The lack of affordable (real) CNC VMC frames with serious rigidity has been the most elusive animal for the serious machine builder and that is about to change.
What you see in the attached picture is a general overview of the product currently in the midst of casting in ductile iron.
Frame foot-print is 1168.4mm x 840mm x 950mm, table is 540mm x 350mm with a table height of 444.5mm (17.5in) and basically has 100% table travel due to design.
The column is 125mm (5in) x 200mm (8in) and all casting have a minimum wall thickness of 0.750in so you know strength/rigidity is present.
Designed for use with 25mm linear rails and 25mm (1in) metric/imperial ballscrews and 90mm or 110mm Servo motor making it an attractive solution for even the budget concious.
X, Y and Z 1in (25mm) x 0.200in (5.08mm) (pitch) imperial C5 ground ballscrews with double length (4in) anti-backlash nuts are $650.00 for the set, a price that can't be found anywhere else.
No more dovetail machine like the RF45, SEIG X2/X3/X4 and crappy conversion from leadscrews to ballscrews and head rebuiling, now you can get a frame designed specifically for CNC application and build it as you want/need.
We even tried 600W 60mm (5.73Nm peak holding torque) on the prototype and found them to work quite well on X-axis and Y-axis but worked to hard for Z-axis so we decided to limit the options to 90mm (7Nm or 12Nm peak) and 110mm (12Nm or 18Nm peak) servo motors.
The frame size is suitable for BT20 to BT30 spindles leaving you lots of wiggle room to configure it to your personal likings.
The frame can be supplied bare or with any option you want.
Initial prices are estimated to be $3,200.00 and up depending on options like linear guides, imperial/metric ballscrews, spindle, tool changer, CNC panel/controller, servo motors plus shipping.
Since it is in the early production stages it's hard to say how long it will take to roll the first 25pcs out the door as several trial pours will have to occur to ensure all parts are cast/made properly and I would like to add, anything you buy from me as a home/hobby user will be at cost pricing and not Servo Products retail pricing so it is something to consider instead of buying the SEIG X3 at $2,900.00 and have to spend all that money making these types of dove-tail machines CNC when it's easier to do it if you start with a machine already designed for CNC application.
The cost of my BT30 ATC spindle is $1615.00 plus shipping, it includes the pneumatic/hydraulic drawbar actuator and Servo Products (check them out) sells this for $2,499.00
My BT30 spindle was basically a purchased china made spindle and then I fixed everything that was wrong with it and had it produce for me at my expense so I am in every sense of the word the manufacturer of this product and if Servo Products buys it from me it has to be something they would consider good quality because they have to back it.
Reprimanding me for selling anything at cost or selling to anyone I want would not be in the best interest of Servo Products if they wish to sell these product, the ownership, design and prototypes are mine personally, their rights are in purchasing at cost only and does not preclude me from selling anything to other companies who want to build and sell their own (for a small profit of course) mid-size VMC.
Also in the works is a real variable frequency spindle motor (4 poles) 10,000RPM with encoder in a smaller package (140mm x 140mm or 180mm x 180mm and not 220mm x 220mm), it will be available in 2HP (3HP peak - 140mm x 140mm), 3HP (4HP peak - 140mm x 140mm), 4HP (5HP peak - 180mm x 180mm), 5HP (7HP peak - 180mm x 180mm) and the first prototype should be delivered to me in about 2-3 weeks, estimated price starts at $450.00 plus shipping.
For those on a tighter budget I have a (4 poles) 6,000RPM (8,000RPM for 30mins) 2HP (3HP peak - 180mm) variable frequency spindle motor without an encoder which can be purchased for $200.00 plus shipping (about $350.00 delivered).
All spindle motors include a 220V single-phase cooling fan (yes they're independent cooling) so RPM does not affect cooling.
All these spindle motors require a VFD and my initial testing has shown that 3HP is more than sufficient for the most demanding requirements of production work since the DooSam 4018 (BT30) comes with a 2.2KW spindle motor and this is a full size machine.
A 2.2KW (3HP) VFD's will run on 220V single phase and is my VFD of preference.
A new Delta VFD-B 2.2KW (3HP) with PG card can be purchased from me for about $375.00 plus shipping and a new Delta VFD-M 2.2KW (3HP) with PG card for about $425.00 plus shipping, a new Yaskawa AG615 3.7KW (5HP) with PG card can be purchased for $950.00 ($710.00 without PG card) plus shipping.
Serious inquiries should be directed to me rather than trashing this thread with nonsense.
