Six Key Points for Selecting the Drive Mechanism of High-Precision Dispensers: Matching Lead and Acceleration/Deceleration: For high-speed jets, select a large lead (10-20mm) to suppress vibrations, while for fine continuous dispensing, use a small lead (1-5mm) to enhance resolution and uniformity. Screw Precision and Preload Grade: Use C3 grade with light/medium preload to accommodate high precision in semiconductors, while optimizing the balance of cost and yield with C5 grade combined with double nuts or closed-loop control. Suppression of Micro Vibration on the Z-Axis: To prevent residual vibrations (stringing) caused by cantilever loads from valve weight, employ high-rigidity dual guides or preload-type micro linear guide bushes. Symmetry of Guides and Supports: Enhance the assembly concentricity of the fixed and support sides to eliminate periodic wave patterns (irregular thickness) in the dispensing line caused by rotational runout of the screw. Lubrication and Cleanroom Measures: Use low-dust lubricants such as fluorinated grease (PFPE) to prevent fogging of optical components and corrosion or seizing due to chemical solvents. Thermal Displacement Suppression Design: Mitigate thermal expansion and positioning errors caused by friction heat during 24-hour continuous operation, achieving both long lifespan and high precision.

Selection and Comparison Guide for HFB003 and HFB008 Vibrations and minor precision drifts of end effectors that occur during the trial operation of automated equipment are primarily caused by insufficient rigidity of the guide shaft holder. Although both models have similar appearances, their design philosophies and application areas differ significantly. HFB003 (Extreme Space Optimization): Minimizes the outer diameter and flange width of the main body, eliminating constraints in narrow spaces where motors and sensors are densely packed. It is optimal for micro-stroke and small precision mechanisms, including very small diameters (less than ∅8), and primarily adopts two-hole fixation for medium and small sizes. HFB008 (Dynamic High Rigidity): Expands the outer shape and base span for medium to heavy loads. By increasing the thickness of the boss section, it maintains roundness of the inner diameter even under high tightening torque, preventing shaft binding, galling, and displacement due to impact. It fully adopts four-hole fixation from medium diameters, significantly enhancing resistance to tipping and torsional rigidity. Even in aluminum, it demonstrates sufficient thread support strength. Selection Points: If space-saving and low load are the top priorities, HFB003 is recommended. For dynamic mechanisms that experience frequent acceleration and deceleration or cantilever loads, HFB008 is recommended (Note: Since HFB008 has a larger outer dimension, it is necessary to check for 3D interference in advance).

KLF/KLT Ball Spline Selection Summary This is a summary of the features and differentiation of two models that achieve both linear motion and zero backlash torque transmission. KLF (Round Flange Type): By directly fastening with bolts, it evenly distributes moment loads and exhibits excellent dynamic rigidity. It is ideal for cantilever beams and lateral load environments, such as SCARA robots and wafer transport. KLT (Cylindrical Type): With key groove transmission, it aligns flush with the housing to eliminate interference. It is suitable for high-density parallel arrangements in extremely small spaces, such as multi-axis dispensing nozzles and mounting machines. Key Points for Selection If the shaft diameter is the same, the basic rated load and torque performance are equivalent, and both models are equipped with a structure to prevent steel balls from falling out during external tube extraction. If the pitch between adjacent shafts is less than "flange outer diameter + tool tightening clearance," choose KLT; if mounting rigidity is the top priority, select KLF.

**"A Storm of Food Waste Collection Will Hit in 2027" - A Crisis of Doubling Costs for Restaurants** In Taiwan, starting from January 2027, "feeding pigs with food waste" will be completely banned, leading to the disappearance of traditional low-cost collection routes. As a result, collection costs could soar to as much as 2,000 New Taiwan Dollars per barrel, placing a serious burden on businesses' backyards. With different disposal policies and subsidies (such as assistance for purchasing food waste processors) across municipalities, the main countermeasures available for business owners are as follows: 1. Passively accept price increases: Costs will rise indefinitely, and there will still be risks of odors and pests from a hygiene perspective. 2. Utilize public facilities: There is a need to align with scheduled collections, and issues with storage odors and transportation remain. 3. Introduce commercial food waste processors (source reduction on-site): While initial investment is required, collection costs can be reduced by over 80%, and waste can be converted into odorless dried residue on the same day. Additionally, recording decarbonization history through AIoT can be utilized for ESG reporting. In conclusion, on-site source reduction through commercial food waste processors is the only optimal solution to escape rising costs while achieving both environmental hygiene and sustainability.

