Eurotec will be there to grasp what’s interesting for microtechnique.



Microtools need excellent clamping technology

The demand for ever smaller components in industry is constantly rising. Yet micromachining follows its own laws. Tolerances must be very tight. This places high demands on the machining tools. An exact run-out and repeatability of the processes are the keys to success. The user can achieve this with the new Rego-Fix ER microsystem. This innovative tool clamping system offers the overall system very high run-out accuracy and optimum vibration dampening.

A decisive effect
The Rego-Fix ER microsystem was specially developed for high speeds on new generation CNC processing centres, and ensures ultra-high precision and excellent results in micromachining. One example of this is the tool manufacturer Fraisa from Bellach (Switzerland). Stefan Senn, application developer at Fraisa said: “In the overall system, every component in its special design is crucial to success. There is no point in using a high-performance tool if the clamping and machining system does not offer an equally high-quality performance. This means that the clamping tool has a decisive effect on the outcome of a process. This is particularly true in the field of microtechnology because high run-out quality and the reproducibility of the processes are of paramount importance here.”

2 microns that make the difference

Fraisa was looking for solutions for a new microsystem in this area. The tools with a 3-mm shaft diameter overheat during shrink-fit operations and their run-out cannot be guaranteed.
Michael Hirschi, a Fraisa ToolSchool employee: “A precise run-out is absolutely essential for the tool life. For example, if run-out accuracy is equal to 2 µm, I drill up to 10,000 holes using a drill with a 0.8-mm diameter, even a large feed rate. However, if the run-out is higher than 4 µm, I can only produce a couple of hundred holes!”

Balanced at 25’000 min-1

The special design of the Rego-Fix micromilling system allows the user to work with the ER MS clamping nut, which has been specially designed for ultra-high speeds. This clamping nut features finely machined contours on all sides, and this results in minimal residual unbalance. Because this nut does not feature a pull-out shoulder, the collet is pulled out by means of the special E MS type wrench.
It even ensures ultra-high run-out accuracy and minimum residual unbalance at the maximum speed of 80,000 min-1. Henning Neumann, Head of European Sales at Rego-Fix AG add: “The tool holders are balanced at 25’000 min-1 in G 2.5, and the system is much more precise than the competition because all Rego-Fix components are designed to work in perfect harmony with each other.”

Comprehensive tests
The tests performed by Fraisa focussed on noise factors, optimum cooling, accuracy of the overall system’s run-out and minimum play of the spindle. Different materials and vibration behaviour of the overall system were also fully tested. The results of the precision of the Rego-Fix microsystem were even better than expected.

High-frequency and much more besides!

Small, compact, energy-efficient, fast, vibration-free, precise …. the high-frequency spindles deliver a hand full of trump cards as they take their place on the precision machining marketplace. Why use spindles of this kind? A meeting at Meyrat SA with Mireille Barras, the Head of Marketing and Christian Walther, the Director of this company.


Particular conditions
Use of the high-frequency spindle is frequently determined by usage conditions. First case to highlight: machining which calls for a very high rotational tool speed (up to 80 000 rpm); In cases like this, which are becoming increasingly common, there is no other effective solution. Second case to highlight: shortage of space; modern machine-tools are becoming ever more compact, so it follows that spindle dimensions also need to follow suit.Since they are not connected to mechanical links (e.g. belts), they can be located anywhere with ease.  These points harbour some important implications. Firstly, the fact of not using a mechanical coupling delivers operation without mechanical shocks or vibration and this of course extends the service life of tools while at the same time improving the surface condition of the machined component. Secondly, with this higher rotational speed, faster rates of workpiece advance are achievable, and this helps to boost productivity.

Productivity is the key
The overall productivity of machine-tools is improving continuously, while the quality and resistance properties of the tools enable them to operate at ever higher speeds. Operations such as milling, drilling and thread-whirling performed as tailstock operations no longer need to slow down the overall machining process. For example, the time allocated to milling Torx heads on medical screws in a tailstock operationg must not be allowed to exceed the machining time of the headstock operation. High-frequency spindles therefore deliver a flexible solution to the practitioners involved in running successive series of production operations.
For the operator, the extended tool service life is of great benefit.

