The HX15ST Semi Auto Three-Knife Trimmer is professional post-press trimming equipment tailored for commercial digital printing production. It adopts manual book positioning mode, with front and side knives regulated by high-precision servo systems to achieve precise trimming dimension. Equipped with pneumatic book pressing and clamping mechanism, the machine firmly fixes book blocks during cutting to ensure stable processing. The main servo motor realizes fast and sensitive braking control. Featuring a compact streamlined structure with convenient maintenance, it adopts synchronized dual pull rods and gear transmission to offer high-torque and even cutting performance, with a maximum trimming speed of 15 cycles per minute for continuous book trimming tasks.

This three-knife trimmer is customized to match the production characteristics of digital printing workshops, balancing stable trimming precision and convenient operation. Servo-driven cutter adjustment effectively avoids dimensional deviation during repeated cutting. Pneumatic clamping keeps book blocks tightly fixed, preventing displacement which causes uneven cutting edges. The servo main motor ensures rapid braking to improve operation safety and processing consistency. Its simple mechanical structure greatly reduces daily maintenance difficulty, while dual pull rod synchronous gear drive outputs stable high torque to handle various thickness book blocks smoothly at a speed of 15 cycles per minute.
