FLEXODRILL

  The FLEXODRILL drill holder can be programmed to the required angle in a CNC machine control system. Using the same drill and drill holder holes can be drilled at different angles and in varied directions.
     
  Operating guide: When the drill is located into the centring hole it is then manoeuvred sideways to the required drilling angle. A universal joint in the holder transfers the circular motion from the machine to the now angled drill holder. Feed advance is effected through two axes. FLEXODRILL will return to it's initial position when the drill is free of the hole.

Normally the drills length (C) should not protrude from the collet more than 15 times the drill diameter. The drill can protrude as much as 20 times the drill diameter if the feed rate is reduced and the material is suitable.
     
  FLEXODRILL was invented due to our own needs in the high-tech manufacturing workshop.

Drilling angel and RPM

This diagram refers to non-alloyed steel at approx 180 HB.
(These values can be increased with easy to work material).

 

RPM and feed rate should be reduced from
normal values for each drill dimension.

Cut samples of drilling

A short explanation to cut samples
of a
hydraulic valve block

Flexodrill has bin used on several holes when machining this valve block.

In figure 1 it is important to note that at position (a) (also in figure 2), (b) and (c) are critical areas where precision is required. Positions (b) and (c) have to perforate the hole wall so that they are connected to the longer hole. At (a) it's important that the wall is not perforated or even too thin and damaged by hydraulic pressure.

In figure 2 the holes are drilled to 15°, this is a simple hole where precision is required but only to connect with one hole.

Figure 3 is a difficult hole to drill because of the length of the drill bit in relation to it's diameter.

In figure 4 we drill a ø5 mm hole to a depth of 8,5 mm which is also threaded with an M6 tap to a depth of 5 mm.
