Heavy Duty Lathe

Q : What is a tool post grinder?

A tool post grinder is a compact size grinder that can be mounted on the tool post or the carriage to grind parts after the turning operation.   Normally since the grinding dust may be abrasive, Turret recommends that the bed way of the lathe should be covered in telescopic guards or accordion type covers.  Turret has extenstive experience in building turning + grinding lathes.   Please contact us for more technical details.  

Q : On the CNC heavy duty lathe, what is a double turret configuration?

Sometimes the customer may use a disc turret on the front side of the carriage, and mount a 4 way turret on the rear side of the carriage.  The disc turret is for the mounting of the external cutting tools, while the 4 way turret is for mounting of the large diameter boring tools.   The double turret configuration provides the customer with variety in cutting tools selection, less tool changing time, and more stability for the boring tools.  However, the working area may have more interference, and the maximum cutting diameter is also reduced.   

Q : On the CNC or conventional heavy duty lathe, can I get a double chuck (front + rear chuck) configuration?

Yes.  Turret has extensive experience in the installation of double chuck configuration.  The double chucks are normally used on heavy duty lathes with large spindle bores, such as the oil country lathes.  A rear chuck adaptor is required for the mounting of the rear chuck to the back side of the spindle.  The double chucks are normally steel body 4 jaw chucks.  

Q : What is built-in rotary tailstock?

In most cases, the operator will use an external live center to put in the tailstock quill.  However, if the operator is using live center to support very heavy parts, sometime the machine part is too heavy for the external live center mounting on the quill because the quill is extending out too long.  In this case, it is better to use the built-in rotary center.  In the built-in rotary center, the live center is built inside the quill with double bearing support configuration.  The diameter of the built-in rotary tailstock¡¦s quill is also much bigger than the standard quill, normally 25% bigger.  The bearing surface of the tailstock base is also larger, providing even more stability, but the lathe¡¦s distance between center may be reduced due to the longer quill design.
