![]() ![]() ![]() A shaper is used to generate flat (plane) surfaces by means of a single-point cutting tool similar to a lathe tool.Shaper is a reciprocating type of machine tool in which the ram moves the cutting tool backward and forwards in a straight line.A lathe is used for many operations such as turning, threading, facing, grooving, Knurling, Chamfering, centre drilling etc.A lathe is a machine tool which holds the job in between the centre and base and rotates the job and rotates the job on its own axis.It is the first operation done internally for any further operation.Drilling is the production of cylindrical holes of definite diameters in workpieces by using a multi-point cutting tool called a ‘drill’.Properly set up, it isn't, cuts like butter at the right RPMs. After reading all the other posts from people who had problems cutting cold rolled steel on mini-lathes (without chattering), I had initially assumed it was a challenge for these little lathes. I now know to use previous experience as the guide, and don't simply chalk up oddities to a different lathe and tools. Last night I thought about it, and remembered the pressure to start the cut seemed just a bit high ( but, because the Gibs are a bit tight still, I didn't know if some of the resistance felt was the too-tight gibs), at the time I chalked it up to " new tool and new lathe which may feel different". When things go weird, always go back to your basic setup and confirm things all over again. ![]() I am surprised it didn't do far worse than "chatter". resulting in a tool that was set too high. I had aligned the top surface of my cutter to the reference. My vertical reference for center height had got "bumped" and was about 1/64th high. Well it was a simple problem, with a simple fix. ![]()
