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. -

Pavement Problems Addressed • Faulting at joints and cracks • Built-in or construction roughness • Polished concrete surface • Wheel-path rutting • Permanent upward slab warping and curling • Inadequate transverse slope • Unacceptable noise level Safety, Surface Texture and Friction • Increased macrotexture of diamond ground pavement surface provides for improved drainage of water at tire- pavement interface • Longitudinal -
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. -

Module 7 Screw threads and Gear Manufacturing Methods Version 2 ME, IIT Kharagpur Lesson 31 Production of screw threads by Machining, Rolling and Grinding Version 2 ME, IIT Kharagpur Instructional objectives At the end of this lesson, the students will be able to; (i) Identify the general applications of various objects having screw threads (ii) Classify the different types of screw threads (iii) State the possible methods of producing screw threads and their characteristics. (iv) Visualise and describe various methods of producing screw threads by; (a) Machining (b) Rolling (c) Grinding (i) General Applications Of Screw Threads The general applications of various objects having screw threads are : • fastening : screws, nut-bolts and studs having screw threads are used for temporarily fixing one part on to another part • joining : e.g., co-axial joining of rods, tubes etc. by external and internal screw threads at their ends or separate adapters • clamping : strongly holding an object by a threaded rod, e.g., in c-clamps, vices, tailstock on lathe bed etc. • controlled linear movement : e.g., travel of slides (tailstock barrel, compound slide, cross slide etc.) and work tables in milling machine, shaping machine, cnc machine tools and so on. • transmission of motion and power : e.g., lead screws of machine tools • converting rotary motion to translation : rotation of the screw causing linear travel of the nut, which have wide use in machine tool kinematic systems • position control in instruments : e.g., screws enabling precision movement of the work table in microscopes etc. • precision measurement of length : e.g., the threaded spindle of micrometers and so on. -
