C400K-L Long Shaft Processing CNC Slant Bed Lathe

C400K-L CNC Slant Bed Lathe Introduction

the cnc slant bed lathe C400K-L series full-function lathe adopts full guide rail protection, and the cooling box and chip conveyor are separated from the main machine to ensure that the accuracy of the machine tool is not affected by thermal cutting. The electrical unit cabinet of the machine tool has good sealing and is equipped with air conditioning in the electrical cabinet to ensure the normal operation of the CNC system in the high temperature and high humidity environment of the machine tool. The bearing seats at the travel positions in the positive and negative directions of the shaft are equipped with rubber buffers and anti-collision devices to provide final protection for the double-nut ball screw pair from damaging impacts under abnormal circumstances.

1. The lathe uses an hydraulic servo turret with high positioning accuracy, fast tool change time, and minimal deformation under heavy cutting.
2. The transmission system uses linear roller guideways imported from Taiwan to meet the requirements of high speed and high efficiency. It reduces friction resistance and deformation caused by temperature rise, improves the machining accuracy, and ensures the long-term stability of the cutting machining accuracy.
3. Integral fully-enclosed protection makes it durable, with stable operation and low noise. It is superior to similar products in terms of waterproofing, oil drainage, dustproofing and safety performance.
4. The machine with an electrical cabinet has good sealing performance and uses the heat exchanger to ensure normal operation in a high-temperature and high-humidity environment.
5. The chip conveyor (optional) has the advantages of smooth chip removal, compact size, high efficiency, stable delivery, low noise, and overload protection, etc.

Description of the basic structural features of the machine tool

1 Bed

The bed features an integrated 45° slant bed circular cavity cast iron structure, ensuring heavy-duty cutting capability. The bed is cast using high-quality resin sand, offering excellent rigidity, vibration resistance, and smooth chip removal.

2 Spindle Housing

The spindle housing bearings utilize a combination of double-row cylindrical roller bearings and double-direction thrust angular contact bearings, providing high rigidity. The structural design incorporates measures to reduce spindle thermal deformation, ensuring the spindle maintains relative stability along its axis during prolonged operation.

3 Feed System

The X and Z-axis servo motors are directly connected to precision ball screws via elastic couplings, offering high precision. The ball screws are fixed at both ends, enhancing
the support stiffness of the bearing seats, thereby minimizing distortion and deformation caused by frequent high-speed positioning and heavy cutting. The bearings are specialized 60-degree angular contact precision bearings for ball screws, offering high speed and precision.

4 Slide

The transmission system uses imported Taiwanese linear rolling guides to meet high-speed and efficient requirements, reducing friction resistance and temperature-induced deformation, thereby improving processing precision and ensuring long-term stability of cutting accuracy.

5 Tool Turret

The series of fully functional lathes are equipped with 8-12 servo-hydraulic tool turrets. They feature fast indexing positioning, high indexing accuracy, and excellent turning rigidity.
The tool turret is equipped with a central coolant supply function, providing high coolant pressure. The coolant tank capacity is sufficient to prevent coolant flow interruption during machining, and it is equipped with a filtration system for high filtration precision.

6 Hydraulic System

Hydraulic chuck clamping, releasing, and tailstock sleeve extension/retraction can be controlled by both program commands and foot pedal operations, offering convenience and efficiency. Hydraulic pressure adjustment is controlled via panel-mounted rotary knobs with dial displays, ensuring safe and convenient operation.
Hydraulic chuck clamping, releasing, and tailstock sleeve extension/retraction can be controlled via foot pedal in addition to program control, offering convenience and efficiency. Hydraulic pressure adjustments are performed using panel-mounted rotary knobs with dial displays, ensuring safe and convenient operation.

7 Lubrication System

The machine tool employs an automatic centralized lubrication system with timed and metered oil supply. The oil distributor adjusts supply pressure according to the pressure requirements of different lubrication points to ensure adequate lubrication for all lubrication points (such as guideways, inserts, lead screws, nuts, etc.).
A lubrication system alarm function is also provided.

8 Cooling System

The slant bed CNC lathe features full guideway protection, with the coolant tank and chip conveyor separated from the main machine to prevent thermal cutting effects from affecting machine accuracy.

9 Electrical System

The machine tool's electrical unit cabinet has excellent sealing performance and is equipped with an electrical cabinet air conditioner to ensure the CNC system operates normally in high-temperature and high-humidity environments.

10 Limit Collision Prevention Measures

Rubber buffer collision prevention devices are installed on the bearing seats at the positive and negative limit travel positions of the axes to provide final protection for the double-nut ball screw pairs against damaging collisions under abnormal conditions.

11 Safety Protection

The machine tool features a fully enclosed internal sheet metal design and a fully enclosed external sheet metal design, with sheet metal thickness of no less than 2mm. During operation, the machine tool remains free from deformation and vibration.
Internal protective covers made of stainless steel are used for the guideways, lead screws, nuts, and bearings. Chip removal and debris cleanup are convenient.

Main Parts of CNC Slant Bed

Spindle The spindle box bearing features a structure of double-row short cylindrical roller bearings. This configuration enables it to achieve high precision and rigidity, thereby ensuring the long-term precision and stability during heavy-duty cutting operations. Spindle Speed: 3000rpm;2500rpm Spindle Power: 11kW Spindle Taper Hole: Φ62 mm; Ф86mm Headstock Improvements are made to the heat dissipation air duct and heat sink of the spindle headstock, reducing the temperature rise of the spindle box by 15%.
	45° Integrally Slant Bed Structure This structure ensures high stability and rigidity during the machine tool's operation, as well as the stability of mass-produced product quality. With multiple aging treatments, the stability and rigidity of the machine tool are significantly enhanced. Casting Structure Using a circular cavity structure, the machine rigidity is increased by 1/3 with the same load and same machine size.
Integrated Pallet The integrated design of the motor base and the slide plate features excellent strength, which reduces the assembly precision error and ensures the machine's precision. X/Z-axis Travel: 200/500mm; 200/1100mm X/Z-axis Rapid Traverse Speed: 20/25m/min
