There have been some well documented upheavals to distribution in many industries globally over the last decade as a mix of rapidly growing e-commerce, improved global logistics, rising business costs (i.e. compliance) and moves away from regional retail centres has many reeling with rapid change.
All businesses are conscious of the need to ensure that customer satisfaction levels improve or at least remain the same when changes are made. This at times is difficult, especially when there isincreasing demand on customer service resources, no more so than in technical industries, and consumer expectation of lower product costs. It is part of the reason that a number of ourcompetitors have made the decision to reduce either store numbers, inventory held in NZ or support people. This approach can cause customer frustration and worst of all lead to historically great businesses, valued by customers, closing their doors.It is not the vision that we have at TTL, thisyear we are going to embark on growing our
customer support resources and focus on getting more of our core products on the shelf for overnight delivery, we firmly believe that we can deliver even greater service excellence, good value product and high customer satisfaction and provide to our customers a NZ based world class supplier.
Our customers have a key role to play in this by continuing the growing trend towards on-line ordering, the impact of this is our internal people become more available for your important technical enquiries. This is a win/win, our people are better placed to add value to your business, call waiting time is reduced and we will deliver on-line orders to you freight free.We are committed to providing great service and preserving our business in NZ for a long time to come and we really appreciate your part in this.

PosiStop reduces setup time and increases productivity. PosiStop mounts securely against the chuck face (using three strong magnets), providing a fixed reference surface for workpieces to locate against. Interlocking design coupled with strong magnets holds stop securely in place. PosiStop is available in five different
thicknesses:15, 20, 25, 30 and 35 mm.
The standard width of jaw is 25mm, but can easily be milled or sawcut larger for chucks with wider jaws. Anodised aluminium finish provides good wear-resistance.

The stop pin has a hat plate, which means that ESSET can be used for stops in a slot or groove.Each unit has a working height of 0-150 mm.ESSET can be used as a stabiliser for workpieces which tend to vibrate in the machine.It is practically impossible to wear out ESSET.

At the heart of every SynchroFlex®tool is a patented computer designedflexure that compensates for the minute discrepancies between the machine feed and traverse and the exact thread pitch and hold location. Tap life is increased 100% or more. Often much more!
Within the body of every CST tool is aself-reversing mechanism that eliminates
two machine reversals for each hole tapped and allows the machine to
maintain constant speed throughout the thread cutting operation. Good for the tap,

Firstly be aware that they are many different brands of centres out in the workplace and not all are of the same quality, so this article assumes that whatever brand of centre you’re using is of acceptable quality. Next, we’ll assume that most centre designers have tried to keep pace with today’s higher horsepower machines, faster speeds, more aggressive machining, and high pressure coolants - all of which can limit accuracy and service life of a live centre. Granting these assumptions, premature failure should not be laid at the doorstep of the centre. But neither are you, the users, necessarily at fault. So why do some centres fail prematurely? We have a good idea of some of the reasons why good centres don’t perform as expected.
MISAPPLICATION OF THE CENTREMisapplication is probably the most common cause of premature failure. Selecting the right centre sounds easy because you already know the work piece weight, the machine RPM, the tailstock taper, the required tailstock dimensions, the point style (for adequate tool clearance), and, in most cases, the required centre accuracy. Make sure the centre you select suits all the above criteria.
MISAPPLYING TAILSTOCK FORCEApplying incorrect tailstock force ranks a close second to using the wrong centre for why a centre may fail prematurely. Applying the correct load to the work piece and the centre is not an exact science, however, and sometimes requires guesswork based on the operator’s experience. Too often, operators guess wrong, and we’ve noticed a general tendency toward overloading. When excessive force is applied the axial load limit of the centre bearings is exceeded, inevitably leading to seizure and early failure of the centre. In rare cases, even the machine spindle bearing can be damaged by overloading, resulting in costly down-time for replacement. Conversely, if the tailstock force is too light, the centre will soon slip, chatter, and wobble, galling the shaft centre-hole and damaging the centre’s point. If not shut down soon enough, friction-induced heat can actually “weld” the centre to the work piece. Not good.There’s no simple formula for correct tailstock force, but we can offer some suggestions. For starters, make sure that the centre is easily capable of handling the work piece weight, and employ proper machining practices suitable to the weight of the work piece. For critical applications, you might require an Analog Force Gauge which can measure the precise load in pounds of force.
WORN QUILL TAPEROver time, the tailstock quill, which holds the centre, may become out-of-round, and will loosen its grip on the centre taper. This naturally induces a wobbling of the centre, producing chatter, which greatly reduces accuracy and leads to unacceptable parts. Quill wear can be easily checked. Apply Bearing Blue to the centre taper and insert into the quill. Upon removal, if the bluing shows irregularity, or gaps, then the quill taper needs to be repaired.
INSUFFICIENT STIFFNESSAND RIGIDITYBoth the cutting tool and the centre must have sufficient stiffness to avoid deflection under heavier loads. If not, this typically results in chatter, out-of-round parts, and/or tapered parts, which in turn, can double any subsequent grinding time. Be sure that the centre has ample capacity and is not running above 60 or 70 percent of its maximum work piece weight rating. Again, the centre manufacturer can recommend the correct model to avoid premature failure and bad parts.
MISGUIDED LUBRICATION PRACTICESLive centre design can include many types of bearing lubrication depending on the type and severity of the machining operation. Additional lubrication, sometimes in excess, has been applied in a misguided attempt to keep the centre running longer. Don’t do this. Understand that the centre’s original lubrication may be chemically incompatible with other oils and greases, and mixing these incompatible lubrications could cause premature bearing failure.
