HIWIN Rolled Ballscrews are made by the rolling process of the screw spindle instead of the grinding process. Rolled ballscrews not only have the benefit of low friction and smooth running for the linear feed system compared with traditional screws, but also can be supplied by quick stock delivery and lower production price. HIWIN uses the most advanced technology in the ballscrew rolling process. By maintaining the homogeneous manufacturing procedure of selecting materials, rolling, heat treating, machining and assembling. In general, rolled ballscrews use the same preload method as the precision ground ballscrews, except that there are some differences in the lead error definition and the geometric tolerance. The grade of the rolled ballscrews can be ordered according to the same nut dimension of the precision ground ballscrew. If the ends of the spindle are unmachined, the geometric tolerance does not apply. The production scale of each type of the ballscrews and the accuracy classification are described in the following sections (the unit of length used is in mm).   Table 7.1 gives the lead accuracy of the precision rolled ballscrews. The lead accuracy is measured by the accumulated lead error of any portion of 300 mm in length. The maximum axial plays of the precision rolled ballscrews are shown in Table 7.2. These ballscrews can be preloaded as the precision ground ones. The categories of the precision rolled ballscrews are listed in Table 7.3. Fig. 7.1 show the geometric tolerance of the general rolled ballscrews. has a variety of the precision rolled ballscrews for our customers’ urgent requirement.

The APEX servo gearbox has been designed for direct attachment to popular servomotors. The power is transmitted from the motor to sun gear. The sun gear drives three planet gears, which are contained within an internal toothed ring gear. The planet gears are mounted on the planet carrier with double wall supports. The planet carrier is part output shaft. So when the sun gear rotates, it drives the three planet gears inside the ring gear. As planet gears rotate with carries and automatically the output shaft rotates. Due to the load sharing into multiple tooth contacts, the gearbox provides the highest torque and stiffness for a given envelope. The other significant advantages are simple and efficient lubrication and a balanced system at high speeds. The balanced kinematics and the associated load sharing makes the gearbox truly  ideal for servo applications.

Metal Bellows couplings – because of their extremely high torsional stiffness and both angular and axial flexibility – are installed wherever powers, up to the highest levels, have to be transmitted between shafts, highly efficiently and absolutely backlash-free. This means that they effectively compensate for manufacturing variations in drive or support shaft bearings, both for angular and axial misalignment, with only very low restoring forces; thereby extending bearing life considerably.In today’s ever increasing drive systems demands, Metal Bellows couplings prove an indispensable connection component. Their wide range of different shaft fixing versions; whether       by bore & keyway, with two locking set-screws, 1 over the key, the other at 120° onto the shaft, or by ‘key-less’ bore only, with part axial-split & radial-cut hubs ‘all-round clamping’ via single socket-head screw mounted in drilled, tapped & counter bored hole along a chord line across the split in the hub, or . via protruding expanding mandrel into hollow shafts, or by the ‘key-less’ bore only, ‘clamping’ compression imposed, from tightening multiple-screws axially, across conical mating ring/tapered surface hubs, or by simple flange bolting connection,the installation options are enormous.       The coupling principle offers the advantage of very simple & easy handling and operation. In most variations it comprises of only a single component.With the key-less, split-/clamping- hub designs, drive shafts suffer no damage, with the elimination of any possibility of rubbed ‘flats’ from abrasion appearing in any form, on dismantling or even during operation. The torque to be transmitted is more evenly distributed, around the whole shaft surface, as opposed to only one side of the keyway. There is no possibility of fretting corrosion. Life span is substantially improved and it is maintenance-free.The bellows part of the coupling is made from stainless steel, whilst hubs made from aluminium alloy are ‘Loctite’ glued to each end. However, with the larger hub sizes (from KB4/60 upwards) material changes to steel and they are soldered, or welded to each end of the bellows.Combining all these positive qualities makes the bellows coupling one of the most popular and proven shaft connectors found, particularly, in the industrial sectors of NC machines, Servo Drives, Packaging Machines, Linear Devices, Machine Tools, Pulse Generators (encoders, etc.) and Robot Control Drives and also in practically every other area of the dynamics, even under the most difficult environmental conditions.       Specific Feature:A particular feature of the metal Bellows Couplings arises from their meticulous manufacturing process, where guaranteed high concentricity of assembled components is assured, because every single coupling is ‘centered’ at the jointing assembly, on a mandrel. The rotational concentricity is then measured (for high accuracy) again at the final inspection stage

