The PBM-2500 machine is light weight, just 13 lbs. and is designed to bevel boiler tubes. The tool bits are held in by our optional wedge lock system. The torque accepting mandrel with lock in blades (no springs) easily stops any pieces from dropping down into the boiler tube. Our gear drive unit has spiral bevel gears for better torque (more teeth engagement, compared to standard straight gears that other competitors use).
PBM-2500坡口机很轻，只有约13磅（5.90KG）。适用于切削锅炉行业用的管子，其刀头是由楔形锁紧系统固定。芯轴自锁刀具（无弹簧）可防胀块掉落在锅炉管子里。我们的机器采用螺旋锥齿轮驱动，相对于我们竞争对手使用的直齿轮驱动，螺旋锥齿轮驱动可以提供更大的扭矩。
 
PERbbbbANCE:
• Lock in mandrel blades (no springs to lose) • Adjustable keyway on machine and mandrel (eliminates backlash and chatter) • .75 hp pneumatic motor • 13 lbs. approximate working weight • Hardened mandrel 55 Rc. (less chance of gouging with bbbbl chips) • Tool bit is held in by our wedge lock system (keeps the tool bit locked in the cutter head to ensure chatter free bevels) • Single mandrel with mandrel blades to cover size ranges
