T-DRILL TCC-50 automatic tube cutting machine
The typical application areas of TCC-50 automatic cut-off machine are
aumotive industry and heat exchanger industry (solar).
TCC-50 cuts tubing from either straight lengths from the Rackloader (see
TCC-50 RL) or coiled tube from a Double Coil Holder. Here we concentrate on
coiled tubing only.
The tube is pulled into the TCC-50 automatically by
a pneumatically operated hitch feed mechanism. Max. stroke length is 710 mm. The
maximum cut length, 10650 mm, can be achieved with multifeed operation. Standard
multifeed is 15 strokes.
The tube is fed to the desired length and clamped on both sides of the
cutting head, which rotates around the tube. There are special back-up rollers
which support the tube, when the cutter penetrates the sidewall and performs
There are three different cutting methods available:
The Pull-apart method is the most advanced cut-off method: first the cutting disk penetrates the tube wall by approximately 90%. The cut-length is then separated by pulling it apart. This eliminates the I.D. reduction that could occur, if the blade was to completely cut through the tube wall.
With the Pull-apart method secondary operations such as endforming, and mandrel bending, are easier to carry out as the cut quality is usually good enough to allow these operations without having to deburr.
The Cut & Break method is possible when tube piece length is under 70 mm. The blade is set to penetrate approximately 95 % through the tube wall, at which point the clamping fixture breaks the tube sideways. This method is only available on the T-DRILL TCC-50 Cutting Machine.
The throught cut method is the most fundamental method of cutting tubes by using rotary cutting disks. This method is used for cut lengths of 30 mm and longer by basic equipments. This method can be used in cases where some reduction in the internal diameter is acceptable.
The machine is equipped with a predetermining batch counter, which turns the
system off after the preset number of cuts has been completed.
T-DRILL standard decoiling system includes double decoiler and tension unit:
