Angle Heads - Overcome Difficult Machining Occasions The angle head holder can be used for side machining or even specific angle machining and helps you save the production cost. It not only saves the expensive cost of purchasing another machine, but reducing the accuracy deviation caused by rotating and clamping the workpiece again. SYIC uses high-precision P4 class bearings and ground gears for all angle head series to reduce noise and temperature rise during operation. Each angle head holder has passed the temperature rise test before shipment. You can choose suitable series and type for drilling, tapping, milling, or grooving according to your machining demand. No matter it?s light, medium or heavy-duty machining. For the design of output, we can provide 90°, universal type and specific fixed angle type.
