As increasingly stringent carbon emissions regulations are being imposed on the automotive industry, one solution to ensure compliance with these regulations is with variable engine timing using cam pieces. The JUCAM 1S from JUNKER specializes in the ultraprecise, efficient grinding of cam pieces.
The nerve center of the JUCAM 1S is a double workhead with two clamping fixtures. It can be swiveled 180 degrees to a precisely defined end position. The workpiece transfers from its initial loading position to the grinding position using a fully automated process. Concurrently, the second workpiece transitions from the grinding to the discharge position, which drastically reduces downtime.
JUNKER says its JUCAM 1S enables automotive manufacturers and suppliers to achieve economical cam piece grinding. The JUNKER noncylindrical grinding machine also specializes in the efficient package grinding of single cams.
When grinding cam pieces, the precise angular reference to the inner toothing is essential. Accordingly, the JUCAM 1S clamps the cam pieces with an inner clamping mandrel. The high quality standards demanded by the automotive industry are fulfilled by the "cam piece specialist” with its intelligent control system. This compensates automatically for material deviations or disturbing variables, such as fluctuations in temperature, guaranteeing that all components conform to a constant standard.
CBN, in a range of specifications, is used as an abrasive for maximum repeat accuracy, extended service life and high stock removal performance coupled with a consistently high standard of quality. Depending on the application, the grinding wheels are comprised of a carbon base body: It is lightweight, possesses vibration-damping properties and remains dimensionally stable even at high speeds.
With its JUCAM 1S, JUNKER offers far more than just a grinding machine. The company’s performance promise includes delivery and installation of the machine, as well as a fully customized grinding process to meet the customer's production requirements.

abrasive
Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.
- computer-aided manufacturing ( CAM)
computer-aided manufacturing ( CAM)
Use of computers to control machining and manufacturing processes.
- cubic boron nitride ( CBN)
cubic boron nitride ( CBN)
Crystal manufactured from boron nitride under high pressure and temperature. Used to cut hard-to-machine ferrous and nickel-base materials up to 70 HRC. Second hardest material after diamond. See superabrasive tools.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding machine
grinding machine
Powers a grinding wheel or other abrasive tool for the purpose of removing metal and finishing workpieces to close tolerances. Provides smooth, square, parallel and accurate workpiece surfaces. When ultrasmooth surfaces and finishes on the order of microns are required, lapping and honing machines (precision grinders that run abrasives with extremely fine, uniform grits) are used. In its “finishing” role, the grinder is perhaps the most widely used machine tool. Various styles are available: bench and pedestal grinders for sharpening lathe bits and drills; surface grinders for producing square, parallel, smooth and accurate parts; cylindrical and centerless grinders; center-hole grinders; form grinders; facemill and endmill grinders; gear-cutting grinders; jig grinders; abrasive belt (backstand, swing-frame, belt-roll) grinders; tool and cutter grinders for sharpening and resharpening cutting tools; carbide grinders; hand-held die grinders; and abrasive cutoff saws.
- mandrel
mandrel
Workholder for turning that fits inside hollow workpieces. Types available include expanding, pin and threaded.
