FAQ

Stepper motor control is the most cost-effective way to control a machine tool. The accuracy is exceptional, and the price is very reasonable. The only limitation is that the maximum speeds for rapid and cutting moves are not as high as for servo control.

Servo control uses feedback from an encoder to constantly monitor the machine tool’s exact position. Using the feedback signals, the control system can achieve very high speeds and exceptional accuracy, even under very strenuous conditions. A servo motor essentially has the ability to correct itself it is ever out of position.

The difference between stepper and servo control can be explained using the analogy of walking through your home in the dark. You know how to get from place to place, but you go move slowly because you don’t want to lose your position and bump into a wall. This is like a stepper motor. If you instead turned the light on, you walk much faster because you are getting constant feedback from your eyes with respect to where you are. This is like a servo motor.

If you work on flat material, what is the maximum size(length, width and thickness) of your processing material?

If you work on column material, what is the maximum diameter and length of the processing material?

Then we can recommend you suitable size of machine.

The speeds vary depending on which model. Each model’s speeds and accuracy are published on our website. However, your cutting speed (feed rate) will depend upon various factors, including:

Machine set-up —Variables that affect every machining application are spindle horsepower, rigidity and runout, collet condition, hold down system and tool sharpness.

Number of flutes — Single-flute tools should generally be fed at a slightly higher rate (approximately 10%) than double-flute tools.

Bit diameter — A 3/8″ bit can be fed 10% faster than a 1/4″ bit. A 1/2″ bit can be fed 20% faster than a 1/4″ bit.

Depth of cut — Your feed rate should be decreased approximately 25% for each multiple of the depth of cut. (If depth is two times, reduce by 25%; if depth is three times, reduce by 50%.)

Spindle speed — The faster the RPM of your spindle, the quicker you can cut your parts.

The type and thickness of your material, the type of tooling you’re using and the nature of your parts will determine what type of spindle you need. Sail CNC is more than happy to assist you in determining the ideal spindle for your needs.
