Punch machine

A punching machine works like a hole punch for paper. The punch presses the paper against the support of the hole punch and finally into a round opening. The scrap from the punching collects in the hole punch container.

Punching works exactly the same way: the sheet is positioned between the punch and the die. The punch moves downward and plunges into the die. The edges of the punch and the die move past each other in parallel, cutting the sheet. Observed in detail, the punching process proceeds in four phases. When the punch touches the sheet, the sheet is deformed. Then it is cut. Finally, the tension within the material is so great that the sheet breaks along the contour of the cut. The cut-out piece of sheet - the so-called punching slug - is ejected downward. When the punch travels upward again, it can happen that it pulls the sheet along. In that case, the stripper releases the sheet from the punch.

The higher the fraction of cut on the sheet edge, the better the edge quality. For precise fits, for example, preliminary holes are punched and then the final diameter is punched out with a slightly larger tool. The fraction of cut along such an edge is then as high as 100%.

Axial Forming

Felss has redefined what can be done in terms of industrial manufacture of splines.

In short: The axial forming technology offers improved possibilities to form high quality internal and external splines made chipless, fast, reliable, and cost-effective.

In more details, the special low-frequency modulated axial forming process ensures the net shape forming of splines to the highest quality (IT5 quality classification) even after the part has been hardened, and on a very thin tube wall. This part quality is given by the combination of the forming process, the shape of the die design and the high-stiffness tool system that also offers unique possibilities for fine adjustment of the carbide splining die. The tool system can actively control the splined part diameter with +/- 0.03 mm (measured as over-pin diameter).

The Felss axial forming process is largely independent of the pressure angle of the die. This unique feature means that one can design the spline profile more freely than would be possible with competing technologies, and without giving in on the general die performance and service life.

Both external and internal splines can be formed by the Felss axial forming machine technology. Here it is very important to mention that internal spline forming in blind holes is offered as a standard solution in the same machine and just with one clamping. Because of the special tool exchange system, one can also make for example three different spline profiles on the same part in the same clamping.

Another key benefit of the axial forming process is the higher strength of the teeth compared to what can be obtained with conventional metal cutting technologies. Forming does not break the grain structure of the work piece, and this significantly contributes to the static and dynamic strength of the splined profile.

The repeatability and predictability of the axial forming process is also a very important benefit to mention. Of course, depending on the actual part and work piece material, the die will form approx. 1.6 km splines.

The machine concept is flexible. It is within certain limitations possible to add a tool exchange system, or add a second NC axis for internal splining from the bottom side, if required for new part production.

Shearing Machine

A shearing machine is disclosed which comprises a work table, a pair of upper and lower blades for cutting a work-sheet, and a feeder for feeding the work-sheet onto the work table for cutting by the blades. A scrap receiver receives scrap cut from the work-sheet by the blades and a scrap remover positioned in front of the blades clamps and holds a piece of scrap from the work-sheet and transports the scrap to the scrap receiver. The scrap remover is movable in a horizontal plane above the work table.Shearing Machine

Grinding Machine

A grinding machine is a machine tool used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.

The grinding machine consists of a power driven grinding wheel spinning at the required speed (which is determined by the wheel’s diameter and manufacturer’s rating, usually by a formula) and a bed with a fixture to guide and hold the work-piece. The grinding head can be controlled to travel across a fixed work piece or the workpiece can be moved whilst the grind head stays in a fixed position. Very fine control of the grinding head or tables position is possible using a vernier calibrated hand wheel, or using the features of numerical controls.

Grinding machines remove material from the workpiece by abrasion, which can generate substantial amounts of heat; they therefore incorporate a coolant to cool the workpiece so that it does not overheat and go outside its tolerance. The coolant also benefits the machinist as the heat generated may cause burns in some cases. In very high-precision grinding machines (most cylindrical and surface grinders) the final grinding stages are usually set up so that they remove about 200nm (less than 1/100000 in) per pass - this generates so little heat that even with no coolant, the temperature rise is negligible.

Band Saw Machine

A bandsaw is a power tool which uses a blade consisting of a continuous band of metal with teeth along one edge to cut various workpieces. The band usually rides on two wheels rotating in the same plane, although some small bandsaws have three wheels. The saw may be powered by wind, water, steam, electrical motor or animal power. Bandsawing produces uniform cutting action as a result of an evenly distributed tooth load. Bandsaws are used for woodworking, metalworking, or for cutting a variety of other materials, and are particularly useful for cutting irregular or curved shapes, but can also be used to produce straight cuts. The radius of a curve that can be cut on a particular saw is determined by the width of the band and its lateral flexibility.

Shaping Machine

The shaping machine is used to machine flat metal surfaces especially where a large amount of metal has to be removed. Other machines such as milling machines are much more expensive and are more suited to removing smaller amounts of metal, very accurately.

The reciprocating motion of the mechanism inside the shaping machine can be seen in the diagram. As the disc rotates the top of the machine moves forwards and backwards, pushing a cutting tool. The cutting tool removes the metal from work which is carefully bolted down.

The shaping machine is a simple and yet extremely effective machine. It is used to remove material, usually metals such as steel or aluminium, to produce a flat surface. However, it can also be used to manufacture gears such as rack and pinion systems and other complex shapes. Inside its shell/casing is a crank and slider mechanism that pushes the cutting tool forward and returns it to its original position. This motion is continuous.

Drilling Machine

Drilling is one of the most effective and common activities often observed in metal processing industry or manufacturing industry. These tools are used for preparing holes of prescribed diameter and surface finish over the surfaces. The drill bit and power change according to the nature of operations and the surface over which hole is to be drilled.

Suppose you need to drill a hole in your bathroom in the ceramic tiles for hanging a towel holder, you need to select the drill which should be able to make a hole without damaging or affecting the tile. Likewise you may also need to create a hole in the kitchen. The accuracy and finishing of the hole also depends a lot on the skill operator.

While selecting a drilling bit, one should consider the following points. The very first thing is that the torque of the machine you are thinking of. The torque is the factor which will enable you to determine other features of a drill bit. The drill with torque of about 400 to 500 per minute will be best for all your light tasks of the home.

If you need to make a hole in concrete or in brick or any other solid thing then you may need a heavy duty drill as light weight drills will not serve the purpose effectively.

These are also available in several types such as electric, hand operated and battery operated. Nearly all of the drilling machines have changeable drill bits so that you would be able to make hole of desired size.

Depending upon the nature of the job drill machine should be selected, the portable and light weight machine can be used which is either powered by electricity or battery. The best choice is to go for battery powered drilling machine which would help you with all the drilling applications.

The battery drills are available in several capacities such as 18 to 24 volts, 14 to 14. 4 volts and from 6 to 12 volts. If you are using the machine with higher voltage, then the batteries will last long and generate greater power. Hence according to the job they should be selected.

Another thing which should be considered while purchasing a drilling device is the brand. If you have selected a branded or reputed drill, then you will be assured of its performance and efficiency. Most of the leading brands of the market are a bit costly but this factor is compensated by their performance. The leading brands of the market include Black & Decker, DeWalt, Hitachi, Ridgid and many more are meant for meeting every drilling requirement of your job.

These are available with some additional features such as they come with smart chargers, some of the drills come with flashlight but if you are going for these features, it will certainly add to the cost of the machine.

The cost of the drilling machine is another concern and varies according to the voltage and power out of the device. These devices should be selected from the specialist drill bit supplier so that in case of any discrepancies, the problem should be resolved immediately.
