Precision Guidance Needed for Metalworking Machinery That
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. -
Types of Tap
Types of Tap HAND TAPS ISO 529 These are straight flute general purpose tools which can be used for both machine or hand tapping. They are generally the most economical tool for use on production runs, but are best on materials that produce chips, or where the swarf breaks readily. Where deep holes are to be tapped, in materials which produce stringy swarf, serial taps may be needed, especially for coarse threads. ISO 529 hand taps can be supplied in sets of three; bottom, second and taper leads, or individually. BOTTOM TAPS have a chamfer (lead) of 1–2 threads, the angle of the lead being around 18 degrees per side. They are used to produce threads close to the bottom of blind holes. SECOND TAPS have a lead of 3-5 threads at 8 degrees per side. They are the most popular and can be used for through holes, or blind holes where the thread does not need to go right to the bottom. TAPER TAPS have a lead of 7-10 threads at 5 degrees per side. The taper lead distributes the cutting force over a large area, and the taper shape helps the thread to start. They can therefore be used to start a thread prior to use of second or bottom leads, or for through holes. IMPORTANT NOTE ON TERMINOLOGY! In the U.K. bottom taps are often referred to as ‘plugs’. In North America second taps are often referred to as ‘plugs’! This can easily lead to confusion. To avoid problems when ordering it is best to use the terms bottom, second and taper. -

Utilization of Waste by Preparing the Product from Swarf Forging of Alloy
et International Journal on Emerging Technologies 6(2): 181-183(2015) ISSN No. (Print) : 0975-8364 ISSN No. (Online) : 2249-3255 Utilization of Waste by Preparing the Product from Swarf Forging of Alloy Steel (16MNCR5) Abid Nazir and Harvinder Lal Department of Mechanical Engineering, RIET, Phagwara, (PB), India (Corresponding author: Abid Nazir) (Received 01 October, 2015 Accepted 06 November 2015) (Published by Research Trend, Website: www.researchtrend.net) ABSTRACT: The aim of thesis is to prepare the product from swarf forging of alloy steel (16MnCr5). This thesis is an example of how the waste fraction can be transferred from waste to a resource that can be used in other industrial processes. It offers both environmental and economic benefits. Swarf forging gives better control, environmental credits, cost savings an increased margins. Swarf collected from lathe, milling, drill or any other cutting machine is cleaned by degreasing, pickling and acid pickling. Preliminary heat treatment is done to eliminate the work hardening, moisture content and impurity content. Swarf can be continuous, discontinuous or powder form. After collection of swarf, put in mild steel tube for compression. Compression of swarf is done by hydraulic press. The force is applied on piston which is inserted in tube. After compression, swarf which is in form of cylinder is taken out. After this heat the samples are heated and forged with the help of manual hammers or with help of hydraulic hammer. After forging hardness, density and microstructure are checked. The values indicate that product made by swarf forging can be used for low load application like door handles, hangers etc. -

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. -