Quality, price and word of mouth
The balancing precision is accurate to within a few tenths of a milligram, so the service life of tools and word of mouth are key reasons underpinning the business success enjoyed by Meyrat SA. This is something of which Mr. Walther is convinced: “The quality of our spindles is reflected in the satisfaction levels of our customers. If the operator is satisfied with the operation and service life of his tools, and if Meyrat responds effectively whenever problems occur, we gain a good reputation for quality of service, and machine operators pass the word on among themselves!”

When 3% will make you over 20!

According to a widespread profitability analysis for CNC machining, the value of tooling represents up to 3% of the total value (see chart). Yet, a simple change at this level may have consequences worth several dozen percentage points in profitability. For a better grasp of this phenomenon, we spoke to Didier Auderset, CEO of PX-Tools, located in La Chaux-de-Fonds, home of microtechnology (Switzerland).

Calculable consequences
To illustrate the example which is the title of this article, Mr Auderset uses the production of this micro-reamer in carbide which not only enabled his customer to gain several percentage points in profitability because they were able to use higher cutting speeds, but in particular virtually abolished the 24% of setting and adjustment. With their former tools, the customer always had a problem with the reaming depth and was forever making adjustments. The geometry of the new reamer proposed by PX-Tools has the advantage of offering a limit stop… now there is no longer any need to adjust the depth. Simple! The new reamer is maybe more expensive than the old one but it brings with it a very clear improvement in profitability. […]

More service
To provide a real service for the customer, in addition to listening to their demands and providing a solution which meets their needs in a timely manner, the company also need to accompany them throughout the production process to avoid any tool stock-outs. PX-Tools provides a full service in this area with call-off ordering which involves the tools stocked by PX-Tools and its agents and delivered on request. The regrinding service is also available. 10 years ago, the service (in the most general sense of the word including listening and advising) only contributed to between 10 and 15% of the success of PX-Tools. Now it represents a lot more. A perfect illustration of this change is given by Mr Auderset when he addresses his employees: “your sole concern has to be the customer, if we provide him with the right service, the rest will fall into place.”

To conclude this brief presentation (there will be more in a further Eurotec issue), I would write this sentence that Auderset told me:
“There is more than just one way of doing things. From all the different options, we provide the one which best suits the requirements.”

Electrochemical milling

The trend towards miniaturization is advancing with ever increasing speed, and this also applies in medical technology applications. Ophthalmic surgery, neurosurgery and ENT surgery have long played a pioneering role in the use of microsurgical instruments. In ophthalmic surgery, especially retinal operations, microforceps 0.3 millimetres in diameter have been successfully used for a considerable time.

Significant technical and personal investment
Due to the demanding requirements, both technical and medical, applicable to microsurgical instruments, it has only been possible to produce these up to now with considerable input of technical and personal resources. For example, most of the microforceps currently available for ophthalmic surgery are produced by conventional spark-erosion technology or conventional micro-machining, both of which afterwards require costly manual finishing. To minimize the consequent high production costs, three companies, 1stQ GmbH (manufacturers of medical technology products), primeTEC GmbH & Co KG (R&D,  project management) and Ecmtec GmbH (R&D ECF technology and service providers) are treading a new path. This cooperative project aims to use the new ECF microtechnology (electrochemical micro-milling) to develop a new disposable micro-forceps for microsurgical use in the field of ophthalmic surgery. ECF technology makes it possible to produce metal micro-structures and micro-shapes without costly refinishing.

The prototype already meets all the requirements for a marketable microforceps. Project leader Markus Gäckle, CEO of primeTEC, is satisfied:

“The first prototype microforceps produced by ECF already demonstrates the extraordinary potential of this new technology, with which both simple and complex geometries can be produced to micro-scale in metal materials with extreme geometrical accuracy and without the need for expensive finishing operations. This opens up the possibility, which did not exist before, of making new, innovative micro-instruments, or even transforming known types of reusable micro-instruments, into qualitatively high-value disposable micro-instruments.”
