This unit of competency applies to grinding operations performed on surface, cylindrical and centreless grinding machines. It requires use of measuring equipment and standard engineering materials and tooling. Work is performed to established processes, practices and to drawings, sketches, specifications and instructions as appropriate.
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.
Cylindrical grinding Cylindrical grinding is the process of grinding the outside surfaces of a cylinder. These surfaces may be straight, tapered or contoured. Cylindrical grinding operations resemble lathe-turning operations. They replace the lathe when the workpiece is hardened or when extreme accuracy and superior finish are required.
Cylindrical Grinding Cylindrical grinding (also called center-type grinding) is used to grind the cylindrical surfaces and shoulders of the work piece. Surface Grinding Surface grinding is used to produce a smooth finish on flat surfaces. Surface Grinding Operation AIM To perform the fine surface Grinding operation on given work piece.
Cylindrical grinding operations are capable of refinishing both the inner diameter (ID) and the outer diameter (OD) of the workpiece. Form Grinding. Form grinding is a specialized type of cylindrical grinding process in which the grinding wheel has the exact shape of the final product. By design, the grinding wheel doesn't traverse the workpiece.

Figure 3 shows a novel grinding model that accounts for the various setup parameters of cylindrical grinding operations, including the material removal rate, workpiece sizes and grinding speed. In this model, only the static compliance of the grinding machine is considered for the grinding process analysis.
Cylindrical grinding is divided into three general operations: plain cylindrical, conical grinding (taper grinding), and internal grinding. Universal Grinding Machine Cylindrical Grinding Operation Plain Cylindrical Grinding The step-by-step procedure for grinding a straight shaft is given below. The shaft has been roughly turned prior to grinding.
The feed of the grinding wheel is the distance the wheel moves laterally across the workpiece for each revolution of the piece in cylindrical grinding or in each pass of the piece in surface grinding.The following methods are recommended for determine feeds: *The feed should be proportional to the width of wheel face and the finish desired.
NC1 1-4 1.3 MACHINE OPERATION SAFETY Read this manual thoroughly before operating. 1. As an operator or maintenance people, be sure clean all warning plates and not allow
Cylindrical Grinding Operation: The rotating cylindrical workpiece reciprocates laterally along its axis in a grinder used for the large and long workpieces. The grinding wheel reciprocate called a roll grinder cylindrical grinders are identified by the maximum diameter and length of the workpiece that can be ground similar to engine lathes.
Cylindrical grinding is divided into three general operations: plain cylindrical, conical grinding (taper grinding), and internal grinding. The workpiece and wheel are set to rotate in opposite directions at the point of contact (Figure 5-21).
The term "Cylindrical grinding" refers to the all the grinding operations of round and cylindrical pieces that allow us to obtain the most possible roundness of all the details. This process is carried out with utmost precision for both internal and external diameters. Cylindrical grinding is performed by mounting the piece on a spindle ...
In this type of grinding operation two grinding wheels are fitted parallel with a little 5-10 degree angle, this angle is provided to get a longitudinal motion of the workpiece. A cylindrical rod is entered between the two grinding wheel due to the tilted angle the workpiece is automatically pass through the wheels, and we got a smooth surface.
In centerless through feed grinding, which is a typical serial grinding process, pistons for the automotive industry, shafts, rods and also elements for the rolling bearing industry are produced. Internal cylindrical grinding: Internal cylindrical grinding is one of the most common and also most difficult grinding operations.
5 Tips to Enforce World-Class Lockout/Tagout Safety Procedures for Your Grinding Machine. Guest Blogger. Tuesday, 25 July 2017 . Federal OSHA lockout regulations prevent unauthorized operation of a grinding machine when in an "unsafe" condition, such as during service or maintenance when the true state of the machine may be unknown.
Cylindrical grinding is usually a secondary operation after turning. Often the same center holes used for between-centers turning may be used for grinding the part. As friction is more of a factor in grinding than in other processes, fixture design must allow for coolant flow and swarf removal. If not built into the grinding machine itself, the ...

The milder abrasives like 32 and 38 Aluminum Oxide are best for lighter precision grinding operations on steels and semisteels, while the intermediate 57 and 19 Aluminum Oxide abrasives are used for precision and semiprecision grinding of both mild and hard steels. The severity of the grinding operation also influences the choice of grade.
Types of Grinding. Grinding operations come in many types, with this article covering six major types and several of the subtypes within. Cylindrical grinding is a common type of grinding in which both the wheel and the workpiece rotate.
This Grinder (Cylindrical) Standard/Safe Operating Procedure (SOP) provides a way for your business to outline step-by-step safe processes when operating a cylindrical grinder. Provides instructions on the use of the equipment both prior to and during operation. Ensures workers recognise and manage associated hazards and risks involved.
2. Clamp a driving dog onto the workpiece. The wheelhead of a cylindrical grinder moves on. 3. Position the workhead and footstock and set. the horizontal ways (platen). Since cylindrical grinding. the traverse stop dogs so that when the workpiece is in. is done with the axis of the spindle level with the center.
Cylindrical grinding is the practice of grinding cylindrical or conical workpieces by revolving the workpiece in contact with the grinding wheel. Cylindrical grinding is divided into three general operations: plain cylindrical, conical grinding (taper grinding), and internal grinding.
In a cylindrical grinding machine, a round rod (3) to be ground by peeling grinding is clamped in the chuck (2) of a workpiece headstock (1) so that rotation about the common central axis (4) is achieved. The round rod (3) is dragged in the direction of the directional arrow (16) on a stationary mounted rotating grinding wheel (5) along the abrasive.

when performing grinding operations. 7.0 Safe Work Procedures 7.1 Correct Tool Selection If a grinder must be used, chose the right grinder for the job. Do not use a larger, heavier, or more powerful grinder than is necessary for the job as it is much easier to lose control of it.
In the world of manufacturing Health and Safety is of paramount importance. This is especially true when it comes to using industrial machinery. Today most grinding tools are computer operated which means that they require little human input, making them much safer than they used to be. However some companies still use cylindrical grinders and other types …
