A one-way, low-speed (OWLS) diamond in Champaign, Illinois.This is an example of flange-bearing frogs in use on North American freight rail lines. A flange-bearing frog, often abbreviated FBF, is a type of frog in which the flange of the wheel on a railway vehicle supports the weight of the vehicle.
Luckily, diamond's hardness is slightly different along different crystal axes. The particles of diamond on the grinding wheel are randomly oriented, so some of them will be aligned with the harder axes toward the rough diamond to be cut. The rough, therefore, needs to be extensively studied so it can be positioned for optimal cutting on the ...
There are two common methods to manufacture diamond grinding cup wheels: hot pressing and cold pressing. The hot pressing method is to directly sinter the diamond segments in molds under a certain pressure in the dedicated sintering press machine, and then fix or connect the diamond segments onto the grinding wheel’s body via high-frequency welding, laser welding or mechanical mosaic method.

Diamonds on Wheels is a 1973 British family comedy film directed by Jerome Courtland and starring Peter Firth, Patrick Allen, George Sewell, Derek Newark, George Woodbridge and Barry Jackson. [1] It was written by Pierre Castex and William R. Yates.
This invention revolutionized the diamond cutting industry and, correspondingly, greatly increased the popularity of diamonds. [5] The scaif consists of a hard disk, parallel to the floor. The disk looks like and is rotated in the same way as a potter's wheel. On the top surface a film of olive oil and diamond dust is placed.
Designed as a heavy prime mover for tank transporting, the hard-cab Diamond T 980 [2] was the product of the Diamond T Company in Chicago.In 1940 the British Purchasing Commission, looking to equip the British Army with a vehicle capable of transporting larger and heavier tanks, approached a number of American truck manufacturers to assess their models.
Diamond turning is turning using a cutting tool with a diamond tip. It is a process of mechanical machining of precision elements using lathes or derivative machine tools (e.g., turn-mills, rotary transfers) equipped with natural or synthetic diamond-tipped tool bits .
