When production volumes rise and tolerances tighten, manufacturers need a machining process that delivers accuracy, speed, and cost efficiency. That’s where multi spindle screw machining stands out as one of the most effective solutions.
At Emjac Screw Products Ltd., a Toronto based screw machine company with more than 50 years of experience, we specialize in producing high volume precision turned parts using Davenport, Acme Gridley, and Brown & Sharpe equipment. Here’s why multi spindle screw machining remains a cornerstone of modern manufacturing.

⚙️ What Is Multi Spindle Screw Machining?
Multi spindle screw machines are high speed, mechanically driven machines designed to produce large quantities of small, precision machined components. Unlike single spindle machines, which work on one part at a time, multi spindle machines can machine six or more parts simultaneously.
Each spindle performs a different operation — drilling, turning, threading, or forming — and rotates the part from station to station until it is complete. This allows for:
• Extremely fast cycle times
• High repeatability
• Lower cost per part
• Consistent quality across large production runs
For industries that require thousands or millions of identical components, multi spindle screw machining is unmatched.

🔩 Why Manufacturers Choose Screw Machining
1. High Volume Efficiency
Multi spindle machines excel at producing large quantities of parts quickly. Because multiple operations occur at once, cycle times are significantly shorter than CNC machining for similar parts.
2. Tight Tolerances
Despite their speed, screw machines deliver impressive accuracy. At EMJAC, we routinely achieve tolerances down to ±0.001 in, depending on material and geometry.
3. Cost Effective Production
Once a job is set up, multi spindle machines run efficiently with minimal downtime. This reduces labor costs and lowers the overall price per piece — a major advantage for OEMs and high volume manufacturers.
4. Versatility in Materials
Screw machining works exceptionally well with:
• Brass
• Steel
• Stainless steel
• Aluminum
• Copper
• Specialty alloys
This flexibility makes it ideal for components used in automotive, hydraulic, electrical, and industrial applications.
5. Reliable Repeatability
For companies that require consistent quality across long term production programs, screw machining provides dependable, repeatable results.
