Drilling machine: which one to choose for wood and metal for a garage or home workshop? Review of 10 popular machines based on reviews

Classification of drilling machines

Drilling equipment is divided into:

1. Vertical drilling – great for use in a small workshop or garage;
2. Single-spindle semi-automatic machines - drilling is done automatically, everything else is done by the operator;
3. Multi-spindle semi-automatic machines - it is possible to process several holes due to the presence of several spindles;
4. Jig boring – necessary for creating holes with strict adherence to the required parameters;
5. Radial drilling - holes can be processed anywhere in the part due to the ability to move the spindle relative to the workpiece;
6. Boring – machining of holes can occur without additional equipment and markings
7. Diamond boring machines – designed for fine boring of holes with a minimum tolerance for cylindricity (3-5 microns);
8. Horizontal drilling and center - used to create deep holes;
9. Various drilling machines are special-purpose machines for specific purposes.

Types of metal-cutting equipment

Depending on their purpose, metal-cutting machines are divided into nine main groups. These include the following devices:

1. lathes - all types of lathe machines (in the marking they are indicated by the number “1”);
2. drilling and boring - machines for performing drilling operations and boring (group “2”);
3. grinding, polishing, finishing - metal-cutting machines for performing finishing, grinding, sharpening and polishing technological operations (group “3”);

• other types of machines for processing metal workpieces: dividing machines, used for monitoring drills and grinding wheels, filing, balancing, leveling and centerless roughing, sawing.

Vertical milling machine is one of the representatives of an extensive milling group

Classification of metal-cutting machines is also carried out according to the following parameters:

• by weight and overall dimensions of the equipment: large, heavy and unique;
• by level of specialization: machines designed for processing workpieces of the same size - special; for parts with different but similar sizes - specialized ones; universal devices that can be used to process parts of any size and shape;
• according to the degree of processing accuracy: increased - P, normal - N, high - B, especially high accuracy - A; There are also machines that can perform particularly precise processing - C, they are also called precision.

Designation

Drilling equipment is divided into models according to the table of metal-cutting machines. Each model is unique and has a corresponding name, consisting of a set of numbers and letters.

The first number indicates belonging to a specific group of machines, 2 – drilling group. The second number indicates the type of machine. The third and fourth digits indicate an important parameter for the machine, that is, the maximum diameter of the hole being machined.

If there is a letter between the first and second numbers, then it indicates the modernization of the original machine. The letter at the end speaks of the creation of a machine different from the original based on the main model.

Let's look at a few examples:

• 2118 – vertical drilling machine, achievable hole diameter – 18 mm.
• 2N118 – vertical drilling machine, achievable hole diameter – 18 mm, modernized;
• 2N118A - vertical drilling machine, achievable hole diameter is 18 mm, the letter A indicates the automation of the machine.

Cost and main manufacturers

Horizontal drilling machines are quite expensive devices. Even for old Soviet models of these devices you will have to pay a tidy sum, but a modern machine with numerical software will cost a fortune. Of course, on the market for used devices you can find high-quality goods at a relatively reasonable price, but purchasing them is quite a risky business.

If we talk about Soviet drilling machines of this type, it is worth noting that although they were produced several decades ago, they still have good production characteristics and a relatively low cost. You can buy such a device for 1-1.5 thousand dollars. Machines in good condition and with a wider range of applications will cost from 2 to 5 thousand dollars.

Drilling machine design

Drilling machines are used for both industrial and domestic purposes. However, the differences between them are not significant. Therefore, it is more advisable to consider what a household drilling machine consists of, since it has smaller dimensions compared to its industrial relative.

The following mandatory components can be distinguished:

• A massive base on which a vertical stand is attached;
• Vertical stand with drill head
• Drilling head, consisting of a spindle assembly and an electric motor with a belt drive;
• The spindle head on which the chuck is located

Modern machining centers

CNC drilling centers have a PU milling unit base. An isolated working area with a unit for changing high-speed tools and an automatic chip removal function with a liquid supply with a cooling mode through the spindle are the main differences of this device. Machining centers are designed for fast processing of high quality, thanks to a variety of tools, different operations and are:

• horizontal;
• vertical.

These machines are capable of operating both automatically and semi-automatically and follow the same operations as drilling and milling machines.

Therefore they boldly:

• drill out;
• countersink;
• milled;
• drill holes;
• cut external threads;
• cut the internal thread.

