zqm medium speed grinding parameter

The optimum parameters are as follows: particle size (S) = #1200, rotational speed (Wt) = 4500 rpm, cutting depth (Ap) = 0.25 mm and feed speed (Vf) = 0.8 mm/min. The roughness of the surface polishing with optimum parameters is reduced to 0.021 μm

The input parameters considered are: wheel is preferred for higher MRR and Al2 O3 grinding wheel speed, work speed, number of passes and depth of wheel for better surface finish. The increase in material cut and the responses are metal removal rate (MRR) and removal rate surface finish goes down

In this present work, the effect of input parameters viz. grinding wheel speed, work-piece speed, abrasive grain size, depth of cut, concentration of cutting fluid, and number of passes has been found on the out-of-roundness of cylindrical grinded AISI 4140 steel. Out-of-roundness is of great importance in case of shafts, axles, pistons, piston pins, crankshafts, roller bearings as out of

Feb 26, 2014 · For milling speed, since previous works usually used high speed ball milling which is more than 100 rpm, the best speed for low speed ball mill is unknown. Since higher speed results in higher collision between grinding balls and powder [ 7 ], the three highest speeds of the ball mill will be used which are 100 rpm, 95 rpm, and 90 rpm

Dec 23, 2018 · Grinding machine operates at high speed similarly other machine tools but the difference in the operation. The grinding machine used for finishing only after the machining done by some other machine tools. We can say that the function of the grinding machine comes into play after the machining of a work piece by turning or milling machines

Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm

Jul 15, 2016 · Surface quality of medium density fiberboard (MDF), as a very important criterion for further finishing and utilization, was evaluated using a wide range of measuring parameters (instruments, filters, filtering cut-off length, measuring length, measuring resolution, roughness parameters). However, these various approaches make any data comparison rather difficult. Furthermore, filtering the

Nov 25, 2008 · An experimental study was undertaken to investigate the role of process parameters on the grindability of medium carbon steel in a high-speed grinding domain with particular emphasis on surface integrity. Surface residual stress on the ground specimens has been assessed using X-ray diffraction technique and Barkhausen noise analysis

Jan 28, 2020 · As an additional process evaluation parameter, the wheel wear in grinding processes and especially the capability of monitoring systems to online measure the wheel wear turned out to be of

May 30, 2018 · The optimum conditions of grinding parameters for lower surface roughness for EN8 steel were the grinding wheel speed 1400 r.p.m., table travel speed 10 m min −1, depth of cut 10 µm, grinding wheel A60K5V10 and table cross feed 0.03 m min −1 for surface grinding
