Thielenhaus Infinity 900 – 1100

Q: How much does the Thielenhaus Infinity 900 – 1100 cost?

The price estimate for the Thielenhaus Infinity 900 – 1100 is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/thielenhaus-infinity-900-1100#price; the request is passed to Thielenhaus Technologies or an authorised dealer.

Overview

The Thielenhaus Infinity 900 – 1100 is the long version of Thielenhaus's roller finishing machine. Its drive rollers measure 900 – 1,100 mm (35.4 – 43.3 in), it has 10 tool carriers, and the technical data give a machining diameter up to 35 mm (1.4 in).

Length is the point. More drive roller length and more tool carriers than the Infinity 600 put more stones along the path a roller travels, so a part can see more finishing stages in one pass, or the line can feed faster for the same result. The Infinity 600 has 600 mm drive rollers and 8 tool carriers.

Everything else in the table is common to both sizes. Drive roller speed is 0 – 720 rpm. Tool oscillation frequency is 75 – 2,500 double strokes/min, the horizontal tool oscillation stroke 0 – 4 mm (0 – 0.16 in) and the vertical tool oscillation stroke 50 mm (2.0 in). Total connection stays at 9 kW, with 4.5 bar minimum compressed air and 80 l/min of flushing oil, so the longer machine asks nothing more of the plant services.

Thielenhaus lists the Infinity for cylindrical rollers, tapered rollers and needle rollers, with cylinder, crowned and logarithmic profiles as machining solutions, and calls it an automatic machine for small and medium-sized rollers in mass production. Drive roller length is printed as a range. That suggests the length is fixed per order, so ask which one an offered machine has.

Strengths & Limitations

Strengths

Drive roller length of 900 – 1,100 mm, against 600 mm on the Infinity 600
10 tool carriers along the roller path
Machining diameter up to 35 mm (1.4 in)
Same 9 kW total connection and 80 l/min flushing oil flow as the shorter Infinity 600
Cylinder, crowned and logarithmic profiles are listed machining solutions

Limitations

Drive roller speed is the same 0 – 720 rpm as on the shorter machine, so added output comes from length and not from speed
No weight or footprint is given for a machine with drive rollers up to 1,100 mm long
The smallest rollers are the territory of the Infinity 600, whose range begins at 1.5 mm

Best For

Cylindrical and tapered bearing rollers up to 35 mm diameter Mass production that needs more stone stations in one pass Logarithmic and crowned roller profiles Medium-sized rollers beyond the 15 mm main range of the Infinity 600

Frequently Asked Questions

01 What does the model name of the Infinity 900 – 1100 refer to?

It matches the drive roller length. The technical data list drive roller length as 900 – 1,100 mm (35.4 – 43.3 in) for this model and 600 mm for the Infinity 600. The table does not say how a length within that range is chosen, so confirm it for the machine you are offered.

02 What roller diameters can it finish?

The technical data table gives a machining diameter up to 35 mm (1.4 in). Roller types listed are cylindrical rollers, tapered rollers and needle rollers. Smaller rollers are work for the Infinity 600, whose main area of application is 1.5 – 15 mm.

03 How many tool carriers does it have?

The machine has 10 tool carriers; the Infinity 600 has 8. Tool oscillation frequency is 75 – 2,500 double strokes/min with a horizontal tool oscillation stroke of 0 – 4 mm (0 – 0.16 in), and the vertical tool oscillation stroke is 50 mm (2.0 in).

04 What connections does it need?

A total connection of 9 kW, a minimum of 4.5 bar compressed air and a flushing oil flow rate of 80 l/min. Those are the same values as for the Infinity 600, so the two sizes can be planned on the same supply.
