APK9332X CNC Gear Chamfering Machine, Synchronous Chamfering Machine

Working principle:

Armpre Machinery developed APK9332X Synchronous Chamfering Machine, the machine adopts the the theory of rotating milling and cycloid principle, the cutter spindle and workpiece spindle are rotated at the same time, one time feed to depth so that complete all teeth processing so the machining efficient can be doubled compared with Index Chamfering machine, The machine can achieve continuous cutting and also indexing cutting.

The machine is characterized by the high-rigidity, high-efficiency, high-accurate, convenient adjustment and operation and stable performance, etc.

Machine Structure:

The machine adopts SIEMENS 828Dsl CNC control system, it equipped with electric gear box function so that improve the functional performance.

There are six- axes on the machine: 1. Workpiece rotation; 2. Two cutter spindle rotation; 3. Workpiece headstock feed; 4. Two cutter spindle feed. The workpiece rotation adopts direct driving torque motor and closed loop control.

The cutter spindle adopts high-speed servo motor and connects with cutter spindle directly so that drive the cutter spindle rotation, and avoided transmission clearance and error, the processing accuracy is improved.

The two independent cutter spindles are side-suspended from a column, which can be independently moved along the vertical and horizontal rotation, whole cutter support can moved along horizontal、longitudinal and vertical direction. The linear adjustment section adopts rectangular & dovetail guides and rotation axis uses a pair of angular contact ball bearing so as to changing the workpiece is more fast and convenient.

The machine adopts standard chamfering cutter holder & ordinary cutter tip. The alarm diagnosis function of the machine tool can help the user to eliminate the malfunction of machine tool in time and reduce the waiting time of the user to stop the operation, thus ensuring the smooth production.

The machine adopts the non-contact matching tooth of the sensor. The high-precision sensor greatly improves the precision of the tooth, and also avoids the contact tooth, the damage of the workpiece and the wear of the tooth mechanism, and ensures the stability of the tooth precision.
