Quick change BT30 spindle for my mill.
MJP:
So I have been having problems with my mill not having enough rpm for smaller endmills.
Started looking for a new spindle and motor, but wow do they cost a lot!
BT30 size spindle and motor from china starts around 3000€
Well I have a CNC mill and a lathe, so in comes the planning.
Started with 100mm barstock
Some angular contact bearings
Ball gripper release mechanism
Modified 1.5KW highspeed motor
Assemble everything
And ended with a lever actuated BT30 quick change spindle unit now in running in period for the bearings.

Nice work Marko. I like the lever actuated release mechanism.
MJP:
Thanks Jody,
It has a dual purpose, I can use it manually now that I dont have a tool magazine and when I do then I'll just attach a pneumatic cylinder to it.

MJP:
Spindle mounted to the Z axis slide frame, will be mounting it to the machine tomorrow.
Sorry about the mess on the table, its like something exploded in the shop.
Marko
MJP:
Spindle up on the mill, Z axis slide is locked for the time being. Still needs servo support plate and drive belt.
But I can use the table Z axis like before for now.
