How much backlash compensation is acceptable ? As mentioned above, all machines have some backlash adjustment, even when brand new and at ship time. As the machine wears, that value needs to be increased. Normal wear might have .005" - .010" adjustment in a ballscrew. If the value needs to be more than .010", it might be time to take a deeper look.
As discussed before UP-grinding is strongly based on the availability of appropriate enabling technologies, i.e. ultra-precision machine tools, grinding tools, tool conditioning and grinding fluids. These will be characterized in the following. 4.1. Machine tools for ultra-precision grinding

(1) For intermittent grinding required for ride correction under 740, ensure that the grinding machine will grind a strip at least 3 feet wide and has an effective wheel base of 12 feet or more. The engineer may require continuous grinding equipment if intermittent grinding equipment does not produce acceptable results. 420.3.3 Final Surface Finish

Special gear cutting or grinding machines are required for pro-cessing each helix angle. Normal module （SH） Modifications of spur gears are made by gear cutting or grinding machines, even if they have dif-ferent helix angles. Have a center distance value differ-ent from that of a spur gear, although they have the same module size and
Backlash – Backlash (lash) is the relative axial clearance between a screw and nut without rotation of the screw or nut. Backlash information for PowerAc™ Acme Screws and Nuts is listed within the data section of this catalog. Lash will always increase with use. Helix has developed several unique ways to

Slant bed VS Flat bed. Flat bed CNC lathes, two rails parallel to the plane and the ground plane. Slant bed CNC lathes, two rails and the plane of the ground plane intersect into a bevel angle has 30 °, 45 °, 60 °, 75 ° points. From the machine side, the level of bed CNC lathe bed was a square, slant bed CNC lathe bed right-angled triangle.
It is not unusual to see backlash of 0.005″ on a good quality manual machine with ACME screws, and that figure can easily deteriorate to 0.025″ or worse on a badly worn machine. There are other sources too, such as the gibs or the mounting of the nut or screw. There can be play in how a hand wheel or motor is attached to the shaft as well.
Large. CNC machine for crankshaft company. UK company Lincoln Crankshaft & Machine (LC&M) says it has purchased a new 11,000mm capacity CNC orbital shaft & crankshaft grinding machine.

I agree that things are changing in CNC world and I just do not think the market is there for a CNC retrofit kit for manual grinding machines for a few reasons. In my opinion one of the reasons why the market is not there is that the days of having a couple of manual grinders and a wall of 1000 masters are gone.
The CNC machine tools are spatial machines that are able to control computer. There are two types of machine tools structure, C-frame and gantry-frame. A CNC gantry ma-chine tool is defined as a computer numerically controlled machine that is programmed and controlled through a computer. Its CNC controller offers very short setup time ...

If during operation of an angle grinder you hear a noise that was not previously there, be sure to check the condition of the bearings.. The stator is a stationary component in an electric motor, there is a winding on it. The angle grinder rarely breaks down directly from the stator. The gearbox is responsible for the rotation of the gear.
