Precision grinding of screw rotors using method · A spatial contact curve equation for screw rotor grinding is proposed, which includes three parameters: center distance, swivel angle, initial phase angle A parameterized program was designed by the contact curve equation, and the grinding wheel axialsection profiles were calculated for
However, using a grinder makes rather an awful screw, it really needs to be polished to the max. Be prepared to polish it at high speeds – all day long, til a 3000 grid :-)
The CNC grinding wheel dresser of the screw rotor grinder uses a segmented grinding method to dress the grinding wheel, as shown in Figure 2. The profile of the grinding wheel is divided into two curves called CD and CH with point C on the V-axis as the boundary point, where the radius of the grinding wheel is the largest.
Rexroth – Precision Ball Screw Assemblies Product Overview Definition of a precision ball screw assembly DIN 69 051 Part 1 defines a ball screw as follows: An assembly comprising a ball screw shaft and a ball nut and which is capable of converting rotary motion into linear motion and vice versa. The rolling elements of the assembly are balls.
For non-continuous-dress creep-feed grinding, the calculation is straightforward. For continuous dressing, the calculation has more steps, but in either case, it is possible to manage the cost of grinding by predicting the life of the wheel.

The parameters of ball screw raceway profile directly determine the load distribution in ball screws, and therefore affect the contact rigidity, friction characteristics, and service life [].The grinding surface of the ball screw raceway is Archimedes spiral, which has a relatively complex process compared with cylindrical grinding and surface machining.
ME EN 7960 – Precision Machine Design – Ball Screw Calculations 4-3 Based on Load • A ball screw transforms rotational motion into translational motion. As a result, the shaft is subject to loads: – Thrust force (the sum of all external forces such as machining load, gravity, friction, inertial forces, etc.).
Angular velocities of the screw rotor and grinding wheel are ω h and ω t respectively when they are rotating. Then, the linear velocity vector v h of point M on the helical surface of the rotor is shown in Eq. (), and the linear velocity vector v t of point M on the revolving surface of the grinding wheel can be defined by Eq()Further, the relative linear velocity vector …
Upon studying the form grinding principle of helical groove and the conjugate movement between the grinding wheel and screw rotor, the equation of their contact line is firstly derived. The problem of smoothing the profile of grinding wheel is then solved by using the point selection smoothing method which is concludes from the theory of complex curves and numerical analysis.

2. Continuous dressing, which is beneficial in large-quantity production in materials that are difficult to machine or grind.The continuous dressing enables the grinding wheel to stay sharp constantly, while maintaining intricate forms. Continuous-dress creep-feed grinding uses an overhead diamond dressing roll to plunge dress continuously during the grinding cycle.
