In its production facility, complex parts are machined to high accuracy on a Mazak VCN 530C vertical machining centre and through the addition of a 2-axis CNC rotary table from Switzerland-based Peter Lehmann AG, the company can machine parts on five sides using five axes.

The company has enjoyed a close business relationship with Mazak since 1979 so not surprisingly Loesch"s ground floor houses six Mazak CNC machines – the latest being a 3-axis VCN 530C VMC. Following the purchase, a CNC rotary table combination from Peter Lehmann was added to the set-up to enable 5-axis machining.

However, a true 5-axis machine wasn’t an option for Michael Loesch: “Rocker-mounted rotary tables are usually pretty small – but the alternative was to spend a lot more money on a larger machining centre,” he reveals.

A 3+2-axis approach is less expensive while offering a greater flexibility: “For us the Mazak VCN extended by the Lehmann rotary/tilting table is the perfect solution,” Mr Loesch enthuses. “It even leaves enough room to accommodate two more vices on the machine table, thus providing further clamping options for simpler workpieces.”

To the Loesch team, the 1,300 x 550mm table was of particular importance as it can accommodate the Lehmann CNC rotary table and still provide enough space for two (125mm) vices.

Supported by the Swiss rotary table specialist and German sales and service partner IVO Oesterle, the team selected the T1-510520.RR TOP2 2-axis model. “The Swiss quality won us over from the start,” Mr Loesch recalls. “With regard to performance and suitability for digitalisation and Industry 4.0, we simply didn’t need to consider any alternatives.”

3D CAD data of the CNC rotary table was submitted to the team beforehand, so a matching workspace concept could be established via the in-house CAD system.

The 2-axis Lehmann T1-510520.RR TOP2 rotary table is 711mm long, 301mm wide and 250mm high. It clamps workpieces of up to 340mm in diameter which is more than enough for Loesch which mainly processes small to medium-sized workpieces up to cube edge dimensions of around 150mm.

In practice the high positioning speed of the rotary/tilting table is another significant benefit: “If possible we use one single tool, e.g. a chamfer milling cutter, to execute all operations in sequence, turning and tilting the workpiece than repeatedly changing the tool.”

“This required up-front collaboration between Lehmann and the Mazak control system developers but the result was well worth the effort. I can now program our VCN 530C with its 2-axis rotary table just like a 5-axis Mazak Variaxis which reduces programming to a fraction of the time. The productivity gains are significant – particularly for single and small-series parts. Typical batch sizes for us about between 20 and 200 pieces.”

Michael Loesch is very satisfied with his investment: “Thanks to the Mazak VCN 530C, the Lehmann rotary table and the other options we specified, we have made considerable time savings and reduced the effort required for re-clamping, thereby freeing up our machine operators to take care of other tasks,” he states.

Next on the agenda is an automated system to feed the VCN, but the Lehmann rotary table is already ahead of the game because it offers media channels to facilitate the remote control of automatic clamping systems.

“The force clamp on the rotary table is already pneumatically controlled and the two vices on the machine table will then be converted from manual to hydro-pneumatic operation,” Mr Loesch concludes. “This will allow us to fully machine all six sides without any manual intervention. This is definitely the way forward for us.”