Even if the shaft diameter and outer diameter match perfectly, differences in the internal mechanisms can lead to severe vibrations or locking (seizing) during the middle of the stroke if misidentified. HWLB-001 (Linear Bush Type - Infinite Stroke): This model features steel balls that continuously circulate within the track. It uses a POM holder, which excels in low noise and vibration absorption, making it ideal for general long-stroke linear reciprocating drives. The black resin holder is visible on the end face. HWLB-019 (Stroke Bush Type - Finite Stroke): In this model, the steel balls do not circulate, and the aluminum holder moves at half the shaft speed. While it has a maximum stroke limit (approximately 12 to 46 mm), it supports low friction and "linear + slight rotation," making it optimal for high-speed pressing and precision coating. Exceeding the tolerance can cause holder damage or shaft wear. [Appearance Identification and Environmental Compatibility] The appearance can be quickly identified by the holder on the end face (whether it is black resin or metallic aluminum color). For rust prevention and clean room environments, the all-metal HWLB-019 (SUS440C specification) is recommended to minimize dust generation.

■ Features and Differences MXL (trapezoidal teeth / 2.032mm) and S2M (arc teeth / 2.000mm) must not be mixed due to a pitch difference of 0.032mm. MXL: Low cost and easy to replace. Suitable for unidirectional constant speed and light load applications (e.g., office equipment, conveyors). Issues include backlash during reversal, stress concentration at the tooth base, and noise. S2M: Arc teeth distribute stress, achieving minimal backlash and high quietness. Designed for high precision and high-speed forward and reverse rotation (e.g., 3D printers, semiconductor inspection, medical devices). ■ Selection and Design Points Material: For high-speed lightweight applications, use "aluminum + hard anodizing"; for high torque, use "medium carbon steel + electroless nickel." Improving runout: Ghosting during reversal and trajectory disturbances can be resolved by switching to S2M. Preventing tooth skipping: Ensure engagement of 6 or more teeth, or adopt S2M and widen the belt. The content of this article is based on specific cases, and actual application effects may vary depending on industry characteristics, specification requirements, and usage environments.

Exhibition: Taipei Nangang Exhibition Center Hall 1, 1F K1222

Basic Comparison of T Shape and AT Shape T5 / T10 (Standard Type): The tooth root is thin and designed for light loads. Stress concentrates during sudden stops, making it prone to skipping and tooth breakage. AT5 / AT10 (High Load Type): The tooth root is thickened, improving torque transmission by 30-50% at the same pitch ratio. It is optimal for low backlash, high precision forward and reverse rotation, and multi-axis robots. Points for Operation and Improvement Mixing is not allowed: Due to different tooth groove shapes, belts and pulleys must be replaced simultaneously. Change to the same pitch is recommended: When torque is insufficient, changing to the same pitch AT5 to increase strength without altering installation space is optimal rather than enlarging to T10. Improving Precision: Reducing backlash prevents response delays during frequent forward and reverse rotations. *The content of this article is based on information from specific cases, and actual application effects may vary depending on industry characteristics, specification requirements, and usage environments. Please use it as reference information in advance.

■ Trapezoidal Teeth (General Torque: MXL/XL/L/H) Stress concentrates at the tooth root, making it prone to fatigue failure and tooth jumping during sudden starts or high loads, thus suitable for lightweight equipment under medium to low loads. ■ Arc Teeth (High Torque: S-M/P-M) Load is evenly distributed across the entire tooth surface, allowing for a torque capacity of more than twice. Deep grooves prevent tooth jumping during forward and reverse rotation, achieving low backlash and high rigidity, making it ideal for robots and CNC servo axes. ■ Practical/FAQ Points for Replacement: Changing from XL to S3M, etc., requires simultaneous replacement of the belt and pulley due to differences in pitch and tooth shape. S-M vs P-M: S-M is standard arc (quiet), while P-M is flat-top arc (for high-precision servo positioning). Additional Processing: When machining shaft holes and keyways, pay attention to coaxiality and shear strength to prevent wear due to eccentricity.

