTD. These two
machines are not only almost perfect in their performance, but they also have a reputable design.
The first machine that I was
interested in was the CNC Turning
Milling CT2-65YM developed by
ChiahChyun Machinery Co., LTD.In the
entrance, I was greeted by a very nice
gentleman Derrick Yu. I turned toward
the machine and he began to explain
me the importance of having this tool in
my company. Due to the fact that was
naïve in the topic, he first gave me a
small background of the company: “CHIAH CHYUN MACHINERY CO., LTD. is one of the most
professional manufactures for Twin Spindle Twin Turret, CNC Lathe, CNC Auto Lathe, CNC Turning
Center and Sub Spindle Lathe in Taiwan. They are the first company to be certified by ISO 9002 for
its Automatic Lathes and CE quality certification in Taiwan.”("CNC Lathe - Chiah Chyun Mechinery
Co., Ltd - HD Video of Twin Spindle Twin Turret, CNC Lathe, CNC Auto Lathe, CNC Turning Center &
Sub Spindle Lathe Manufacturer in Taiwan.)

2. Before introducing the CT2-65YM, it is important to explain the main functions of a
Turning Milling Machine and which items are produced using this. “Milling machines have two
main parts. The head holds the collets, which hold the tools used to mill the materials. The head
moves up and down on the "Z" axis and the tools are spun by a motor. The motor is either a
variable-speed motor, or a system of pulleys that is used to vary to the speed of the tool. The table
moves on two axes, the X and the Y. The table is moved manually by hand-wheels across the X-Y
plane to position the material under the head or move it against the cutting tool.”(What Is a
Milling Machine Used for? | eHow.com)The most common milled items are car engine blocks.
They are first cast from steel or aluminum, and then precisely machined on a mill. The engine head
is also milled before assembly, as are the valves, camshaft and pistons. Due to the fact that items
such as the mentioned need to be efficient and should not contain any error, milling machines
such as the CT2-65YM should be used in production.
The CT2-65YM is quite an excellent machine and therefore
following are the descriptions that make it stand out among the rest of the
milling machines. The most important thing is that it has a multi-axis
turning center for profitable production. Among the specifications of this
feature we can find that the CT2-65YM is composed of 16-position upper
and lower turrets. There is also a C-axis for elevation of turret. The massive
45° slant bed features maximizesstability. The CT2-65YM is full linear on all
axes. Its built-in type is composed by 4000 rpm main and sub spindle. In
order to avoid any overheating, this machine is equipped with an atomized
and modernized oil mist cooling for gears in turret making it more efficient
and avoiding constant oil refill.The following table included is to aid on
more specific details that make the CT2-65YM the machine needed at work:

5. As explained by the table, the CT2-65YM is suitable for any type of work. In addition to
these outstanding features, the company also offers additional equipment to optimize the
operational and physical system. The following tools can be also added: 6" hydraulic chuck, axial
and radial live tool holder, voltage stabilizer / transformer, high pressure coolant device,
Mitsubishi Robot, oil mist re-collector, and a bar feeder. Of course these supplementary objects
are for purchasing.

6. Even though the price of the machine was not revealed due to competition among other
companies, the CT2-65YM is a machine worth the investment. It will not only improve the
production flow, it will also provide the best quality products.
After exiting CCM, I kept wondering around the place, watching a lot new handy gadgets,
when suddenly I saw a gigantic machine. I walked towards it and stood stupefied by the
magnificent job the machine was performing.
The machine was the Heavy Duty Precision Lathe
X-33210 created by Win Ho Technology IND. CO.,
LTD. This company is located in Taichung
Industrial Park. They have more than 10 years of
experience in the manufacture of high quality
precision lathes. The precision lathe “is a
computerized lathe used to create detailed solid
objects from a single piece of wood or
metal.”(What is a Precision Lathe?)This machine
uses sophisticated computer software.The precision lathe can produce a near-finished product
with minimal waste. A lathe functions by spinning the raw materials while cutting, drilling, sanding,
knurling or deforming. The use of a lathe produces a finished product that is symmetrical along the
axis of rotation.A precision lathe is able to cut and shape a material to within 0.00254 cm of
accuracy. The cylindrical basis of the lathe means that the material is secured at each end and the
product is created by the removal of materials from the solid item. Some products that derive
from the precision lathe are baseball bats, table legs, poles and a wide range of ornamental pieces.
The Heavy Duty Precision Lathe is an amazing machine with features beyond the ordinary
precision lathe. This machine has improved Headstock. All gears and mandrel are made of alloy
steel with heat treatment and precision ground. Thanks to this, the rotating type speed changing
system is easy to operate. The spindle of 153mm, 230mm (OPT) is supported by 3-point precision
bearings. Another improvement that can be seen is the universal gear box design. With this new
gear box, the precision lathe is able to cut metric thread, imperial thread, module thread without
changing the gear. The apron and saddle were also optimized to obtain a better result. The apron
has cross and longitudinal fast speed design for auto distance skip-off. It was also built longer and
wider slide for carriage stronger cutting. The apron and saddle now include a special safety device
for any overload. Another advantage is the central lubrication system that can be operated
manually or automatically. Finally the Bed was enhanced with high tensile ribs structure. It is now
a 3V bed design for durable precision. The one piece structure lathe bed enhances the machine life
and working performance. In addition to these enhances the following table gives a description of
other details that are included in the new model:
