Abstract
The utility model relates to a machine tool part and relates to a screw rod containing a diamond-like carbon (DLC) coating. The screw rod containing the DLC coating comprises a screw rod body, wherein one DLC coating is arranged on the screw rod body; the screw rod body comprises a screw section; the DLC coating is arranged outside the screw section; and the DLC coating has the thickness of more than 1 mm. The screw rod has the advantages of wear resistance, durability and low cost.
Description
Technical field
The utility model relates to machine tool component, particularly relates to a kind of leading screw of lathe.
Technical background
Leading screw is connecting feed screw nut, is driving the motion of cutter or work piece platform, and the material of leading screw is that converted steel is processed, and has certain wear resistance, but long-term use still has wearing and tearing, in the existing technology; Leading screw is the material of one, does not promptly establish wearing layer, and the material of usefulness is too senior can to increase cost.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned shortcoming, and a kind of wear-resistant, durable in use, leading screw that cost is low is provided---contain the leading screw of DLC coating.
The technological scheme of the utility model is achieved in that the leading screw that contains the DLC coating, comprises the leading screw body, it is characterized in that: be provided with one deck DLC coating above the described leading screw body.
Say that further described leading screw body includes the silk section, described DLC coating is having silk section outside.
Preferable technological scheme is: described DLC coating is greater than 1 millimeter.
The beneficial effect of the utility model is: such leading screw has the advantage wear-resistant, durable in use, that cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model leading screw.
Wherein: 1, leading screw body 2, DLC coating 3, silk section is arranged.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, contain the leading screw of DLC coating, comprise leading screw body 1, it is characterized in that: be provided with one deck DLC coating 2 above the described leading screw body 1.
DLC be a kind of by carbon constitute, similar in nature with diamond, have simultaneously the material that the graphite atom is formed structure again.DLC film (DLC) is a kind of noncrystalline membrane, owing to have high hardness and high elastic modulus, low friction coefficient, wear-resistant and good vacuum tribological property is well suited for as wear resistant coating.
Say that further described leading screw body includes silk section 3, described have silk section outside that the screw thread silk is arranged, and this is the place of feed screw nut motion, and described DLC coating is having silk section outside.
Preferable technological scheme is: described DLC coating is greater than 1 millimeter.
Claims (3)
1. the leading screw that contains the DLC coating comprises the leading screw body, it is characterized in that: be provided with one deck DLC coating above the described leading screw body.
2. leading screw according to claim 1 is characterized in that: described leading screw body includes the silk section, and described DLC coating is having silk section outside.
3. leading screw according to claim 1 and 2 is characterized in that: described DLC coating is greater than 1 millimeter.
