Timeline

2014

 TEH-CUT is finding new jobs in tools for composites,and new customers for aluminium dye casting . We are buying new machines, HAAS  line this time. We boght program Tebis as well.

2013

Again, the largest machine arrived, this time really large: a Portal Milling Center for parts up to 12t, dimensions 2,4x2,8x1,0 m. The machine is a "must-have" since our business continues to grow.

2012.

We had discovered new markets: tools for forming composites, large aluminium dies and machining fancy parts for plains.

2011.

Hermle Milling Center with robo-cell is state of the art. We are just watching perfect parts coming out of the machine. We started to calculate 'First time out' parameter, meaning no rework, repair, manual enhancing, and now we have 98% Yield continuously. You see what robo can do.

2010.

New qualification for the Leaf Springs which hold the fuel assembly in tension against vibration in the reactor. The material is Ni-alloy, needing special cutting tools geometry and coating. The visual criteria to prevent initial cracks in springs are 'No pits, no scratches under magnification 10x'. Large quantities asked for statistical process control and sampling plans, which meant a new discipline for quality personnel.

Steinel and Maho, 5-axes milling centers are put in process for leaf springs as well as a new EDM wire machine and 4 new bending dies on press machines.

2009.

Welding qualification for nuclear parts took us 6 months.

New qualification for Debris Filter Bottom Nozzle influencing pressure drop in the reactor asked  us to drill 650 holes with chamfers on both sides with locations tolerated to the middle of the hole.We also had tolerance on the burr which remained after drilling,  max. 0,05 mm, without manual touching. Never saw that before! We were even searching for a new lubricant on the milling machine and for a instrument to check the burr. We bought a beautiful machine with stylus to check the chamfer profile.

2008.

The largest machine at the time came to our shop:  Micron 1850, 5-axes Milling Center with 3 working tables up to 2 tons. For the first time we had a machine which was working without an operator in the night shift. Great achievement!

2007.

JPNO started  qualification for the new type of fuel integral nozzle (WIN) for pressurized water reactor (PWR) which needs 5-axes milling in order to achieve location tolerances for certain features. Lots of testing in optimising the order of operations and relations between rough and fine milling.

2006.

The first modern 4-axes milling center Heller required much learning on the part of CNC programers and operators to avoid collisions, in setting cutting tools and in monitoring the life of cutting tools in order to maintain the tolerances on the final product.

Also, the first Walter Helitronic Vision 5-axes grinding center for cutting tool production with Tool-Check enabled reverse engineering on cutting tool geometry.

2004.

TEH-CUT, the large machining shop for production of injection molding tools and stamping dies, was searching for a place in an everchanging market and for the implementation of modern CAD-CAM technology. First investment in Electrodischarging Machines (EDM) and CNC milling centers. A lot was learned about mould design, machining and assembly.

2002.

The TEH-CUT Company takes the opportunity to buy the Jedinstvo-PNO machining  company with its 50 employees. TEH-CUT moves to the premises of JPNO. TEH-CUT had been producing metal cutting tools since 1992, JPNO had been producing nozzles, stainless steel components, for nuclear fuel assemblies also for 10 years.