"Four Major Longevity Genes" of Precision Grade Guide Posts Abnormal noise and cumulative errors are caused by insufficient rigidity of the guide post assembly. Handway extends mold life by 3 to 5 times. 1. SUJ2 Bearing Steel: High fatigue strength that does not bend even after tens of millions of reciprocations. 2. Hardening & Sub-Zero: Hardness HRC 58-62. Residual stress is eliminated, resulting in zero dimensional change. 3. Super Finishing (<Ra 0.1): Minimizes friction heat. The black oxide coating absorbs oil film and prevents wear. 4. 2µm Tolerance & JIS Grade 5 Balls: "Zero Clearance" guidance with aluminum retainers and high sphericity steel balls. FAQ Highlights Q1. Reason for Sub-Zero: Prevents aging deformation and maintains 2µm tolerance. Prevents seizure due to thermal expansion. Q2. Effect of Black Oxide: The fine pores on the surface absorb and retain oil, maintaining the oil film even with high-frequency operation. Q3. Advantages of Aluminum Retainers: High rigidity without embrittlement from oil. Significantly reduces impact force due to inertia. Q4. Prevention of Eccentric Breakage: "Chamfer f8" makes centering easy. Confirms coaxiality and avoids excessive pushing.

Despite using the same drawings and contractors, there have been occasional issues with the assembly of retaining rings being either too loose or too tight. All parts passed inspection within the drawing dimensions (Φ20mm). The cause was that the drawings did not specify fit tolerance grades, leading to the dimensions of the shaft and hole drifting within the tolerance range, which caused the tightness to become erratic due to cumulative differences. To resolve this, it is necessary to specify tolerance grades during the design phase and to establish a range for tightness. Gap fit (H7/g6, etc.): The tolerance range of the shaft is below that of the hole, creating a gap. It can be disassembled without load. Suitable for rotating or movable parts and areas that are frequently disassembled. Interference fit (H7/k6, etc.): The tolerance ranges partially overlap, resulting in a very small gap or interference. It is assembled using press-fitting or light tapping, preventing misalignment with high precision. The drawings should include not only symbols but also the upper and lower limits of dimensional tolerances, which should be managed by the contractors. FAQ Q1: Mixing? Mixing different shaft stages of the same axis is possible depending on functionality. Q2: Readjustment? Disassembling an interference fit is not recommended as it can damage the surface and change the tolerances. A gap fit is recommended. Q3: What do the numbers mean? IT tolerance grades. The smaller the number (g6), the higher the precision and uniformity, but costs will rise.

In automated equipment, shaft collars are responsible for preventing parts from coming loose and for axial positioning. The standard products feature a precise "gap-fit" design that does not damage the rod and generates high holding power during set screw tightening. "End Face Squareness Geometric Tolerance" that affects precision and lifespan The end face squareness geometric tolerance on the drawing (0.02|A) is set to keep runout within 20 micrometers. Poor quality products that have not been inspected for geometric tolerance (with squareness exceeding 50 micrometers) generate diagonal force components, leading to bending of the guide rod and eccentric loads on the bearings. As a result, vibration and heat generation increase, significantly reducing the machine's MTBF (Mean Time Between Failures). Handway's Strengths We thoroughly manage geometric tolerances that comply with international standards and provide top-class products made from the following materials: S45C SUS304 Aluminum alloys, etc. Upgrades through additional processing For high-vibration environments, we recommend additional processing such as D-cuts or pilot hole machining on the rod. The tips of the set screws can mesh together, allowing for a reliable upgrade in fixation. For optimal solutions, please consult Handway.

