Laser Cutting Provides Better Gas Flow

In several development steps with cutting trials, Precitec has increased the flow rate through the cutting nozzle while keeping the cutting gas pressure constant. The KT B CON ceramic part and the nozzles now have no 'hard edges' and have a conical geometry. Thus, the cutting gas pressure can be reduced while giving the same cutting edge quality and the input pressure directly on the processing head can be reduced.

The company said that field tests with the new design have also shown an increased working range for the focal position. Dirt on the focussing lens and the associated focus shift can be detected with the larger process window and increase the operating life of the optics. With CO2 cutting heads without a protective window in particular, this leads to cost advantages.

Autodrill Adds Option To Cutting Machines

Autodrill has enabled a manufacturer of oxyacetylene cutting machines to offer a hole drilling option. Because making small, accurate holes through thicker material is sometimes impossible with a laser unit, the manufacturer researched putting an automatic drill on its machine.

By drilling all the holes with a standard Autodrill machine, smaller holes are now possible through even the thickest materials due to the optional peck drill features available. The customer is also considering placing multiple spindle drill units on a single fixture, to drill many small holes at the same time. Annular cutters with a positive plug ejection system can also be used for some applications.

All the equipment is rated for continuous duty production work. Autodrill offers free application and design assistance during the quote and post-sale process. Free CAD drawings are available for all equipment. A search for Autodrill on Youtube and other video sites turns up a number of example videos.

Kasto Supplies FOM Aluminium Cutting Line

Ideal for small- to medium-volume manufacturers of high-performance aluminium doors and windows, a cutting line from Italian machine builder, FOM, is now available in the UK from Kasto. The LT500 line is available in two versions, with either a fixed or roller-type unloading table, the latter capable of handling cut pieces of 5m and above.

Both models incorporate a cropper and step-in system to feed aluminium bars towards an NC manipulator arm with pneumatic gripper, which then advances the material up to a stop in the cutting area. Horizontal alignment of the bar, which can be up to 7m long, is by a pneumatic stop and magnetic sensor. The aluminium is clamped by manually-adjustable horizontal and vertical vices with jaws that are interchangeable to suit the profile type.

Cutting by the 500mm diameter blade of the single-head mitre saw can be at three fixed angles, 45, 90 or 135 degrees. Electrical adjustment of mitre angle from 30 to 160 degrees is an option. During the cutting process, off-cuts and swarf are removed via an internal chute. A series of blowers aims jets of air at the machining area to keep work surfaces as clear as possible of swarf.

They continue to blow after completion of the cut to finish the table-cleaning process before arrival of the next profile. Cut pieces are transferred onto a moving table with a non-scratch surface, and from there to the offload table. The 3-axis CNC system is connected to a Windows Vista PC, from where cutting order data is downloaded.

The PC has been designed to swivel towards the loading area to allow the operator to see the bar being fed through, or towards the unloading area to make it easier to use an optional labelling device. Procut software is able to create and save cutting lists, import and optimise external lists over a network or from a USB memory stick, manage profile archives containing sections and cutting parameters, and display profiles in DXF format while an order is being cut.

Korloy CBN Inserts Hard-Turn Without Cutting Fluid

Cutwel has released Korloy CBN inserts, which can be used for hard turning with no cutting fluid. Existing or standard ISO toolholders can be used to hold the inserts. Typical materials that are hard-turned are grey cast iron (180-230HB), high-temperature alloys (over 45HRC), sintered alloy, carbide roll and high-speed steel roll.

Grade KB320 is suitable for intermittent and continuous cutting on hardened steel, and Grade KB330 for heavy intermittent cutting on hardened steel. Other grades include Grade KB360 for continuous cutting on cast iron, sintered alloy, heat-resistant alloy and carbide roll, and KB420, for continuous cutting on hardened steel.

Advantages include the following: cycle times and set-ups are generally much shorter on lathes than on grinding machines; CNC lathes are generally recommended for hard turning, but manual lathes can be effective as well; hard turning requires a rigid machine with a rigid toolholder system.

CBN inserts promote faster cycle times, cut cost of machine tool investment, improve accuracy, give high-quality surface finishes, permit higher metal removal rates (two to four times faster than grinding), allow multiple operations in a single chucking, and make wet or dry cutting an option (dry cutting avoids coolant expense and disposal issues). Full technical back-up is offered on insert selection, speeds feeds and recommended depths of cut.