If the master wishes, these centers can perform the grinding process. The main components of the center are considered to be a multi-position tool changer, which is capable of being controlled by a new generation control unit. The positioned tool system allows for high-precision processing and reduces operation time.

Operations performed

Using drilling equipment you can do everything related to making a hole:

• Drilling is the rough creation of a hole in solid material.
• Reaming is an increase in the diameter of a previously created hole.
• Countersinking is a semi-finish processing of a hole in order to increase its accuracy.
• Reaming is the finishing of a hole that comes after countersinking.
• Countersinking is the creation of recesses for the heads of bolts, screws and rivets.
• Countering is the finishing treatment of the flat bottom of the recess, comes after countersinking.
• Threading – creating a threaded surface.

Tool

A significant number of different tools are offered for a drilling machine.

Drill. Depending on the shape of the hole being made, metal drills are divided into:

• Spiral;
• Conical;
• Crowned
• Stepped

The twist version looks like a classic drill needed to make a cylindrical hole. The cutting part of the tool cuts into the metal, drilling a hole. The working surface has a spiral design designed to remove chips from the hole being created. The shank is used to secure the part in the machine chuck.

Conical drills are very convenient for drilling in one pass; there is no need to create a hole of a smaller diameter for future drilling. However, the use of such a tool requires high machine power.

Core drills are an empty cylinder with serrations along the entire end, forming a “crown”. They are required to create large diameter holes.

Step drills are a great discovery in the world of drilling tools. Its versatility allows you to create holes of different diameters without using other tools.

Countersinks. The principle of operation is similar to that of a drill. The first group serves for intermediate processing, leaving allowance for reaming, while the second group processes the hole completely without the need for subsequent processing.

Sweeps. This tool is classified according to many criteria, but we will only talk about the main types of sweeps.

Cylindrical reamers. Necessary for finishing cylindrical holes.

• Conical reamers. After using such a tool, the hole takes a conical shape.
• Step sweeps. The principle of operation is the same as that of step drills.
• Countersinks. They are divided into cylindrical, conical and end.
• Cylindrical ones form a recess for hardware with an internal hexagonal hole.
• Conical ones create a recess for hardware with countersunk heads
• Face (forging) are necessary for processing the bottom of the recess in order to increase the perpendicularity between the supporting plane and the axis of the hole.

Taps. They consist of a shank and a working part, consisting of a cutting and calibrating fragment. There are grooves for removing chips. When cutting threads, two taps are used, one for rough cutting of threads, the second for finishing.

Jig boring machines

Jig boring machines can produce a wide variety of machining of cylindrical and conical holes. The orientation of the part can change in any plane. You can not only drill, but also bore the surface with cutters, cut not only cylindrical, but also conical threads inside the workpiece space.

At some enterprises, to make holes with high precision, machines are installed in isolated rooms. They constantly maintain a fixed temperature and humidity.

Most often, such requirements are imposed on equipment used in space production. Some chemical industries require increased precision in the execution of work.

Safety precautions

PROHIBITED:

1. Start work without checking for serviceability and grounding;
2. Start work activities without special clothing;
3. Work without safety glasses or headgear.

To avoid injury, follow these guidelines:

1. Overalls should fit snugly to the body;
2. Do not clutter the machine with unnecessary items;
3. Do not use a broken tool;
4. Do not try to stop the chuck during the cutting process;
5. Check the fastening of the drill in the chuck;
6. Wait until the machine stops, after which you can leave the workplace;
7. Under no circumstances should you adjust the part while the machine is running.

Exploitation

To safely operate a metal-cutting machine, you need to follow safety rules and take into account some features:

• Work using protective equipment, glasses, headphones, gloves.
• Check the integrity of the equipment (drills, cutters, cutters, abrasives) before starting the installation.
• Cool the work area. Water or oil can be used for this.
• Clean the structure from metal shavings after work.
• Lubricate moving parts at least 2 times a month.

You cannot work on machines that make extraneous noise, with missing fasteners, or exposed wires.

Metal-cutting machines combine various installations that are used for metal processing. They are divided according to different factors and have certain markings. By learning to read the numbers and letters indicated on the equipment body, you can learn a lot of information without reading the description or technical data sheet.

Tips for choosing

Please note the following points:

• Processed material. There is no need to buy equipment with huge capacities for drilling wood or plastics.
• Machine type. Select the machine according to the processing you need. Why do you need an expensive multi-spindle machine if you need to drill identical small holes?
