Drilling Machine

What they are: Machines which major function is to perform holes in various types of  materials. For this the engine applies a high speed for one or more drills to be responsible for removal of  material desired. For the different drilling conditions required, were created different models of drills. Before choosing the ideal drill for the work to be performed should be evaluated the following aspects:

• Part shape;
• Dimensions of the piece;
• Number of holes to be opened;
• Quantity of parts to be produced;
• Diversity in the diameter of the holes of the same piece;
• Degree of accuracy required.

Classification of Drilling Machines

Portable Drilling machine
Feed force comes from the operator that forces the drilling machine  against the material, while the rotation comes from one's own motor drill. The drilling machine homemade are classified as portable.
It is commonly used in parts already mounted where the position of the place to be drilled prevent the use of more accurate drilling.

Sensitive drilling machine
Used for small perforations. The advancement of the mandrel occurs by means of a lever that the operator is moving slowly,feeling so advance the drill into the material. So sensitive is named.

Column drilling machine
The column drilling machine are characterized by a column of unionbetween the base and head. This arrangement allows the drilling of elements with the more diverse, singularly and in series.

Drilling machine multiple trees
Useful for work on parts that have to go through a series of operations such as drilling, boring, reaming and undercut conical and cylindrical.

Radial drilling machine
The tailstock system eliminates the need for repositioning the partwhen you want to run multiple holes. You can take the head of thebench at any point, reducing production time. Recommended forlarge parts to be drilled in locations remote from the periphery.

Multiple drilling machine single head
Are more useful in parts to be produced inseries in  need of drilling many points in one or more plans.

Multiple drilling machine multiple head
In these drilling machine more than one head attack the head piece to be drilled,eliminating the need to reposition and turn the part each time the drilling plan is changed. Are used to save time, since the totaldrilling time is  conditioned to the hole deeper.

Numerical control drilling machine
Operate according to a program, enabling greater accuracy and speed.

Bench drilling machines
Small machines where the advancement of the drill is done manually. Its engine has a capacity usually around 0.5 CV
