Synchronizer ring
The synchronizer is a component of the manual gearbox. Its function is to force the driving gear and the driven gear to have the same speed when the transmission is shifting, so that the two gears mesh together quickly to avoid noise and vibration and ensure the gearbox Smooth shifting. The synchronizer ring (combination sleeve) is connected with the shift fork to execute the movement transmitted by the shift handle.
The challenge you face
1.Improve production efficiency while reducing costs
2.Ensure product dimensional accuracy

-The two sides of the synchronizer ring are processed by the plunge turning process, the cutting distance is significantly shortened, and the processing efficiency is significantly improved
-Use the entire cutting edge length of the CBN insert to cut, which improves the utilization of the cutting edge of the insert
-Two different cutting edges of the same tool tip are used to make full use of the cutting edge
-Stable quality of processed products
-Long work life
Case
Process both sides of a certain type of synchronizer ring groove, hardness HB680, surface finish requirement Rz 2.0
Blade: VBGW160404S-00515-TTL6B, CBN150
Processing parameters:
Vc=185 m/min,
Feed per tooth f=0.03 (cutting in)/0.05 (finishing turning);
Tool life: 1200 pieces/edge;
Non-standard MDT slot cutter
-The bottom surface of the synchronizer ring is processed by the plunge turning process, the cutting distance is significantly shortened, and the processing efficiency is significantly improved

Moresuperhard provide quality cnc diamond grinding wheel for grinding rotary cutting tools.1A1,1V1,11V9,12V9 abrasives grinding wheel suit for anca,walter,ewag cnc grinding machine.1. Suitable for high-efficiency grinding processing with rapid feed.2. Good wear resistance and shape retention.3. It has good self-sharpening properties, generates less heat during grinding, reduces burns on the workpiece, and meets the high-precision requirements of the tool.4. No clogging, easy to trim, extend the trimming cycle and reduce processing costs. 5. The cutting edge quality of the grinding workpiece is consistent and the smoothness is high, which ensures stable quality when processing downstream products.
At present, the main diamond processing methods include mechanical polishing, thermochemical polishing, tribochemical polishing, laser polishing, ion beam polishing and chemical mechanical polishing.Due to the anisotropy of diamond, "hard" and "soft" polishing directions have completely different material removal rates.Experimental results show that atomic-level roughness values can be obtained in a shorter time by mechanical polishing in the crystallographic directions <100> and <110> or in another direction deviating from <110> at an angle not exceeding 20°.
