Do you need a drill? -part 3

Automatic drilling machine technical parameters
Processing materials:various metal materials such as stainless steel, metal, copper, etc.
Machining accuracy: +-0.01mm, the free speed is 500mm/s
Processing product size: 2-40mm
Control system: six-axis linkage control system
Voltage: 220V
Power: 350W
Frequency: 50HZ
Air pressure: 6-8kg/cm;
Grounding: <4Ω
Dimensions: 1600mm*700mm*1300mm (L*W*H)

Precautions
1. Select the appropriate carbide drill bits or drill according to the material being drilled. 2. Adjust the appropriate speed according to the material being drilled. If the speed is too fast, the bit will heat up and the low melting point material will soften. If the speed is too slow, the soft material will stick. 3. Determine the number of passes of the drill according to the depth of the hole drilled and the hole diameter. 4. The drilling machine is a high-speed rotary feed, need to pay attention to safety protection. 5. Pay attention to ensure the sharpness of the drill bit, you need to grind the drill bit regularly or replace the drill bit. 6. Regularly refueling the drill shaft.

Operating procedure
In order to make better use of existing mechanized equipment, the performance of mechanized equipment is improved to play its optimal role. It has prompted our mine staff to take the level of operation of mechanized equipment to a higher level, and specially formulated drilling machine operating procedures.

Preparation before starting up
1. Carefully check that the parts of the drilling machine are complete. 2. Is the screw loose? 3. Whether the lubricating oil meets the required position. 4. Control buttons are flexible and reliable. 5. The drill pipe and drill bit are damaged. 6. Holes frame with or without breakage. 7. Whether the spray facility is in place.

Normal boot
1. Drill the machine for 1 to 2 minutes, listen carefully for abnormal noises. 2. Slowly blow your eyes at low speed. 3. The low-speed gear has no abnormality and there is no rubric in the coal seam to adjust the eye speed. If the coal seam always contains the meteorite and the hardness of the rock is large, it can only be used in the low-speed gear.

Do you need a drill? -part 2

The purpose of the rock drilling and digging project is different from that of the construction object, so there are many types of drilling rigs. Drilling rigs can be classified according to their purposes, such as core drilling rigs, oil drilling rigs, hydrogeological surveys and water well drilling rigs, engineering geological exploration drilling rigs, tunnel rigs, and engineering construction rigs. The drilling rig can be divided into four categories according to the drilling method:
(1) Impact drilling rig: wire rope impact type, drill pipe impact drilling rig.
(2) Rotary drilling rig: vertical shaft type--handle feed type, spiral differential feed type, hydraulic feed type drilling rig; rotary type--steel rope plus decompression type, hydraulic cylinder plus decompression type drilling rig; Gyrator - full hydraulic power head, mechanical power head drill.
(3) Vibration drilling rig.
(4) Compound drilling rig: drilling rig that combines functions such as vibration, impact, rotation and static pressure in different combinations.

Characteristics
The manual drilling machine comprises a manual transmission mechanism, an axial feed mechanism, a guiding mechanism, a gap adjusting mechanism, a manual transmission mechanism, a spindle, a wrench connected to the upper end of the spindle, and the carbide drill bits and the sleeves connected to the lower end of the spindle. The axial feeding mechanism is composed of a hand wheel, a worm, a worm wheel, a nut and a screw rod; the guiding mechanism is formed by the upper end through a box cover and a nut, and the lower end is connected with the screw rod to form a gap adjusting mechanism. The adjusting nut connected to the main shaft is composed of two flat bearings provided on both sides of the upper end of the nut 6. The product has good sealing performance, stable work, low labor intensity and can be used in one machine. It can be used as a device for transporting liquid or gas pipes without stopping their conveying work for pressure drilling to install branch pipes.

Do you need a drill? -part 1

First of all, what is a drilling machine?
A drill is a general term for machinery and equipment that leaves a cylindrical hole or hole in a target by means of a rotary or rotary extrusion using a harder and sharper tool than the target. The desired effect is achieved by drilling precision parts. The drilling machine has a semi-automatic drilling machine and a fully automatic drilling machine. With the increase in human resource costs, most enterprises consider the automatic drilling machine as the development direction. With the development of the times, the drilling technology of the automatic drilling machine has been improved, and the automatic drilling machine is used to drill various metal molds, straps and jewelry, and the advantages are obvious.

What is drilling?
Drilling refers to the operation of machining a hole in a solid material with a drill bit, which means that choosing the right carbide drill bits is quite important. Here is the drilling work in the exploration work, as well as the auxiliary tools needed for drilling and some emergency measures. In the geological exploration work, the cylindrical hole with a small diameter and a large depth drilled into the underground by drilling equipment is also called drilling. Drilling holes for oil and gas and groundwater are larger in diameter. The diameter and depth of the borehole depend on the depth of the burial of the geology and minerals and the use of the borehole.

Classification application
The drilling rig is the main machine for completing the drilling construction. It drives the drilling tool and the drill bit to drill deep into the formation, and through the elevator on the drilling rig to complete the auxiliary work such as lifting the drill and casing, extracting the core, and replacing the drill bit. The main function of the pump is to deliver flushing fluid to the bore to clean the bottom of the hole, cool the drill bit and lubricate the drill.

How to Choose a Drill for Metal

A good drill for metal is able to drill a lot of holes in the hardest materials prior to the expiration of its service life, thus it should not blunt and, especially, go wrong. Such can be achieved by performance of the drill only if it is properly matched by the drilled material is ground is necessarily produced and qualitatively.

Make sure that the drill is made of a special high-speed steel drill of only this material can retain its properties at extremely high temperatures encountered in drilling location. High speed steel necessarily contains molybdenum and tungsten, which provides it superior durability.

When you select a drill for metal, note its color. The cheapest are gray drill, they are made ​​of ordinary steel such drills is very short-lived, and some varieties of steel they simply cannot cope. Black drills get their color due to additional treatment with superheated steam, they much stronger than usual. The best drills are carbide drill bits, coated with a rich golden color. This color drill means that it is covered with titanium nitride, which gives it the highest durability. Drilling such a tool will be much easier and faster, but its price is higher.

When choosing a drill you need to know what size hole you want to drill. For sure the drill diameter is given, and therefore the diameter of the resulting hole with it. Make sure that the mark begins with the letter P - it will mean that the drill bit made ​​of high speed steel. Since the drill for metal are usually made ​​of titanium, cobalt or tungsten alloys, it is necessarily reflected in the marking. BTW, you can buy the electronic tools or accessories (e.g. nibbler drill attachment) at Banggood for high quality and reasonable prices.


The quality and cutting speed is affected not only the material from which the drill bit is made, but the quality sharpening it. Only a well sharpened drill bit is able to cope with the metal, low-quality drill very fast, very cheap - after the first drilling.
