2SS1M tabletop drilling machine. Passport, diagrams, characteristics, description

2ss1m tabletop drilling machine. Purpose and scope

The 2SS1 tabletop drilling machine has been manufactured according to TU 2-024-4345-83 since 1983.
The 2СС1 drilling machine has been manufactured according to TU 2-024-5748706-002-88 since 1988.

The 2СС1 machine is designed for drilling holes and cutting threads in small parts made of cast iron, steel, non-ferrous alloys and non-metallic materials in industrial enterprises, repair and household workshops.

On the 2SS1M machine it is also possible to mill non-metallic materials with end mills.

The spindle of the 2СС1 machine receives 3 rotation speeds from three-stage drive pulleys, which provides free choice of cutting speeds in the range from 600 to 1600 rpm.

The end of the spindle is an external shortened Morse taper KM2, designation B16 according to GOST 9953 (Shortened tool tapers) - shortened cone: D = 15.733 mm.

The shortened cone B16 corresponds to a three-jaw drill chuck of the 10th and 13th standard sizes in accordance with GOST 8522 (Three-jaw drill chucks) with a clamping range of 1..10 mm and 1..13 mm, respectively.

An example of a symbol for a 3-jaw drill chuck, size 10, with a connecting conical hole B16:

Cartridge 10-B16 GOST 8522-79

Cartridge 13-B16 GOST 8522-79

The drilling depth is measured using a dial mounted on the gear shaft. The dial division price is 1 mm of drill feed.

The belt tension design allows you to quickly change the position of the belt on the pulleys to obtain the desired cutting speed.

Using a stand to install the machine makes it possible to drill the ends of long parts, such as shafts.

The 2SS1M drilling machine allows you to perform the following operations:

• drilling
• countersinking
• deployment
• reaming

The spindle speed depends on the diameter of the drill installed in the chuck:

• 1..5 mm - 1600 rpm
• 5..7 mm - 1000 rpm
• 7.5..13 mm - 600 rpm

Drilling holes larger than 6 mm is carried out followed by reaming.

As the hardness of the material being processed increases, the rotation speed should be reduced.

Tool Morse taper shortened

Tool taper - Morse taper is one of the most widely used tool mounts.
It was proposed by Stephen A. Morse around 1864. The Morse taper is divided into eight sizes - from KM0 to KM7 (in English: MT0-MT7, in German: MK0-MK7).

Morse taper standards: GOST 25557 (Tool cones. Main dimensions), ISO 296, DIN 228. Cones made according to inch and metric standards are interchangeable in everything except the shank thread.

For many applications, the length of the Morse cone turned out to be excessive. Therefore, a standard was introduced for nine standard sizes of shortened Morse cones (B7, B10, B12, B16, B18, B22, B24, B32, B45), these dimensions were obtained by removing the thicker part of the cone. The number in the designation of a short cone is the diameter of the thick part of the cone in mm.

Russian standard for shortened cones GOST 9953 Shortened tool cones.

Russian standard for drill chucks GOST 8522 Three-jaw drill chucks.

1. B7 - Morse cone KM0, D = 7.067 mm;
2. B10 - Morse cone KM1, D = 10.094 mm. Cartridge 4-B10 (0.5÷4 mm);
3. B12 - Morse cone KM1, D = 12.065 mm. Cartridge 6-B12 (0.5÷6 mm), Cartridge 8-B12 (1÷8 mm);
4. B16 - Morse cone KM2, D = 15.733 mm. Cartridge 10-B16 (1÷10 mm), Cartridge 13-B16 (1÷13 mm);
5. B18 - Morse cone KM2, D = 17.780 mm. Cartridge 16-B18 (3÷16 mm);
6. B22 - Morse cone KM3, D = 21.793 mm. Cartridge 20-B22 (5÷20 mm);
7. B24 - Morse cone KM3, D = 23.825 mm;
8. B32 - Morse cone KM4, D = 31.267 mm;
9. B45 - Morse cone KM5, D = 44.399 mm.

Where D is the diameter of the cone in the main plane.

Review and description of tabletop drilling machines

Compact tabletop drilling machine designed for small jobs. It is widely used when it is necessary to make a small hole. You can make a homemade unit, but this is not always rational.

Photo of tabletop drilling machine

A tabletop drilling machine allows you to process small cabinet parts with your own hands by:

• Drilling;
• Countersinking;
• Reaming;
• Reaming holes.

