At EMO 2023 in Hanover, machine builder Hainbuch will be presenting itself with a new image: “Today, we are a solution provider for the entire process: changeover, clamping, measuring and automation,” is how Stefan Nitsche, Division Manager Main Products, describes the company's range of expertise. Of course, clamping technology and set-up time optimisation are and will remain at the heart of the specialists for high-precision clamping solutions from Marbach. But with the acquisition of Vischer & Bolli Automation almost three years ago, Hainbuch has rapidly expanded its expertise in the field of automation. “Today, we support our customers throughout the entire process,” says Nitsche. “From workpiece loading to setting up or changing clamping devices, from clamping the workpieces to quality control through measuring processes. We are ready with solutions for all process steps, whether manual or automated.

Changeover: Quick changeover solutions speed up the process

Changeover solutions from Hainbuch — whether the Hainbuch system or the centrotex quick-change system — are easy to handle, save valuable time and thus costs. For the centrotex quick-change system, Hainbuch is now presenting another addition at the EMO: a new 3-jaw chuck. In addition to the Toplus and Spanntop chucks for O.D. clamping, the Maxxos and Mando mandrels and the compensating 4-jaw chuck, the 3-jaw chuck with its very low installation height completes the range of clamping devices. This means that the chuck can be changed in less than one minute — without alignment. This means even more flexibility in the machining process for small batches with frequent chuck changes. Another highlight is a new storage and handling system for centrotex products. With pallets, holders, transport trolleys and a set-up lift, the products can be stored and handled cleanly and easily. This also saves valuable time.

Clamping: Safe and rigid clamping ensures maximum process reliability

The invention of the Spanntop chuck in the 1970s marked the beginning of a new era in workpiece clamping. Since then, new and improved solutions have followed, which are now copied worldwide. The hexagonal geometry of the Toplus chuck was then transferred to the Maxxos mandrel to ensure even greater rigidity with higher transmission forces. At the EMO, Hainbuch is now presenting the Maxxos T212 mandrel for the first time. Compared to the proven Maxxos T211, the T212 without draw bolt and with new, improved technology is ideal for workpieces with blind holes or very short clamping lengths: no clamping length is lost due to the draw bolt. Thanks to the hexagonal pyramid shape, the Maxxos is the mandrel for the most demanding machining and promises 25 percent more holding force than the round mandrel and in some cases double the torque transmission.

Measurement: Stable processes thanks to integrated measuring technology

The process does not end with the machining of the workpiece. Continuous measurement and control of workpiece quality ensures process stability.

This can be done in separate measuring steps outside the machine, but in-line measurement is often more cost-effective and time-saving. Hainbuch's clamping devices with integrated measuring intelligence make such in-line measurement possible. They continuously measure workpiece diameter, temperature, workpiece contact and clamping force. Using non-contact data and energy transfer, the measured data is sent directly to the machine control where it is analysed. The control performs a setpoint comparison. If there are any deviations, a message is issued or a correction is initiated immediately. With the intelligent IQ clamping devices — available both as a chuck for O.D. clamping and as a clamping mandrel for I.D. clamping — Hainbuch increases machine availability and process capability and reduces upstream and downstream measuring processes. This increases quality and ensures a constant level.

Automation: Works even for low-volume and one-off production

Workholding is the logical starting point for successful automation: It simplifies processes and often eliminates process steps. Particularly in small batch and one-off production, changeover time often reduces valuable machine uptime. For these processes, automated fixture changeover makes automation a worthwhile proposition. With the zero-point clamping systems of the AC [automated change] line for turning and milling, Hainbuch offers tried and tested solutions.
