CNC lathe for multiple operations with several chuck and toolholder configurations
The Romi C 420 CNC Lathe is truly versatile machine that can handle many different types of workpieces. High power cuts, rapid tool positioning and precision are attributes of which you can be assured.
The high performance and reliable hardware of the Siemens Sinumerik 802D sl-Plus CNC Control offers multiple means of programming and operating, including a Graphic module for machining simulation.
This machine can be equipped with RMMP – Romi Manual Machining Package (optional) that allows simple operations to be completed without any type of programming. It is as simple to use as an Engine Lathe but with the added capability and productivity of a CNC Lathe.
RMMP – Romi Manual Machining Package (optional)
This application allows the user to operate the machine in both manual and auto mode. There are three levels of operation according to the operator skill:
Manual Mode
The operator machines the part as on a conventional lathe using Control Apron. In this mode, manual operations such as Parallel Turning, Taper Turning, Radius Turning, Drilling and Groove can be performed.
Cycles Mode
In this mode the machinist operates the machine in semi automatic mode. He fills in the conversational screen fields for feed, speed and cycle data, then moves the tool to a safe starting point using the Control Apron and then presses the Cycle Start button to perform the cycle.Cycles as Drilling, Tapping, Groove / Parting, Thread and Roughing / Finishing Turning can also be performed. There are fixed cycles and free form for turning. The filling in of the cycles fields are aided by a graphic screen.
Teach In Mode
In this mode the operator saves the operations step by step as he is machining the first part. The operator can then save these into a program for use on later parts. Both manual operations and cycles operations can be saved together into the same program and the programs can then be saved in the CNC memory or a compact flash card.
