IMAO Fixtureworks, a manufacturer and supplier of workholding components, has introduce a new mechanical zero-point system, Flex Zero, for clamping and precision locating in a single operation.

With one tightening operation on the side of the base, four-point clamping is achieved BTA deep hole drilling inserts by two jaws. The jaws locate and clamp the pins for precise and fast fixture changes, which is said to reduce machine downtime during fixture change operations. The compact Flex Locator Bases are available in 150 mm and 240mm sizes with +/- 0.005 mm repeatability and 2,700 lbs of clamping force.

Designed for quick change of pallets, workpieces and vises in five-axis and vertical machining centers, and the strong clamping forces enable heavy-duty machining. With the pull clamp design, the clamping pins are attached to the underside of the fixture plate, which IMAO Fixtureworks says maximizes space on the fixture plate for multiple workpieces.

IMAO Fixtureworks manufactures and supplies a wide range of industrial products that range from modular fixturing components and workholding devices, including clamps, workholding fast feed milling inserts gripper inserts, supports and locators, to standard machine elements, including pins, material handling rollers and bumpers, fasteners, adjustable handles, cam levers and more.

Index’s Traub TNL18-7B sliding/fixed headstock automatic lathe features seven linear axes and an additional B axis for challenging machining tasks. The extra B axis in the upper tool carrier, which can pivot 100 degrees, enables complex parts and complicated contour elements to be machined at virtually any angular position. These parts also require additional operations such as milling, drilling, lateral drilling and threading. 

According to the company, parallel main-spindle operations previously required angled toolholders with “normal” turret positioning—now Carbide Grooving Inserts the turret simply pivots. The eight-position turret with a double-driven toolholder per position provides additional flexibility.

Tool-turret indexing is carried out by an NC rotary axis without a mechanical lock, enabling free angle positioning of the turret. All turret stations can be equipped with fixed or live toolholders, and the number of tools in the machine can be increased to as many as 54 tool stations through dual- and multi-toolholders.

The lathe also features a compact shank system capable of high-precision toolholder mounting in the turret. Toolholders are seated deeper in the turret for less leverage effect and increased stiffness. For live toolholders, the large shank diameter enables insertion of roller bearings with large diameters. A quick-change system enables fast tool change without removing the toolholder. The compact shank system increases tool life and helps improve surface quality.

Designed for ease of conversion between sliding-headstock to fixed-headstock mode and vice versa, the headstock’s long CNC Inserts Z-travel distance ensures proper positioning of the main spindle, either for sliding headstock turning or fixed headstock turning. The main spindle is equipped with a C axis and delivers high torque to achieve large cutting volumes.

Men's Tungsten Rings

Once upon a time, choosing a wedding ring - especially a man's wedding ring - was a relatively TNMG Insert straightforward task; tradition stated that gold was the metal and the style was classically plain. The only difference between a man's and a woman's wedding ring was the width and/or the thickness, leaving us plenty of time to ponder and puzzle over all the other necessaries.

Why tungsten?

Although gold is still the traditional choice of many engaged couples, a lot of men are turning towards a wedding ring made from one of the newer, tougher, more durable materials that have arrived on the scene. More and more in this age of high tech materials and technology, modern day jewellery is pushing the boundaries of the traditional norm - enriching the range and style of products on offer.

Men's wedding rings - Welcome to the 21st century

Men's tungsten wedding rings fall nicely into this category. The tradition lives on, but on the 21st century man's terms. Tungsten carbide ticks all the boxes for those discerning men who favour something just a bit out of the ordinary, yet stylish and able to stand up to a sometimes hard and hectic life style. Those boxes include:

• There is no other ring metal more wear resistant - anywhere
• Tungsten is extremely hard, it's about ten times harder than 18ct gold, and is not far behind a diamond for toughness
• Tungsten rings are difficult to scratch and will not bend or lose their shape
• Tungsten rings have a permanently polished or matt appearance and require little cleaning
• Tungsten is a lot cheaper than most other quality jewellery metals
• Men's tungsten wedding rings are made in a large range of styles, and a variety of colour tones
• Tungsten sits well alongside gold and silver, each complementing the other

Tungsten wedding rings - Quality is important

Tungsten carbide rings are alloyed with a small amount of cobalt in order to more easily shape and form the wedding band. Many people are wary of cobalt but its use in jewellery is regulated by the EU. Good quality tungsten carbide wedding bands are officially classed as cobalt free because they contain such minimal amounts of cobalt and conform to EU guidelines.

Men's tungsten wedding rings - A tough choice!

Men's tungsten wedding rings may be thought of as unconventional, but are certainly not an indication of compromise. Individual styles, colours and designs exist which are hard to equal. Inlaid precious metals are particularly attractive and are further enhanced when combined with the complementing finishes of matt and polished effect. Another elegant addition is the inlaid cubic zirconia which is slightly harder than most semi-precious natural gems, giving the ring a very stylish look. Men's tungsten wedding rings may be laser engraved with a design of your VNMG Insert choice, sentiments of special meaning between you and your loved one, or a combination of both.

Styles and Designs - It really is up to you

We are all individual; tastes and preferences vary from one person to another. Fortunately, the range of men's tungsten wedding rings available covers all personalities and styles; from understated, simple bands to beautifully engraved and intricately worked designs. Men's tungsten wedding rings sit well with formal wear or work-wear, through busy lifestyles or sporting activities. With very little maintenance and after care, they will last a lifetime - looking as good in the years to come as the day you first slipped it on your finger.
