Trendsetting Innovations of The SAACKE Group

Whether having twist drills with 40 µm diameter or 630 mm cutting lengths, SAACKE is your one and only destination for a creative solution in the complete manufacturing and resharpening of tools.

Historically, The GrindTec Exhibition is considered to be the ideal place to showcase innovations in the field of grinding technology. Hence, a good reason to introduce our newly developed Saacke Tool Grinding Center Model UW I G held in Augsburg. Saacke’s latest generation of a production machine is designed with a spindle capacity of up to 36 kW, a 12-station grinding wheel changer with an extremely short changeover time, and a CNC controlled steady rest. The outcome of this solution allows the complete grinding of tools up to 630 mm in length. A variety of loading systems with highly developed clamping concepts put the finishing touch on this innovative machine concept.

In addition to this new premium product from the think tank of SAACKE, the highly successful CNC Tool Grinding Center Model UW I F will also be exhibited at the GrindTec. The UW I F is designed for re-sharpening and manufacturing of tools up to 20 mm diameter. SAACKE has achieved a high degree of automation for the manufacturing of small lot sizes with the integration of a grinding wheel changer and a PICK-UP-loading unit in the working space of this compact machine. An interesting result for the user includes: Short changeover times of the grinding wheels and a low-manned operation. Furthermore, the necessary spindle gets its power through the use of a direct-drive motor spindle having a peak capacity of 16 kW.

An Extremely Productive “Duo”

Both grinding centers can be equipped with Automatic Chain-Driven Tool Loaders. In these highly flexible systems, the 64 & 160-tool devices can be stocked chaotically. Multiple collets having different ID’s required for the various tool grinding processes are also stored in the loader and will automatically be changed. Thus, tools with varying diameters in HSS or Carbide can be loaded and unloaded by the loading system. The stocking of the loader and the programming of the tool data can be done in parallel during the grinding operation. The result: minimal machine idle time.

A Second Development and Introduction

Simultaneously, the unveiling of a newly developed machine from TTB will take place. The reputation of these machines for micro and small tools is almost legendary. Tools from 0.02 mm to 16 mm diameter can be manufactured with very high precision over the entire range. As the demand for smaller tools continues to increase, so does the attention needed regarding the cost basis of the investment, which we have now solved. With the development of this TTB Evolution, we have managed to improve the price and performance ratio more effectively.
4-fixed and internally mounted grinding spindles provide the accommodation for up to 12 grinding wheels in one configuration. With greater axis travel lengths, further improved positioning accuracy and a tool loading system for up to 1,000 tools, you are well prepared for future challenges.

Networked Technologies

Without suitable software systems, complex work processes today are inconceivable. SAACKE is relying on the NUMROTOplus® programming system of the NUM AG located in Teufen, Switzerland. Working in close cooperation with this experienced company, SAACKE has participated in the development of this system from the onset and has contributed to a comprehensive transfer of our grinding knowledge. On the topic of accurate measurement and documentation of all important tool parameters, SAACKE works together with ZOLLER, the specialist located in Pleidelsheim, Germany. The ZOLLER measuring machine, Model Genius 3, can be directly connected with the SAACKE grinding center via an online interface. To inspect the tool, the tool is merely clamped in the ZOLLER measurement device, where measuring automatically takes place. All of the critical dimensions of the cutting tool are taken automatically and directly from the grinding center and do not need to be re-entered. The measurement results are stored electronically and/or contained in an expression and can also be exported back to the SAACKE grinding center.

The fully automatic calibration of the entire grinding center is catching on more and more. The SAACKE calibration system perfectly determines the entire machine geometry within minutes and automatically transmits its results to all required software modules. This procedure takes control of the machine geometry, thereby reducing the need of program by program offsets. For companies adhering to ISO-9000 Standards, the Automatic Calibration System simplifies your documentation process.

Back to the Future

SAACKE has remained ever faithful to its origins and has successfully developed its core competence over the decades. The focused combination of tool manufacture and mechanical engineering creates synergy, as only a few companies have achieved. With the current range of machines and a wide range of precision tools, the philosophy of the company will continue to obtain dialogue with the customer and implement solutions for its future.
