End-of-arm tooling is the key to successful to robotics applications such as drilling. Switzerland-based OTTO SUHNER AG said its POLYDrill family includes a large selection of multi-spindle heads from the standard range.
SUHNER said it can supply tool holders from all stock for all popular brands of machining centers. Fixed and adjustable hole pitches and compact models allow the POLYDrill tool to be used in a variety of situations, said the company. It recently also released end effectors for industrial machining.
POLYDrill specifications
Drilling capacity is available standard between 0.06 and 1 in. (1.5-25 mm), according to SUHNER. Minimum hole spacing is 0.27” (7 mm), while maximum hole spacing is virtually limitless, it said.
Optional tool holders include ER, ST, JT33, Weldon, and customized styles for robotics developers, integrators, and users. Additional options are axial and radial compensation and custom layout and spacing, said SUHNER.
The POLYDrill range includes various multi-spindle heads such as MH 20/5, MH 20/7, MH 20/10 and MH 20/13. In addition, multiple spindle heads with adjustable spindles provide flexibility.
The MH 20/5, 20/7, MH 20/10 have maximum speed of 4000 RPM. Maximum drilling capacities are 5 mm, 7 mm, and 10 mm, respectively. MH 20/13 has a maximum drilling capacity of 13 mm and a maximum permissible speed of 3,000 RPM.

Multiple spindles
The MHF POLYDrill has up to 10 spindles, a custom made pattern and a fixed spindle distance. Maximum drilling capacity is five to 13 mm, and the speed range is 2,500 to 4,000 RPM. MHFP is equipped with eight spindles with preloaded angular contact bearings for use of carbide tools and fixed spindle distance.
Maximum drilling capacity is between 7 and 20 and the speed range is 0 to 8,000 RPM. The drive system VG 4-8 allows the user to power up to eight machining units with a single motor with flex shaft power delivery. The speed range for this drive system is between 46 and 9,320 RPM. Flexible drive shafts NA 7/10/12 have a speed range of 12,000 to 20,000 RPM, said SUHNER.
We are looking for an equipment that can drill 16 holes on one side of an ”I”Beam (8.5 Feet long). Do you think you can propose me something. We are from Canada !
