| Exterior size (W*L*H)(mm) | 570*230*270 High Precision Machining High Precision Machining is defined as a process of changing the dimensions or the performance of workpiece with machining facilities. According to the temperature of the workpiece while in machining, high precision machining can be divided into cold working and hot working. Usually, machining under indoor temperature, and won't change cause chemical change or phisical phase change is named cold working. On the other hand, if under temperature, higher or lower than room temperature, which will lead to chemical changes or phase changes, it will be called as hot working. For high precision machining, the machining tolerance can be up to 0.0001-0.001mm, the surface finish Ra can be 0.02-0.1um. Machining precision is to describe the actual geometrical parameter of the part after machining, such as the size, the form, the position, comparing with the theoretical geometry parameter. The difference from these two parameters is the machining tolerance. The number of the difference show the machining accuracy, the bigger, the lower of the machining precision, the smaller, the higher machining precision.