In automated equipment, the stability of linear mechanisms affects the lifespan of the machinery. However, there are many cases where only the dimensions are prioritized when selecting linear shafts, overlooking the "depth of high-frequency hardening." Linear shafts are subjected to high-frequency rolling loads from steel balls, making it crucial to balance wear resistance and breakage resistance. The key to this is the "hard shell soft core" structure. The outer hardened layer prevents wear due to its high hardness (SUJ2: HRC58 and above, SUS440C: HRC56 and above), while the inner soft core absorbs shocks and prevents brittle fracture. The hardening depth is optimized to about 0.5 to 1.0 mm depending on the outer diameter. If it is too shallow, flaking can occur; if too deep, the risk of fracture due to reduced toughness increases. Additionally, selection must be based on dynamic loads and vibration environments, and secondary processing after heat treatment is not recommended as it can cause deformation and micro-cracks.

The shaft holder is a component that supports stable linear motion and axial loads. If the selection of materials and surface treatments is incorrect, it can lead to rust, contamination, and seizure. The characteristics of the five main standards are as follows: SS400 + Black Dye (Rust Prevention: Moderate): Forms an extremely thin chemical oxidation film. Maintains H7 tolerance without thickness variation. The matte black color is less reflective, making it ideal for AOI optical inspection. SS400 + ENP (Rust Prevention: Good): Nickel-phosphorus alloy layer is deposited through chemical reduction. Provides uniform coverage even in deep holes, with excellent hardness and wear resistance, making it ideal for humid environments. SUS304 Stainless Steel (Rust Prevention: Excellent): Coating is unnecessary due to a unique passive film. No peeling due to friction, making it an essential standard for clean rooms, medical applications, and food machinery. A6061 + Anodized (Rust Prevention: Good): Generates a hard ceramic layer. One-third the weight of steel, reducing motor load and increasing acceleration, making it ideal for EOAT. A6061 + Black Anodized (Rust Prevention: Good): Adsorbs black dye into fine pores for a matte finish. Balances lightweight design with low reflectivity, making it ideal for semiconductor inspection equipment.

In the design of precision machinery and micromechanisms, it is important to achieve optimal linear motion strokes within limited space. The selection of microcomponents significantly impacts not only size but also operational accuracy and maintenance cycles. To improve reliability, understanding the relationship between contact length (L1: guide bushing, L2: steel ball retainer) and stroke is essential. HEADWAY offers the following two types according to design needs. Open-type guide bushings ensure flexible strokes by maintaining L2≥L1, with S=2×(L2−L1). Closed-type guide bushings enhance stability with a structure where L1>L2, with S=2×(L1−L2). In terms of performance, they can handle high-frequency operations of 30 million to 50 million cycles, and the optimized steel ball circulation structure increases operational efficiency to about three times that of standard products. The low-wear design maintains a lifespan of 2 to 3 years, contributing to reduced maintenance costs. Additionally, the SUS440C stainless steel specification allows for compatibility with special environments such as oil-free (food industry), anti-volatile (optical equipment), and high vacuum (semiconductors). Selecting the appropriate guide bushing and adopting components based on actual measurement data are key to maximizing the accuracy and long-term productivity of the equipment.

Assembly troubles with positioning pins are largely due to the geometry of the ends. Choosing the appropriate chamfer (C face) or radius (R face) can make a significant difference in assembly efficiency and component lifespan. C face (Chamfer): Excellent for guiding initial contact and correcting position, it allows for smooth guidance. It reduces seizing and deformation, and minimizes positional misalignment during press-fitting. It pairs well with ANSI standard hardened steel, making it ideal for high-precision press fits and improving stability in automated lines. R face (Radius): The curved surface disperses stress, reducing the risk of damage to hole walls and fatigue cracks. It is suitable for ISO/DIN standard non-hardened stainless steel, and is ideal for slip fits, frequent assembly and disassembly, and use with soft materials like aluminum and plastics. It ensures durability and stability even with long-term use. Selection summary: For efficiency, choose C face; for durability, choose R face; for critical structural components or high-precision equipment, a combined design of C + R is appropriate.
