Double-Servo Torsion-Bar CNC Press Brake for Batch Production
TPBS sits between basic NC machines and high-end electro-hydraulic or full electric press brakes. It keeps the familiar torsion-bar structure, while adding double servo concepts and CNC control so that workshops can run faster, more repeatable batch jobs on standard parts.
Typical users include electrical cabinet manufacturers, enclosure and box producers, door and frame workshops and general fabrication factories that repeat similar parts every day. TPBS delivers higher throughput and more stable angles than entry-level NC machines, while staying easier to justify than the highest-end bending routes.

TPB Series: Find the Right Fit
Two TPB press brake series, each positioned for a different production level.
TPB NC
A practical NC press brake with simple E21/E200 control for workshops stepping up from manual bending.
- Small to medium batch jobs
- Simple angle and position programming
- Budget-conscious workshops
TPBS Servo
A double-servo torsion-bar CNC press brake for batch production — faster cycles and better repeatability.
- Higher-volume batch production
- Improved cycle time efficiency
- Better angle consistency
Choose TPBS if...
- Best for batch production of standard parts — TPBS is ideal if you run repeated cabinets, enclosures, brackets or similar parts every day. Double-servo concepts and CNC control make batch jobs more efficient and repeatable.
- Need better efficiency than basic NC machines — If you are currently using manual or basic NC press brakes and want noticeably faster cycle times with more consistent angles, TPBS offers a practical step up.
- Budget-conscious about high-end CNC investment — TPBS sits between NC and high-end electro-hydraulic machines. It gives you servo-level efficiency and CNC repeatability without the full investment of premium platforms.
- Want torsion-bar simplicity with CNC capability — If your team is familiar with torsion-bar press brakes and you want to add structured CNC programming and servo-driven positioning, TPBS is a natural upgrade path.

TPBS Servo CNC Press Brake FAQ
- TPBS adds double-servo concepts and CNC logic on top of the torsion-bar base, so repeated parts can be bent faster and with more stable angles than on basic NC machines. It is designed as a mid-level, high-value choice for workshops that run batch jobs every day.
- Yes. TPBS is particularly suitable for cabinets, enclosures, electrical boxes, brackets and similar parts that repeat frequently. Once a CNC program is set and verified, operators can reuse it to keep bending results consistent from batch to batch.
- TPBS uses a practical CNC controller working together with a servo-driven backgauge concept. Exact controller models and axis arrangements are confirmed during quotation based on your material, thickness and typical part geometry.
- Yes. TPBS can be supplied with electric or manual crowning concepts and optional safety upgrades such as light curtains, laser protection and rear guarding, depending on your workshop standards and budget.
- TPBS is positioned exactly in that space. It is usually a good choice when you need better efficiency and repeatability than basic NC machines, but do not yet want to move into the investment and complexity level of high-end electro-hydraulic or full electric press brakes.
