The standard accurate machining tools are the centre lathe and universal milling machine and for super finishing, the surface and rotary grinders
More precise working - machines will always be more precise than human hands. Significantly faster production. Cheaper.
They depend on the design of the instrument.

Cylinder out of roundness, or ovality, can be caused by several factors, including improper machining or manufacturing processes, wear and tear from prolonged use, thermal expansion, and insufficient support during the machining process. Additionally, material inconsistencies and improper alignment during assembly can contribute to this issue. Regular maintenance and precise machining techniques are essential to prevent out-of-round conditions.
The cutting speed for machining polypropylene typically ranges from 150 to 300 meters per minute (m/min), depending on the specific machining operation and tooling used. Factors such as the type of cutter, machine conditions, and desired surface finish can influence the optimal cutting speed. It's advisable to start at a conservative speed and adjust based on the material's response and the quality of the machining process. Always consult the tooling manufacturer's recommendations for precise settings.

A machinist uses a metal square to ensure precise measurements and angles when setting up workpieces or aligning tools. The square helps verify that surfaces are square to each other, which is crucial for accuracy in machining operations. It can also be used to mark lines for cutting or machining, ensuring consistent and accurate dimensions. Overall, the metal square is an essential tool for maintaining quality in machining tasks.
Machining process is a broad term that refers to the cutting processes, abrasive processes and the non-traditional machining processes.
By machining steel, stamping it, and machining wood.
