Our company is eager to assist in issuing Technical Passports for broaching machines as per Russian and other EAEU countries’ requirements.
Our engineering company ‘Intech GmbH’ LLC (ООО «Интех ГмбХ»), collaborates with several Russian design institutes in various industrial segments, which allows us to conduct preliminary design as well as subsequent design works according to the standards, construction rules and regulations that are applicable in Russia and other CIS countries. It also enables us to include your broaching machines into the future projects.
The Company has its own logistics department that can provide packing service, handling as well as the most efficient and cost effective mode of transportation of the goods (incl. over dimensional and overweight goods). The goods can be delivered on DAP or DDP-customer’s warehouse basis in full compliance with all the relevant regulations and requirements that are applicable on the Russian market.
Our company has its own certified specialists who will carry out installation supervision and commissioning of the delivered equipment, as well as further guarantee and post-guarantee maintenance of broaching machines. They will also provide necessary training and guidance for the customer’s personnel.
A process, in which the surface is treated by broaches that have a series of cutting edges along their length, is called broaching. When the broach moves relative to a treated part each tooth removes a layer of metal. It is caused by the fact that the dimensions of the teeth increase. Broaches, which have the teeth with gradually increasing height, ranging from tooth to tooth along the length of the entire instrument, are called common broaches.
If some of the broach teeth have the same height but different widths, they are called progressive broaches. The metal cut does not occur throughout the width of the surface, but with narrow strips removing thick chipping (0.4 - 0.8 mm per tooth), which is a feature of treatment with such broaches. Progressive broaching is also characterized by removal of metal layer with each tooth but only from some part of the treated surface. In this case last teeth remove thin layers over the perimeter of the treated surface. Both conventional and progressive broaches have the last few teeth which are calibrating.
These operations are used to treat many surfaces (internal and external) and holes of Ø 6 - 100 mm (round and shaped).
Types of treatment and tools, applied in broaching machines
Broaching has the following advantages:
There are also disadvantages that restrict the use of this process:
The most widely spread method of broaching is machining of already drilled or bored holes. The method consists of the following steps:
There is a gradual increase in the height of the teeth in the cutting part: from the shank to the drawing part. The increase depends on the material to be processed and the size of the hole to be broached. The approximate increase is considered to be 0.01 - 0.2 mm.
Typically, cutting and finishing parts of the broach are made of high speed steel. Broaching of untreated rough surfaces can be difficult due to significant variations in the shape and size of the surfaces. Here, one will need a progressive broach cutting.
Cutting speed during broaching is a speed of broach motion. It usually depends on the material to be processed and nature of the surface to be treated:
V = C·K / Tx·Sy, m/min;
Where С is a condition load effect factor;
Т is broaching stability (time of cutting in minutes);
S is broaching feed (for 1 tooth in mm);
К is a broach material factor;
Power during broaching:
Ne = P·V/60·102, kW;
Where V is cutting speed (m/min);
P is cutting power calculated according to the formula:
P = C1·S0.85·d·z, kg;
Where C1 is a treated material factor;
S is broaching feed (for 1 tooth in mm);
d is a broach Ø, mm;
z is a number of simultaneously working teeth of the broach.
The following types of broaching machines exist:
In first 4 types of machines, the broaches move straightforward, they use hydraulic driver. Horizontal broaching machines are considered to be the most versatile, they are widely used in any industries and are designed to handle the holes. These machines have possibility to handle external surfaces by the way of broaching. The base of the machine contains hydraulic cylinder, which piston rod drives the slide. The broach connects the slider from time to time. One can check oil pressure generated in the cylinder using the pressure gauge.
It is more convenient to carry out the processing of external surfaces using vertical broaching machines. They have increased resistance due to slides resting on the base of the machine. Broaching method helps in these cases to remove allowances up to 4 - 5 mm. The majority of broaching machines for broaching of external surfaces operates in semiautomatic mode (vertical broaching machines), an operator only puts a part to be treated and then removes a processed part.
If it is required to make a few flat broaches sequentially, one can use horizontal broaching machines with a revolving device for this purpose. These machines have broaches that are pushed in turns into a processed billet from the rotary drum while automatically connecting with the slider at the same time. In the reverse movement of the slide, the broach goes back to its cell. When the broach returns to its place in the drum, the table goes back to its initial position. When the drum is rotated to a new position, the next broach starts to work.
In the mass production of small parts, the advantage is given to the continuous broaching, which is performed on the rotary-table- or barreled broaching machines.
