2m Processing Depth Deep Hole Drilling Boring Honing Machine
We are a professional manufacturer of deep hole processing machines with over 10 years of experience. Our TMK2130×2m deep hole boring and honing machine integrates drilling, push boring, pull boring and honing functions. Adopting world-renowned brand core components and strict production standards, this machine features high rigidity, stable performance and excellent machining accuracy. It is widely used for deep hole processing of various cylindrical workpieces and exported to more than 50 countries worldwide. Custom configuration and reliable after-sales service are available for global clients.
Description
Machine Overview
TMK2130×2m deep hole boring and honing machine is a multifunctional integrated equipment specially designed for cylindrical workpieces. The whole machine is divided into three main sections: honing section, workpiece clamping section and drilling & boring section. It can complete a full set of processing procedures including drilling, push boring, pull boring and honing in one clamping.
The machine supports BTA drilling technology, as well as push boring and pull boring processing methods. The honing unit is controlled by servo motor, which can work under constant pressure mode or constant displacement mode. It is capable of overall honing and local honing to effectively correct workpiece taper, ovality and aperture errors. The tool can rotate and feed, while the workpiece can be set to rotate or keep stationary according to processing demands.
For the control system, drilling and boring processes are controlled by SIEMENS-828D CNC system, and the honing process is managed by PLC system. Different types of oil are applied separately: special honing oil for honing work and professional deep hole cutting oil for drilling and boring.
Core Structural Advantages
The whole machine bed is made of high-quality HT300 cast iron, which is processed by multiple aging treatments to eliminate internal stress, ensuring stable structure, high rigidity and long service life. The guide rails adopt precision grinding and quenching treatment, with good wear resistance and load-bearing capacity. The rack and pinion for transmission are precisely machined and heat treated to realize smooth and stable operation.
The honing spindle box is driven by servo spindle motor through gear reduction. All gears are precision ground and high-frequency quenched, with high strength and wear resistance. The spindle adopts combined bearings to bear large axial and radial forces and maintain high running accuracy. The honing bar is supported by fixed and movable rests to reduce vibration during operation.
The workpiece section is equipped with through-type headstock and closed annular center frame. Both ends of the headstock spindle are fitted with four-jaw chucks to clamp workpieces firmly. The closed center frame adopts three-point supporting structure, which can adjust freely to fit workpieces of different outer diameters.
The drilling and boring section is equipped with professional oil pressure head, drill box and drill bar support rest. The oil pressure head plays the roles of tool guiding, oil supplying and auxiliary supporting. The drill box uses manual three gears with stepless speed regulation in each gear. All sliding parts are equipped with independent automatic lubrication system with liquid level alarm function, which can effectively extend the service life of components.
Complete Protection & Lubrication System
This machine is equipped with comprehensive safety protection devices, including lubrication oil shortage protection, cooling liquid level and pressure protection, motor overload protection, feed load protection and travel limit protection, to ensure safe and stable operation.
The lubrication system is arranged in different areas according to functional modules. The guide rails and sliding blocks are lubricated by automatic lubrication stations. Gears and bearings inside each spindle box adopt circulating oil lubrication. Some auxiliary moving parts are equipped with manual lubrication pumps for daily maintenance.
The cooling and filtering system is fully configured with multiple pumps, large-capacity oil tanks, magnetic roller filters and paper tape filters. The pressure, flow rate, temperature and liquid level of cutting oil can be displayed digitally on the operation panel, making monitoring and operation more convenient.
