    Precision guidance needed for metalworking machinery that automatically grinds 40,000 sinks every year https://www.hepcomotion.com/case-studies/precision-guidance-needed-for-metalworking-machinery-that- automatically-grinds-40000-sinks-every-year/ INDUSTRY PRODUCT COUNTRY PROCESS GV3 - V Linear Manufacturing Germany Grinding Guide System Peitzmeier Maschinenbau machine builders based in Germany specialise in the construction of grinding machines. Their latest invention, the Omni-Grind Twin 3100 AC, enables automated grinding and polishing of workpieces in the metalworking industry. The machine builder relies on HepcoMotion’s GV3 guidance to prevent damage to the steel during processing; the linear guide system enables precise alignment of the grinding tool in the range of hundredths of a millimetre. The challenge: A major customer wants to precision grind 40,000 stainless steel sinks per year Among the users of Peitzmeier’s grinding machines is a Dutch manufacturer, who processes stainless steel sinks for a Swiss company. The design of the grinding machine had some challenging requirements, as Ulrich Peitzmeier, Managing Director of Peitzmeier explains: “The three-ton plant needed to be capable of grinding 40,000 sinks per year with extra care – the sinks are made from sheet metal just one millimetre thick. If a tool takes too long grinding material in one place, it can very quickly damage the workpiece.” Peitzmeier had to adapt their grinding machine to meet these requirements. The heavy grinding tool, usually mounted on a double-stranded U-rail, had to be replaced in favour of a lighter tool that could be aligned more precisely on just a single guide rail.

  • Grinding Machine Construction Types of Grinders
    Grinding machine A grinding machine is a machine tool used for producing very fine finishes or making very light cuts, using an abrasive wheel as the cutting device. This wheel can be made up of various sizes and types of stones, diamonds or of inorganic materials. For machines used to reduce particle size in materials processing see grinding. Construction The grinding machine consists of a power driven grinding wheel spinning at the required speed (which is determined by the wheel’s diameter and manufacturer’s rating, usually by a formula) and a bed with a fixture to guide and hold the work-piece. The grinding head can be controlled to travel across a fixed work piece or the workpiece can be moved whilst the grind head stays in a fixed position. Very fine control of the grinding head or tables position is possible using a vernier calibrated hand wheel, or using the features of NC or CNC controls. Grinding machines remove material from the workpiece by abrasion, which can generate substantial amounts of heat; they therefore incorporate a coolant to cool the workpiece so that it does not overheat and go outside its tolerance. The coolant also benefits the machinist as the heat generated may cause burns in some cases. In very high-precision grinding machines (most cylindrical and surface grinders) the final grinding stages are usually set up so that they remove about 2/10000mm (less than 1/100000 in) per pass - this generates so little heat that even with no coolant, the temperature rise is negligible. Types of grinders These machines include the Belt grinder, which is usually used as a machining method to process metals and other materials, with the aid of coated abrasives.

  • Design and Fabrication of Internal Grainding Attachment in Lathe
    Vol-6 Issue-1 2020 IJARIIE-ISSN(O)-2395-4396 DESIGN AND FABRICATION OF INTERNAL GRAINDING ATTACHMENT IN LATHE PRESENTED BY AGASH.P ME (CAD) LECTURER DEPARTMENT OF MECHANICAL ENGINEERING (TOOL&DIE) A.K.T MEMORIAL POLYTECHNIC COLLEGE, KALLAKURICHI ABSTRACT Everyone knows a tool post grinder is one mighty handy item to have as an addition to a lathe, however, if you ever priced one, you know they run in to some serious amounts of money. So, with this in mind, I set off to build my own. Pictured below is the outcome of that project. I have to say the tool post grinder works extremely well. By varying the pulley sizes I can get a high end speed of over 10,000 rpm if needed. The only change I would make is to have a totally enclosed motor to keep out the grit. Our project is design and fabrication of Multi Use Tool Post Grinder. It is used to grind the machining surfaces to super finish and accuracy. It can be used as an internal and external Grinder by fixing the attachment on the Carriage of a center Lathe. The principle parts of this attachment are main body, Spindle shaft, bearings, rope pulley and grinding wheel etc. Keywords: design, 2d diagram cad, grinding attachment 1. INTRODUCTION Generally some components in engineering field require high surface finish and accuracy. For example a cylindrical part requires high finish inside the bore or outside the body; it requires cylindrical grinding machine and center less grind machine. The above machinery cost will be more, and also unless we have lot of similar jobs, we equity keep these costly machines idle.

  • Hobbing and Grinding Process Modelling of Helical Wheel in the Speed Reducer of an Electric Vehicle
    Hobbing and Grinding Process Modelling of Helical Wheel in The Speed Reducer of an Electric Vehicle Master's Thesis in Mechanical Engineering Supervisors: Jérôme BRUYERE François GIRARDIN Tutor: Francesca Maria CURÀ Grad student: Nagelaa ES SAFIANI 2 MASTER'S THESIS IN MECHANICAL ENGINEERING Hobbing and Grinding Process Modelling of Helical Wheel in The Speed Reducer of an Electric Vehicle Nagelaa ES SAFIANI Department of Mechanical Engineering Division of Industrialization and Processes National Institute of Applied Sciences of Lyon Lyon, France 2019 Department of Mechanical Engineering Division of Production Polytechnic University of Turin Turin, Italy 2019 3 Abstract When developing a mechanical transmission one important characteristic of the transmission is how much tonal noise and vibrations are generated. The vibrations causing are called gear whine noise and they are generated in the gear contacts of the transmission and propagate through the shafts and bearings to the housing, where they become airborne. In electrical vehicle applications the absence of a loud combustion engine makes the gear whine noise more distinct and easily perceived by the human ear. The main cause of the noise has been assumed to be excitations due to variations of tooth profile errors in the wheel of speed reducer. For this reason, a code to simulate the hobbing and grinding process, that generates the helical wheel, has been developed by the MATLAB software. To write the code, a kinematic study about hobbing and grinding process has been performed, then it has been possible to obtain the theoretical points of contact on wheel surface and hob surface. After obtaining the programming code, it will be possible to compare the theoretical and real surfaces and analyse the possible causes.
