RA型
加工外圆柱面
直径：Ø 3 – 160 mm
产品特性：
加工工件公差要求IT8。
特别版RAP型工具具有滚压力控制功能，加工工件公差要求IT11。
可加工抗拉强度≤ 1400N/mm2，洛氏硬度HRC ≤ 45的金属材料。
表面质量可达Rz < 1 μm/ Ra ≤ 0.1 μm。
可用于CNC钻床、铣床和车床，加工中心或普通机床。
加工时顺时针旋转。
可选内部冷却-润滑功能，配直柄、VDI、或HSK刀柄。
优点：
功能稳定，精度高。
加工周期短。
直径调整简单，可重复。
润滑需求低（油或乳化液）。
工具在退回时自动收缩，以防止损坏滚柱的滚光面。
磨损件容易更换。
设计：
包含基本刀体和滚压头。
刀体包含刀柄和变径机构。该机构可调整工具滚压直径，重复性好。
莫氏锥柄和实心直柄用于有限滚光长度；中空直柄用于无限滚光长度。
滚压头包括芯轴、保持架和滚柱。
滚压头在相同刀体直径范围内可更换。

TYPE RA:
Machining cylindrical ouexternal surfaces
Diameter: Ø 3 – 160 mm
Features:
Can be used up to tolerance class IT8.
Special version RAP with pressure-controlled expansion is available for tolerances ≤ IT11.
Machines all metal materials up to a tensile strength of 1400 N/mm2 and a maximum hardness of HRC ≤ 45.
Can achieve a surface quality of Rz < 1 μm / Ra ≤ 0.1 μm).
For use on CNC-controlled drilling or milling machines and lathes, machining centers or conventional machine tools.
Machining with clockwise rotation.
Optional internal cooling-lubricant supply possible with straight shank, VDI shank or HSK.
Advantages:
Reliable function, high degree of accuracy.
Short cycle time.
Diameter adjustment is easy and reproducible.
Requires minimal lubrication (oil or emulsion).
Tool automatically contracts upon retraction, preventing damage to the roller burnished surface.
Wear parts are easy to exchange.
Design:
Consists of a basic tool body and a burnishing head.
The tool body contains the tool shank as well as the mechanism for the infi nitely variable and reproducible setting of the rolling diameter.
Morse taper and solid straight shanks for limited burnishing lengths. Perforated straight shanks for unlimited burnishing lengths.
The burnishing head consists of the outer cone, cage and rollers.
Burnishing heads are replaceable within the diameter range.
