DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE ART
This invention relates to a composite processing machine having processing functions such as a cutting process, a discharge process, a grinding process and the like which is suitable for use with fabrication of principally molding molds.
BACKGROUND
Generally, cavity processing of a molding mold used for injection molding, compression molding and transfer molding of synthetic resins, and die casting molding of metal and the like is accomplished principally by combination of cutting process using milling and process using discharge. Two machine tools, a milling machine and a discharge processing machine, are used for the aforesaid process.
Because of the foregoing, there arises problems that a wide installation space for the machine tools in the factory is required, equipment cost increases, time required for movement of work between the processing machines and locating thereof and required for arrangements attended by preparation work programs increases, and the processing precision is deteriorated.
DISCLOSURE OF THE INVENTION
This invention has been achieved in order to solve the above-described problems. It is an object of this invention to provide a new composite processing machine, which even a single machine, has many processing functions such as cutting process in the form of milling, drilling process in the form of a drill, discharge process and the like, while paying attention to a common point in construction between a milling machine and a discharge processing machine.
It is a further object of this invention to provide a new composite processing machine which can also carry out grinding process of molds according to an electrolytic inprocess dressing grinding process utilizing discharge process means.
In this invention for achieving the aforementioned objects, there comprises a work table having on the upper surface thereof a liquid tank for accomodating and securing a work, means for moving the work table in a direction of X and Y axes, a processing unit wherein a chuck capable of detachably mounting various tools and a discharge electrode is provided on the fore end of a spindle positioned upwardly of the work table and which is provided with a motor for rotating the spindle and a fixing brake, means for moving the processing unit in a direction of z-axis, an auto tool changer (ATC) which holds a cutting tool, a discharge electrode, a measuring probe, a grinding wheel and the like to selectively feed them to the chuck, and a processing power source connected over the discharge electrode mounted on the chuck or the grinding wheel and the work within the liquid tank or a nozzle for a coolant to apply a dc current thereto.
In the composite processing machine according to this invention, the liquid tank on the work table is filled a processing liquid for discharge, after which a work is set within the liquid tank, and the processing unit is moved down with respect to the work. If a tool mounted on the chuck at the fore end of the spindle is one used for cutting or drilling, cutting or drilling of the work is carried out by rotation of the spindle. If a tool is a discharge electrode, the chuck side thereof is set to pole (+) while the work side thereof is set to pole (-), and a dc current is applied from the processing power source to effect discharge processing.
In case of effecting the grinding process by the electrolytic in-process dressing grinding process, the processing liquid is removed from the liquid tank, and the grinding wheel side thereof is set to pole (+) while the coolant nozzle side provided within the liquid tank is set pole (-) for dressing, and a dc current is applied from the processing power source.
The tools used for the above-described processes or measurement are supplied from ATC to the chuck according to the work steps, and a new tool is exchanged with the tool mounted on the chuck by ATC.
The composite processing machine according to the present invention has both the milling processing function and discharge processing function as well as the elect
