Anchoring of a lathe in fixed positioning for long-term installations, on light floors.

Anchoring of a lathe in free positioning for long-term installations on solid floors.

Anchoring of a lathe in anti-vibration positioning for provisional installations.

The anchoring of any machine is key to ensure its proper performance and extend its working life, therefore, in this article we will explain how to proceed according to the needs of each possible type of installation of a Pinacho ML Series lathe.

Pinacho ML Series lathes are manually controlled lathes with an electronic speed variator that allows selecting the required cutting speed at any time, achieving better surface finishes, optimizing tool consumption and improving machining performance.

The new ML models stand out for their precision and useful life, being versatile machines for both maintenance and production work.

How to anchor a conventional lathe to the floor?

The first thing to consider is the structure and the particularities of the workshop or space where the lathe is to be installed. Is it a long-term location or just a temporary one? In the case of a permanent or long-term installation, it is essential to know whether the base, that’s to say, the floor where the lathe will be anchored, is light or solid, because depending on this, one type of installation or another will have to be required.

In the case of a long term installation and the floor where we are going to anchor the lathe is light, we will have to make a fixed positioning anchorage. If, on the other hand, the anchoring base is solid, a free positioning should be applied.

What happens in the case of a temporary installation? In this case, an anti-vibration positioning anchor must be installed, in which case it does not matter whether the base is solid or light.

In summary, the Pinacho ML Series lathes can be anchored to the floor in three different ways, depending on the needs and possibilities of each user.

How to anchor a lathe in fixed positioning?

As previously explained, this type of positioning is only recommended for long-term installations. This is because foundation work is required. Therefore, the user must make sure that he can carry out this work. Sometimes, when the workshop or lathe installation site is not on property, it is necessary to request the owner’s permission. In the case that the installation site is the owner’s, obviously, there is no problem.

In addition, this type of fixed positioning anchoring is only necessary when the floor base where the lathe is to be installed is light.

These are the steps to follow to anchor a lathe in fixed positioning:

When the floor has a light base, it is recommended to make a previous foundation.
If the lathe’s base is solid, we can anchor it directly with bolts using the free anchoring type.
The conventional Pinacho lathes are equipped with special steel platens only suitable for solid base floors.
To make the foundation, when the base is light, we will make square holes of 200 millimeters on each side and 250 millimeters deep, approximately.
We will fix reinforcing bars to platen suitable for this type of foundation.
We will place in the holes the reinforcing bars attached to the platen, aligning them with the centers of the leveling points.
In the Technical Manual of the lathe supplied with the purchase, the distance between tightener devices is specified.
We will fill the holes with concrete, in so that the platen will be perfectly fixed to the floor after the platen has hardened.
With the lathe in elevation, we will place in each leveling point the rods of each one of the tighteners, from below.
Once this is done, we will fix the locking nuts of each rod on each leg of the lathe.
Gently lower the machine onto the forged platens on the floor, until they coincide with the bases of the rods of each tensioner.
Finally, we will weld the base of the rods to the platens.
The lathe is now ready to be leveled.

To be considered:

When anchoring by fixed positioning, the rods must never rub against the internal hole of the adjustment device.
The rods and platens must be chosen by the user according to the foundation to be laid.

How to make a lathe anchor in free positioning?

This type of positioning is recommended for medium to long term installations, as it requires drilling of the floor with bolts. This type of free positioning anchor is only suitable when the floor base where the lathe is to be installed is solid.

These are the steps to follow to anchor a lathe in free positioning:

Conventional Pinacho lathes are equipped with special steel platens.
The platens must be aligned with the centers of the leveling points.
The distance between tensioners is specified in the Technical Manual of the lathe supplied with the purchase.
Anchor the platens with bolts on a strong foundation base, such as the floor of the installation site.
With the lathe in elevation, we will place the rods of each of the tightener devices into each levaling point from below.
Once this is done, we will fix the locking nuts on each rod of each leg of the lathe.
Gently lower the machine onto the platen anchored to the floor, until they coincide with the bases of the rods of each tensioner.
Finally, we will weld the base of the rods to the platens.
The lathe is now ready to be leveled.

How to anchor a lathe in anti-vibration positioning?

In the case of a temporary installation, an anti-vibration positioning anchor should be used, in which case it does not matter whether the foundation is solid or light.

This type of anchorage is ideal for training centers, small workshops or when foundation work or drilling of the floor with bolts is not desirable or not possible.

These are the steps to follow to anchor a lathe in anti-vibration positioning:

This is how a Pinacho ML lathe is placed on the floor in ANTI-VIBRATING POSITION.

When drilling the floor on which we are going to position the machine is not an option, we can use anti-vibration elements that will help to stabilize the machine.
With the lathe in elevation, we will place the anti-vibration elements at each leveling point from below.
Once this is done, we will fix the lock nuts of each anti-vibration element on each leg of the lathe.
Gently lower the machine onto the floor.
The lathe is now ready to be leveled.

To be considered:

When anchoring by anti-vibration positioning, the rods of the anti-vibration elements must never touch the internal bore of the adjusting device.
These anti-vibration elements are not supplied with the lathe. They must be purchased separately.
