System FH and BFH

We produce round and flat form tools for all machine types, out of HSS or carbide-tipped! All materials used are of exceptional, well-established quality. We grind our profiles optically or by CNC, on sophisticated Swiss or German machines.

Advantage:

With the help of a magnified profile drawing we can control the profile on the tool visually or by camera.

Our own distortion correction software, which takes into account clearance angles and top rake angle on the tool, makes it possible to correct distortions when producing the profile drawing and the CNC-programme.

Profile drawings are being plotted with a precision that can not be achieved in a manually produced drawing.

Summary:

Each profile tool we produce gets its own specific production number, which is printed onto the tool. If you to re-order and give us the production number, we have instant access to all required data of the tool.

Your advantages:

• Shortened delivery time!
• Rationalized production - form grooving is faster than turning!
• Easy control: With a precise form tool it is enough to measure one spot of the component only.
• Constant quality.

Turning

The great diversity of plastic types which have also the most diverse cutting characteristics pose cutting problems for many plastic machining operators.

Dieterle recognized the problem and developed insert types for all plastic requirements, for soft and elastic plastics to rigid, tenacious and worn-out plastics.

These different kinds of inserts are shown together with the appropriate tool-holders in the catalogue Universal System For Plastic Machining.

There can be found sharp cutting blades as well as sharp long turning inserts which have big cutting depths. Also coatings, especially diamond coatings come in to operation when machining plastics. Herby we achieve a significant tool-life.

Poliangolar

What it Does

Poliangolar is a rotary motion device suitable to machine blind or through holes and external profiles with regular and irregular polygonal sections. In addition to the standard profiles, such as hexagons, square and Torx, on request our toolholders are used to produce special serrations, involute and toothed splines as per DIN 5480 - DIN 5481 - DIN5482, SAE J500, ANSI B 92 1st 1976 CUNA etc...Poliangolar is able to machine steel, aluminium, stainless steel, brass, titanium, bronze, plastic, and other alloys.

What it is Made

Poliangolar is made from hardened steel and the shank is induction tempered and then precision ground. The tool spindle is fitted with high precision bearings suitable to support axial and radial thrust.

How It Works

Poliangolar's tool spindle is mounted in the body of device with a specific angular orientation to gives to the tool a “hunt” rotary motion.Prior to broaching operation, a pre-hole should be drilled having slightly larger than the inscribed circle for a regular polygon, or a pre-slot in the case of an irregular polygon. Holes of different sizes and shapes can be successfully cut by simply replacing the cutting tools, which will have the same across section as the desired profile.

The attachment is supplied with a lever which should be used whenever the polygonal slots require a particular angular position. The Poliangolar is so simple to use because no templates or fixtures are required for it's efficient operation.

On What Machines

Our toolholders can be installed on any machine tools, traditional, CNC lathe and transfer, allowing to complete the workpiece without further operations. The range of equipment is available with standard shank (M.T., cylindrical, Weldon), also ISO / DIN (VDI, HSK, BT-MAS) and/or special shank on request.

Dragging lever's Use

Where possible, the use of dragging lever is always recommended, it is used to:

• Position the tool in order to orient the side or edge with respect to a particular reference
• Prevention of, in particular in the case of deep grooves, the twisting of the tool and possible spiralling of the required profile
• Avoids putting the tool under unnecessary stress, jeopardising both the machining itself as well as the finishing of the part and, as a result, the life of the tool.

The supplied lever may be replaced by any high strength screw or other suitable equipment and must be screwed into the threaded hole opposite to the tool blocking dowel.