A Linear guide way allows a type of linear motion that utilizes rolling elements such as balls or roller. By using recirculation rolling elements between the rail and the block, a linear guide way can achieve high precision linear motion. Compared to a traditional slide, the coefficient of friction for a linear guide way is only 1/50th. Because of the restraint effect between the rails and the blocks, linear guide ways can take up loads in both the up/down and the left/right directions. With these features, linear guide ways can greatly enhance moving accuracy, especially, when accompanied with precision ball screws.     Advantages and Features of Linear Guideways   (1) High positional accuracyWhen a load is driven by a linear motion guideway, the frictional contact between the load and the bed is rolling contact. The coefficient of friction is only 1/50th of traditional contact, and the difference between the dynamic and the static coefficient of friction is small. Therefore, there would be no slippage while the load is moving.   (2) Long life with high motion accuracyWith a traditional slide, errors in accuracy are caused by the counter flow of the oil film. Insufficient lubrication causes wear between the contact surfaces, which become increasingly inaccurate. In contrast, rolling contact has little wear; therefore, machines can achieve a long life with highly accurate motion.   (3) High speed motion is possible with a low driving forceBecause linear guideways have little friction resistance, only a small driving force is needed to move a load. This results in greater power savings, especially in the moving parts of a system. This is especially true for the reciprocating parts.   (4) Equal loading capacity in all directionsWith this special design, these linear guideways can take loads in either the vertical or horizontal directions. Conventional linear slides can only take small loads in the direction parallel to the contact surface. They are also more likely to become inaccurate when they are subjected to these loads.   (5) Easy installationInstalling a linear guideway is fairly easy. Grinding or milling the machine surface, following a recommended installation procedure, and tightening the bolts to their specified torque can achieve highly accurate linear motion.   (6) Easy lubricationWith a traditional sliding system, insufficient lubrication causes wear on the contact surfaces. Also, it can be quite difficult to supply sufficient lubrication to the contact surfaces because finding an appropriate lubrication point is not very easy. With a linear motion guideway, grease can be easily supplied through the grease nipple on the linear guideway block. It is also possible to utilize a centratized oil lubrication system by piping the lubrication oil to the piping joint.   (7)  InterchangeablyCompared with traditional boxways or v-groove slides, linear guideways can be easily replaced should any damage occur. For high precision grades consider ordering a matched, non-interchangeable, assembly of a block and rail.

4.3 Accuracy Grade of HIWIN Ballscrews   Precision ground ballscrews are used in applications requiring high positioning accuracy and repeatability, smooth movement and long service life. Ordinary rolled ballscrews are used for application grade less accurate but still requiring high efficiency and long service life. Precision grade rolled ballscrews have an accuracy between that of the ordinary grade rolled ballscrews and the higher grade precision ground ballscrews. They can be used to replace certain precision ground ballscrews with the same grade in many applications   Accuracy grade   There are numerous applications for ballscrews from high precision grade ballscrews, used in precision measurement and aerospace equipment, to transport grade ballscrews used in packaging equipment. The quality and accuracy classifications are described as follows: lead deviation, surface roughness, geometrical tolerance, backlash,drag torque variation, heat generation and noise level.   HIWIN precision ground ballscrews are classified to 7 classes. In general, HIWIN precision grade ballscrews are defined by the so called “V300p” value see Fig 4.12 and rolled grade ballscrews are defined differently as shown in Chapter 7. Fig. 4.12 is the lead measuring chart according to the accuracy grade of the ballscrews. The same chart by the DIN system is illustrated in Fig. 4.13. From this diagram, the accuracy grade can be determined by selecting the suitable tolerance in Table 4.2. Fig. 4.14 shows HIWIN’s measurement result according to the DIN standard. Table 4.2 shows the accuracy grade of precision grade ballscrews in HIWIN’s specification.The relative international standard is shown in Table 4.3.The positioning accuracy of machine tools is selected by ep value with the V300p variation. The recommended accuracy grade for machine applications is shown in Table 4.5. This is the reference chart for selecting the suitable ballscrews in different application fields.   Axial play (Backlash)   If zero axial play ballscrews (no backlash) are needed, preload should be added and the preload drag torque is specified for testing purpose. The standard axial play of HIWIN ballscrews is shown in Table 4.4.For CNC machine tools, lost motion can occur in zero-backlash ballscrews through incorrect stiffness. Please consult our engineers when determining stiffness and backlash requirements.   Geometrical tolerance   It is crucial to select the ballscrew of the correct grade to meet machinery requirements. Table 4.6 and Fig 4.15 are helpful for you to determine the tolerance factors, which are based on certain required accuracy grades.
