Customer story


˝DMU eVo‘s super stability enables us to machine titanium parts for the aerospace or medical industry with superior precision.˝

JK Engineering, founded in 2001, has its origins as a manufacturing service provider for Formula 1, where complex precision parts are all in a day‘s work. Based in Kings Langley, England, the company has also pursued this high demand into the Medical, Dental and Electronics industries and – since becoming AS 9100 and ISO 9001 certified – the Aerospace and Defense Industries as well. The backbone of JK Engineering‘s staff includes 25 skilled and dynamic experts. The technological base of the company is a modern shop consisting of 14 DMG MORI machining centers and lathes. A good share of this is taken up by 5-axis universal machines and automation.

˝We are operating in a fast-moving market with extremely high quality demands,˝ summarizes John Kenny, CEO of JK Engineering. His team has quickly learned that they must not just meet these typical market demands but they must exceed them as well. ˝We will only be able to remain competitive if we consistently expand our knowhow and invest in the most up-to-date machining technologies.˝ One result of this thinking was the introduction of 5-axis machining 7 years ago. ˝DMG MORI‘s DMU 50 was, in our opinion, the first truly reliable 5-axis machine,˝ recalls John Kenny, speaking of the purchase. In addition, the compact model with its small installation footprint fit perfectly into the production environment. ˝5-axis machining enabled us to significantly reduce the number of setups, which gave us a great advantage over our competition.˝ The competition was still manufacturing using 3-axis machines at that time.

Since then, JK Engineering has remained loyal to DMG MORI. Ten of the 14 models are from the DMG MORI mill using 5-axis technology: three DMU 50 units, five DMU 40 eVo units and two DMU 60 eVo units, the newest of which are equipped with pallet changers. John Kenny lists another critical feature of the machines: ˝Thanks to their stable construction and high-performance spindles, we are able to do extremely productive and precise work in the area of heavy-duty chipping.˝ Degrees of accuracy of 0.0004 in. are routine. ˝The temperature management of the DMG MORI machines also contributes to this precision.˝ The fact that JK Engineering manufactures are in air-conditioned rooms goes almost without saying.

5-axis machining was JK Engineering‘s first step toward sustainable process optimization. ˝Automation is the key to the most efficient possible use of this machine park,˝ says John Kenny knowingly. Robots and loading equipment are indispensable for unmanned production done overnight and on the weekends. ˝The robots give us additional flexibility in the area of small lots, because we can easily adjust the job priorities as needed without tedious setup times.˝ The automated tooling of the machines also eliminates imprecision introduced by manual chucking. John Kenny is optimistic about the future: ˝Our professional skill combined with the reliable and precise machines from DMG MORI will help us to deliver extremely challenging components quickly and at competitive prices in the future.˝

Customer story

˝Thanks to the DMU 80 eVo linear, we can now machine superalloys four times faster – and we‘re doing it at a precision of ± 0.00008 in.˝

After the collapse of Lehmann Brothers, Hidenobu Shigeki visited 30 potential customers a month because the company experienced a sharp drop in orders. Thanks to his marketing efforts, the company is larger and more successful than ever today.

˝Our company primarily manufactures prototype parts for air conditioners, vehicles and bicycles, and sometimes does it with delivery lead times of only two days,˝ explains Plant Manager Hidenobu Shigeki, referring to the typical challenges involved in prototype manufacturing. “With respect to precision, we allow no compromise, regardless of how short the delivery schedule is. Many orders specify a geometric precision of 7.9 in. These sometimes involve hard-to-cut materials such as Hastelloy.”

In order to ensure a high level of precision, Tomoei Seimitsu always checks all the temperature fluctuations on the machines and puts every workpiece through their quality control. ˝With every order, we accept the challenge to meet short delivery times while maintaining the highest possible precision part,˝ says Shigeki. In order to be able to meet the growing number of orders, Tomoei Seimitsu has invested in nine new machines in the plant during the past two years.

˝The DMU 80 eVo linear above all contributes significantly to increasing our productivity,˝ explains Hitoshi Nagao, Director of Production. He praises the performance of the DMU 80 eVo linear and says that ˝the machine‘s linear drive makes it four times more productive than machines from other manufacturers when machining 3D-open-die molds.˝ The DMU 80 eVo linear is far and away the favorite among the 5-axis machines in the plant. Every operator prefers to work on the eVo and ˝Grab the eVo whenever it‘s free˝ has become a byword on the production floor.

Production Director Nagao explains why this is the case, ˝The eVo is very easy to use, particularly when it‘s a matter of machining high precision workpieces just-in-time. The wide door to the workspace provides ideal accessibility and makes setup easy. Plant Manager Shigeki explains his hopes for the company‘s future from a management perspective: ˝DMG MORI machines have an incredibly small footprint and achieve extremely high productivity per unit area. We would like to continue expanding and to maintain our leadership position in the field of prototype manufacturing.˝
