Proven Application Verticals
| Valve Special Machine | Wheel Hub Special Machine |
|---|---|
| The Stallion Valve Special Series is a one-of-a-kind vertical turning and milling composite that completes machining of valve bodies, bonnets and brackets in a single setup. Turning, milling, drilling, boring and tapping are all finished under one datum reference — eliminating the cycle time and labour involved between operations. Engineered for serial valve production where consistency and throughput define cost-per-piece. | Vertical-axis composite machine engineered specifically for automotive wheel hub production — combining wheel hub turning and bolt-hole drilling in a single setup. Outperforms a conventional VTL plus drilling machine combination on cycle time, dimensional consistency between the rim seat and bolt pattern, and per-hub labour cost. Built for serial passenger car, commercial vehicle and off-highway hub production lines. |
| Brake Disc Special Machine | Brake Drum Special Machine |
|---|---|
| Dedicated brake disc machining platform engineered for OEM brake disc production lines — with twin-tool configurations that machine both braking faces concurrently in a single clamping. Significantly compresses the per-disc cycle time that defines cost-per-piece in volume brake disc manufacturing, and integrates naturally with downstream balancing for inline production cells. | Heavy-duty vertical-axis brake drum platform engineered for commercial vehicle, off-highway and rail brake drum production. Larger swing and turning depth than passenger-car platforms, with rigidity tuned for cast iron heavy cutting in production environments. |
| Steering Knuckle Special Machine | Brake Drum Special Machine |
|---|---|
| Multi-face machining platform engineered around the geometric complexity of steering knuckle components. Combines the turning, milling and drilling operations a knuckle requires onto one platform — eliminating multiple re-fixturing setups and the dimensional drift that accumulates across machines. | High-performance double spindle vertical machining centre engineered for parallel production — two identical workpieces machined simultaneously in one cycle, with extended X-axis travel for longer components. A single platform that effectively does the work of two conventional VMCs in the same floor footprint. |
| Multi-Spindle & Twin-Turret Configurations |
|---|
| Beyond the proven application verticals, Stallion engineers multi-spindle (2, 3, 4, 5 spindle) and twin-turret lathe configurations for high-volume cylindrical and prismatic components. Throughput multiplied per cycle without proportional increase in floor space, operator load or fixture cost. |
Frequently Asked Questions
Why prefer a Valve Special Machine over a conventional VMC or VTL?
A conventional VMC or VTL forces valve body machining through multiple setups across multiple machines — each re-fixturing adds tolerance stack-up, handling time and labour cost. The Stallion Valve Special Machine completes turning, milling, drilling, boring and tapping under one datum reference in a single clamping, removing those penalties. For serial valve production, the cycle time and consistency gains translate directly into lower cost-per-piece.
Why prefer a Brake Disc Special Machine over a standard VTL?
Standard VTLs are designed for versatility across many disc-shaped components. The Stallion Brake Disc Special Machine is purpose-built around the brake disc cycle — with twin-turret options that engage two cutting tools concurrently on the workpiece. In OEM brake disc lines where the per-disc cycle time defines plant economics, the dedicated platform consistently outperforms a general-purpose VTL on throughput and per-piece cost.
Why prefer a Wheel Hub or Knuckle Special Machine over a general-purpose CNC?
Both wheel hubs and steering knuckles have geometric and production-volume characteristics that punish general-purpose machine architectures. Wheel hubs need turning AND bolt-hole drilling — a standard VTL handles only the turning, forcing a second machine, second setup and second source of dimensional drift between the rim seat and bolt pattern. Knuckles need multi-face geometry handling that forces re-fixturing across machines. A purpose-engineered Stallion SPM combines these operations onto one platform — the standard architecture for OEM-scale production of these components.
What does a double spindle VMC offer over a single spindle machine?
A double spindle VMC machines two identical workpieces in parallel in a single cycle — directly doubling per-cycle throughput without doubling floor space, operator load or fixture cost. For high-volume small and medium components, the double spindle architecture is the most cost-effective way to scale production capacity. The long-stroke variant extends this advantage to larger workpieces.
Which components are best suited to Stallion Special Purpose Machines?
Stallion's proven SPM verticals are valve bodies (gate, ball, control, check), automotive wheel hubs, brake discs, brake drums, steering knuckles, and high-volume components suited to double spindle or multi-spindle production. Beyond these, custom SPM and multi-spindle / twin-turret configurations are engineered around the customer's specific component family. Reach out for a detailed catalogue and application discussion.
