Product descripation:
The WXC series of center-less lathe and JY series of straightening machines are high -level new equipment with independent intellectual property rights on the basis of absorbing and digesting foreign advanced technology, making adventurous innovation, and research&development take into consideration of actual situation of domestic companies. Our technology reaches the domestic advanced level in reliability and quality while keeps a relatively lower price, with its efficiency more several times than the conventional process.
Our products are suitable to process different kinds of metal material, for instance, black metal material such as structural steel, alloy steel, spring steel, bearing steel,tool steel, copper and copper alloy, aluminum and aluminum alloy, magnesium alloy, titanium and titanium alloy and other non-ferrous metal materials.
WXC series of centerless lathe is high-efficient specialized lathe to make a rough or fine machining to the surface of bar material such as slender shaft and other bars. It is able to not only get rid of the imperfection on the bar surface , de-carburized layer, crack etc, but also to guarantee relatively high accuracy. It is especially suitable to process extra long bar and bar with large machining allowance.

Noted: ①The smaller the bending degree of raw material, the better finished product's precision, and the longer machine service life and higher efficiency. If straightness of raw material is too large, it has to be straightened before peeling, or the precision, machine service life and working efficiency will be effected. When the straightness of raw materials is large, manual feeding is required.If the ends of raw material has serious trimming, flat head and bending, it has to be cut off before peeling.The bending degree of finished product will be big when the diameter is less than 20.

Composition of Peeling Machine:
The equipment is usually composed of main machine and the table bed.
1.Main machine
consists of bed,spindle, air/oil lubrication system,front-clamping feeding system,rear-clamping extracting system,front guide and middle-rear guide system,etc.
2.Table bed
consists of the loader and unloader.
3.The air/oil lubrication system
The air/oil lubrication system is specially designed to lubricate and cool the spindle bearings during their highspeedrotation. It is composed of pump, oil and air distribution block and air source processing unit.
4.Cutting fluid circulation cooling system
Cutting fluid circulation cooling system consists of circulating water pump, pipeline, nozzle,etc.The cooled cutting liquid is taken by the water pump from reservoir to the nozzle nearthe cutter head through pipeline and sprays on the tools and scraps. Thus it takes away the cutting heat and drops into chip mouth with the scraps under the cutter head and flows back to the reservoir through the pipeline to be cooled again.
5.Chip conveyor
Chip conveyor is provided by our outsourcing supplier. The scraps falls onto the chain plate through the chip mouth under the cutter head and they are taken out by transmission and collected intensively.
6.Hydraulic system
consists of motor pumps, control valves, hydraulic oil tank, hydraulic pipeline etc.Clamping and loosening bars are realized through the cylinders in the front-clamping feeding and rear-clamping extracting systems.
7.The electrical system
The electrical system includes power supply system and controlling system, integrated by 1 power distribution cabinet and 1 button station,realizing the electric control of the main transmission, front- clamping feeding system, rear- clamping extracting system,cooling system, hydraulic system, conveyor and the table bed.
