Technical features of machines for sharpening saws, what to look out for
Honing a few years in our service center on saws grinding machine with specialized resin bonded disc WoodMizer company (WM), we know all the advantages and disadvantages of this machine. Attempts to repeat this machine well other manufacturers were in our opinion worse than the original in terms of convenience, and most importantly, from the standpoint of the result and ensure resource turning the grinding wheel.
Life of the drive , in addition to its own characteristics , mainly depends on the quality of manufacturing sites sharpener . The worst thing for cbn grinding wheel - it backlash machine. If they are, they are all conventional grinding and thus remain on the grinding that simply using a different cam trying to remake a job with boron nitride disks. Then the disc while turning may not exactly fall into the tooth profile and unpredictable beats it on the front , then on the back side , breaking sawtooth profiles . Then have sharp tips of the teeth begin to cut the drive significantly reducing his term . Thus, even starting to grind normally such machines instead of a year of work , or 10 -15km drive bore killed after 500 -700m or 1-3 weeks , which is not economically efficient.
Manufacturers of special purpose machines for sharpening saws profile disk , except WM, mostly bad resource nodes expect their machines . The same result is obtained from the manufacturers who only superficially copy on their machines , some nodes PZSL30/60 not observing precision manufacturing technology and all the subtleties in the assembly allows our machine for a long time to work with virtually no backlash . In addition, many manufacturers to reduce the cost , is used to push the saw blades from car engines , which are generally not designed for permanent and long-term operation , and so after a few months of work necessarily begin play. The disc is not installed directly on the motor shaft , and slozhnonastraivaemuyu and, accordingly , relatively quickly blab , three-step transfer of rotation through additional straps . Such machines have them immediately or relatively quickly as small clearances , which also killed in the same disc, but relatively slowly. Disk resource is usually enough for 1 -3km or 1- 3months . That is , buying such a machine and save first - 15000rub 5000 , a man in a few months it loses all savings , and then drives on the money each year will have to buy another machine.
!!! Managers who unknowingly or specially persuade buyers to purchase such machines, making the firm "disservice" - not increasing and decreasing as a result of the number of actual buyers.
!!! The buyer subsequently realized how he had been deceived, not only the already highly negative attitude towards the company seller, but, more importantly, it forms the opinion in its environment and thus many potential buyers, not just grinding, but also any other equipment just immediately go to other firms that sell the same product assortment.
In our machine, we removed the deficiencies identified in the construction of all known manufacturers, and added what they lacked to provide a convenient and high-quality sharpening:
