Chapter 17: Grinding Methods and Machines - American Machinist
WEBJun 29, 2020 — 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.
Understanding PTFE, and How to Use It | American Machinist
WEBAug 30, 2018 — Some of the practical uses of PTFE out in the real world include: • Coating walls and surfaces in residential or controlled environments, making these non-stick to repel insect and pest intrusions. • In surgery, PTFE is used for tissue and organ grafts, as well as to inhibit infections from catheters and other medical equipment.

Chapter 4: Turning Tools and Operations - American Machinist
WEBJan 19, 2010 — Cutting Tool Applications, Chapter 4: Turning Tools and Operations. Jan. 19, 2010. Turning is used to generate cylindrical surfaces: generation of surfaces oriented primarily perpendicular to the workpiece axis are called facing. In turning, the direction of the feeding motion is predominantly axial with respect to the machine spindle.
5 Common Machine Shop Injuries, and How to Prevent Them
WEBNov 27, 2019 — 2. Clean work areas and stations — The entire machine shop must remain clean, which means all workers are responsible for keeping their areas or workstations tidy. Doing so will prevent common injuries that occur …
5 CNC Machining Trends to Watch in 2022 | American Machinist
WEBFeb 3, 2022 — When people would ordinarily use injection molding for prototypes, they may discover its more efficient to rely on a 3D printer instead.. When accuracy is a concern, CNC machines can achieve tolerances of up to 0.025 millimeters. However, the accuracy for a 3D printer is typically about 0.1 millimeters – another reason that 3D printers are commonly chosen for making prototypes.
Choosing the Right Coolants and Lubricants for Machining
WEBDec 6, 2023 — The right choice depends on many factors. Cooling and lubricating the workpiece using cutting fluids is essential to the machining process. There is a formulation for every application, material, and type of operation, from copper plumbing fittings to titanium jet engines and airframes. The right choice for a specific type of cutting fluid ...
Isolating Unwanted Vibration - American Machinist
WEBMay 1, 2005 — An effective isolator for an application has a natural frequency well below the application's input vibration. If the transmissibility ratio is much greater than one, vibration is amplified, whereas if the ratio is less than this, vibration is reduced. Vibration isolation for any isolator begins at a ratio of 1.414.
Cutting Tool Applications, Chapter 18: Lapping and Honing
WEBJun 29, 2020 — Lapping processes. The principal use of the lapping process is to obtain surfaces that are truly flat and smooth. Lapping is also used to finish round work, such as precision plug gages, to tolerances of 0.0005 in. to 0.00002 in. Work that is to be lapped should be previously finished close to the final size.
Cutting Tool Applications, Chapter 14: Broaches and Broaching
WEBJun 29, 2020 — A broach is a long multi-tooth cutting tool with successively deeper cuts. Broaching is used to machine internal and external surfaces, such as holes, keyways, and teeth of internal gears. The broaching process, similar to shaping with multiple teeth, is used to machine internal and external surfaces such as holes of circular, square, or ...
