Product Information

Having done a LOT of grinding over my lifetime with close to 60 years of workshop experience, I would like to comment on some of the material presented. Some of it I totally disagree with. Breaking it down we need to divide grinding into either off hand or precision. Off hand is where either the workpiece is held by hand or the grinder is hand held. Lathe tools, chisels, drill bits etc can be ground on off hand machines. Then with precision grinders they can be Cylindrical (plunge, plunge and wipe or traverse), Internal (dedicated or universal in either plain or auto size versions eg. Heald Sizematic. ) Next comes Surface Grinders with different table/spindle configurations (horizontal spindle / horizontal reciprocating table, vertical spindle / horizontal reciprocating table, horizontal spindle / revolving circular table, vertical spindle / revolving circular table with either solid grinding wheels or in the case of vertical spindle machines they also may have segmented wheels that are screwed in to form a wheel head. Next we look at centreless grinding machines that use 2 wheels consisting of a grinding wheel and a regulating or ‘control’ wheel. These wheels generally have a wide face and the operations are either plunge or through grinding. The tilt on the regulating wheel determines the speed of the workpiece past the grinding wheel. Next we have Tool and Cutter Grinders which can also be used to do surface and cylindrical work if the attachments are available. There is another type of grinding that fits in between off hand and precision and it is called ‘Spot Grinding’. Spot Grinding is a scary operation that you thank providence that you still have your fingers after you finish. It is used where the workpiece is too small to grip it by magnets or it is small and non ferrous (hence non magnetic). I have used all of these machines and methods and still remember the 6 monthly periods where the largest tolerance I saw was 0.0001″ .

Grinding is a widely used abrasive finishing process. Did you know grinding machines have been around for centuries? Well, not the electric ones but the ones that are powered via a pedal. Milling practice is a large and diverse area of manufacturing and toolmaking. It can produce very fine finishes and very accurate dimensions; yet in mass production contexts, it can also rough out large volumes of metal quite rapidly. It is usually better suited to the machining of very hard materials than is "regular" machining (that is, cutting larger chips with cutting tools such as tool bits or milling cutters), and until recent decades it was the only practical way to machine such materials as hardened steels. Compared to "regular" machining, it is usually better suited to taking very shallow cuts, such as reducing a shaft's diameter by half a thousandth of an inch or 12.7 μm.Electrolytic in-process dressing ( ELID) grinding is one of the most accurate grinding methods. In this ultra precision grinding technology the grinding wheel is dressed electrochemically and in-process to maintain the accuracy of the grinding. An ELID cell consists of a metal bonded grinding wheel, a cathode electrode, a pulsed DC power supply and electrolyte. The wheel is connected to the positive terminal of the DC power supply through a carbon brush whereas the electrode is connected to the negative pole of the power supply. Usually alkaline liquids are used as both electrolytes and coolant for grinding. A nozzle is used to inject the electrolyte into the gap between wheel and electrode. The gap is usually maintained to be approximately 0.1mm to 0.3mm. During the grinding operation one side of the wheel takes part in the grinding operation whereas the other side of the wheel is being dressed by electrochemical reaction. The dissolution of the metallic bond material is caused by the dressing which in turns results continuous protrusion of new sharp grits.

The final shape of a workpiece is the mirror image of the grinding wheel, with cylindrical wheels creating cylindrical pieces and formed wheels creating formed pieces. Typical sizes on workpieces range from 0.75in to 20in (18mm to 1m) and 0.80in to 75in (2cm to 4m) in length, although pieces from 0.25in to 60in (6mm to 1.5m) in diameter and 0.30in to 100in (8mm to 2.5m) in length can be ground. Resulting shapes can be straight cylinders, straight-edged conical shapes, or even crankshafts for engines that experience relatively low torque. During the grinding process, the abrasive is applied to the surface of the grinding tool, and the grinding material rolls or slides between the grinding tool and the workpiece, forming a cutting effect on the surface of the workpiece. The processing efficiency is high, but the geometric shape and dimensional accuracy, and gloss of the processed surface are not as good as dry grinding. It is mostly used for rough grinding and semi-finishing of flat surfaces and inner and outer cylindrical surfaces. Oftentimes grinding operations are compartmentalized by machinists and considered separate from typical cutting processes used in machine shops. This is most likely for a couple reasons, one being that grinding operations are quite often mistaken as a rubbing process and not a cutting one. Also, grinding is a cutting process that actually creates a smooth finish, unlike the other processes in the category that create unsmooth surfaces. Prathikanti S, et al. (2017).

This unfortunately doesn’t mean that they do not break.We have covered the basics when it comes to this problem and we explained how to read this audible information. So, if you notice a grinding noise when turning, you need to focus more on the suspension components and see which of them is going bad. Then we have learned the probable reasons why you are hearing this noise. Considering that it only happens when you are turning. You are highly likely experiencing this noise because some of the suspension components are bad and need replacing. More precisely the CV axle, the bushings of the control arm, pads and rotors, and wheel bearings. Matthew, Sam (2016-12-17). "The basics of abrasive cutting". tungstengrinder.net .
