Thru-feed grinding is the most efficient method known for high production surface grinding of small to mid size parts because it practically eliminates non-productive time. With the Thru-Feed Grinder, all machine time is grinding time, little is lost on fix-turing and preparation such as set-up, and loading and unloading of parts.
Thru-feed grinding is a type of centerless grinding. During this process, the workpiece passes through the machine itself. It proves to be an effective option for single-size diameter parts anywhere from a small dowel pin to a 16” shaft.
Putting the “Feed” in Zero-Defect Through-Feed Grinding Due to the nature of the parts, rotating them within a laser beam to check for out-of-round geometry was not an option. Instead, the cell employs a device designed for extrusion lines that derives ovality from three distinct diameter measurements taken with three intersecting laser beams.

With increased angle, quicker rounding occurs, but it also weakens the blade rigidity. The most common top angle used in centerless grinding is 30 degrees. As the diagram below indi es, lower angles are used when grinding heavy workpieces, which help minimize vibration. Workrest top angles typically range from 45 degrees down to 20 degrees.
Throughfeed Grinding. Throughfeed grinding also known as thrufeed grinding is the process of feeding the part through the regulating wheel and the grinding wheel. Throughfeed grinding is used for simple cylindrical parts. The regulating wheel is angled to the grinding wheel, with the inlet side having a larger opening.
Through-feed grinding is a form of centerless grinding in which the work piece passes through the machine. This type of grinding is effective for single diameter parts from small dowel pins to shafts up to 16” long. Sturdy Grinding has the ability to automate some thru-feed operations with vibratory bowls allowing for continuous feeding.
Most times, through-feed grinding is the ideal option for machines in the aerospace, automotive, defense and medical industries, but in-feed grinding is another method. At Sturdy Grinding in New Haven, MI, we use through-feed grinding techniques to provide high-quality products and increased productivity for your company.
Through-feed grinding at two parts per second is one thing; singling out bulk-loaded workpieces for quality control before sending them hurtling through the machine is quite another. Compli ing things even further, parts had to be separated again after the grind for final inspection.
Throughfeed Grinding Throughfeed grinding also known as thrufeed grinding is the process of feeding the part through the regulating wheel and the grinding wheel. Throughfeed grinding is used for simple cylindrical parts. The regulating wheel is angled to the
This paper proposes an alternative centerless grinding technique, i.e., through-feed centerless grinding using a surface grinder. In the new method, a compact centerless grinding
However, in through-feed type centerless grinding the workpiece needs not only rotational motion but also through-feed motion along the Z-direction, thus the ultrasonic shoe is tilted at a small angle, i.e. γ ≠ 0 see Fig. 1 a , so as to provide sufficientF fa
For improving throughfeed centreless grinding accuracy it is also necessary to ensure a grinding gap macro geometry that suppresses variation of the grinding depth Hashimoto and Kanai, 1983 . This can be achieved by appropriate truing of the regulating wheel and grinding gap set-up.
Centerless grinding is used in a number of industries such as automotive, aviation, aerospace, bearing, consumer products, glass, medical and tool and die. TGS centerless grinding machines can accommodate both throughfeed and infeed grinding and are suitable for a variety of industries.
Interestingly, an in-feed grinding machine can be fixed into place for a specific diameter gap to be used for through-feed grinding, but not vice versa. Although the centerless grinding process has been around for nearly a century, modern machines include CNC, laser gaging, and other innovative features designed to enhance precision and the level of automation.
Rest Plates are used for throughfeed appli ions to support work as it approaches and leaves the regulating roll standard equipment . 052-0000 Model C 090-6125 Model C6 Steady Rest Assembly is for grinding small diameter steps which are relatively long
