+ | Been talking about a 5 axis CNC machine for quite some time now. | ||
+ | Since no one is going to be donating one anytime soon... we are going to build one. | ||
+ | |||
+ | We were considering using iron castings. | ||
+ | http:< | ||
+ | |||
+ | Once surface ground they will have a nice locations for linear rails as the flanges are just over an inch thick. | ||
+ | |||
+ | We already have 5 sets of brand new THK rails... each has 6 sets of SHS15R3 and two 600mm rails. | ||
+ | {{: | ||
+ | |||
+ | Unfortunately the H beams alone won't dampen the vibrations of the machine enough. | ||
+ | So we will fill the H beams with epoxy granite, a blend of epoxy, sand, filler and other aggregate. | ||
+ | http:< | ||
+ | E/G has about 10 times the damping of cast iron and is widely used in making precision machine bases. | ||
+ | |||
+ | For the A and B axis, we will probably use something like: | ||
+ | {{: | ||
+ | http:< | ||
+ | For the price its very accurate. | ||
+ | http:< | ||
+ | At roughly 4k a pop. | ||
+ | Motor for rotary: PK569PMA-R28 | ||
+ | |||
+ | So with all that attached to the head and the spindle we will need some way to counterbalance the weight. | ||
+ | So we will use something like: | ||
+ | http:< | ||
+ | |||
+ | Pneumatic tension springs. | ||
+ | |||
+ | We still need to pick a spindle, one with auto tool change ability. | ||
+ | And all sorts of other little bits.... should be fun. | ||
