A visit to Pentzold Metallbearbeitung und Musterfertigung in Chemnitz

Short distances, close ties – Holger Pentzold learnt and worked at Heckert and has also remained loyal to Heckert machines in his own company: “I know what the machines are capable of and that I can rely on them one hundred per cent.” His company, a service provider for precision machining, has been based at the ITC – the Chemnitz Industry and Technology Centre – for many years and is well worth a visit, and not just because of its proximity to today’s Starrag GmbH.

 

Pentzold Metallbearbeitung und Musterfertigung (PMM) was founded in 1992 by Günter Pentzold. His son Holger Pentzold has been running the company for 28 years, supplying foundries and companies in the automotive industry, agricultural machinery and general mechanical engineering as well as the hydraulics industry with precision parts. He explains: “We primarily manufacture series parts with varying batch sizes of 10 to 15,000 units, but also prototypes. Our in-house fixture and tool construction as well as a modular system for clamping fixtures allow us to react quickly and flexibly to customer requirements.”

“ With the Heckert H50, we achieve the required concentricity of 10 μm.”

The reason why the machining professional repeatedly buys Heckert machining centres is quite obvious. PMM has been located in the Chemnitz Technology Park (ITC) since 1999 – right next to the Starrag plant. “Nevertheless, we conduct research on the market for alternatives before almost every investment,” explains Holger Pentzold. “But it’s all in vain – we have repeatedly decided on universally applicable, horizontal Heckert machining centres.” This was also the case in 2018, when the entrepreneur started automated production with the then newly developed Heckert H50 compact machining centre including an integrated six-pallet system.

Beta testers just 500 metres away

“We took delivery of the H50 immediately after its initial presentation at the AMB and were effectively the first beta testers,” recalls Pentzold. “The proximity of our production hall to the manufacturing plant was extremely practical for Starrag and us. In the event of any problems, the Starrag technician simply had to cross a few halls and they were soon on site, where they were able to get an idea of the difficulties, which were then usually quickly resolved and incorporated into fundamental corrections.”

“ In addition to the high rigidity and damping in the basic structure, the thermo-symmetrical design should also be mentioned, which guarantees maximum accuracy.”

Automation further expanded

The machine was quickly utilised to capacity. As the 500 pallet size was too small for many orders, in 2022, Pentzold and his team decided to invest in a Heckert HEC 630, automated with an Erowa Loadmaster shelving system with 21 pallet spaces. A major purchase in every respect. This machining centre works with 630 mm pallets and allows components up to 1500 kg in weight, 1550 mm in diameter and 1250 mm in height. “It covers an even wider range of components than our old CWK630, which we replaced with it,” Pentzold is pleased to add: “We also opted for an SK50 Big Plus spindle with 7500 rpm for the HEC 630. The higher speed of this spindle increases the machine’s range of applications even further.” PMM can continue to use its existing tools in this spindle, but can also use tool holders with a flange contact surface if required. The existing NC programmes can also be reused with minor modifications.

Pentzold – Heckert fans for many years

When Günter Pentzold founded Pentzold Metallbearbeitung und Musterfertigung (PMM) in 1992, he was still employed as a fitter at the former Heckert plant. After work and at weekends, he used a second-hand Heckert CW500 to carry out small milling jobs in an old tractor workshop in the Ore Mountains. In 1999, PMM was one of the first tenants to move into the Chemnitz Industrial and Technology Park (ITC), which back then was built in the office tower and six halls of the former Heckert site. Business was successful. PMM invested in further Heckert machines. Today, Holger Pentzold is the owner of the company, which employs ten people. Like his father, he is completely convinced of the quality of Heckert machines. After all, he is familiar with their performance as a user, and he knows what's behind them: Holger Pentzold trained as an electrician at Heckert.
