The products enjoy a high reputation at home and abroad and are exported to more than 40 countries and regions around the world. The "Plissen" trademark has been registered in 44 countries. The rotation diameter of lathe products ranges from Φ260mm to Φ3500mm, and the length of the workpiece processed can be up to 20m. The leading products have been rated as famous brand products in Shandong Province. Among them, ordinary lathes adopt a bearing structure, which has good vibration resistance, stable product quality, strong reliability, and wide application range. CNC lathes are divided into simple CNC, economical CNC and full-function CNC, which can meet the requirements of users at different levels. Especially the full-function CNC has the characteristics of high rigidity, high precision and high speed, and can better realize the use of turning machines instead of grinding machines. The processing has reached the domestic advanced level. Products have also developed from light to heavy, with sleeping cars with a rotation diameter of more than 1000mm, load-bearing from 6t to 80t, a maximum processing length of 20m, and a maximum rotation diameter of 3.5m. The CK61100D CNC lathe has a load capacity of 6t, the CK61125L CNC lathe has a load capacity of 10t, the CK61200W series has a load capacity of 20t, the CKZ series has a load capacity of 30t, and the CKG series CNC heavy-duty trolley has a load capacity of 40t, 60, and 80t. Deep hole products are mainly used for drilling, boring, rolling and honing. The processing diameter ranges from Φ1.5mm to Φ1250mm, and the length specifications are complete. The length of deep hole processing can be up to 15m. Our company's deep hole products are unique in the country, filling many domestic gaps, and our technology level and market share are in the leading position in the country.
