There's a lot of questions as to whether a Tormach PNC 1100 R8 spindle can be upgraded to a Tormach BT30 spindle. However, there's no confirmation of someone having done it. The comment by Tormach "Davie" on this TORMACH Forum post "If you have a PCNC1100 then conversion to BT30 is more of a choose your own adventure", seems to indicate that it is possible but not supported. It seems that the head casting and spindle bore are identical with the PCNC 1100, 1100m and 1100mx. Th

Tormach used to offer a rebuild kit for their spindle. The instructions are still here: https://knowledgebase.tormach.com/pcnc-1100/pcnc-1100-spindle-rebuild Now they only sell the whole spindle. If you want to rebuild it by replacing the bearings, you have to order them yourself. TOP BEARINGS 7007C/P5 DT BOTTOM BEARINGS 7008C/P5 DT NSK 2008CTRDULP4Y

This video has a detailed full teardown and replacement of the Tormach BT30 Spindle Bearings. UPPER BEARINGS The upper bearings are sitting on top of each other. There is no spacer. These are the markings on what someone claims is the stock upper bearings (unverified) HP7006C-2RZTN12/P5 In a comment from the above video: Part number breakdown: 70 Dimension Series Indicates an angular contact ball bearing in the 70 series (ISO 10 dimension series).

There are many different designs for oil skimmers to remove way oil from coolant. Belt Tube Disc Most rely on the oil clinging to plastic or metal surfaces, while the coolant does not. The clinging oil is pulled up to a scraper, scraped off the belt (or tube, disc), and then runs down into a disposal container. The issue with these designs is that they also pick up a lot of coolant with the oil, as much as 50%, so a second oil separation unit is required to drain the excess c

DISCLAIMER The following info are changes that were made to our equipment and for our reference only. Do not attempt to make any changes to your equipment. Only certified technicians with the proper skills are permitted to make changes to equipment. Open TM-1 machines had spindle speed limited to 4000 RPM and rapids limited to 200 ipm for safety reasons. An enclosed TM-1 has a 6000rpm spindle and 400 ipm rapids. We're going to enclose our TM-1 milling machine, so we can incre

WORK OFFSETS (X and Y) USING THE 3D TASTER PROBE - (HAAS Video Link to 0:27) The 3D taster (Tschorn) probe is calibrated to be centered on the spindle axis when the indicator value reads 0 in X or Y. Use the 3D taster (Tschorn) Probe, touch the part with the probe until the indicator is at 0. This is the edge of the part, no offset calculation is necessary Make sure the correct jog axis is selected that is to be zeroed, and press PART ZERO SET Repeat for the other axis. USING

MAINTENANCE Download the PDF Manual Variable Speed Belt Drive The variable speed belt replacement # is 1922V443 and can be purchased here on Amazon. The most difficult part of changing the belt is putting the new one on because the spring-loaded pulley attached to the motor needs to be kept open.

THE FRAME The proliferation of inexpensive laser cutter engravers has dropped the cost of simple CNC machines that can support the load of a torch head. Normally CNC plasma cutter frames are built strong, often as strong as a CNC router. For non-industrial use, the frame doesn't need to be nearly as strong, so these basic laser engravers will work. $150 - 350mm x 350mm - https://s.click.aliexpress.com/e/_mP2J8hM DIY CNC Engraver Kits Wood Carving Engraving Cutting Machine Des

The stock memory in a HAAS CNC machine pre-2007 or so is only 1MB (however there is 16MB onboard, but it is locked). You can pay $$$$ to unlock the 16MB. The only way to load files is to use the floppy drive, or over RS232 serial. The floppy drive has a limited capacity and the file still needs to be copied over to the machine to run, taking up precious memory space. I purchased the Micro DNC 2, because it allows you to upload files (no size limit) from a USB key to the HAAS
