Which eccentric press is better – presses comparison

Presses are used in different industries such as light industry, metallurgy, chemical industry and other kinds of metal working industry for such operations as pressing, punching, cutting, straightening, assembly and disassembly and a lot of other operations. Mainly all presses are divided into two groups: mechanical – eccentric presess and hydraulic presses. They in turn also are divided into some groups. In this article we will talk about mechanical presses, we will consider four different presses and will decide which one is better.

Which turret punching machine you need to buy

What is turret punching machine and what is it destination? It is a machine destined for punching holes in the workpieces with variable shapes, sizes and different intervals between the perforations as well as for cutting large round holes, square holes, oblong holes and holes with other shapes using different tools. This machine is suitable for industries connected with electronic measuring instruments, computers, electrical appliances and for other industries where appropriate small-scale production of various types of sheet metal. There are a lot of types of these machines, which differ from each other by technical parameters and equipment. But which machine will be the best to buy? In this article we will compare three turret punching machines of different manufacturers and with different features and will try to choose the best one.

Tool Grinder JUNGNER US 450

Tool grinder JUNGNER US 450 (figure 1 and 2) was produce in 1992 by well-known Swedish company Jungner which was established in 1910 and become a leading manufacturer of tool grinding machines. Machines of this company are characterized by high quality, comfortable design and high performance. Our tool grinder is not the exception. It is destined for sharpening milling cutters, drills, knives, rollers and other tools. It is an extremely versatile machine used to perform a variety of grinding operations with surface, cylindrical, or complex shapes details.

Tool grinder Tacchella 4AM

The tool grinder Tacchella 4AM (figure 1) was manufactured in 1984 by Jotes firm. Tacchella Machine is an Italian manufacturer of tool sharpening machines, universal grinding machines, broaching machines and cylindrical grinding machines. They produce machines of very high quality for more than 80 years. Tacchella is one of the best in the world in his field of activity. The company has approximately 50 departments in the entire world.

Box column drilling machines comparison

Talking about box column drilling machines first of all we can notice that they are used for drilling, reaming and dredging. But those machines can do another operation such as milling, taping or boring. Drilling machines, especially box column drilling machines are used mainly is small-scale production but some modifications of those machines also uses in mass production. We have two box column drilling machines that were produced by different companies and have different technical parameters. We will have to compare these machines. Our first drilling machine is Stankoimport 2H135 (Figure 1 and 2).

Jig borers comparison

We know that drilling machines is used basically for drilling blind and through holes in solid material but they also used for boring, countersinking, reaming, tapping and cutting discs from sheet material. For operations like that we use drills, countersinks, reamers, taps and other tools. There are different types of these machines that perform different operations and functions. We have box column drilling machines, column drilling machines, radial drilling machines, bench drilling machines, tapping machines and jig borers. In this article we will talk about last one and will compare two machines produced by different producer.
Our machines to comparing are STANKOIMPORT 2B440A (Figure 1) and WMW BKOE 400×630 2PA (Figure 2). Both producers are well known and they make competitive machines. WMW BKOE is a popular Germany producer and STANKOIMPORT is an USSR (now Russian) producer which has great reputation in the world.

Eccentric presses – slider

The operating principle of the eccentric press is to change the rotary motion into linear motion – reciprocating. The electric motor drives the flywheel and at the time of the clutch, flywheel power through the crankshaft is transmitted to the slider (here turns into rotary motion into linear motion). Reciprocating slider moves, and the tool cuts or is pressed Sheet Metal.

CNC Milling machines – body types

We have two main kinematic systems CNC routers. One of them is a type of Bed-Type Milling Machines, and the second is the knee type. Main parameter differs both types is load the table. Due to the construction of milling machines carry heavier loads Bed Type and thus are applied to the processing of heavier and larger overall dimensions of machined workpieces.
