What Are The fundamental ideas of internal gear machining?
Internal gear machining calls for a unique turning tool-akin to a helical gear shaper. Mounted on mutually intersecting axes, the tooth blank and the tool generate a condition of internal tooth meshing. The gear is machined by causing the gear blank and the cutter to revolve concurrently feeding the cutter along the axial direction of the gear blank. Sliding is used to realise the normal machining of the gear by means of the synthesis of the circumferential speed of the tool pitch circle and the feed force of the machine tool, thereby generating the cutting force.
Which benefits internal gear machining offers?
strong processing efficiency
Internal gear processing efficiency ranges from two to four times that of the gear shaping technique, thereby greatly enhancing production efficiency.
No impact force, sturdy instrument
The loss of the tool is minimal and the service life is lengthy as the cutting operation lacks reciprocating cutting action.
Low tool expenses
Internal gear machining makes use of quite low-cost, easily resharpenable and maintained tools.
