Case-hardened steels - Import export

This material group comprises C-steel with low carbon content, good formability and fineblanking quality. Due to case hardening, the components have low-wear surface layers with high hardness and sufficient toughness in the core. They thus combine numerous properties and application possibilities in a wide variety of industries. To increase the wear resistance, you can also carburize or carbonitrate partial areas. C 10 E, C 15 E /➔ according to DIN EN 10132 - 2 Depending on the customer's requirements, we supply treatment states from soft annealed to high cold solidified.

In terms of precision, stability, and flexibility the vulcanized segmented clamping bushings are unbeatable. They consist of segments made of chrome/nickel, case hardened steel that is very hard, extremely wear resistant, and rigid [60 HRC]. Plus, they do not have to »bend« to clamp the workpiece. In addition, all functional surfaces are completely ground in one clamping set-up. The result: maximum run-out accuracy, maximum holding power, and long life span.

Extremely high clamping force Often complete machining fails for lack of an effective I.D. clamping device. In many cases the jaw chuck is a makeshift solution. However, even conventional mandrels with slotted clamping sleeves quickly reach their limits in terms of accuracy, rigidity, and opening stroke. HAINBUCH segmented mandrels use state-of-the-art clamping technology that is convincing, even in the most critical applications. Segmented clamping bushing with extremely hard, wear resistant and rigid segments The central element is the vulcanized segmented clamping bushing. Because conventional clamping bushings are made of spring steel and are only annealed to spring hardness, they are »soft« and they must »bend« to clamp the workpiece. HAINBUCH segmented bushings, on the other hand, are made of case-hardened chromium-nickel-steel and have segments that are extremely hard, wear resistant and rigid.

Whether lathe or machining center Complete machining made easy: You cannot only use our MANDO and MAXXOS segmented mandrels on the lathe, you can also use them in stationary mode. Simply screw the mandrel onto the ms dock [manually actuated] or hs dock [hydraulically actuated] and you can clamp your workpiece from the inside, stationary mode. Precise, without vibration and with minimum set-up effort. The extremely wear-resistant segmented clamping bushing of case-hardened chromium-nickel-steel with the rubber between the segments, especially developed by HAINBUCH, makes it possible. Hydraulic actuating unit hs dock hs dock is an absolute powerhouse that enables hydraulic implementation of MANDO and MAXXOS segmented mandrels on machining centers. Media supply can be freely selected. It is actuated either from the side or via a base plate from below. Perfect when automation is involved.

Manual actuating unit ms dock The hand-actuated ms dock in conjunction with stationary MANDO and MAXXOS segmented mandrels is ideal for machining centers, measuring machines, radial drill presses, parallel and angle plate clamping or for clamping on dividing heads. The version ms dock rotating can be used on turning and grinding machines until RPM 1/min.

Bush conveyor chains are often used for conveying tasksinvolving long transport distances at relatively low speeds. Since only a small minority of chains used in the industry are totally compliant with one specific standard, ELITE conveyor chains are custom-made to a specific customer order and consequently fulfil a large number of special requirements. ELITE highlights: • Pins usually made of heat-treated alloy steel, inductionhardened • Bushes made from seamless precision steel tube, case-hardened • Link plates made of high-strength tempered steel or case-hardened steel alloy • Rollers (where present) made of case-hardened steel, case-hardened

CBN (cubic boron nitride) is the next hardest material after diamonds. When properly used, tools made from CBN exhibit considerably less wear than other materials. Cutting inserts or even VHM tools can be equipped with CBN. Technical application: Hardened tool steels with hardnesses greater than 55 HRC or high speed steels (HSS) can be machined without problems using CBN. Case hardened steels and chilled cast iron can also be machined with CBN. Non-ferrous metals are totally unsuitable for CBN; diamond tools are needed for these.
