1️⃣. Consultation and Coordination

When you need to purchase ball screws, linear guides, ball nuts, linear blocks, or Optical Shafts you contact us via our official website, WeChat, phone, or visit our factory-we will assign you a dedicated technical engineer with over five years of industry experience, rather than a general customer service representative.

We will listen carefully to your needs and gain a detailed understanding of:

• Your equipment type (e.g., CNC machine tools, automated equipment, 3D printers, testing instruments, etc.)
• Specific operating parameters (load capacity, operating speed, travel distance, frequency of use, operating environment)
• Precision requirements (e.g., C3/C5/C7 grade ball screws, standard/precision grade linear guides)
• Installation size constraints and compatibility with existing equipment
• Expected delivery time and budget range

Even if you don't have a specific model in mind yet, we'll provide you with free preliminary recommendations based on your actual application scenario to help you avoid common issues such as "spec mismatches" and "over-purchasing."

2️⃣. Customized Solutions and Transparent Quotes (Provided within 24 hours)

Based on your requirements, our technical team will provide you with a customized solution and a detailed quote within 24 hours. We never provide "vague quotes" or have "hidden costs."

The proposal includes:

• Complete model numbers, specifications, and material descriptions for recommended products (e.g., 45# steel, GCr15 bearing steel)
• Key technical specifications such as precision grades, preload methods, and dust protection ratings
• Recommendations for compatible accessories (e.g., nut seats, support brackets, couplings, dust covers)
• Estimated service life and key points for routine maintenance
• Cost-effectiveness comparisons of different configurations to assist with your selection

The quotation clearly specifies:

• Unit price, total price, and quantity
• Packaging fees and shipping costs (specifying whether shipping is included)
• Clear production lead time and delivery date

If you have any questions about the proposal or quote, our engineers are always available to assist you and will revise the proposal free of charge until it fully meets your requirements.

3️⃣. Order Confirmation and Contract Signing

Once you have confirmed the proposal and quotation, we will enter into a formal purchase and sale contract with you to clarify the rights and obligations of both parties. The contract will specify the following details:
 

• Product model, specifications, quantity, and accuracy grade
• Delivery date, delivery location, and shipping method
• Payment method and payment schedule
• Warranty terms and after-sales service details
• Liability for breach of contract and dispute resolution procedures

Once you have made the advance payment, we will immediately generate a unique order number for you and arrange for production and stock preparation. After the order is confirmed, we will provide you with instructions on how to track the order status, allowing you to monitor the production progress at any time.

4️⃣. Standardized Production and End-to-End Quality Control

We are equipped with modern production facilities and state-of-the-art processing and testing equipment. We organize our production in strict accordance with the ISO 9001 quality management system to ensure that every product meets industry standards and your requirements.

During the production process, we conduct multiple rounds of rigorous testing on core components:
 

• Ball Screws: Lead accuracy inspection, thread raceway roughness inspection, shaft runout inspection, nut preload testing
• Linear Guides / Linear Blocks: Smoothness of operation testing, rated load testing, parallelism inspection, clearance inspection
• Ball Nuts: Ball circulation smoothness test, preload torque test, seal integrity test
• Optical Shafts: Surface hardness test (HRC 58–62), straightness test, surface roughness test (Ra ≤ 0.4 μm)

We will update you on production progress every Friday. If any unforeseen circumstances arise that may affect the delivery date, we will contact you three days in advance to discuss a solution.

5️⃣. Warehousing and Shipping

Once the product has passed final quality inspection, we will package it using professional industrial-grade packaging to ensure it remains undamaged during transit:

• All precision components are wrapped in multiple layers of rust-proof paper and bubble wrap.
• Long shaft products are secured in specialized paper tubes or wooden crates to prevent bending or deformation.
• The outer packaging is clearly labeled with the product model, quantity, recipient information, and instructions such as "Fragile," "Keep Dry," and "This Side Up."

Included with the shipment:

• Product certificate of conformity
• Factory test report
• Detailed installation and user manual
• Matching small accessories such as screws and nuts

We will select the most suitable shipping method based on your requirements. Immediately after shipment, we will send you the tracking number and a link to track your package, and we will monitor the shipping status throughout the process to ensure timely delivery.

6️⃣. Comprehensive Technical Support and After-Sales Service

Our service doesn't end with product delivery; we provide full-lifecycle technical support and after-sales service.

• We offer free video installation guides and phone technical support to help you resolve any issues encountered during installation.
• For complex installation scenarios, we can arrange for an engineer to provide remote video guidance.
• We provide a detailed daily maintenance manual to teach you how to properly maintain the product and extend its service life.

Warranty and Repair Services

• All products come with a 12-month free warranty (effective from the date of receipt).
• During the warranty period, if the product develops quality issues due to non-human factors, we will repair or replace it free of charge.
• After the warranty period expires, we offer lifetime repair services at cost price, charging only for parts and waiving labor fees.
