Salient Features :

» Heavy duty CNC Gear to bring in more flexibility and productivity.
» HMT Gear Hobbing Machine H400CNC, with its principle of power transmission from motor to hob through shortest path possible is designed to deal with the static and dynamic requirements that would yield ideal tooth form in spite of interrupted cuts peculiar to hobbing processes.
» Radial Feed (X-Axis) :- Designed to give more accurate and desired positioning with high precision ballscrew through AC servomotor. Ensures control over size through rotary encoder for positional feed back. Multiple cuts can be programmed enabling to cut gear of higher module (> 8 mm).
» Axial Feed (Z-Axis) :- AC Servomotor having position feed back through a rotary encoder ensures precise axial feed through ballscrew. AC Servomotor with mechanical fail-safe brake prevents vertical slide inching down during power off/power failure. Optimum cycle time can be achieved by programming higher feed rates during approach and at the end of cut where material removal is less.
» Tangential Feed (Y-Axis) :- Is through precision ballscrew driven by AC Servomotor and feed back through rotary encoder. Infinitely variable tangential feed is provided in H400CNC 4A and stepped hob shift in H400CNC 3A that enable precise orientation of gear teeth. Stepped hob shift in H400CNC 2A is through hydraulics.
» Differential Mechanism driven through AC servomotor (B-axis) in H400CNC 4A & through differential change gears in H400CNC 3A/2A..
» AC Spindle drive & motor for infinitely variable spindle speed offers greater flexibility for cutting gear at different speeds during roughing and finishing to obtain optimal cycle time.
» Programming for multiple cuts, feed rate change, feed direction change, dwell time, skip feed, climb & conventional hobbing, etc. provide lot of flexibility to operator.
» Operator messages for hob change, job inspection and total number of components is available.
