Q:Which brand is straight rail?

The most cost-effective is on the HIWIN, the mainland market share of the largest.Japan THK higher precision, materials and workmanship is relatively good, in the international market share of the forefront.German Rexroth (formerly German STAR) brand, the price and THK equivalent, high precision, but advertising is not as good as THKIn addition, there are many brands, such as Taiwan, ABBA, Japan, NSK, Korea SBC, are well-known brands in the world.Brand which is not good, mainly depends on the demand, the most suitable is the best.

Q:3 axis painting manipulator we manufacture, three axis parts are installed around the linear guide in Taiwan silver by the beam, the linear guide 1500, on a series of bolt spacing 100 counterbore, connected by six angle bolts and frame. On the linear guide hole due to the relatively dense, a hole painting is the main line we tapped due to the quality of the reasons often centredistanceofhole difficult to ensure that the mounting rails around there are parallel degree error guide to sports bad, want to ask Master is similar to the structure is how to deal with.

Upstairs said yes, your rail installation in the face of wrong ah? If you don't even have a baseline, it's a waste of the linear guide. This is not the most important relationship with the screw hole position. It is important to install the mounting surface of the linear guide rail. The bottom of the rail must be machined with straightness, and then a side must have a datum plane, which can be used as a benchmark for either the inside or the outside of the two rail. But in the assembly, they can not do the benchmark, the first step is to measure the verticality of the bottom surface of the guide rail straightness and the bottom surface and the side of the rail, and leading after the installation, and side gauge parallelism and two gauge high (parallel horizontal), how do you measure?

Q:What lubricating oil should be used for elevator lubrication?! What brand?. What's the number?.

With No. 68 rail oil, it is best to use some better.

Q:How to choose linear guide rail?

Each manufacturer has a selection manual for selection, and if you need to type, please consult the brand's dealer or agent. If it is used in large quantities, you can contact the manufacturer or general agent

Q:How can the dovetail guide be fixed on the case?

With the servo motor, the motor is locked, then guide the tightening. If you are stationary, place a few screws on the side and press the adjusting block. If you want to move, you have to add a mechanism...

Q:Excuse me, what do you mean by interchangeability and non interchangeability?

The interchangeability of sliding blocks between different rails is called interchangeability

Q:How to determine the mounting position of the guide bracket?

Determine the mounting position of the guide bracket:1, no rail support, pre buried iron elevator shaft lining, according to the requirements of the drawing guide bracket spacing, size and installation of the rail support vertical to determine the location of the guide rail in the wall.2, when the drawing does not specify the next row guide rail bracket and the top row of the rail bracket position should be determined according to the following provisions: the next row guide bracket is arranged at the position corresponding to the pit decoration above the ground 1000mm. The top row of racks shall be installed below the roof of the hoistway, no more than 500 m M.3, in determining the position of the guide bracket at the same time, but also consider the rail connection plate (link plate) and a guide rail bracket cannot collide. Staggered net distance is not less than 30m M.4, if the drawings are not clearly defined, the lower level rail support shall be taken as the basic point, and every row of the rail bracket at the top of every 2000mm. Elsewhere (in case of said plate) spacing can be properly enlarged, but should not be greater than 2500mm.5, longer than 4m (including 4m) car rails, each should have at least two rail brackets. 4m to 3m long car rail is not subject to this limit, but the spacing between the guide brackets shall not be greater than 2m. If the manufacturer's drawings are required, they shall be constructed according to their requirements.

Q:Method for calculating theoretical weight of elevator guide rail

The elevator rails are divided into three major categories: solid rail, counterweight hollow guide rail and escalator rail.Solid guide is machined by rail, rail profile machined surface oriented and connecting parts together, its purpose is in the elevator for the operation of the car to provide guidance, solid guide small size is also used for redirection.Solid rail specifications are many, according to the weight of each meter can be divided into: 8K, 13K, 18K, 24K, 30K, 50K, etc., according to the width of the rails, the bottom can be divided into T45, T50, T70, T75, T78, T82, T89, T90, T114, T127, T140 and so on.You can refer to the following table (sorted by rank):Theoretical quality of rail formed steelModel sectional area / cm3 theoretical quality / (kg / M)T75 13, 1O.205T78 11.752 9.225T82 12.994 10.200T89 17.873 14.030T90 20.453 16.056T114 24.312 19.085T125 25.452 19.980T127-1 25.442 19.972T127-2 31.735 24.912T140-1 38.200 29.987T140-2 46.826 36.758T140-3 61.500 48.278

Q:CNC lathe guide and how to select the screw, to be detailed!

1) compared with the sliding screw, the driving torque is 1/3Because there are many ball bearings between the screw shaft of the ball screw pair and the silk mother, the rolling motion can be achieved, so the higher movement efficiency can be obtained. Compared with the past sliding screw pair, the drive torque is less than 1/3, that is, the power required to achieve the same movement result is the 1/3 of the rolling screw pair. It's very helpful in saving electricity.2) high accuracy guaranteeThe ball screw is for mechanical equipment made in Japan, the world's highest level of coherence produced, especially in grinding, assembly, inspection of the operations of the factory environment, carry out strict control of temperature and humidity, due to the improvement of the quality management system to guarantee the accuracy.3) micro feed possibleBecause of the ball motion, the starting torque of the ball screw pair is very small, and the crawling phenomenon like sliding motion can not occur, and the accurate micro feed can be ensured.4) no backlash, high rigidityThe ball screw can be added to the pressure, pressure due to the axial clearance can reach negative, then get high rigidity (ball screw in the ball through to add to the pressure in the actual use mechanical devices, because the ball screw can make the repulsion of the rigidity of the Department of enhancement).5) high speed feed possibleBecause of the high efficiency and small heating, the ball screw can achieve high speed feed (movement).

Q:Is it a ball screw or a straight guide?

See what you use on the occasion, such as ball screw and linear guide combination, in the linear module, the use of the implementation of two different functions, indispensable, according to no comparability. Look at the picture below... The linear module manufacturer answers for you.
