| Using economic numerical control lathes skills | The current economic numerical control lathes are widely applied. It is inexpensive, nc system is reliable, in use to overcome the shortage, exert the advantages, can obtain good economic benefits. Now will use in some skills to you, for your reference. Key words: pneumatic press
A tool
Economic numerical control lathes are usually the system software tools compensation function. In order to facilitate, determine the relative position of the cutter knives, make the compensation procedures, still all requirements of rotary cutter point in the same position, basically is slightly higher than the spindle center. In order to clip the same part of the good tool for processing, can press below steps.
To control system input such a program - a length of longitudinal cutter, turning back after a longitudinal cutter turned again to retreat into the length, go back to the original location.
In the third claw chuck on top with dynamic gripping a manually or methods, rotary cutter is a tool clamping first, according to the requirement of the position, packed with top tool tip slightly higher lenticeled overlap, 0.2 ~ 0.5 mm. Reboot your system, make according to the input program operation, sw again after installation, a knife, can put all cutting tools.
Second, parts of the axial orientation
In batch processing parts, procedures and the origin of the time required to change, but don't clamping parts are in the same position. Use the following method can accurately to do this.
In a cone into the hole taper cone plug center, a adjustable screw.
Every time when the workpiece and clamping screw tightly. This would ensure the same kind of parts in the same position.
Adjust the length of the screw, can adapt to different parts of the required position.
Third, programming, avoid out-of-step
We know, stepping motor starting torque is lesser, speed increase gradually after rated torque. If we programming, make stepping motor just start into (or soon, so strong cutting) may appear less torque motor torque and cutting conditions of out-of-step, processing components unqualified or scrap. Repeated use of such a program, because "out-of-step", the origin place will also change, which makes the batch processing unqualified or scrap parts. So, in the programming should consider when stepping motor startup characteristics, in the stepping motor reached the rated speed cutting tools to enter again. According to our experience, let the cutter no-load running after cutting, 6mm again into hasn't happened "out-of-step" phenomenon.
Four, programming, avoid tool wear error
We know that a new grinding tools, good started processing parts, tool wear irregular and faster, in small batches, smooth into parts with new tools, so when processing components, processing components should inspect. For small and medium-sized axial parts about 4 ~ 5 pieces after cutting into smooth state. At this moment, tool wear and machining parts is proportional to the number of basically. Just coincidence programming, add tools can guarantee compensation quantity and quality of parts batch processing.
