MODIFICATION OF PLANER MACHINE TO PLANO MILLING MACHINE
What is planer?
A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear toolpath.
A planer is analogous to a shaper, but larger, and with the entire workpiece moving on a table beneath the cutter, instead of the cutter riding a ram that moves above a stationary workpiece. The table is moved back and forth on the bed beneath the cutting head either by mechanical means, such as a rack and pinion drive or a leadscrew.
MODIFICATION OF PLANER MACHINE TO PLANO MILLING MACHINE Modification :
Replacement of rack and pinion arrangement by hydraulic power pack.
Installation of controllable DC motor instead of manual operation, for the cross movement of tool head.
Installation of AC motor in tool head for spindle rotation replacing single point cutting tool.
MODIFICATION OF PLANER MACHINE TO PLANO MILLING MACHINE Need for modification :
It was only used for planing purpose.
Rack and pinion arrangement was old and complex technique.
Elimination of manual operation for cross movement of tool head.
For using various tools.
MODIFICATION OF PLANER MACHINE TO PLANO MILLING MACHINE Advantages :
After modification of planer ,we can perform various operations such as planing, milling, drilling, sloting etc.
Reduction in work handling time due to various operation performed on the same machine.
It can generate accurate flat surfaces.
MODIFICATION OF PLANER MACHINE TO PLANO MILLING MACHINE Applications :
It is very much useful for industry to start a new production line.
Machining of oil pan used in the engine.
