May 16, 2021 A thread-grinding machine closely resembles a cylindrical grinder in appearance. It incorporates a precision lead screw to produce the correct pitch or lead on the threaded part. Thread-grinding machines also have a means of dressing or truing the cutting periphery of the grinding wheel so it will produce a precise thread form on the part.
PPT can also batch, blend and classify materials to your requirements. All toll processing operations performed at our ISO 9001:2008 facility are fully documented and are overseen by our team of materials engineers. Depending on the size and complexity of the processing job, turnaround times for powder processing can be as short as one week.
Rail grinding is a process that is usually performed by railbound machines. These machines remove metal from the rail using rotating grinding wheels (stones). The volume of metal removed is dependent upon the number and arrangement of stones on each rail, the characteristics and condition of the abrasive in the stones, the application pressure on
Inside diameter grinding, also called as internal grinding, is used for grinding the inner diameter of tubular object. Workpiece or object will have already drilled hole and internal grinding process will be performed to finish the inner surface of workpiece with the help of small grinding wheel rotating at higher revolution per minute.

Machining. Machining is manufacturing process that involves removing materials using cutting tools for getting rid of the unwanted materials from some workpiece and converting it into the shape you desire. A large piece of stock is used for cutting the workpiece. The large stock might be in any shape such as solid bar, flat sheet, beam or even hollow tubes.
machine and a plain horizontal milling machine is the addition of a table swivel housing between the table and the saddle of the universal machine. This permits the table to swing up to 45 in either direction for angular and helical milling operations. The universal machine …
Jul 26, 2020 A capstan and turret lathe is used to manufacture any number of identical workpieces in less time. These lathes are the development of engine lathes. For the first time in 1860, Pratt and Whitney developed the capstan lathe. The capstan and turret lathe consists of: Bed; All geared headstock; A saddle provided on which a 4-station tool-post is mounted to …
It is an extremely versatile machine used to perform a variety of grinding operations: surface, cylindrical, or complex shapes. The image shows a manually operated setup, however highly automated Computer Numerical Control (CNC) machines are becoming increasingly common due to the complexities involved in the process.
