INTRODUCTION

“MODUL” is a tool holding system developed for handling of tools in machining centers.
In its split-design version “MODUL” consists of three group component parts:

  1. Basic holders and draw-bars
  2. Intermediate parts: extension, reduction and expansion parts
  3. Adapters – where the cutting tools are locked

View list of all component parts (below)

The split-design tool holding system is manufactured in three with 50, 63 and 80 mm coupling diameters. Sizes 63 and 80 are interchangeable.
The coupling system corresponds to the requirements for versatility, good stability, small radial run-out, as for cutting fluid supply through the tool.

HIGH FLEXIBILITY

The split-design tool holding system allows quick adaptation of the tool sets depending on the specific needs and type of machining required.
All component parts, with the basic holder excluded, can be mounted on any type of machine without considering the spindle taper or ATC design.
The high versatility is achieved through the use of a wide variety of intermediate parts and cutting tool adapters.

HIGH  STABILITY  AND  SMALL  RADIAL  RUN – OUT
Connecting different component parts together is performed by means of  a guiding stub which centers across two diameters simultaneously.
Tanks to the close tolerances between the parts involved, the total radial run-out can be kept to a minimum.
Parts are connected by means of a large, robust screw.
This makes the system  suitable for roughing, as well  as for finishing operations.

CUTTING EDGE ANGULAR POSITIONING

When the exact hole is being bored the cutting edge must be offset from the machined surface. It is therefore important to know its angular positioning. Since the separate parts are coupled only with a single driving dog, incorrect mounting is impossible and the exact position of the cutting edge is always known.

CUTTING FLUID SUPPLY THROUGH TOOL

The system, being furnished with central through-holes, drilled in the draw-bar and connecting screw, allows cutting fluid supply to the cutting area itself through the tool.

ECONOMY

Using such split-design tool holding system offers substantial economical advantages to its Customers. From one side, the number of parts, needed to machine several workpieces is smaller, which means – cheaper. On the other side, when change of production program occurs, the same tool set can be adapted. Therefore no additional costs are needed for buying new toolholders. And finally, in case new equipment is acquired, only new basic holders and draw-bars should be added to correspond to its requirements. All other component parts are employed on these new machines.
