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.
