In a typical APC device for a lathe, a setup station for workpiece centering is required. In this case, the setup station requires a rotational accuracy comparable to that of the main machine. The structure of the bearings for turning and load support, as well as the method of rotational drive, are important points. [Key Points] - A gear drive system requires high-precision large-diameter gears, which increases costs. - A chain drive system (pin-gear method) has significant backlash, necessitating a separate positioning device. - The rotational drive source can use a general-purpose geared motor in conjunction with an inverter. - Vibration in the drive unit is undesirable, as it manifests directly as vibration in the workpiece during centering. *For more details, please refer to the PDF document or feel free to contact us.*

A linear guide, when translated literally, means "linear motion guide" and is a mechanical component that allows smooth movement without play in the direction of the rail using a smooth return cap. Its structure is similar to that of bearings, featuring rolling motion with internal balls, which provides smoothness and low friction characteristics. If the equipment selection is not made according to the installation environment of the machinery, it can lead to early failure or damage of the device. I have heard that because ball retainers tend to allow foreign objects to remain inside the guide block, using a total ball type with grease lubrication to expel foreign objects from the guide block is one method. *For more details, please refer to the PDF materials or feel free to contact us.

Here are some key points regarding the design of cable carriers. When installing wiring and piping in moving parts, many devices use cable carriers. This helps prevent multiple wiring and piping from interfering with the equipment, allowing for smooth movement and providing protection for the wiring and piping. However, using them does not mean that problems will not occur. In high-speed moving devices, interference within the cable carrier can lead to premature wear and wire breakage, so caution is necessary. 【Design Points】 - Set the bending radius of the cable carrier (beyond the specifications of the inserted cables and piping) - Ensure the occupancy rate of the cable carrier (60% or less) - Secure the wiring and piping at both ends - If the outer diameters of the inserted items differ significantly, separate mixed wiring such as air hoses with partition plates *For more details, please refer to the PDF document or feel free to contact us.

This time, we will introduce friction fasteners that connect shafts and hubs, marketed under names such as Power Lock and Mecha Lock by manufacturers, without the use of keys. The principle of fastening involves the inner and outer rings being in contact with each other at a taper, and by tightening the lock bolt, a strong clamping force (frictional force) is generated, securing the shaft and hub together. There are various types available to suit different applications, so caution is necessary when using them. 【Points】 ■ Presence or absence of centering function ■ Whether there is movement of the hub in the axial direction when tightening the lock bolt ■ Usable even if the shaft has a keyway ■ Do not use molybdenum-containing grease or oil with extreme pressure additives ■ Tightening of the lock bolt should be done using a torque wrench, adhering to the specified torque *For more details, please refer to the PDF document or feel free to contact us.

Various actuators are used in the composition of mechanical devices, and this time we will introduce a double-acting power cylinder. It is a device that converts the pressure energy of a fluid into mechanical energy of linear motion. When the pressurized fluid is directed into the cylinder chamber and acts on the piston surface, a force is applied to the piston, which is calculated by (area of the surface where pressure acts) × (pressure). If a heavy object is connected to the piston rod, it can move that heavy object in a linear direction. 【Double-acting Cylinder Structure Diagram】 ■ There are inlet and outlet ports for the working fluid on both sides of the cylinder, and the direction of fluid flow is changed by a directional control valve to extend and retract the cylinder. * For more details, please refer to the PDF document or feel free to contact us.

Recently, devices using servo motors have become more common even in peripheral equipment for machine tools. When designing devices that use servo motors, it is necessary to select parameters such as acceleration and deceleration time, cycle time, and inertia ratio, in addition to torque and rotation speed. If the selection is incorrect, it can lead to control alarms, rendering the device inoperable. Although manufacturers provide technical calculations, the lack of standardized notation among companies makes it quite difficult for us designers to perform the selection calculations, which can be a headache. *For more details, please refer to the PDF materials or feel free to contact us.*
