Big Kaiser, a specialist in precision tooling systems and solutions for the metalworking industry, is introducing its Hydraulic Chuck Ultra Precision. The new chuck, which is suitable for machine shops that require the lowest possible runout in high-precision milling, is available in the UK from Industrial Tooling Corporation (ITC).

With Big Kaiser’s hydraulic clamping system for high levels of concentricity, the company guarantees runout of less than 1 µm at 4xD. This ultra-low runout does not drift, even after intensive use, whereas some shrink-fit holders become less accurate after each clamping, reports ITC.

Clamping with the new hydraulic chuck is easy and safe, requiring only an Allen key. This design makes it straightforward and quick to change tools in the machine. With no hot-clamping machines required, users can extend the life of the tool holder indefinitely, reducing costs and minimising the environmental impact of holder replacement in comparison with shrink-fit holders.

As part of Big Kaiser’s HDC (hydraulic chucks) series, the new chuck provides precise clamping in 3, 5 and 6mm diameters.

“Based on our decades of experience and know-how, the new ultra-precision chuck delivers the excellent accuracy that our customers demand,” says Giampaolo Roccatello, chief sales andmarketing officer for Europe at Big Kaiser. “Shrink-fit holders may cost slightly less up front, but when you factor in the time wasted and the cost of heating and cooling equipment, it’s clear that hydraulic chucks are a more economical option over their lifetime.”

In many sectors that require sheet metal handling, vacuum suction cups have become an essential element of safety, reliabilityand productivity. With the company’s new CTC high-performance bell-type suction cups, Covalsays it is bringing manufacturers the best of both flat and bellows suction cups to enhance system efficiency.

The main feature of new CTC suction cups is the bell shape. This design has the strength and anti-slip qualities of flat suction cups, with the added abilities of bellows suction cups to grip complex or angular shapes.The CTC cup series has large deflection capability, adapting easily to gripping a variety of workpiece shapes.Furthermore, anti-slip cleats make it easy to move heavy, oily sheets quickly and efficiently, while their central stops ensure the tight gripping of thin sheets without deformation.

Typical applications include feeding machines such as folders and cutters, or picking up sheet metal or parts for transfer to stamping presses and storage. CTC suction cups are particularly suitable for use in the automotive sector, in processes that include stamping, fitting and assembly, for example. The company says it has long-standing partnerships with major car manufacturers, supplying them with products that meet their quality and productivity expectations.

CTC bell-type suction cups are available in four diameters from 40 to 100 mm and various mounting configurations (3/8G male or female and 32 mm square), to suit all types of application. Coval makes all of them from TPU (thermoplastic polyurethane) for resistance to wear and oil.

At September’s EMO 2023 exhibition in Hanover, Haimer presented a variety of innovations in the area of tool clamping technology: from the Micro Collet Chuck and the High-Performance Chuck, to the world premiere of the company’s Hybrid Chuck technology. There were also new software versions for Haimer shrink fit, balancing and pre-setting machines, enabling smooth data exchange among each other, and with machine tools and automation. The highlight at the booth: an impressiveautomation cell for tool set-up, including an automated guided vehicle to and from the machine tool.

As a world premiere, the Haimer Hybrid Chuck features new and patented technology that combines the advantages of two clamping worlds: the vibration-damping properties of a hydraulic chuck with those of a high-precision, high-performance shrink-fit chuck.

The new Micro Collet Chuck, which also made its debut at EMO, is suitable for shank diameters from 1 mm and meets customerrequirement for maximum runout accuracy with simple handling.

Moving forward, all Haimer shrink-fit, balancing and pre-setting machines will receive a new software version that includes a bidirectional interface for connection to the new Haimer Tool Room Manager (TRM). This new software monitors the online status of all devices in the tool room, documents the processes and monitors compliance with the specified tolerances. An optional OPC-UA interface, client or MQTT Connect interface standardises access to machines, devices and other systems, and enables manufacturer-independent data exchange.

On the Haimer Tool Dynamic balancing machine, the new software also opens the door to automatic indexing. For this purpose, a small gripper features in the new models that rotates the tool awaiting balancing. The software does the rest without any further manual intervention of the operator.

Headquartered in Austria, Amann Girrbach manufactures equipment to produce not only dental prostheses such as abutments, crowns, veneers and bridges, but also dentures. In its latest production system, the Ceramill Matik, the company is using a zero-point clamping system from Roemheld group company Stark Spannsysteme. The solution ensures enhanced repeatability when positioning raw material for five-axis milling of the complex profiles that characterise the prostheses. The products are available in the UKand Ireland through Roemheld UK.

Intended for extended periods of unattended production overnight and at weekends, the new machine is an intelligent solution that combines three operations in one: milling at up to 100,000 rpm, cleaning and automatic storage.

Marcel Humml, senior manager operational excellence, says: “The Ceramill Matik incorporates a five-axis machining centre with a 36-workpiece changer, whereas other products on the market have a maximum of 12 workpiece positions and are considerably more expensive.”

He adds: “When testing the Stark zero-point system, we concluded that we would like to have a few modifications. We didn’t want any visible screws and we preferred exposed sides so that water and dirt could run off better.Due to our compact holder size, we also requested a smaller support surface to save space. Stark undertook all of these modifications in their customised solution.The co-operation with Stark during the development phase of Ceramill Matik was unbeatable; the relationship really couldn’t have been better.”

Stark says that its zero-point product is for metal component machining on a factory floor and not originally intended for a small production centre producing fine, delicate parts.However, the company was happy to make the necessary adaptations to support automation in the dental sector.
