The difference bwtween hydraulic spline rolling machine and CNC spline rolling machine


DAASCNC has a vertical, horizontal, oil pressure-driven, servo-driven full series of various kinds of spline rolling machines, with many years of manufacturing and service experience, in order to make users in the selection can distinguish good from bad, we will list all kinds of CNC spline rolling machine-related information, so users can select the model rationally according to the demand of the target parts. Of course, all comparisons can only be made between horizontal machines and vertical machines, hydraulic machines, and servo machines of the same specification. Meanwhile, due to our limited experience, we hope that our peers can correct us where we are shallow.

Advantages of Hydraulic drive & CNC Spline Rolling Machine

Hydraulic Spline Rolling Machine

1) The oil cylinder drive is adopted, because there is no mechanical friction ( compared with ball screw), the drive has a long life and requires little maintenance.

2) Due to the good overload performance of the hydraulic drive, it is easy to realize when the processed parts are large or under certain conditions need to overload.

3) When the oil pressure design is reasonable, the alternating stress has incomparable driving stability in bearing of rolling especially when the large modulus is formed.

4) Due to the characteristics of the oil pressure decelerating when it encounters resistance, in some cases, it is advantageous to reduce the damage of the rolling die.

5) Relative economic.

CNC Spline Rolling Machine

1) There is no oil station as the driving source, the surrounding environment of the equipment is clean and the floor area isreduced.

2) General working noise does not exceed 40 decibels, basically no noise pollution.

3)The rolling process can be programmed to obtain the appropriate speed curve.

4)The servo drive can save energy when the machine is not working (however, as the rolling machine is a kind of high-frequency production machine, this advantage is not obvious except for a long standby time).

In the following case, it is recommended that the user choose the hydraulic rolling machine, on the contrary, the servo rolling machine can be chosen:

1) The target part belongs to the category of large modulus, large number of teeth, long spline and high hardness.

2) No mind for floor area.

3) Can accept the oil pressure type may be a small amount of leakage and the existence of 60 decibels of noise.

4) For the purchase and maintenance cost requirements are relatively economical.

5) When asking for models larger than 36 inches (when more than 36 inches, the vertical machine has been difficult to achieve, horizontal machine screw transmission length is limited).


1. Each has its advantages Whether it is a vertical, horizontal, hydraulic, or servo rolling machine, the main differences are in the floor area, easy to operate, processing capacity, equipment durability, maintenance, environmentally friendly, and different models have their advantages.

2. Design details and process capacity determine the machining accuracy. No matter what type of machine, or driving mode, in addition to the above differences, its impact on product precision and processing efficiency is not very obvious, in the range of machine load of the product processing precision depends on the design details of the machine and the ability of the manufacturer.

3. Horizontal type can cover all specifications of vertical type. Non-automatic vertical models under 24 inches have the advantages of small footprint and convenient operation. Horizontal type can cover all specifications and functions of vertical type, whereas vertical type cannot.
