Slitting line is a large capital investment item. For precise slitting, you need a good slitting line, Slitter tooling quality is as important. Without good quality tooling you can't get good results even if slitting line is very precise ...

We, at Dee Tee are engaged in the manufacturing of tooling for various metal processing industries since 1975. While meeting the stringent quality and tough application requirements of our reputed customers, we have acquired sufficient expertise and experience...

Technically speaking, the outer diameter of the slitting knife should be kept as large as possible to get more life. Nevertheless, design parameter of slitting line will limit its size for obtaining stable slitting, because when O.D. of knife increases, cutting force increases, outness of knife also increases...

Shimless tooling is modern concept available in market for slitter tooling. By name, it implies that managing slitters without using plastic shims. Plastic shims are soft and compressible. While being used on slitter in a stack, upon tightening by locknut...

Shear Blades and Machine Knives find application in all types of industries dealing with steel/non-ferrous alloys, cellulose, fibre boards, paper & plastic etc. ...

Friction Sawing is particularly advisable when a clean cut is of importance. Dee Tee Friction Saws are designed for high speed cutting. They are manufactured from Chrome-Vanadium(Cr-V) Steel, 1.2235, or Ni-Cr Steel with maximum stability at surface speed of 60-90 meter per second. ...

In our continuous quest for unparallel quality, service and reliability, we turn our cumulative expertise in the field of TUBE, PIPE and SECTION MILL ROLLS. We design and manufacture variety of rolls keeping just one thing in mind ...

SLITTING CLEARANCE: Proper knife clearance minimizes burr, increases knife's life by reducing wear and tear. Italso reduces stress on the machine and improves slit width tolerance. While slitting, knives cut partially ...

The raw material is taken 8/10 mm plus on diameter over final size so that all forging defects on O.D. are machined out. Double Column CNC band saw machine is used for faster and accurate cutting. ..

In any Slitting Line, there is an uncoiler, slitter head and recoiler. After Slitting, many strands come out of the slitter head. These strands are to be coiled separately, neatly so that their edges are protected ...

Flatness is also known as warpage. Flatness means total dial indicator reading while putting slitting cutter on surface plate below dial indicator. Flatness is the maximum variation obtained from surface plate on the upper face of Slitting Cutter.

After strip is formed into round shape, inner fibres of tube come closer and outer fibres fall apart. if such a tube is welded then it will be a very weak welding, as both surfaces of open tube will not be matching...

The most common method of cutting welded steel tubes on tube mill has been by Friction Saw and next by COC Cutters. But these methods are not fast enough and can be used only upto Mill Speed of 75 mts./min. This limits the speed of Tube Mill & hence the capacity...

Shafts are machine members, mostly circular in cross-section, which support the revolving parts of a machine, such as Tube Mill Roll, pulley, gear, fly-wheel, etc. Shaft not only supports a revolving part but also transmits torque. As a result, the shaft is subjected to bending as well as torsional stress...

Chipping off, flaking off, dismembering of a portion of roll from the Roll barrel is known as spalling. Spalling can occur both in work rolls as well as in back up rolls and is usually the end effect of crack generation and propagation. ...

In case of on-line Tube Cutting, one of the most recognised methods is by using three small round cutters which press the tube from three points while the cutting head is rotating around the tube...

Cold Rolling Mill Rolls are used for cold rolling, ferrous and non-ferrous metals in Cold Rolling Mills. They have hardened roll body and their sensitivity to temperature and over heating is extremely high..

20 Hi Mills are unique in feature as they have chockless floating work rolls and a cluster configuration for the back-up bearings. It constitutes of 2 work rolls, 4 intermediate rolls, 2 idler rolls, 4 drive rolls and 8 back up bearings...

एक बार रोल जब complete हो जाता है तो प्रायः बाहर से पूर्णतया सही दीखता है | इसके अंदर की quality को आँखों से देखा नहीं जा सकता | अतः रोल surface या भीतरी defects को जो raw material या heat treatment या ginding के कारण...

The structure of Steel when heated to austenitic temperature (hardening temp.) and cooled rapidly (quenched) gets converted to martensite. The formation of martensite gives wear resistance and increases the hardness of steel. ..

A large range of Alloy/Tool Steels are used for manufacturing DeeTee Tools. These alloy steels have various alloying elements which impart different properties to tools. Selection of a particular alloy steel for a tool depends upon the performance desired from a tool....

Cryogenic treatment is an extension of the standard heating/ quenching / tempering cycle of conventional metallurgical practice...

Levellers are meant for levelling strip. The process of levelling has two purpose. First, to make the surface flat and second, to neutralize hidden internal stresses, causing shape defects i.e. center buckle, edge wave, cross bow etc...

रोल बैरल से रोल की चिपिंग, फ्लेकिंग या एक बढ़ा टुकड़ा निकल आना स्पाउलिंग कहलाता है | स्पाउलिंग, बर्क रोल और बैक-अप रोल दोनों में होते हैं| क्रेक जनरेशन और प्रोपेगेशन का आखिरी परिणाम स्पाउलिंग होता है ...

Once a roll is completed, whatever defect is inside the roll cannot be seen with naked eyes. From outside, roll appears to be normal...
