Vacuum Tables
Q: What’s the difference between a grid vacuum table and a hole grid table?
Grid vacuum tables have continuous grooves with sealing cords—ideal for flexible setups. Hole grid tables use fixed suction points, great for repeatable positioning or jigs and softer materials.
Q: Can vacuum tables be used for wet machining?
Yes, with the right setup. For applications involving coolant, we recommend using a liquid separator. Let us know your specs and we’ll suggest the best system.
Q: Which vacuum pump should I choose?
It depends on your table size, part material, and sealing conditions. Our vacuum pump guide helps match the right pump to your needs—or just contact us for help.
Q: Are heated vacuum tables available?
Yes, we offer heated (and cooled) versions upon request, especially for composite and 3D printing applications.
Q: What makes the HT-Series heated vacuum tables unique?
A: The HT-Series combines precision vacuum clamping with accurate PID-controlled heating, ensuring uniform temperature and stable workholding even in demanding CNC or lamination applications.
Q: What’s the difference between entry-level and production-grade vacuum tables?
A: Entry-level vacuum tables are often designed for flexibility and basic applications, while production-grade systems focus on repeatability, controlled sealing, and predictable holding behavior in daily operation.
Q: When should I upgrade my CNC vacuum table instead of replacing it?
A: If your current setup struggles with holding force, leaks, or inconsistent machining results, it may be time to upgrade your system. In many cases, optimizing your setup is more effective than replacing it entirely.

Customization
Q: Can I order a vacuum table or T-slot plate in a custom size?
Absolutely. We offer custom dimensions, suction zones, hole patterns, bushings, and heated options. Send us your drawing or machine specs to info@worldofclamping.com - we’ll handle the rest.
Q: What’s the largest size you can provide?
One-piece plates are available up to 3000 x 1500 mm. Larger sizes can be configured modularly for your application.
T-Slot Plates
Q: What materials do you offer for T-slot plates?
We supply plates made from high-quality tooling steel (C45/1.1730) or cast aluminum EN AW-5083. Your choice depends on the required load capacity and machining accuracy.
Q: Are the T-slot plates surface ground?
Yes, most of our T-slot plates are surface ground to ensure optimal flatness and precision.
Q: Do you offer metric and inch versions?
Yes. T-slot spacing, thread sizes, and dimensions are available in both metric and inch configurations.
Setup & Operation
Q: How do I connect a vacuum pump to the vacuum table?
Each table includes standard connection ports. We also supply matching hoses, manifolds, and fittings. If you're unsure, we’ll guide you through the setup.
Q: Can I use my own vacuum pump?
Yes, as long as it meets the required vacuum level and flow rate for your table size. We’re happy to check compatibility for you.
Q: What accessories do you recommend?
Typical accessories include sealing cords, soft PVC mats, adapters, and liquid separators. We can recommend what you need based on your setup.
Orders & Delivery
Q: What’s your typical lead time?
In-stock items in Wisconsin ship within 2–3 business days. Made-to-order or custom items from Germany usually take 2–6 weeks.
Q: Can I request a formal quote?
