  • Instructions for Using the OMW Sensitive Tapping Kit
    Thank you for purchasing the OMW Sensitive Tapping Kit. I hope you enjoy using it as much as I enjoyed making it. With a little care, this tool should give you many years of service. Please read the instructions below to take full advantage of your new Tapping Kit. And let me know if you have comments or questions. I can be reached via email at [email protected], or at OMW Corporation (21 Pamaron Way, Ste. G., Novato, CA 94949). Best Regards, Joe Osborn President, OMW Corporation. Instructions for Using the OMW Sensitive Tapping Kit Background The OMW Sensitive Tapping Kit was inspired by my efforts to tap very small holes in soft material, such as brass and plastic. I found standard tapping wrenches to be far too large and lacking in the sensitive “feel” needed to keep from stripping the hole. Initially, I actually wrapped tape around the tap itself and turned the tap between my fingers. Searching for a better technique led to my design The OMW Sensitive Tapping Wrench of the Sensitive Tapping Kit. I hope that you will enjoy it. Using the Sensitive Tapping Kit Tap Guide Tap Extension Wrench Guide Rod The Sensitive Tapping Kit is composed of four parts. The Wrench, which is used to hold the taps; the Tap Guide, which is used to hold the tap straight to the hole; the Tap Extension, which extends the reach of the Wrench; and the Wrench Guide Rod, which allows the Wrench to be held straight in a lathe, mill or drill press. (OVER) 2 The Wrench and Guide Rod The Wrench will hold standard taps from 0-80 to 6-32, which all have the same shank diameter.

    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.

  • Tap Operating Guidelines
    Taps OPERATING GUIDELINES Understanding Taps • Optimize Tap Performance • Prevent Breakage Taps are rotary cutting tools that cut internal threads in metal. They have cutting teeth and either helical or straight flutes for the passage of chips and the admission of cutting fluid. The purpose of cutting internal threads is so that it can receive a part with an external thread, such as a bolt, rod, or fastener. These two parts can then be joined together. Taps can be made out of different types of steel and can be engineered for different applications (See Champion Tap Guide). Anatomy & Nomenclature The SHANK fits into the tap holder. The at the end of the tap, drives The FLUTES are grooves that provide SQUARE a path for the removal of chips and rotates the tap. FLATS are the sides of the square at the end of the shank and the flow of cutting fluid The POINT controls the ejection of chips* *Spiral Point Taps AKA “Gun Taps” are ideal for through hole applications The NECK enables the flow of The CHAMFER aligns the tap lubricant and deeper tapping and provides easy-starting Chamfer Styles > The chamfer is ground on the front of the tap to help it begin threading and assist with alignment. 7-10 TAPER - 7 TO 10 THREADS OF CHAMFER Nickname: “STARTER Taps” - they are easy to align and start threading 3-5 PLUG - 3 TO 5 THREADS OF CHAMFER Most popular - often used to start and finish threading in a single pass 1-1.5 BOTTOM - 1 TO 1.5 THREADS OF CHAMFER Nickname: “FINISHING Taps” - can thread to the bottom of a blind hole (packs the chips at the bottom) Through Holes vs.
