What is a THK Guideway?

A guiderail or linear guide is an essential component in any machine that requires precise and smooth linear motion. A THK Guideway is a linear motion guide produced by THK Co., Ltd, Japan. THK's high-precision and high-quality linear motion systems set the standard for the global market. They are available in different shapes such as HSR, HRW, SSR, SRS, RSR, and SCR, which cater to various industrial applications. Each type of THK Guideway has its unique features, sizes, specifications, and application.

Features and Advantages of THK Guideways

1. High-Precision Performance

THK Guideways are renowned for their high-precision performance, which is due to their precisely finished surfaces and tight tolerances. The polished and hardened surface of the guideways ensures smooth movement and excellent accuracy during linear motion, making them the ideal choice for high-precision machinery such as CNC machines, measuring instruments, and semiconductor manufacturing equipment.

2. High Load Capacity

THK Guideways can carry heavy loads and still maintain a high level of precision. The load capacity is due to the use of hardened steel materials and the design of the ball and roller bearings. The high load capacity makes THK Guideways the perfect choice for heavy-duty applications such as machine tools and assembly lines.

3. High Rigidity

THK Guideways have high rigidity due to the combination of steel and rolling elements, which ensures that they can withstand high moments and torsions. High rigidity is essential in high-precision applications that require minimal deflection, such as pick and place robots.

● Introduction

THK guideways is a steel ball placed between the slider and the guide rail, which makes the sliding friction between the slider and the guide rail into rolling, the difference between the static friction force is small, and the follow-up is excellent. It enables the load platform to move linearly with high precision along the guide rail. The guide rail is used to support and guide the moving parts, and perform reciprocating linear motion in a given direction. The linear guideways has high positioning accuracy. When the linear guide rail is used as a guide, the friction coefficient is reduced, high positioning accuracy and repeat positioning accuracy can be achieved, high precision can be maintained for a long time, and the driving force can be reduced, which is suitable for high-speed motion. The rails have good interchangeability and are easy to assemble, disassemble and maintain. Both ends of the slider are equipped with sealed end caps, which have good dustproof performance. The lubricating structure of the guide rail is simple, and the slider is equipped with an oil injection hole, which can be directly injected with grease by the oil injection gun. It can also be connected to the oil supply pipe to automatically lubricate the machine.

THK guideways are mainly used in the fields of automated machinery, machine tools, bending machines, laser welding machines, etc.

● Bearing Series

The type of the linear motion guideways is SHS series.

● Production Details

◆ The mechanism of grinding burns

In grinding, bearing rings are plastically deformed due to the cutting, characterization and friction of abrasive particles on the workpiece, and internal friction is generated by the relative displacement of metal molecules inside the workpiece, when grinding wheels are cut, the speed is very high relative to the workpiece, and there is intense external friction with the surface of the workpiece, and because Because the cutting of each abrasive is instantaneous, its heat generation is also instantaneous, and it cannot be dispersed in time, so the instantaneous temperature in the grinding area is relatively high, generally reaching 800~1500°C. If the heat dissipation measures are not good, it is easy to cause burns on the surface of the workpiece, that is, secondary quenching and high-temperature tempering occur on the surface of the workpiece (usually dozens to hundreds of microns), destroying the microstructure of the surface of the workpiece. Severe burns can be seen from the naked eye, with scorched yellow or black oxide film on the surface, minor burns can only be observed by diluted acid solution, and the burn site is black, burns will reduce the service life of the workpiece.

◆ Super fine grinding

Ultra-precision grinding is a small grinding speed (15-18m/s) with high-quality fine-grained grinding wheels (the binding agent can be resin, rubber or re-graphite filler) and finely trimming to carry out micro-cutting and friction and polishing of the machining surface with appropriate contact pressure with good isometricity and micro-edge. Ultra-precision grinding obtains a low roughness value on the working surface, with a Ra value of 0.012~0.10um.

Ultra-fine grinding does not have a metamorphic layer caused by grinding heat, and it has a good effect in improving the shape and position error of the workpiece, but the surface rippleness and other circular errors are not as good as hyper-precision machining. In addition, ultra-precision grinding productivity is low, and there is no special automatic grinder. It can only be processed in precision bearing grinders. Generally, ultra-precision grinding is only used when machining precision and ultra-precision bearings.

● Demagnetization Process

The demagnetization of bearing parts generally adopts the AC demagnetization method, that is, the bearing parts with residual magnetism are subjected to an increasing amplitude and changing direction in the alternating magnetic field (produced by the AC coil circuit), thus reducing the residual magnetism on bearing parts to a certain minimum. The amplitude of this demagnetized magnetic field must be large enough, so that the magnetic domain in the bearing material can overcome the highest barrier encountered and realize the reorientation of the magnetic moment. The attenuation of the amplitude should be as slow as possible. Otherwise, some residual magnetism will be retained, and the ratio of two adjacent times should preferably be 1.36~1.39.
