G型滚光刀具
圆柱型内孔加工，直径可达200mm
通孔： Ø 4 - 200 mm
盲孔： Ø 6 - 200 mm
产品特性：
加工工件公差要求IT8（加工薄壁工件时要求IT9）。
GE型在加工直径50 mm和更大的孔时，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、HSK、Capto或类似刀柄。
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：
G型工具包含基本刀体和滚压头。
刀体包含了刀柄和变径机构。该机构能以1μm的增量改变
工具的滚压直径。
刀柄可选直柄或莫氏锥柄，也可根据需求定制。
滚压头包括芯轴、保持架和滚柱。
在相同刀体直径范围内，滚压头可更换。根据需求，工具
可以配备自动进给功能（仅建议用于手动进给机床，例如箱柱式钻床）。
TYPE G:
Machining cylindrical bores up to Ø 200 mm
Through holes: Ø 4 - 200 mm
Blind holes: Ø 6 - 200 mm
Features:
Can be used up to tolerance class IT8 (up to IT9 forthin-walled workpieces).
Type GE up to tolerance class IT11 for Ø of 50 mm and larger.
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, HSK, Capto, or similar shanks.
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
Type G tools consist 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 setting of the rolling diameter in increments of 1 μm.
Tool shanks either with Morse taper or straight shank; special designs by request.
The burnishing head consists of the cone, cage and rollers.
Burnishing heads are replaceable within the diameter range. By request, the tools can be equipped with selffeeding capability (recommended only for machines with manual feed (e.g. box column drilling machines)).
