Factory renovation often requires upgrading of cement concrete floor。In order to keep the indoor clear height unchanged,，It is often necessary to mill the plant floor in advance according to the needs of transformation.，And then rebuild the ground.。

Many owners do not understand the milling process.，It can only be broken by hand.，It takes time and effort，The depth of the ground after planing is uneven.，High cost。Milling efficiency can be greatly improved by using milling machine.，Precise control of milling depth，Milling materials can be directly loaded and transported away.，It has obvious advantages over manual operation.。

Wittgen China，30 thumbs upApplication requirements

Milling in the workshop，The requirements for the milling machine are not only high discharge efficiency,，There are also the following requirements：

1. The cement concrete grade of the plant floor is C40、C30 is more common.，The milling machine needs to have the ability to mill to 4 with high efficiency~5 cm Depth；（Beyond this depth，The process of milling twice will be more efficient.）

2. Limited space in the plant，More columns，Equipment flexibility is required，Able to mill welt；

3. Engine Emissions Cleaning Required for In-Plant Milling，At the same time, dust as little as possible，Provide a relatively good working environment for construction personnel；

4. The receiving belt can have a large swing angle.，Trolley steering 90°Time，It can also be charged.，Achieve as much material receiving efficiency as possible。

Matching device recommendation

1 m Small Milling Machine Below Gear，In a project of a slightly larger scale，It often appears that the milling ability is insufficient.。Half-meter milling machine is due to its lower body height.，It is more suitable for the milling operation in the basement.。

Milling and planing of the ground of the corresponding large plant，Wittgen “Medium-sized milling machine series”：W 155 CFi / W 185 CFi ，In many plant floor milling projects，The milling efficiency can fully meet the construction requirements.，But also is more flexible than a large-size milling machine.，At the same time, due to low fuel consumption,、Low emissions，The economy is better。

W 185 CFi It is the model with the widest milling width in the medium milling machine series.，The standard milling drum is 1.9 m，Compared to its brothers. W 155 CFi 1 of.5 m For wide milling drum，Wider milling width for ground milling with not very high grade or napping items with small depth，It will be more efficient。

An empirical application case
One、Guangdong Zhaoqing Plant Ground Reconstruction Project Cement Pavement Milling

Milling depth：4 cm （Milling twice，Milling 8 in total cm）

Total area：1300 m²

Working hours：8 h

Fuel consumption：120 liters （15 liters/Hour）

Cutting tool：Wittgen W1-13/20A²

   Compact body design，The steering is flexible，Access to the plant，Do it with ease

   Right offset milling drum，Welt milling is easier

   Maximum swing angle of belt，60 left and 60 right°，At the end of the milling，Trolley steering 90°It can still feed smoothly

Thanks to the large swing angle of the belt，The working length of the milling machine is extended to the maximum，Reduce the number of times the machine goes back and forth to the work surface，And that efficiency is greatly improve。

   4 cm Milling depth，Milling two layers in total，Up to 8 cm

   W 185 CFi Monitor as standard

Except for the mirrors on both sides.，Equipped with two cameras，Monitor the left and rear environment separately, Through W 185 CFi Standard monitor for real-time display，Improve the omnidirectional field of vision for the operator，It's easier to control.。

   Automated sprinkler control and optimized spray design，O that the effect of spraying dust reduction is obvious.

From the milled road surface, we can see that the amount of water sprinkled by milling is not very large.，But the dust in the whole site is not big.，There is only some dust in front of the discharge belt.，The whole environment is very friendly to the operator.。

It depends onAutomated sprinkler control and optimized spray design，O that the spraying and dust settling effect in the milling drum bin is better.，Not mixed in the material。Of course，W 185 CFi Also available as an option VCS Vacuum dust removal system，Since then，Most of the dust has been sprayed and pressed in the milling drum.，The rest are sprinkled again at the belt to reduce dust.，The effect is better。

Strong milling capability，At ISC With the support of intelligent driving system，W 185 CFi Milling 4 cm The cement concrete floor works up to 6. -7 m/min The speed of，Completed the task efficiently.。

   Tool condition after milling operation

1300 m² After milling，The cutter rotates perfectly，The wear is estimated to be about 15% by visual inspection%Left and right 。“Delta 18”Milling drum technology，The cutting resistance is small、The tool rotates well，Therefore, the tool wear is low.、Low fuel consumption、High efficiency。

Two、Galling Reconstruction of Factory Pavement in Foshan, Guangdong

   Milling and planing close to the column of the workshop

Right Offset Milling Drum，Right driver's seat extends to the right，The operator can easily observe the milling edge.。

   Operate precisely，Avoid ground obstacles

   Milling speed up to 15 – 20 m / min ; It is very flexible to walk in the factory building.，It's easy to turn around，The operation is simple

   Flat milled surface

   9 hours，Completed 5300 m² Milling task
