ACTech - Freiberg
m&h Case Study ACTech - Freiberg

Measuring away rework!

By measuring workpieces, while still clamped on the machine, ACTech has eliminated sources of error and drastically reduced reworking of close tolerance parts. Now 12 machines have been equipped with touch probes and software from m&h.

“m&h’s 3D Form Inspect has helped us a lot,” Jan Wasserfurth, mechanical machining team leader at ACTech, states at the beginning of our conversation. For years, measuring workpieces while they are still clamped on the machine has been the daily routine at ACTech.

ACTech stands for Advanced Casting Technologies and the state of the art facility in the Saxon town of Freiberg has specialised in engineering, construction and prototype machining mainly for the automotive, aerospace and machine construction industries. They use cutting edge technologies to manufacture metallic prototypes complying with product features such as laser sintering of Croning® moulding material and direct milling of moulded material for essential mould making procedures in rapid prototyping. From drawing to casting and finishing to ready-to-install components, the company offers the complete range of prototype manufacturing using aluminium, iron, steel or customer-specified special alloys. More than 370 employees work at the company that was founded in 1994 and they are currently looking for additional staff.

Machining of metallic prototypes takes place in their own workshop. Since batch sizes are usually between 1 and 10 components with continuously increasing precision demands, they considered measuring on the machine at an early stage. Starting in 1999, ten 5-axis machining centres, one 3-axis machining centre and one turning/milling centre have now all been equipped with m&h touch probes.

ACTech also uses the m&h 3D Form Inspect software that compares the workpiece with the target specifications from the CAD drawing using freely definable contours and geometries. Contour...
