CNC MACHINING CENTER CUTTING PARAMETERS TABLE

CNC machining can be divided into two categories: ordinary machining and high-speed machining.
Ordinary machine generally refers to the machine tool with a revolution of less than 8000; high-speed machine generally refers to the machine tool with a revolution of more than 12000, and the machine tool between 8000 and 12000 is called quasi high-speed machine.
CNC machining process is usually divided into three categories: rough cutting, medium light (semi fine) and smooth cutter (fine milling). Generally speaking, it is better to use large cutter (flying cutter and end milling cutter) and large cutting depth and step (heavy cutting) for rough cutting, so as to remove materials quickly and in large quantities. In order to obtain the perfect surface accuracy, light cutting (small cutting depth, small step) with high speed and feed is used. End milling cutter (or fillet cutter) and flying cutter for smooth surface, end milling cutter for smooth vertical wall and ball cutter (or fillet cutter) for smooth surface.

In the process of machining, appropriate cutting tools should be selected according to the material hardness of the parts to be processed, such as plastic, wood, etc. domestic white steel knives can be selected.
Copper, aluminum and steel with hardness less than 38 degrees Rockwell (such as 45 steel and trump material) shall be imported steel knives and domestic high-quality steel knives. For materials with high hardness (such as hardened die steel), alloy knife, titanium plated knife or tungsten steel knife should be preferred.
In this paper, some cutting parameters of popular CNC machining center are provided for reference. Various kinds of cutting tools (flying knife, white steel, end milling cutter, tungsten steel flat milling cutter, white steel ball cutter, tungsten steel ball cutter) are described respectively for roughening and smooth cutter. Due to the large number of workpiece materials, this table only describes the representative aluminum alloy, 45 steel and stainless steel.

CNC MACHINE BE CLASSIFIED BY SERVO CONTROL MODE

Servo control mode to classify CNC machine tool. (1) open loop control CNC machine tool The feed servo drive of this kind of machine tool is open-loop, that is, there is no detection feedback device. Generally, its driving motor is a stepping motor. The main feature of stepping motor is that every time the control circuit changes the command pulse signal, the motor will rotate a step angle, and the motor itself has self-locking ability. The drive circuit is controlled by the pulse distributor, which controls the coordinate displacement by changing the number of pulses, the displacement speed by changing the frequency of pulses, and the direction of displacement by changing the distribution sequence of pulses. Therefore, this control mode is characterized by convenient control, simple structure and low price. The command signal flow from the CNC system is unidirectional, so there is no stability problem of the control system, but because the error of the mechanical transmission...

Tapping failure reasons analysis

After the first metal part be tapped, we always to check it: if pass the thread gauge inspection? The inspection result is OK, we can do mass production. If it fails, We should consider which reasons cause tapping faiulre. KYLT provide Metal Machining services for:  WEDM, EDM, DRILL, TAPPING ,  CNC LATHING ,  CNC MILLING ,  ALUMINUM / MAGNESIUM / PLASTIC RAPID PROTOTYPES MAKING . 1PCS ORDER IS ALLOWED. Aluminum CNC machined workpiece Normally, the following reasons may cause screw thread faiulre: 1) UNQUALIFIED TAP Tap is wear or bad 2) QUALIFIED DRILLING HOLE (BEFORE TAPPING) If the hole is too small, because of friction, will increase the difficulty of tapping, while tapping faster wear, and vice versa, the hole is too big, it can easily tap into, but the quality of teeth is very poor, because the diameter of teeth will become larger, relative to the screw nut bonding force is insufficient, easy to slide teeth. In M3 *0.5, the correct hole (general...

SELECTION PRINCIPLE OF CUTTING PARAMETERS FOR SCREW THREAD TURNING

Because the pitch (or lead) of the thread is specified by the drawing, the key to choose the cutting parameters when  turning  the screw thread is to determine the spindle speed n and the cutting depth AP. 1) SELECTION OF SPINDLE SPEED TO DO SCREW THREAD TURNING According to the mechanism that the spindle turns 1 and the cutter feeds 1 lead when turning the thread, the feed speed of the CNC lathe is determined by the selected spindle speed. The thread lead (which is the pitch when the thread is single head thread) instructed in the thread processing program section is equivalent to the feed speed VF VF = n f (1) expressed by the feed rate f (mm / R) From Formula 1, it can be seen that the feed speed VF is proportional to the feed amount F. if the spindle speed of the machine tool is selected too high, the converted feed speed will greatly exceed the rated feed speed of the machine tool. Therefore, when selecting the rotation speed of the main shaft for turning the threa...
