Quick-change steel holder mount for rear support of the PM5000
The project
As no additional tool / workpiece can be clamped on the rear support of the PM5000 lathe, a holder for a quick-change steel holder based on the "Multifix" system was manufactured in-house.
For legal reasons, we must point out that the conversion or modification of a machine can lead to the loss of CE conformity and the manufacturer's product liability. Paulitschek Maschinen- und Warenvertriebsgesellschaft mbH accepts no responsibility if the machine is not operated as intended or has been significantly modified after the conversion.
Tools / material used
- Drilling / milling machine
- Shell end mill
- Unalloyed structural steel: E 295 (St 50-2)
Procedure
Step 1
Create the base plate
Firstly, the base plate for the holder was created. The dimensions are:
Length = 180 mm, width = 130 mm and height = 30 mm.
The material used was E 295 (St 50-2). The material E 295 (material number 1.0050) is an unalloyed structural steel. It is used for simple applications in mechanical engineering and has a tensile strength of 400 - 660 N/mm, depending on the dimensions.2.
Step 2
Drilling the holes
The four holes for mounting on the support, the three holes for the grease nipples and the two T-slots were then drilled.
Step 3
Making the mounting block and washer
In order to be able to set the correct working position of the quick-change steel holder, a T-slot was also made in the mounting block in the next step. This allows the quick-change steel holder to be moved along the X and Y axes using the "Multifix" system.
A washer was also produced so that the quick-change steel holder rests on the entire surface of the mounting block.
The mounting block and the washer were made from the material E295 (St 50-2).
Step 4
Align and screw down the quick-change steel holder
Finally, the quick-change steel holder was aligned to the 3-jaw chuck using the "Multifix" system and then screwed tight.
