How To Buy A CNC Automatic Bridge Saws

The cnc automatic bridge saws is well known for its complete functions and user-friendly design. Equipped with the latest technology, It cuts slabs into tiles and processing counter-tops efficiently and precisely. The blade, together with vertical beam, are able to tilt 45 degree for angle cutting. The table turns 0 – 360° horizontally and can stop at any position for various angle cutting. It tilts 0 – 85° vertically for easy loading and unloading. The laser guide and sensor give high accuracy for every cutting. Color touch panel and wireless remote control perfect operation. Hydraulic System for easy load and unload of the material. The mono block mechanical body is made of very strong cast iron for stability and long lifetime. The automatic Bridge Saw with premium quality, full functions and favorable price has won trust and reputation from our customers,

CNC Automatic Bridge SawsThe bridge of this cnc automatic bridge saws has been built in large thickness normalized cast iron. Cast iron can give the bridge high level rigidity and prevent it from shape deformation. Two V-shaped tracks have been machined on the bridge top with small clearance to guide blade holder movement. The blade holder moving tracks are oil-bathed and covered by organ shield after installation.

How to buy a bridge saw

Your Location
Some important factors to consider are if you have room enough for the saw you want to purchase. In most cases, you need to leave some room around the saw for easy access, maintenance, and hook up considerations. Be sure you know exactly how large your potential saw is, where access is especially needed, and if there are any doors (electrical box?) that need room to open. Also, can a forklift loaded with stone easily access the saw’s designated area for simple loading of slabs?

Your Power
In most cases, full-sized bridge saws require 3 phase power at 220 – 240 volts. What kind of power do you have? If you don’t have 3 phase, will you get a generator (not optimal) or a rotary phase convertor $3,000 – $4,000)? If you want to convert to 3 phase power,

Your Needs
How many slabs do you cut per day? Per week? Do you need to cut arcs (5 axis saw) or do you do a lot of mitering? I often tell fabricators that to go to a full 5-axis CNC saw (prices typically start well north of $100K and go up a lot from there) without having a basic saw as back up might not be a good idea. Do you have the work volume to substantiate the purchase of an expensive ($100K+) saw? If you are a low-volume shop, can you get by with a basic saw that doesn’t miter? Do you realize the time savings that result from having a saw that can cut both the X axis and Y axis? It saves substantial time (minimal table rotation) when you have a saw head that rotates. Is a table that rotates and lifts automatically helpful or not critical? Is the saw you are thinking of low maintenance? Are the X and Y rails covered or exposed? Is there automatic lubrication? Do you want a mono-block style saw which is a once piece unit that keeps it’s accuracy over time and is easy to move or are you OK with a saw that has separate steel walls, or concrete walls you have to build? All of these are important questions that need to be addressed.

Your Employees
How equipped are your employees to run this new saw? Are they already familiar with the operation of a bridge saw or would this be new to them? Do some of them have good technical abilities both with fabrication and math? Do any of them understand machinery, maintenance, and basic repair? Do they want a saw that is simpler to run or do they want the complexity and capability of a CNC saw? If so, do any of them have experience drawing and understand CAD/CAM programming? Do you use physical templates or laser (digital) templates? Some people are under the misunderstanding that a basic bridge saw cannot be programmed while a CNC saw can. That’s not entirely true. Yes, there are super basic bridge saws that can only cut the X axis and have to have the table rotated for Y axis cuts and they don’t miter. Most of these type saws cannot be programmed in any way. However, there are mid-range saws that, while they are not CNC saws, do have programmable features allowing you simply program in multiple cuts along one axis, say an initial cut to straighten out the slab edge, followed by a 4″ backsplash cut, then a 24″ countertop cut, another 24″ cut, and a final 4″ backsplash. It’s a great feature and allows you to cut with confidence knowing that the saw will cut those sizes precisely because you’ve programmed it that way. Finally, a CNC saw requires a digital file (DXF) in order to cut. This means you have to 1) send it a digital file from a templator or 2) the draw the file on the computer’s screen OR 3) have someone draw it on a computer then import it into the saw. Then, once the program is loaded – the operator has to define for the saw how to cut along that template, where to start, where to finish, etc.

Used or New?
While it is often a possibility to find a used saw for sale, the great challenge is that in the stone industry (unlike the metal or wood working industries), saws have a tough life from the start. The combination of stone dust and water is VERY hard on a metal saw and there is a lot of wear and corrosion that comes with it. Buying a used saw is something that is challenging – you MUST go see the saw and hopefully you can see it in operation and not disassembled. You must also get a sense for how much life is left in it and how meticulous the owners were about maintaining it, fixing it, lubricating it. I often caution buyers about purchasing a saw that is more than 5-7 years old. It’s just a challenge and shouldn’t be taken lightly. You can often find used saws in the $15K – $30K range. New saws, the most basic, usually start in the mid to upper $30K area and go up from there. Mid-range saws are $45K – $75K and CNC saws start over $90K.

Who to Buy From
To me, when I purchase something, I don’t want to be pushed or pressured. I also want to feel as though the company I am dealing with isn’t just trying to sell something to me but instead has listened to me, heard my business story, understood my budget, and really wants to help me find the best saw that fits my needs and budget. Do they have a saw in your area that you can go see? Will they provide you with references to talk to about their experience with a particular saw or company? Do they invite you to visit their

What Can A Bridge Saw Be Used For?
CNC automatic bridge saws manufacturers design their power tools to cut stones, including granite. A slab of stone is placed on the table, and then the machine cuts it. Some machines are made specifically for cutting marble. They are equipped with programmable heads that can turn in multiple positions. This means they can follow all profiles and make recess and corner cuts for any marble work, including bathroom tops, kitchen tops, and curved chimney lintel.

CNC Automatic Bridge SawsBridge saws are versatile to allow cutting in every direction and angle. They can handle any cutting project, including cutting sink bowls. New generation saws can cut round, oval, or square sink bowls. These saws come with a gas attachment to enable you to connect extra tools to the diamond disk.
