Tape finish with Thielenhaus machines

Our wide range of tape finishing machines can meet the most diverse requirements – whether the customer demands productivity, quality, flexibility or efficiency.

Tape finishing machines for the greatest precision with shaft and cylindrical parts

9e160bf019

Tape finishing is a frequently used technology which can be used to achieve extremely precise surfaces for shafts and cylindrical parts. This includes, for example, cams and roller bearing positions in camshafts, as well as balance shafts, camshafts and the surfaces of rollers, roller bearings or printers. 

Tape finishing can also be used to minimise the amount of surface roughness, as well as to optimise the cylindricity or reduce the amount of fine waviness. The abrasive tape finishing tool is mass-produced and can therefore be purchased at relatively low cost. Tape finishing is thus among the most flexible and cost-effective finishing processes.

YOUR BENEFITS

Individually adjustable machining parameters

One particular benefit of Thielenhaus tape finishing machines is that all machining parameters, for example the oscillating frequency and stroke, as well as the tape feed, can be set flexibly and for each individual tape finishing unit in the machine’s controls. This allows users to take a very targeted approach to the different requirements for the same component.

Greater process reliability

Process reliability can be optimised on the tape finishing machines by way of various monitoring systems. These include tape end, tape feed-through and tape tear monitoring elements. Furthermore, the unit’s oscillation can also be monitored. This ensures that no unfinished parts are produced.

TAPE FINISHING: HOW IT WORKS

bandfinishen

Generally speaking, tape finishing machines combine two movements: oscillation and rotation. In the majority of cases, the tape finishing tool oscillates on the work piece surface, while the work piece is rotated. With particularly heavy components such as, for example, an HGV crankshaft, it is possible that not only the rotation but also the oscillation is done by the work piece.

In both cases the combination of movements generates the crosshatch finish typical of the Microfinish process. During the finishing operation the tape is constantly pulled through by a drive motor in the device or by the machine, in order to ensure that the cutting grain is always being replaced.
