ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a drilling machine, and more particularly to a drilling machine with vacuum suction table for precisely positioning.
BACKGROUND OF THE INVENTION
Typically, a conventional drilling machine comprises a base, a plurality of fasteners provided on base for fastening a glass plate on base, and a drill. Generally, it manually fastens a glass plate on base and then manually position a drill to above base prior to conducting a high-speed drilling process on the glass plate. It is seen that such manual fastening and positioning are not reliable and time consuming which further results in a short furlike glass edge, glass break, error, etc. occurred in an unfinished product during the drilling process. As such, a poor finished product with low precision is produced after a liquid crystal applying process. To the worse, it is possible for drill to penetrate through glass plate to damage drill and base both.
A need remains for an improved drilling machine with vacuum suction table to overcome the above drawbacks of prior art.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a drilling machine comprising a vacuum suction table for putting a glass plate thereon, a plurality of fasteners to fasten vacuum suction table on the glass plate, an adjusting screw for precisely positioning drill seat to above a desired position, a motor drive to provide a power for enabling drill to move down and conduct a high-speed drilling process, and a lubricating device for feeding lubricating oil on drill during operation so as to decrease drill temperature and dust occurred. With the improved drilling machine, numerous disadvantages of prior art, such as a short furlike edge formed on glass plate, glass break, and error, are eliminated, while providing a quality product with high precision as well as increasing efficiency and safety.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
