Description

Fine drill processing machine using automatic ultrasonic cleaning {FINE DRILL PROCESSING MACHINE USING AUTOMATIC ULTRASONIC CLEANING}

The present invention relates to a fine drill processing machine using automatic ultrasonic cleaning, and more particularly, to a fine drill processing machine using automatic ultrasonic cleaning capable of maximizing drill life by automatically ultrasonic cleaning a drill during drilling.

In general, the hole processing technology is the most basic method among the processing technology of machines, and it is gradually increasing in precision and speed in order to improve productivity.

In particular, the micropore processing technology includes electronic products, PCB, IC masks, watch industry and fine nozzles, optical fiber connectors, electronic parts for aerospace, medical optical devices, precision tools and gauges. The scope of application has been expanded to fields such as Gauge), and the trend is increasing in speed and depth.

In addition, micro-drilling should minimize the amount of infeed once in order to improve the drill breakage and machining precision, and thus have to have an optimized spindle rotation speed and infeed speed.

However, in order to find an optimized condition, time and investment cost increases, and even if it is processed with an optimized recipe, the sludge is fixed in the drill groove after several hundred holes processing, and thus the unsafe shape in which the drill can be broken has to be maintained.

A drill machine for such fine drilling is a machine tool that uses a drill as a tool to drill a hole in a workpiece.

That is, while the work piece is fixed to the table, the drill fixed to the main shaft performs a feed motion at the same time as cutting to make holes in the work piece.

Such a drill machine consists of a table on the saddle to be level with the floor, and the work piece is fixed on the table, and the drill is installed on the main axis so that it is perpendicular to the work piece fixed to the table, and the drill rotates and moves linearly while drilling Is done.

An important factor in drilling a product having multiple holes is to secure the surface roughness and mass production of the product by stably maintaining the drill life.

In case of fine drilling, when drilling less than π0.4, the tool diameter has an unpredictable processing category compared to the π0.45 drill. After processing, fine particles adhere to the drill surface and groove, leading to damage to the drill.

In addition, in the process of fine drill (π0.4 or less), which becomes smaller and smaller, the drill groove space and torsion angle are kept narrow, so that the chip discharge according to the conditions is not smooth, and the sludge adheres continuously as the number of hole processing increases. After tens and hundreds of holes are processed, the sludge is formed at the maximum value in the drill groove, resulting in the drill being broken.

In addition, the sludge is fixed inside the tip angle of the drill and the torsional grooves, blocking the inflow of internal coolant and increasing the rotational torsional load due to friction, which leads to damage to the drill.To this end, it is possible to manually wash the drill in the middle of processing. Setting and other program rework is required, and there is a high concern that product defects may occur due to increased mass production time and user error.
