Bi-directional spindle clamp seat.Bi-directional spindle clamp seat

Product characteristics:

It can be processed at both ends simultaneously, with double efficiency of "zero" concentricity at both ends, greatly reducing the volume and cost. It is a special tool for shaft and tube machining and a higher speed design to perfectly solve various processing requirements. It greatly reduces the length of the spindle. For short material processing, retractable and knife-type designs solve the length limitation of the spindle and make automatic feeding at the rear easier. The configuration of extended head and the use of movable two-set spindle clamping completely solve the double-head machining of super-long workpiece. The latest cartridge clamp design is super-large clamping stroke, which perfectly solves the clamping problem of large tolerance workpiece. (Special clamp products can be designed separately for customer products and processing characteristics)
Product application: two-end special turning machine, spindle, shaft and sleeve processing. It is widely used in automobile, electromechanical and other manufacturing industries involving shaft applications.

RemarksSelect the spindle type:
1. First, the diameter and length of the product to be processed should be considered, and the spindle type suitable for clamping through holes should be selected.
2. Depending on the product roundness requirement, the concentricity of processing positions at both ends, and the requirement of clamping position and processing position, select the spindle that can meet the requirement.
3. When the diameter is smaller, select the spindle with high speed. If the customer needs more rotational speed of the spindle than listed in the table above, then select the bearing according to the actual situation.
4. The workpiece being processed is of softer material and more easily deformed (thin-walled pipe, copper and aluminium parts), the air press spindle must be selected.
5. Customer-specified cylinder clamping stroke can not exceed 2mm. Only the main shaft above JHP-120 can increase the clamping stroke at present. Specifically, the detailed analysis needs scheme.
6. To see if there is any axial positioning requirement for the workpiece, choose push-ahead type, add axial positioning plate or double-piston main shaft.
7. See the length of workpiece: shorter workpiece needs single-cylinder clamping, and shorter workpiece can be clamped by double-cylinder clamping. Due to the limitation of the width of the spindle, do you want to make the indented cutter penetrate the through-hole of the spindle and let it work? Does the long workpiece have single spindle and extension sleeve? Whether two sets of spindles are used for extra-long workpieces.
8. The overall selection of spindles needs to consider the compatibility of various diameters and length specifications of end-user products to select product options.
9. Evaluate process requirements and tool holder configuration, and self-simulate tool feed interference according to spindle size and installation angle.
