TRANSFER AND UNIT MACHINE
While the specific intention and application for transfer and unit machine vary from one machine type to another, all forms of transfer and unit machine have common benefits. Here are but a few of the more important benefits offered by TRANSFER AND UNIT MACHINE equipment.
The first benefit offered by all forms of transfer and unit machine is improved automation. The operator intervention related to producing workpieces can be reduced or eliminated. Many transfer and unit machine can run unattended during their entire machining cycle, freeing the operator to do other tasks. This gives the transfer and unit machine user several side benefits including reduced operator fatigue, fewer mistakes caused by human error, and consistent and predictable machining time for each workpiece. Since the machine will be running under program control, the skill level required of the transfer and unit machine operator (related to basic machining practice) is also reduced as compared to a machinist producing workpieces with conventional machine tools.
The second major benefit of transfer and unit machine technology is consistent and accurate workpieces. Today's transfer and unit machines boast almost unbelievable accuracy and repeatability specifications. This means that once a program is verified, two, ten, or one thousand identical workpieces can be easily produced with precision and consistency.
rd benefit offered by most forms of transfer and unit
machine tools is flexibility. Since these machines are run from programs, running a different workpiece is almost as easy as loading a different program. Once a program has been verified and executed for one production run, it can be easily recalled the next time the workpiece is to be run. This leads to yet another benefit, fast change over. Since these machines are very easy to set up and run, and since programs can be easily loaded, they allow very short setup time. This is imperative w

日About TOOL
Machine Tool (transfer and unit machine) machine tool is based on common components, together with the workpiece by a specific shape and design of special processing technology parts and fixtures, consisting of semi-automatic or automatic machine tools. Machines and mechanical and electrical auto line is an integrated set of higher degree of automation of manufacturing technology and complete technology and equipment. It is characterized by high efficiency, high-quality, economical and practical, they have been widely used in construction machinery, transportation, energy, industry, light industry, household appliances and other industries. The combination of traditional machine tools and machine tools automatic production line mainly uses the combination of mechanical, electrical, gas, hydraulic control, its main targets is the production of bulk processing of large and medium-sized box type, and shaft parts to complete the drilling, reaming, reaming and processing of various threads, boring, and the boss end cars, tanks of various shapes in the hole boring, and milling and forming flat noodles. As technology advances, a new combination of tools - flexible machine tool more and more people of all ages, it applied a number of spindle box, you can change the spindle box, code accompanying the automatic replacement of fixtures and tools, together with the available programmable controller (PLC), numerical control (NC), able to arbitrarily change the duty cycle control and drive systems, and the flexibility to adapt to variety the adjustable variable combination of processing machine.
Combination of machining methods. Generally use multi-axis machine tool, multi tool, multi-process, multi-faceted or multi-station while processing means higher productivity than the general machine several times to several times. The common parts have been
