Double-disc grinding has always offered a highly productive and accurate means for machining to-size parts with flat and parallel sides. In this grinding method, two opposed abrasive discs, each mounted on its own spindle, simultaneously grind opposite and parallel faces on workpieces traversed between them via any of several fixturing/carrier techniques.

Peel grinding machines offer a modern approach that achieves flexible grinding operations of a variety of diameters, grooves, thrust faces and forms using one set-up. Peel grinding is often compared with hard turning where a tool is traversed along a hardened workpiece following an appropriate form. Peel grinding operates in a similar mode removing a narrow strip of material as the grinding ...
Feb 16, 2011· Special types of grinders are grinding machines made for specific types of work and operations, for example: Tool and cutter grinders. These grinding machines are designed to sharpen milling cutters, reamers, taps and other machine tool cutters. The general-purpose cutter grinder is the most popular and versatile tool-grinding machine.
Cost often is a deciding factor when you purchase a grinder. However, the saying you get what you pay for can be true when you're talking about tools. The price tag alone doesn't always reflect some of the more important factors--performance level, cost to operate, and tool life--that make a grinder …
Instead of grinding a lobe shape in the workpiece, the high spot is gradually reduced by the action of the grinding wheel. So rather than creating a low spot on the periphery of the work equal to the high spot, the grinding wheel generates a proportionally smaller low spot at its contact with the workpiece.
and sub-surface damage from heat generated during grinding. Even with "Low Stress" grinding the conventional abrasives will not impart the compressive residual stress that is found when grinding with CBN. Note: Low Stress grinding is a process where the grinding wheel is a friable abrasive

Examples of limit charts derived for plunge feed centerless grinding are illustrated in Figures 5.24 and 5.25.Removal rate is proportional to infeed rate, v f, in plunge centerless grinding.For the particular conditions, the optimum workspeed is seen to be given approximately by v w = 0.25 m/s, when grinding with medium carbon steel, AISI 1055, or with gray cast iron.
SMART CUT™ LP is a Variable Speed Precision Polishing, Grinding, Lapping Machine. Designed for Mechanical Sample Preparation. SMART CUT™ LP Provides equal Precision, Productivity and Versatility as High Cost Fully Automatic Grinding/Polishing Machines, at a small fraction of the price. Compare to Brand Name Grinding / Polishing Machines for Sample Preparation & Materials Research.
Cutting speed. Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
The phrase speeds and feeds or feeds and speeds refers to two separate velocities in machine tool practice, cutting speed and feed rate.They are often considered as a pair because of their combined effect on the cutting process. Each, however, can also be considered and analyzed in its own right.

How to Use a Surface Grinder Machine: A surface grinding machine is used to produce a smooth accurate finish on either metallic or nonmetallic materials. It uses a round rotating abrasive grinding wheel that remains stationary (but rotating) while the feed table (with work attached) is run in a reciprocating motion (left and right) under the ...
Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
Apr 11, 2017· The centerless process is commonly used for high volume production, and it's also easily used for low volume production because the machine setups are fairly simple. In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right).
Grinding Wheel Speed Calculator: All Norton grinding wheels are marked with a maximum operating speed in RPM. Most machines, and especially CNC machines, use Surface Feet Per Minute (SFPM) as an input, which requires operators to do the conversion.
In the equation of Time for Cylindrical Grinding Cut Length of Cut = Length of job + Over-Travel where, Over-Travel equals to 0.5 cm. And Feed/Rev. = w/2 (for rough cut) or w/4 (for finishing cut).
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. On the other hand, very low grinding wheel speeds, in the order of 3,000 to 4,000 fpm (about 15 to 20 m/sec) are needed ...
Chapter 3: Grinding Geometry and Kinematics 3.1 INTRODUCTION Material removal by grinding occurs mainly by a chip formation process, similar to that of other machining methods such as turning or milling, but on a much finer scale.
Pros - Great price. This grinder came with Aluminum Oxide (white) wheels (60 and 120 grit), which are SO far superior to the gray silicon carbide wheels that comes on many grinders - it's really the most important upgrade that can be made to ANY grinder.
Belt grinding machines remove a pre-defined quantity of material per work cycle, which makes it easy to maintain dimensional accuracy by spreading the abrasion process across different work cycles with varying grinding heights. Belt grinding machines are also designed to be simple and are thus easy to …
