Continuous machining without clamping
•Model: RC-255
•Driven by Roller Gear Cam
Machining Conditions
•Workpiece Material: Medium Carbon Steel S45C
•Tool Diameter: Ø20mm
•Cutting Depth: 10mm
•Machine Feed Rate: F28mm/min
•Rotary Table Speed: 0.83rpm
RC-255 can withstand the continuous heavy cutting machining. It’s cutting torque is up to 55kgf‧m.
Presents an extremely low surface roughness of the workpiece after cutting.
Achieving perfectly continuous machining by RC-255 relies on two factors:
1. high-rigidity spindle bearings
2. roller gear cams with 90% efficiency.
How does it achieve over 90% conduction efficiency?
The roller cam's rolling contact reduces friction and thermal displacement.
Cam followers in the turret use internal roller bearings
for efficient torque transmission and provide shock resistance, ensuring stability.
•機型: RC-255
•滾子凸輪傳動
加工條件
•工件材質: 中碳鋼
•刀徑: Ø20mm
•切削深度: 10mm
•機床近幾速率: F28mm/min
•分度盤轉速: 0.83rpm
RC-255可承受同動重切削加工，其切削扭矩高達55kgf‧m
工件切削後表面粗糙度極小
RC-255實現完美連續加工的關鍵在於兩個因素：
1. 高剛性的主軸軸承
2. 具有90%效率的滾子凸輪
它是如何實現90%以上的傳導效率的呢？滾子凸輪的滾動接觸減少了摩擦和熱位移。
刀塔中的凸輪從動件採用內部滾柱軸承，可有效傳遞扭矩並提供抗震性，確保穩定性。
