For heavy-duty turning, threading, and precision boring, any vibration or loss of center height can ruin a workpiece. The Wedge Type Quick Change Tool Post is universally recognized as the superior choice over traditional four-way posts and standard piston designs. When you lock the handle, an internal sliding wedge moves downward, pulling the tool holder tightly against the dovetail of the main block. This wedging action creates a solid, unified mass between the tool post and the holder, providing unmatched rigidity. Furthermore, it allows you to swap pre-set tools in seconds, returning exactly to your zero point every single time, drastically reducing setup times and increasing shop profitability.
0.0001" Repeatability: The precision-ground wedge and dovetail design guarantees that when you remove a tool holder and replace it, the cutting edge returns to the exact same position within 0.0001 inches (0.0025mm).
Superior Wedge Locking Mechanism: The sliding wedge pulls the holder inward and downward, providing significantly more clamping force and rigidity than a piston pushing outward. This makes it ideal for heavy roughing and interrupted cuts without chatter.
Permanent Height Adjustment: Each tool holder features a knurled thumb nut and locking stop screw. Once you set the cutting tool to the exact center height of your lathe spindle, it stays locked. Say goodbye to frustrating shims.
Universal Interchangeability: Our wedge tool posts and holders are fully compatible with industry-standard Aloris, Dorian, Phase II, and other brand wedge and piston-style tool holders of the same series (e.g., our BXA wedge post accepts any standard BXA holder).
Premium Hardened Steel: All components, including the main block, wedge, and tool holders, are machined from high-quality alloy steel, case-hardened, and precision-ground for long-lasting accuracy and wear resistance.
Direct Manufacturer Savings: Bypass trading companies and source premium, high-precision lathe tooling directly from our factory for highly competitive wholesale pricing.
Comprehensive Size Range: We manufacture the full spectrum of wedge tool post sizes to fit any manual or CNC toolroom lathe:
100 Series (AXA): For lathes with up to 12" swing.
200 Series (BXA): For lathes with 10" to 15" swing.
300 Series (CXA): For lathes with 13" to 18" swing.
400 Series (DXA): For lathes with 14" to 20" swing.
Complete Kits Available: We offer complete sets that include the main wedge tool post body and a selection of standard holders (turning/facing, boring, parting, knurling) to get your machine running immediately.
Strict Quality Control: Every tool post is rigorously inspected for dovetail accuracy, wedge smooth operation, and clamping repeatability before packaging.
Q1: Why should I choose a Wedge type over a Piston type tool post?
A: While both use the same dovetail tool holders and offer fast tool changes, the Wedge type is vastly superior in terms of rigidity and repeatability. The wedge pulls the holder tight against the block, whereas the piston pushes it away. If you do heavy roughing, interrupted cuts, or require the highest possible precision (0.0001" repeatability), the wedge type is the professional choice. Piston types are better suited for lighter duty or hobby lathes.
Q2: How do I choose the correct size (AXA, BXA, CXA) for my lathe?
A: The correct size is determined by your lathe's Swing Over Bed (the maximum diameter part it can turn). For example, if your lathe has a 12-inch swing, the AXA series is usually the best fit. If it has a 14-inch swing, the BXA series is recommended. Please consult our sizing chart or contact our sales team with your lathe model for a precise recommendation.
Q3: Can I use my old piston-style tool holders on this new wedge tool post?
A:Yes. The dovetail dimensions for the holders are standardized within each series. An AXA tool holder (whether it originally came with a piston or wedge post) will fit perfectly on an AXA wedge tool post, regardless of the brand, provided they follow the standard Aloris specifications.
Q4: How do I mount the tool post to my lathe's compound rest?
A: The tool post mounts via a central stud and a T-nut that slides into the T-slot on your lathe's compound rest. We provide a blank (unmachined) base T-nut with the kit. You or your machinist will need to mill this blank T-nut to the specific dimensions of your lathe's T-slot for a custom, rigid fit.
