Tangi-Flow Products Limited (formerly L & T I Brock) was founded in 1946 as a precision engineering company, based in Coventry, England. Specializing in industrial sewing machine components and then diversifying into the design, manufacturing and supply of tooling for the engineering industry and latterly sub-contract machining.

Tangi-Flow roller box turning is the most effective means of producing accurate, true and parallel diameters with maximum repeatability. Ideally suited to any manual, multi-spindle or CNC lathe, the unique auto-retract action enables the roller box to be retracted in cycle whilst leaving no return mark on the work piece. Surface finishes as low as 4 CLA have been achieved dependant on machine condition and material. The range of Tangi-Flow roller boxes cover capacities from 1.3mm to 51mm diameter. This, coupled with the different grades and styles of insert available, ensures a truly flexible tool.
Tangi-Flow's claims of durability and quality are not simply optimistic assurances. The whole product range have undergone the most stringent form of testing for many years producing high quality products for the most demanding judge... the end user. See all rollerboxes »
The smallest rollerbox in the range, but still offering the following facilities:- Auto-retraction, integral tipholder capable of holding indexable inserts with a variety of cutting geometrics, micro-adjustment of size, and a range of metric and imperial shank sizes.
Slightly larger rollerbox with more capacity, but offering the same facilities of auto-retraction integral tipholder taking triangular or rhomboidal inserts with a variety of cutting geometrics, microadjustment of size, and a range of metric and imperial shank sizes. Suitable for small diameter turning on CNC lathes.
The most popular and versatile mid-range rollerbox offering integral tipholders to suit both the triangular or rhomboidal shaped indexable inserts, along with auto-retraction, micro-adjustment of size, and a range of metric and imperial shank sizes.
These roller boxes are manufactured to a modular construction where the main body remains constant. Various back plates are available, not only to suit the recommendations shown. Back plates and shanks can be supplied to suit a wide variety of machines including CNC lathes, etc., including Wickman Type Centre Block Fitting. The length of turn can also be modified to suit your requirements.
A smaller version of AR/T5-M – again manufactured to a modular construction. The box can be supplied with either shank mounting or flange fitting to suit a variety of capstans, autos and CNC machines, also Wickman Type Centre Block Stations are available.
Flange mounted hand or air retracted rollerboxes, especially suited to producing a square shoulder with a good quality turned face on a component. Needle roller assemblies and a robust construction allow deep cuts to be taken. Used on hand operated machines or where air is available to the turret.
Spares for Type AR/T2, Type AR/T3, AR/AM-1 AR/A2-M AR/A3-M, and Brown & Sharpe Type.
Plain Carbon Sheets, Alloyed Steels, Stainless Steels, Chipstream Insert, Chipbreaker Insert , Pos. Insert, & Alternative Radii.
Rotary broaching, also known as wobble broaching, is a fast and accurate method for producing internal and external forms in the end of the work piece. The broaching tool holder can be used on any CNC lathe, manual lathe, multi-spindle lathe, milling or drilling machine.
The holder has an internal live spindle; the cutting tool is mounted in the spindle. Although the holder is mounted stationary the spindle and the cutting tool are driven by work piece rotation.
Whilst rotating with the work piece the end cutting broach tools pressure and contacting points are continually changing contact points on the work piece (a wobbling action hence the term wobble broaching) this enables broached forms to be easily produced. See all broach holders »
A broaching head designed primarily to produce hexagonal holes without stopping the spindle. This is the smallest of the range designed to suit the smaller auto or CNC lathe – available in 5/8″ or 16mm shanks.
This head is designed primarily for producing hexagonal holes. A micro screw is provided to set the cutting bit on the machine centre line. The inner shaft is mounted on sealed ball races for precision and long life. R.H. and L.H. rotation is possible to produce a component. The cutting bits can be rapidly replaced and are available in a range of both metric and imperial sizes. Various shank sizes are available.
A larger version of Code 275 but with increased capacity. All technical features remain the same. Various shank sizes are available.
The external broaching has been developed to produce primarily hexagonal forms on turned parts during the turning cycle on capstans, autos, CNC lathes, etc. Recommended feed rate 0.0015″ – 0.002″ per revolution. Spindle speed 885 – 1500 rpm pre-turn bar by 0.010″ – 0.015″ below A/C dimension minimum. Chamfer to A/F dia minimum. At present for use on mechanical feed type machines only. Depending on material and work holding facilities, designed to produce 3mm – 16mm (1/8″ – 5/8″) A/F hexagon with length of flats 1.5 X A/F max. It is also possible to produce squares with limited application. The external broaching head complements the internal head and is available with various shank diameters including VDI. For further information please contact our sales office.
Internal Capacity 1.5mm-10mm (0.05″-3/8″) This universal model offers the versatility of being both an internal and external head, easily converted from one to the other with the exchange of operating shafts codes 1602 and 1612. Various shank sizes available.
