Fully automatic drilling machine characteristic

Drilling machine is the use of more hard and sharp tool than the work piece, by means of rotary cutting or rotary extrusion way, in work piece leave cylindrical hole or cavity machinery and equipment general terms. Can also be called a drilling machine, perforating machine, trepanning machine, hole machine etc. By means of proceeds drill for precision part, achieve the anticipative effect. Drilling machine has semi-automatic drilling machine and fully automatic drilling machine, with the increase of human resource cost, most companies are starting to use fully automatic drilling machine. With the development of the era, automatic drilling machine drilling technology ascension, fully automatic drilling machine fairly widely used in all walks of life, because fully automatic drilling machine has the following characteristics.

1, fully automatic baiting;

2, use flat plate type mould, low cost, strong commonality, easy fabrication, machining efficiency is high;

3, processing size (2 – 40 mm), can completely meet the requirement of industry product processing size, special specification can be customized;

4, use fully automatic computer debug machine way, hole location to the number of edges is adjustable range (0-15 mm), to the base adjustable range (0-7 mm), at the same time have compensation value adjustment function, make the hole position adjustment is more accurate, more convenient;

5, computer real-time monitoring drilling mouth protection system, material card, empty material, parameter error alarm system;

6, one person can operate more drilling machines at the same time, improve efficiency, reduce cost, improve enterprise competitiveness;

7, manufacturer provides a standard tube, operation more convenient.

How to judge the tool chuck quality is good or bad?

Tool chuck in a variety of cutting tool and machining center spindle provide connection standard. High precision tool chuck difference also depends on the manufacturing tolerance, qualified frock clamp chuck and waste distinguish is often lie in critical size microscopic difference. Tool chuck can be used in drill head, machine tool, drilling machine. So how to judge tool chuck quality is good or bad? You can judge according to the following four.


Cutter axis rotary must be precision consistent with the machine tool spindle rotary axis. Although implementation seemingly perfect method of concentricity is very clear, but also very complex. Even if the spindle fitment chaos problem resolved soon, problem will steer business terminal of tool chuck.

Clamping strength

Clamping force is the ability to prevent the cutting tool rotation in the chuck. Use jacket is the main reason of cause clamping force change. Single Angle jacket can put greater clamping force, and can ensure good concentricity. To make composed of collet, jacket and tool components can get as much as possible good concentricity, must adopt special measuring tool or high precision cutting tool presetters to measure the concentricity. In order to get the best combination of clamping force and the concentricity, should adopt hydraulic chuck or hot shrinkage chuck, so that we can not use the jacket.


Each processed products have tolerance, is mainly used to measure the size of manufacturing variation, the change is smaller, the tolerance is tighter.


Tool chuck imbalance is usually derived from the functional design, such as end milling chuck locking screw or CAT chuck drive slot depth is unequal. But due to many reasons, the unbalance produce is often random. No matter what imbalance comes from where, all need to remove part of the material, in order to eliminate unbalance, correction effect. Another solution is to use an adjustable balance tool chuck, can be adjusted by the radial screw or balance ring to eliminate the imbalance. In this case, we need to determine the size and location of the tool chuck imbalance, and this will need to use the complex balance detector.

Motor is a kind of rotary electric machine, it is a device converts electrical energy into mechanical energy. It is using electric coil creates a rotating magnetic field and is used to turn the mouse cage closure of aluminum frame to form dynamic rotating magnetic torque. Its working principle is magnetic field in the current stress, make motor rotate.

Motor is mainly composed of stator and rotor, the motion direction of electrify wire in the magnetic field relate to the current direction and magnetic induction line direction. According to different use of power, motor can be divided into dc motor and ac motor, motor in the electric power system is mostly ac motor, synchronous motor or induction motor.

When motor running need to pay attention to make it load characteristic and motor characteristic phase match, avoid aerodyne or shut down. Motor can provide rate of work range is big, from milliwatt magnitude to million kilowatt. It is very convenient to use and control, has self starting, accelerating, braking, reverse, stopper live etc. ability, and can satisfy the various operation requirements; the work efficiency of the motor is higher, and no smoke, odor, polluting the environment, noise is small. Because of its series of advantages, it so widely used in all walks of life.

Machine tooldrilling machine, water pump, belt conveyor fan etc. need motor drive; Electric locomotive, elevator, need motor traction. Family life of the electric fan, refrigerator, washing machine, and even all kinds of motor toys is inseparable from the motor. Motor has been used in all aspects of life in modern society.

Moreover all kinds of motors are used in ac asynchronous motor (also known as induction motor). It is convenient to use, reliable operation, low cost, firm structure, but power factor is low, speed regulation is also more difficult. Large capacity low speed power machine is commonly used motor. Not only synchronous motor power factor is high, but its speed has nothing to do with the load size, only depends on the line frequency. Work is more stable. In require wide scope speed regulation occasion more use dc motor. But it has a commutator, the structure is complex, the price is expensive, maintenance is difficult, not suitable for bad environment.

Use drilling machine to pay attention to safety

 Abstract: In the daily work, drilling machine not only to bring many benefits to the people, and improve people’s working efficiency. However, during operation, we must always pay attention to safety, so as to avoid accidents.
  Drilling machine in the daily work brings many benefits to people, improves people’s working efficiency, but must pay attention to safety when operation, so as to avoid accidents.
  What are the precautions for drilling machine operation?
1, according to the drilling material selects the appropriate drill or a drill mouth.
2, according to the drilling material adjusting speed; speed too fast drill heating low-melting material will soften. Speed too slow soft material adhesion will happen.
3, according to the drill hole depth and diameter, determine the feed rate of the drilling machine.
4, drilling machines are high speed rotating feed; need to pay attention to safety.
5, note that the sharpness of drill, needs regular drill grinder or replaces the drill bit.
6, the drill shaft should be lubricated regularly.