If we are talking about a desktop drilling and milling machine, then sharpening becomes an additional feature of the equipment. For fine sharpening, such units are indispensable, since several useful functions are combined in one body.

The machines NS 12, NS 12a, JDP 10l, 2n106p, 2ss1m, Einhell products, GS2116k, Bosch pbd 40, AC2116m and many others have gained wide popularity.

When reaming holes, the capabilities of these machines provide drilling with a diameter from 0.2 to 16 millimeters. Some models, in addition to sharpening, are capable of thread cutting.

The design of the unit provides that household devices for working on metal, wood, and polymers are installed on tables. All such machines for drilling, sharpening and other operations are vertically located.

A tabletop drilling and milling machine, as well as its analogues, can be used in the arrangement of:

• Home workshops;
• Repair rooms;
• Vocational schools as training equipment;
• Small metalworking enterprises.

Specifications

DIY desktop drilling machine

Working with your own hands with vertically positioned machines designed for drilling, sharpening, and reaming holes is quite simple. Household models are great for home use. Their engine provides the necessary power and rotation speed.

In order to correctly select a vertical drilling unit for sharpening and other operations, you need to pay attention to several of its main characteristics.

Most models of vertical drilling machines have a belt on 3-5 speed pulleys. With its help, the rotation speed of the machine spindle is adjusted. This plays a vital role in achieving the desired result of processing the material. At the same time, the most significant characteristics when purchasing a compact vertical drilling machine for reaming, countersinking and sharpening are:

1. Maximum permissible spindle movement. This determines what workpieces a small vertical drilling machine can process and how comfortable it will be to work with it.
2. Drive power. The engine of a wood cutting machine may be less powerful than the engine of a metal cutting machine. Household models are the least powerful. But if you plan to work on wood, plastic, or metal, it is advisable to choose an engine with a power reserve.
3. Distance between table and spindle. Determines the maximum permissible dimensions of processed workpieces. For sharpening, working on metal and wood, this plays a significant role, so try to make the right decision with your own hands.
4. Table dimensions. There are both mini vertical drilling machines and simply compact ones. The first ones are used for processing the smallest parts, microcircuits. Household compact ones allow you to work with larger products. Hence the difference in table sizes. Although some people make the table with their own hands. A homemade unit is completely adaptable to the requirements of a particular master. Therefore, a homemade machine has every right to exist.

Try to build a homemade unit with your own hands, buy an inexpensive Soviet machine, or buy household factory models? The choice is entirely yours. Let's just say that building a homemade machine with your own hands is not an easy task. That’s why most people choose ready-made household devices for working on metal, plastic, wood, etc.

Is it worth building a homemade machine? If you have no experience, it will be impossible to make a homemade unit. Plus, a homemade device cannot meet all safety requirements and operating nuances. Therefore, if the choice is homemade or factory made, we recommend choosing the second option.

Machine setup and operating mode

Setting up for drilling is done as follows:

• lift the quill with spindle 1 (Fig. 5) and with drill 3 fixed in chuck 2 to its highest position
• Set the movable table 5 in height so that the gap between the upper plane of the workpiece 4 and the end of the drill is at least 5 mm
• When drilling holes to a given depth, it is necessary to use a dial mounted on the gear shaft.
• Move the drill to the surface of the workpiece, then, turning the dial counterclockwise (looked from the dial side), align the “zero” division of the dial with the mark on the machine.
• The price of one division of the dial is equal to 1 mm of drill feed.

The required rotation speed of the tool is adjusted by rearranging the drive belt.

The following rotation speed is recommended depending on the drill diameter:

• Drill Ø up to 5 mm – 1600 rpm
• Drill Ø 5—7.5 mm — 1000 rpm
• Drill Ø 7.5-13 mm - 600 rpm

Drilling holes with a diameter greater than 6 mm should be carried out by subsequent drilling.

As the hardness of the material being processed increases, the rotation speed should be reduced.

When drilling large parts installed directly on the floor or stand 2 (Fig. 6), it is necessary to rotate the traverse 1 by 90°.

Having secured the end mill 2 in the chuck 1 (Fig. 2) and the stop 3 on the movable table 5, you can mill a groove in a wooden block 4 by manually feeding the block along the stop onto the cutter. The quill must be locked with bolt 9 (Fig. 2).

Attention! The duration of continuous operation of the machine under load is no more than 30 minutes. Resumption of work on the machine is possible when the electric motor cools down to a temperature of 50° C.
