Today, the requirements for the accuracy of printed circuit boards increased significantly. Accordingly, the quality of the holes performed should also be higher, and this largely depends on the choice of tools used in production.

Defects often occur when processing printed circuit boards with unreliable drills. And inaccuracies are noticeable only at the final stages of production. Therefore, it is very important to use the drill for high quality printed circuit boards.

Irlen-Engineering offers drills for CNC machines used to drill holes of various diameters and depths in products from metals and their alloys. This tool is intended for industrial use in metalworking industries. Drills for machines are made of high-quality raw materials with the addition of special components that increase their strength and resistance to abrasion. Products retain the sharpness of the cutting edge over the set of multiple drilling cycles.

Assortment of drills for machine tools

This directory partition contains several types of drills for CNC machines sorted by category. For each type of product, the corresponding marking table is shown, in which their main parameters and scope of application are indicated. You can purchase drills of the following categories:

• centering;
• superbound;
• short;
• long;
• super long.

Each of the above categories includes drills for CNC machines, which can be selected in a certain range of diameters, as well as depending on the material being processed.

Centering drills

In this section, drills are offered from fine-grained solid alloy with sharpening angles from 90 to 120 degrees. Such a tool is used to prepare a cone-shaped groove before drilling a hole of a certain depth. Pre-processing the desired point by the centering drill allows you to increase the accuracy of the positioning of the main cutting tool. Due to this, the longer drill will be held in the metal along the desired axis, without deviating the estimated entry point due to vibrations and other factors.

The centering tool in the catalog is universal and is suitable for the processing of all common metals and alloys used in the modern industry. Depending on the production process, the centering drills for CNC machines can be bought with a diameter of 1 to 30 millimeters.

Ultrashort and short drills

Ultrashort drills for metalworking are a tool up to three diameters. The catalog contains a tool for steel processing, non-ferrous metals and various alloys. Depending on the series, the drill data is offered with a diameter of from 1 to 20 millimeters. The tool is mainly used to drill deaf holes under the subsequent cutting of the thread for fasteners.

Short drills for metal for machines can be used to drill deaf, as well as through holes in the blanks of a small thickness. Range of length of short drills - from three to eight diameters. Depending on the material being processed, you can choose a tool with a diameter of 1 to 60 millimeters.

Long and super long drills

This category of CNC drills machines are used to do through holes in products from various metals and their alloys. Long and super-long drills are supplied with a diameter of 1 to 30 millimeters and from 8 to 30d long. The catalog can be familiar with the detailed characteristics of each tool series.

4.4. Cutting tools and devices for drilling and boring machines with CNC. Drills for CNC machines.

Cutting tool.On the boring and boring machines with CNC, various types of cutting tools are used: drills, centers, sweeps, taps, cenks, boring mandrels, etc. Depending on the material of the cutting part, all these tools are divided into high-speed and carbide, depending on the design - For solid and prefabs, depending on the operations performed, the usual and combined.

Spiral high-speed drills May have a cylindrical or conical shank. Spiral high-speed drills with a cylindrical shank are produced short (GOST 4010-77), average (GOST 10902-77) and long (GOST 886-77). And all these drills are with a leash and without a leash. Spiral high-speed drills with a conic shank are produced by supercount (GOST 10903-77) and elongated (GOST 2092-77). Spiral high-speed drills with a cylindrical shank are designed to drill holes with a diameter of 1 to 20 mm, and with a conical shank - more than 5 mm.

Prefabricated pencils Most effective when drilling holes with a diameter of more than 25-30 mm. Compared to standard spiral drills, they have several advantages, the main of which is the lower cost of exploitation per unit length of the hole. This is ensured by using replaceable cutting plate knives, which allow dramatically to reduce the flow rate of high-speed steel.

Fig. 4.8. The design of the team of the first drill.

Unified Collected Personnel Drill (Fig. 4.8) consists of three elements: a replaceable cutting lamellar knife 1, holder 2 and fastening screw 3. In such drills, knives are used for several species: for drilling, for reassurance and cigarette, for centring and formation of chamfer. Various options for the tail part are provided: with internal soil supply, with a cylindrical adjustable shank and with a cone 7/24.

Spiral combined speed drills Used for processing holes for threads. The use of such drills on CNC machines provides combination of drilling and drilling, and in some cases the exception of preliminary centers, thereby reducing the time loss on the auxiliary movements of the machine's working bodies and the tool change. Two types of drills are produced serially - for drilling holes for the thread from M6 to M27 and the chamfer removal (Fig. 4.9, a) and for drilling through holes for the thread from M5 to M24 and drilling under the screw head (Fig. 4.9, b).

Fig. 4.9. Types of spiral combined speed drills:

a - for drilling holes for thread from M6 to M27 and chamfering; B - to drill through holes for the thread from M5 to M24 and drilling under the head head.

The centering drills are available in two types: combined (Fig. 4.10, a) and pen (Fig. 4.10, b). These are presented high demands: so, for example, the fusion of the cutting edges relative to the axis of the body should not exceed 0.02 mm for the drill with a diameter of up to 3 mm and 0.03 mm - for the drill with a diameter of over 3 mm.
