2.Overview of Machine Tools

 

2.1 The processing range of the machine tool

Drilling range：Φ25～Φ100mm

Boring range：Φ40～Φ200mm

Range of workpiece outer diameter：Φ60～Φ400mm

 

2.2 Machine tool functions

Drilling and boring functions.

Drilling：BTA drilling method,where the cutting tool is moved backward to remove chips.

Boring：Push drilling method,removing chips forward through the bottom hole of the workpiece.

 

2.3 The main structure of the machine tool

2.3.1 Main components of the machine tool

Bed body, bed head box, oiling device, tool holder bracket, drill pipe box, sliding guide rail, gear rack, cooling system, control system, electrical box, workpiece support frame, etc.

 

2.3.2 Workpiece clamping

The manual three-jaw chuck on the headstock holds one end of the workpiece, while the oiler cone plate automatically clamps the other end of the workpiece.

 

2.3.3 Machine tool control system

Control system：PLC

Z-axis：Longitudinal feed motion of the drill pipe box,the servo motor drives the gear rack mechanism through a reduction mechanism.

X-axis:The oil dispenser servo tightens the workpiece,and the servo motor drives the gear-rack mechanism through a reduction mechanism.

 

2.3.4 The basic components such as the box body, bed body and support plate are precisely cast from high-quality cast iron. After casting, they undergo two stages of aging treatment to eliminate internal stress, stabilize the structure and dimensions, and improve mechanical properties.

 

2.3.5 Bed frame

The bed body is made by resin sand casting and undergoes normalizing treatment after casting. The bed body is of a split structure, assembled together using high-strength bolts and positioned by conical pins.

It adopts double rectangular sliding guide rails, which are precisely ground and have high hardness on the guide rail surface after quenching.

The bed body is equipped with inclined gear racks for tool feed transmission, and the gear racks are precisely processed and quenched. The machine tool has a large load-bearing capacity, sufficient rigidity, and stable transmission.

Internal to the bed body, V-shaped inclined ribs are arranged, providing strong support and being less prone to deformation; the outer wall of the bed body directly supports the guide rails, and the guide rails can withstand large cutting forces. The guide rails have good rigidity and are less likely to deform or shake during processing, which is beneficial for improving the processing quality and efficiency of the machine tool.

Oil return grooves are cast around the bed body, and oil return covers are installed on the grooves. The cutting oil on the bed body automatically returns to the cooling oil tank.
