Recoo Dedicated CNC machining, mainly provides precision parts machining, precision machining, CNC machining, 
CNC precision machining, CNC machining of complex parts.
In precision manufacturing industries, measurement tools and surveying people skills are very important, on the selection 
of measuring equipment, not more complex, more expensive, the better, but according to the structure and measurement 
of position, selection of suitable measuring equipment and measuring techniques.Teng-sheng company focused on high-end products, precision machining, manufacturing, testing, with all kinds of measuring equipment, in respect of three-coordinate measuring apparatus and measuring devices are described and compared the advantages and disadvantages:
 
1, measurement of three-coordinate measuring machine is detecting instrument, its advantages are:
(1) high measurement accuracy, 
(2) three dimensions measurement can be accomplished, and 
(3) measuring range.Three-coordinate measuring machine is more authoritative in the measuring device, but it also has many faults, 
(1) measurement of low efficiency, (2) measurement of higher costs, and (3) higher skill requirements for surveyors, 
and (4) maintenance of equipment costs higher.
 
2, image measuring instrument are optical measuring instruments, its advantages: (1) measurement of efficiency, in particular 
the automatic image measuring instrument, (2) or arc to automatically match the access point automatically through software, 
greatly increasing the number of measurement points, so that the measuring values close to the objective, (3) simple operation, 
low maintenance costs.But it also has more limitations: (1) most image measuring instrument belongs to two dimensions, even 
when you have z axis probe 2.5, measurement products only in the finite-dimensional space, and (2) complex, cannot be effectively 
projected location, imaging equipment, and (3) the lower part of shape and position tolerance measurement accuracy.
 
3, measuring fixture: mass production of products, in order to improve the measurement of efficiency and accuracy, and less 
dependent on measuring the skills, companies are advocating to produce appropriate test fixture for measuring, measuring fixture 
fabrication needs of upfront costs, such as batch production, is very suitable for measuring test fixture.
By the above analysis, measurement of the product either device, the result can only be said to be relatively accurate, test accuracy 
depend on the combined, such as equipment, methods, product structure.
