GRINDING FEEDS AND SPEEDS

The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

ANCA

To reduce cycle time, it is better to reduce the number of passes than to increase feed-rates. However, if cycle time reduction is aimed for and one must choose between increasing the depth of cut or the feed-rate, it is better to increase the feed-rate as this makes the grinding …

5 Grinding Considerations for Improving Surface Finish ...

Mr. Maurer says peel grinding’s reduced grinding forces mean wheels require dressing less frequently. Wheels used for peel grinding carbide typically require dressing after 500 to 1,000 parts. That’s good, because dressing metal bond wheels even using the S41’s silicon carbide rotary dressing disc can take upwards of a day.

Fig. 1. High speed grinder for machining engineering ceramics. Resin bond diamond wheels of grit sizes of about 160 and 20 μm were used. The wheels have a diameter of 200 mm and a width of 6 mm. Before grinding, the wheels were balanced at 40 m/s using a dynamic balancing instrument (Sigma SB-7001). After balancing, the wheels were trued using ...

5 Grinding Considerations for Improving Surface Finish ...

Creepfeed/surface grinding: Increase wheel speed. This is a good starting point. However, be sure the wheel is rated to run at the new speed. The maximum operating speed (MOS) will be stated on the side of the wheel. Reduce feed rate. Reduce depth of cut. Increase the number of spark-out passes.

Experimental evaluation and surface integrity analysis of ...

When the wheel speed of the grinding process increased to 52.6 m/s, the surface quality seems to be better because the surface roughness decreased, …

Optimizing grinding and dressing with 'dressing speed ...

The dress speed ratio is the relationship between the dress roll velocity (V r ) in sfm or m/sec and the grinding wheel velocity (V s) in sfm or m/sec. and can be calculated using the following equation: Speed ratio = V r ÷ V s. The dress speed ratio can be a …

Choosing The Right Grinding Wheel | Modern Machine Shop

Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute. Working at higher speeds usually requires specially designed wheels for high speed grinding.

An Approach to Reduce Thermal Damages on Grinding of ...

The cutting parameters used in grinding experiments were grinding wheel speed (v s) of 37 m/s, workspeed (v w) of 3 m/min and radial depth of cut (a e) of 30 μm. The grinding process was performed using a cross-feed strategy, with a depth of cut (a p) of 0.9 mm as schematically shown in Figure 1. All the cutting parameters were kept constant ...

Experiences in the grinding of silicon nitride on a lower ...

One important consideration in high speed grinding of ceramics is to reduce the undesirable vibrations which can potentially cause strength degradation of the workpiece. A slightly unbalanced wheel at high spindle speed exerts high enough in-process impact energy on the workpiece to reduce the strength, although moderate process parameters

Grinding of Metals: Origin and Cutting Action | Industries ...

For normal grinding, temperature can be reduced by lowering wheel speed but not by decreasing chip thickness. In fact thermal damage can result for light finishing cuts. By using fluid in grinding, not only workpiece temperature decreases and wheel wear decreases, but wheel is less loaded which reduces frequency of wheel dressing.

The Powerful Potential of Peel Grinding

Basically, peel grinding uses a narrow grinding wheel, usually 0.25″ (6.4 mm) or less in width, to grind a part. Because the process is much like cutting with a conventional lathe, it is a major competitor to hard turning. The advantages of peel grinding include: Dramatically reduced cycle time. Combined operations. Decreased throughput time.

Ask The Grinding Doc: Decrease diameter, increase speed ...

That’ll help you maintain a fairly constant chip load during grinding. As the wheel diameter gets smaller, the grinding arc length gets smaller, meaning fewer grits are in the action. If you want to maintain exactly the same chip load, the equation is: new rpm = original rpm × (original diameter ÷ current diameter) 1.5 1.5] once it gets down to ...
