Through HWR\u2019s INOFlex and INOZet clamping solutions, EMB Zerspanungstechnik further enhanced its ability to meet customers\u2019 quality demands.<\/strong><\/p>\r\n\r\n\r\n\r\n

EMB Zerspanungstechnik (translated, EMB Machining Technology) was founded in Beidenkopf, Germany in 1955. The area, including nearby Lahntal, was well known for its foundries, and EMB started as a foundry producing hearth and furnace castings.<\/p>\r\n

Currently in its third generation of leadership, the company is headed by managing partner Michael Runkel and employs 17 people. In 1973, EMB transitioned from foundry to machine shop, and it acquired its first CNC machine in 1986. Today, it operates twelve CNC machines for turning and milling.<\/p>\r\n

Most commonly, EMB machines parts from spheroidal castings of grey cast iron. The company also manufactures parts from both aluminum and stainless steel, predominantly 1.4305.<\/p>\r\n

\u201cMost of our customers are foundries and engine plants, along with others from agricultural technology, bearing technology and the fitness industry\u201d, says Mr. Runkel of EMB\u2019s customer base.<\/p>\r\n

Approximately 80% of the components produced by EMB are turned parts, ranging from 20 mm to 300 mm in diameter and weighing up to 14 kg. Lot sizes can run from 200 to 30,000 pieces. The company has noted a significant increase in the demand for milled features in recent year, leading it to adopt CNC turn mills with 5-axis machining capabilities. EMB also provides customers with subassembly mounting.<\/p>\r\n

\u201cIn our assembly department, we assemble, for instance, some 50,000 sub-assemblies each year for a major customer,\u201d explains Mr. Runkel. \u201cThese, as completely picked & packed merchandise, are supplied with all accessories directly to the customers.\u201d<\/p>\r\n

EMB first started using HWR products in 2015, when it purchased the INO<\/strong>Flex\u00ae<\/sup><\/span> compensating, four-jaw chuck. This compensating chuck provides centric clamping of round, rectangular and irregularly shaped workpieces.<\/p>\r\n

\u201cWe had received an inquiry from a customer on machining aluminum components,\u201d says Mr. Runkel. \u201cOne of these components recalled to mind an advertisement from HWR for the INO<\/strong>Flex\u00ae<\/sup><\/span> chuck. After a thorough examination, we decided to opt for this chuck as it promised ease in clamping the component.\u201d<\/p>\r\n

EMB uses the INO<\/strong>Flex\u00ae<\/sup><\/span> chuck on an INDEX G200 CNC turn mill. Currently, two parts that are nearly identical in design are being produced on the machine.<\/p>\r\n

\u201cThe parts are components for supporting arm systems,\u201d says Mr. Runkel. \u201cThe INO<\/strong>Flex\u00ae<\/sup><\/span> is the ideal clamping solution since the parts have two straight and two semi-circular surfaces. The part could not be properly clamped in a three-jaw chuck.\u201d<\/p>\r\n

Optimal clamping is of vital importance, as they are zinc die-cast parts with extremely high tolerances. EMB finds exceptional value in INO<\/strong>Flex\u00ae<\/sup><\/span>\u2019s ability to center parts correctly at all times.<\/p>\r\n

Dennis Richter from HWR\u2019s Technical Sales team has worked with EMB since 2016, having been assigned to the company\u2019s region at that time. He consulted with the company when one of its customers requested production of a high-precision component requiring cylindricity within a tolerance of 6 microns. Reviewing the part drawing together, Mr. Richter and Mr. Runkel agreed that the HWR INO<\/strong>Zet\u00ae<\/sup><\/span> clamping system was likely the best solution.<\/p>\r\n

INO<\/strong>Zet\u00ae<\/sup><\/span> pendulum bridges allow traditional 3-jaw chucks to be quickly and easily converted into compensating 6-jaw chucks. The increased points of contact prove a tremendous advantage when machining thin-walled components.<\/p>\r\n

\u201cWe had to look into whether these specific tolerances could be held by the INO<\/strong>Zet\u00ae<\/sup><\/span> system,\u201d says Mr. Richter. \u201cIt is difficult to guarantee a cylindricity of six microns, but we believed it could be done and proceeded with testing the solution.\u201d<\/p>\r\n

It quickly became apparent that the system was capable of producing the part to the required specifications.<\/p>\r\n

\u201cSet up. Part manufactured. Part finished,\u201d recalls Mr. Runkel. \u201cIt was quick and simple, as was intended. The INO<\/strong>Zet\u00ae<\/sup><\/span> is a great product and functions perfectly.\u201d<\/p>\r\n

Today, when EMB encounters jobs with thin-walled parts that are experiencing deformation with a 3-jaw chuck, it quickly employs INO<\/strong>Zet\u00ae<\/sup><\/span>. The system\u2019s advanced capabilities have allowed the company to meet increasingly stringent demands from customers, while retaining flexibility and profitability.<\/p>\r\n","protected":false},"featured_media":6010,"template":"","product-category":[8],"acf":[],"_links":{"self":[{"href":"https:\/\/hwr-usa.com\/wp-json\/wp\/v2\/success-story\/3647"}],"collection":[{"href":"https:\/\/hwr-usa.com\/wp-json\/wp\/v2\/success-story"}],"about":[{"href":"https:\/\/hwr-usa.com\/wp-json\/wp\/v2\/types\/success-story"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/hwr-usa.com\/wp-json\/wp\/v2\/media\/6010"}],"wp:attachment":[{"href":"https:\/\/hwr-usa.com\/wp-json\/wp\/v2\/media?parent=3647"}],"wp:term":[{"taxonomy":"product-category","embeddable":true,"href":"https:\/\/hwr-usa.com\/wp-json\/wp\/v2\/product-category?post=3647"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
