I have ordered the ARC one shot lubrication pump. I can keep most of the lubrication pipework internal to the mill avoiding lots of external pipes, should be a neat solution.

I'm thinking ISO 220 will be a good all round choice for the ball screws + vertical and horizontal slides using a one shot lubrication system. Nick, thanks for the additional information. Home Kontaktieren Sie uns Blog PowerMate Sicherheitstransport-Produkte Motorisierte Treppensteiger-Sackkarren und LiftGates. Just to confirm my choice of oil viscosity, Hiwin (as fitted to my machine) recomend Mobilgear 630 for standard use. PowerMate emphasizes regular maintenance of the ball screw assembly to increase efficiency and prolong the life of the machine. Involute Curve - yes, I will be ordering the ARC lubricating system. I may follow Nick's suggestion and use ISO 220 for everything. That's clear cut then, I wiil include the ball screws within my one shot lubricating system so they will be lubricated along with tte slideways using ISO 68 oil. This lubes all the linear rails AND the ball screws. I use the ISO 220 Slideway in the automatic oiler fitted to my Syil X5 Plus. Idealy use an ISO 68 Slideway oil for any Horizontal surfaces and screws, then use an ISO 220 Slideway oil for the Vertical surfaces and screws. Have a look here, a design guide for lubrication of ball screws **LINK** I think Arc Euro do a one shot oiling kit. Look at NSK, SKF, Hiwin, THK and many other original screw manufacturers for guidance if in doubt. In hobby use an occasional lube into the ball nut will suffice, just ensure the wipers in the ball nut keep the swarf out.

Over the years we never had a ballscrew fail or linear way either. Now in answer to your question, we used a timed one shot oil system using a slide way oil as this lubricated all the machine including metal to metal slide ways in the early days before using linear ways. Ballscrews ranged from 20 to 80mm in diameter. These screws where mainly on machines with dedicated cycles, so going over the same length of ballscrew every cycle. I designed machine tools for most of my working life and used ball screws since the early eighties. It feeds oil to slideways and ballscrews on all three axes. My CNC mill has a piped oil system operated by a spring loaded handle. I am including a one shot lubricating system and I'm at the stage as to whether or not to include the ball screws, or alternatively, lubricate them separately using grease.Īll slideways on all my machines are oil, never grease mostly ISO68 slideway oil, although the grinders generally use thinner oil. It appears moly or PTFE additives should be avoided as these friction reducing agents can cause the balls to slip or skid. I'm converting a mill to CNC and using 16 dia X 5 pitch C7 rolled ball screws.Īny recommendations for ball screw lubrication?Ī Google search does not give a conclusive answer, in general for hobby use it appears to come down to either use slideway oil iso 68 or general purpose lithium grease.
