Optimal flute shapes are not determined by standard grinding wheels. Defining a flute profile for a spiral cylindrical tool as a 2D-DXF drawing is sufficient. This enables calculation of the suitable shape of the grinding wheel – all at the touch of a button and directly within the process definition for the flute operation.

Siemens, the Energy Sector in Duisburg with its famously high vertical range of manufacture covering, among other segments, turbines, compressors and ventilators, has always applied extremely high standards to its own production tools. Its in-house tool grindery, featuring two SCHNEEBERGER CNC tool resharpening shop, has for decades ensured this high standard.

Apart from grinding itself, the importance attached to the measurement and recording of measurement results is on the increase in the tool grinding segment. This includes measurements conducted after product completion and during the process in order to increase the precision of the product. Possible procedures include tactile measurement with a 3D probe, optical measurement within the machine, and external measurement using a measuring instrument.

On 2 October 2010, a delegation from the trade association representing Germany’s precision tool grinders paid a visit to J. SCHNEEBERGER Maschinen AG at its Roggwil premises in Switzerland.

Andreas Grabmeier, winner of the Grinder of the Year 2010 competition organised by the journal Fertigung and held at GrindTec2010, is looking forward to redeeming his prize.

With ARIES5, SCHNEEBERGER has introduced an extremely compact tool grinding machine, which despite a low purchase price covers an amazingly wide spectrum of machining processes.

Spline shafts are used where large impactive torques have to be transmitted by a combination of shaft with hub. The choice of an involute tooth form gives a substantial reduction in surface pressure on the tooth walls in comparison to other kinds of spline shafts.

Nestled in the quiet rolling hills of central Ohio is the little town of Walnut Creek. Home to a few hundred peaceful settlers, the place has also been home to Hiland Wood Products.

Gear-Cutting tools fall under the high performance tools category with respect to their shape and application, while meeting high requirements for profile accuracy, cutting quality, and tool life.

In one large machining center of a medium-sized company in the metal processing industry in Switzerland, 400 tools are in use. Of these tools, some 20% are fitted with inserts. Most of the inserts are milling inserts, a couple are part of a drilling or internal turning tool, and a few are part of a reamer. The tendency for fitting inserts is increasing. The larger the tool diameters, the greater the material removal capacity, the sooner an insert is the ideal solution; because a corres-ponding integral tool of the same dimension would be more expensive, regardless of insert changes.

Assembly optimization project M07

Over the course of the last two years, J. Schneeberger Maschinen AG has made great efforts to optimize the entire production process. Consi-derable investment has been made in new production means and implementation of organi-zational measures. Here we report on our project progress in mechanical assembly.

Modern complex workpiece geometries can only be produced at great cost when using conventional milling cutters. The company Hartmann CNC-Fertigungs- und Schärfservice in Kahla, Germany, is specialized in the production of special milling cutters.

A new chapter has been opened in the story of grinding wheel loaders for tool grinding machines. With SCHNEEBERGER‘s newest wheel changer, there are now 48 wheel packs available. Naturally, there is also room for the accompanying coolant manifolds and pipes in this new wheel loader.

An A-axis with through-feed feature enables long tools to be machined on machines with short travel. For example, on a NORMA grinder with an X travel of 400 mm, tool lengths of up to 1000 mm can be ground.

Grooving is a sensible cost- reducing factor within the turning process. At the same time, parting represents the most difficult and costly method of metal cutting, particularly when tough, hard materials have to be machined. odern parting-tools are characterized by various cutter and profile designs, particularly since a further machining stage, e.g. facing, profiling, slotting, etc. is usually necessary after parting.

Milling cutter variations

A new generation of milling cutters appeared on the market a few years ago: multi-spiral milling machines are cylindrical milling units with several cutters having different helix angles. The necessarily unequally divided milling cutters led to better, more stable milling conditions, thus significantly improving the milling capacity of high performance milling machines.

NORMA CFG

Many customers appreciate the versatility of the NORMA CFG. Once again, this versatility was impressively demonstrated at the EMO 2005. Equiped with a loader, an easyVARIO 5-jaw chuck (clamping range 1⁄4”–3/4”; 5–20 mm shank diameter) and the VARIOpalette, the automatic production or regrinding of tools of various diameters and in small batches is not only possible, but also economical.We also introduced automatic edge chamfering (K-Land). Finishing the tool in the grinding machine while it is still clamped in a fixture for highgrade boring tools saves a second operation, which often involves manual work. The chamfering operation follows the contours of the cutting edge exactly, the K-land width is determined by the operator in the program.

SIRIUS linear10nano Inserts

The SIRIUS linear10nano for inserts proved to be a special highlight at our EMO exhibit. The complete machining of on-edge triangle thread cutting inserts (profiling, grinding of periphery and chip breaker) in a single clamping was met with great interest. The indexable insert is clamped in the center of the tool with an arbor and is free for complete grinding on all corners.

SIRIUS linear10nano microTools

Another first was the introduction of our SIRIUS linear10nano for the microTools application. The SIRIUS provided additional evidence of its versatility and precision. The size, or rather, the smallness of the tools calls for specific solutions for the micro tool range. Starting with the tool clamping: the clamping chucks are fixed axially in the dividing head, but they are allowed to float radially. Concentricity is ensured with a prismatic steady rest and an additional rest under thegrinding zone.

EDGE-FILTRATION

The fascinating operating principle of edge-filtration was previously only available to large central systems. Schneeberger has teamed up with a well-known filter manufacturer to develop an edge filtration system according to our own concept. The result is the SCHNEEBERGER-ARO edge filtration system, a filter that impeccably prepares cooling oil for a single machine – in a compact and affordable form.
