What is CNC routing?
CNC Routing is a manufacturing process by which a router is controlled by a computer to cut a sheet of material. CNC stands for computer numerical control. Computer conrolled movement of the machine is based on the Cartesian coordinate system (X, Y, Z) allowing for three dimensional shaping.
A CNC router is similar to a plotter which moves a pen across a surface along the X and Y axes to create a drawing. But a CNC router moves a cutting tool across a large table along the X and Y axes as well as up and down along the Z axis. This allows the router to create pocket cuts into the material.
The cutting tool looks like a drill bit, but unlike a drill bit a router is designed to cut from the sides as well as the tip. The router, also referred to as a spindle, is the motor that spins the cutter.
Do JCUT products come with a warranty?
Yes. All JCUT products are warranted for one year (unless otherwise noted) against defects in materials and workmanship. During that time, JCUT will replace any defective parts that are returned to our warehouse, free of charge. Upon receipt of the defective parts,JCUT technicians will arrange with you to send replacement parts immediately. This warranty does not cover parts that are worn out through the negligence on the part of the operator nor does it cover consequential damages resulting from defects in material or workmanship.
How much does it cost to use?
There is no cost to use the machine. However, you are responsible for supplying your own materials. Occasionally we require users to purchase their own router bits, depending on how much routing is to be done and the type of material.
How long will my CNC order take to arrive?
CNC orders will generally be made within one to two weeks.
Shipping time depends on your location, but will usually take between one day and one week.
How much will CNC routing my design cost?
The cost is determined by the complexity of your design and the material type and thickness you've chosen.
The CNC cuts materials at a range of speeds and as a rule it takes longer to cut thicker materials. As a general rule of thumb, the more lines your design has, the more it will cost to make.
How many years have you been in business?
We are manufacturer,specialize in this fields for many years. JCUT has engineered and manufactured quality machines since 2000.
What type of maintenance doed the machine require?
Other than keeping it clean of sawdust and not letting it build up on the rails, etc. The machine requires no scheduled maintenance. All the bearings are sealed and lubricated. The few bushings it uses are oil-lite bronze and require no lubrication. We designed it with as few moving parts as possible and every component was selected with long service life and low maintenance operation in mind. The timing belts are very high quality steel lined poly. We have one older CNC machine in our shop with just neoprene glass lined belts that are 30 years old, still working fine and was the inspiration for this machine design. All the timing pulleys are high quality machined aluminum, again, requiring no maintenance.
Can I put a different table on my machine?
Yes! We opted for MDF as a good basic table that is flat and very inexpensive to replace. It just bolts to the upper surface of the machine base. As is the case with many routing operations, the cutter may extend through the workpiece into the table's surface. It is because of this that most users prefer to attach an inexpensive table surface as a spoil board to be thrown away when used up.
I'm new to CNC, can you assist me a bit if i need it?
Sure, we are always just an email or phone call away. Our e-mail is monitored closely and you will receive an answer to your question in prompt order. We offer training, we will assist you in making your CNC machining experience a success. There is a wealth of information on the web. There are instructional videos available for download as well as an reference manual.
What is G-code?
G-code is essentially a standard machine language whereby NIST standard G commands are given and interpreted by the CNC controller. Below is a basic run down of how a part is drawn and the subsequent code is produced.
What should I know about routers?
Compact CNC systems are often mounted with a low-cost shop router instead of a more expensive variable speed spindle. In spite of being quite noisy, a router can give years of reliable service in operations requiring modest cutting power and minimal speed control. There are two types of routers commonly in use on CNC machines: plunge routers and laminate trimmers. Plunge routers are designed for continuous use and are equipped with adequate cooling to prevent excessive heat build up. The shafts are typically mounted in high-quality, sealed ball (or roller) bearings and backed up with a thrust bearing to allow drilling and ramp milling. They are intended for intermittent duty, but, with light loading, can provide reasonable service in a CNC environment.
Spindle speed (RPM) is very important when you are cutting with microtools. If you are fitting a shop router to your CNC, we recommend that you use a variable speed plunge-style router. Plunge routers typically operate in the 20,000 to 24,000 RPM range, as opposed to 10,000 to 22,000 RPM for the single speed laminate trimmers. More importantly, they are usually built around a so-called universal AC/DC motors that, with external controllers, can be operated from a few hundred RPM up to 120% of the rated maximum. One disadvantage of plunge routers is that most of them vent all of the cooling air through the bottom. Unless you redirect this blast of air, it will render any vacuum removal of debris totally useless and your shop will slowly be buried in sawdust.
