An overview of precision machine tool

The requirement of frequency domain error is generally reflected in several specified frequency bands, and the requirement in each band is different. Countries attached great importance to development of ultra-precision machine tool technology.

When the frequency of low-frequency error is larger than 0.

difference between machine and machine tool

Water Jet Cutters In CNC machining, water jets are tools that cut hard materials, such as granite and metal, with high-pressure applications of water. In order to process the extremely large telescope lenses, Cranfield University and Loxham Precision Company developed Big OptiX BOX which was recognized the new large ultra-precision grinding machines in For solving this problem, and also for lessening the dependence on the engineering experience and improving the methodological portability, a new static accuracy design method of UPM based on global optimization and error sensitivity analysis was presented by Chen et al.

In: Precision Manufacturing. The results are shown in Table 2. The linear static pressure guide trips of X and Z are mm and mm respectively. NAM machine. The design of high precision machines involves some basic principles and methodologies which are presented in depth further on.

machine tool supplies

NC machines used a series of numbers punched on paper tape or punched cards to control their motion. Rank Tailor Hobson Company of United Kingdom developed a Nano-form ultra-precision mirror surface machining machine and the feeding mechanism also used friction drive, It can get 1.

For example, ultra-precision shafting has been successfully developed with rotary precision of 0. The fourth category covers modern machine tools and processes for machining ultrahard metals not machinable by older methods.
