產品詳敘
ECOROLL G型滾光刀具
圓柱型內孔加工，直徑可達200mm
通孔： Ø 4 - 200 mm
盲孔： Ø 6 - 200 mm
產品特性：
- 加工工件公差最低要求IT8（加工薄壁工件時最低要求IT9）。
- GE型在加工直徑50 mm和更大的孔時，工件公差最低要求IT11。
- 可加工抗拉強度≤ 1400N/mm2，洛氏硬度HRC ≤ 45的金屬材料。
- 表面品質可達Rz < 1 μm / Ra ≤ 0.1 μm。
- 可用於CNC鑽床、銑床和車床，加工中心或普通機床。
- 加工時順時針旋轉。
- 可選內部冷卻潤滑功能，配直柄、VDI、HSK、Capto或類似刀柄。
優點：
- 功能可靠，精度高。
- 加工週期短。
- 直徑調整簡單，可重複。
- 潤滑需求低（油或乳化液）。
- 工具在退回時自動收縮，以防止損壞滾柱的滾光面。
- 磨損件容易更換。
設計：
- G型工具包含基本刀體和滾壓頭。
- 刀體包含了刀柄和變徑機構。該機構能以1μm的增量改變
- 工具的滾壓直徑。
- 刀柄可選直柄或莫氏錐柄，也可根據需求定制。
- 滾壓頭包括芯軸、保持架和滾柱。
- 在相同刀體直徑範圍內，滾壓頭可更換。根據需求，工具
- 可以配備自動進給功能（僅建議用於手動進給機床，例如箱柱式鑽床）。
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)).
