Product Description

You are welcomed to come to our factory to buy the latest selling, low price, and high-quality NERES Hydraulic Thru Feed Thread Rolling Machine. We look forward to cooperating with you. Hydraulic infeed thru feed  use two roller rollers to roll screws. This process provides the benefits of thread forming by replacing cart-cracking or grain cutting with an effective cold grain melting process.

Hydraulic Thru Feed Thread Rolling Machine can not only produce the screws more quickly and accurately, but also have higher tensile and shear strength than the machined pear thread produced by cutting method .

This is because the rolling screw is formed by the flow of metallographic crystals, the internal group of lines more shaped mesh window, smooth surface hardness, and knot saving material.

Material, no chips, greatly reduce the cost of processing time.

Heavy duty rolling through fixed dual-use oil press tooth roller.

1. Strong structure: the left frame and the right frame form an L-shaped assembly structure with strong resistance and good rigidity

2 precision stability: double oil pressure system, PLC program control, processing quality average more stable

3 oil pressure channel strong: piston type and blade type

4. The gear box is installed with the function of adjusting tooth backlash, the rolling work size conversion, and the function of debugging spindle tolerance

5. Long life: the main parts of the machine: universal joint, frequency converter, hydraulic system, micro dynamic switch, long working life, processing products more stable
