It is so much easier to keep the ways properly lubricated when it only takes a single pump of the lever. Also, the resale value of mills with one-shot oilers is greater than those without.
This oiler will improve the longevity of this mill. The third and final reasons was that that this mill had a one-shot oiler installed. My house is on a zero lot, so my neighbors are feet away. This direct, belt drive will not only spin the spindle at almost twice the speed of the geared motors found on other benchtop mills, which is great for me because I plan to cut a lot of aluminum, but it also is quieter. The second reason is that this is one of the few mills at this price point and formfactor that comes with a spindle that is directly driven by the motor. The 833TV seemed like a mill I could grow into. When it comes to machining time and part quality, heavier mills are more rigid and can take deeper cuts with less chattering. It weighs in at 750 lbs, which is heavy but still manageable for someone who only has access to an engine hoist. The first reason is that this is one of the larger benchtop mills with a X-axis travel of 22”, Y-axis travel of 11”, and Z-axis travel of 17”.
So why did I pick this mill and not a more common model like the Grizzly G0704 or PM-25MV? There were three reasons for my choice: D-Flo's with his freshly uncrated PM-833TV Ultimately, I am happy with my purchase as this will be a great little machine to hone my machining skills on. My first plan was to buy a commercially available CNC mill from Haas or Tormach to avoid the hassle of converting a manual mill, but these CNC mills are just too expensive for someone like me that doesn’t plan to use his mill to turn a profit, especially when you start to add on fancy features like rigid tapping and work probing. Before I get into why this mill stood out to me, I have to be honest with you. It is an imported Taiwanese benchtop mill that is of slightly higher quality than the average mill of this form factor. To expand the capabilities of this benchtop mill, I have decided to convert it to CNC. I am getting closer to fulfilling this goal with the acquisition of a Precision Matthews 833TV mill. However, it has been a longstanding goal of mine to expand the metalworking capabilities of my shop because the ability to make custom metal parts would allow me to build some projects that otherwise would have been impossible. I can 3D print the plastic and carve up the wood with my CNC router. My go to materials have been plastic and wood.
