A bench warrant is issued by the court after a defendant fails to appear at a previously scheduled appearance.
Usually, your attorney can make arrangements for you to surrender on the bench warrant. He or she can call the prosecutor and explain you want to turn yourself in and they can agree on a date. They may also advise the court that you will be turning yourself in on that date.
When you appear in court for the bench warrant, your attorney can present the reasons for your failure to appear on the initial date in a light favorable to you.
The judge, at that point, can reinstate your bond and you will be free to leave at the end of the hearing.
If you turn yourself in on your own, you may face a greater risk of being held in jail pending a hearing and some uncertainty as to whether the judge will agree to reinstate your bail.
I highly recommend that you retain experienced counsel in your jurisdiction to assist you with this process.
